Winds of change as Ethiopia harnesses ecofriendly power

ADAMA, Ethiopia–The wind blows hard over Adama, a range of rocky hills in Ethiopia’s highlands that provide the perfect location for one of the continent’s largest wind farms.


“In February, during the dry season, it is even difficult to stand here,” said Solomon Yismaw, the engineer in charge of 102 Chinese-built turbines each rising 70 meters into the sky, lining the horizon.


The Adama wind farm opened last month, its 153 megawatt (MW) capacity making it the largest wind farm in sub-Saharan Africa, and the latest of three giant Ethiopian wind farms.


The hills here, 100 kilometers (60 miles) southeast of the capital Addis Ababa, are 2,000 meters high.


Farmers using simple ox carts to plough the soil around the bases of the wind turbines offer a striking contrast between rural lives, little changed for centuries, and the central government’s ambition to develop a modern, climate-resilient economy.


Without its own reserves of either gas or oil, Ethiopia is turning to its significant renewable energy potential to fuel its rapid economic development — including damming the vast Blue Nile, with turbines there providing over 90 percent of the country’s electricity production, and the southern Omo River.


But the flow of rivers is subject to rainfall that is erratic in Ethiopia.


“We have an abundance of hydroelectric energy sources, but during the dry season and when droughts happen the level of the dam decreases,” said Solomon, who pointed out that the wind turbines were immune to the dry spells.


Massive Power Needs


“At that time the wind will complement the dam. The wind is especially strong during dry season, so wind and hydro complement each other,” said Solomon.


Ethiopia’s energy needs are huge. Over 75 percent of Ethiopia’s 94 million people, mainly those living in rural areas, are not connected to the national grid, and the country needs to increase its electricity production by 20 to 25 percent per year to meet rising demand, according to figures from the country’s energy ministry.


Ethiopia has set a target of slashing its carbon emissions by two-thirds within the next 15 years, the most ambitious national goal yet presented to an upcoming United Nations climate change conference in Paris later this year.


Ethiopia said it plans to cut emissions by adopting cleaner practices in agriculture, construction and transport, as well as slowing deforestation.


While work continues on the vast Renaissance dam on the Nile — the largest in Africa — Ethiopia is working to boost other green power projects, harnessing geothermal, solar and wind energy.


“Wind farms are fast track projects, we can construct them within a short time,” said Tahaguas Andemariam, consultant engineer and professor at the university of Adama.


“Within 24 months we have constructed this big wind farm of 153 MW — hydro would have taken much longer,” he said.


The 6,000 MW that the Renaissance dam will generate will dwarf the output of the Adama wind farm, but the construction of the facility which began in 2011 isn’t slated to finish until 2017.


Yet the Adama wind farm can still power about 10 million efficient light bulbs.


Another wind farm, even larger in size and intended to produce 300 MW, is due to be constructed at Ayesha in the remote eastern desert near the border with Djibouti, another area with strong winds.


“We now have the knowledge how to develop the roadmap of this wind technology in Ethiopia,” said Tahaguas, who spent a month in China working with other engineers to learn more about the turbines.

Michigan utilities work to comply with air pollution rule



Updated 1:13 am, Sunday, June 28, 2015



LANSING, Mich. (AP) — The U.S. Supreme Court is expected to release a decision this week about new mercury and toxic air emissions standards for power plants, but Michigan’s utility companies have already been working toward compliance.


The case against the U.S. Environmental Protection Agency is led by Michigan, which was joined by 20 other states.


The justices will take the bench again Monday to hand down more opinions. They should finish their work early in the week. In rare instances, the court will put off decisions and order a case to be argued again in the next term.


The main issue is whether the EPA was required to take costs into account when it first decided to regulate air pollutants from power plants or if health risks are the only consideration under the Clean Air Act.


The EPA estimates costs of around $9.6 billion for power plants to install and operate equipment to remove pollutants in accordance with the rule.


Attorney General Bill Schuette‘s spokeswoman Andrea Bitely said Schuette “pursued this case to the top because it was an obvious overreach by the federal government.”


“Michigan’s fragile economy cannot afford the job losses and skyrocketing electricity rates that would accompany the premature implementation of this new federal regulation,” she said.


But while the case has been making its way through the courts, the state’s utility companies have taken steps to comply with the rule. Michigan’s two largest utility companies, Consumers Energy and DTE Energy, declined to comment on the case itself. Representatives for each said they are working to ensure their compliance with the rule will not result in layoffs.


Linda Hilbert, executive director of environmental services for Consumers Energy, said the company has been working on compliance since the rule was finalized in February 2012. It took effect in April of this year.


“The last thing we want is to be out of compliance,” Hilbert said.


Unlike past rules under the Clean Air Act, where Consumers was able to meet requirements through cap and trade programs, the utility has been installing pollution control equipment on coal-fired units to meet specific limitations.


“It was very, very cost prohibitive,” Hilbert said.


That’s part of why Consumers will retire seven of its coal-fired units across the state in cases where it didn’t make sense economically to add the pollution control equipment, said Dan Bishop, director of media relations for the utility.


Bishop said the company is working to place workers from the retiring coal-fired units within the company where possible.


“As far as electricity prices, we’re committed to keeping cost increases below the rate of inflation, and are doing so,” he said.


DTE Energy also plans to retire at least two coal-fired units in the state due to old age and the implementation of the air pollution rule. All of the company’s plants will meet the standard by April 2016, said DTE senior media relations specialist Erica Donerson.


Donerson said DTE has pledged that no employees will be laid off as part of its transformation. Donerson added that DTE can’t predict the impact of all these changes on rates, but said, “To recover the generation lost due to plant retirements, DTE will utilize natural gas and renewable energy sources. Whenever we purchase or build new generation, those costs become part of the rate base.”

Freedom Act would allow third-party sales of solar power in NC



Several proposed changes in solar energy law await action in the General Assembly’s current session, including the Energy Freedom Act, which could make Faith Community Church’s challenge to the status quo unnecessary.


The Greensboro church has joined with NC WARN, an energy activist group, to challenge a rule enforced by the N.C. Utilities Commission that prevents solar companies from selling the power generated by their equipment to the people who buy or lease equipment from them.

Google to Open New Data Center in Alabama

June 25, 2015 | The New York Times | Quentin Hardy


Plans to take a retired coal power plant in Jackson County, AL into the future were announced today by the Tennessee Valley Authority (TVA). The site will house Google’s new data center.


According to The New York Times, Google has also made a deal with the TVA to locate and bring online new renewable energy projects in the area:



 “Data centers are attractive customers” to power suppliers, said Urs Hölzle, Google’s senior vice president for technical infrastructure.



In light of new EPA clean air rules that would require significant retrofits and investment in the Widow’s Creek coal-fired plant, the TVA board of directors approved a closure earlier this year. The new data center project will be ushered in with a $600 million investment from Google. Google has bought significant amounts of renewable energy since 2010.


Earlier this year Inside Energy reporter Leigh Paterson reported on ways data centers are going “green,” explaining that data center energy use is growing: “In 2013, data centers represented more than 2% of total US electricity consumption.” With their intent of re-purposing the existing coal plant infrastructure, Google is no exception.


Google has several data center expansions underway, in the U.S., Singapore and Belgium.


The investment also mitigates risk, according to Google’s Joe Kava, who leads data center construction:



 By having several construction projects underway…the chances of a shortfall in overall capacity from a slowdown at one project were minimized.



The selection of Widow’s Creek came after much research, and is part of a 100% renewable energy goal set by Google.

Solar Energy Corp of India converted into commercial entity

Solar Energy Corp of India converted into commercial entity

India’s installed renewable power capacity is 35,776MW, of which the share of solar power is 3,743MW.




New Delhi: State-run Solar Energy Corp. of India (SECI), formed in 2011 with charitable objectives, will be converted into a growth-oriented commercial company that will generate and sell solar power and develop other sources of renewable energy, the Union cabinet said Wednesday.


With an eye on expanding India’s renewable energy sector and streamlining it, the cabinet also approved renaming SECI as Renewable Energy Corp. of India (RECI).


The move will result in the company becoming a self-sustaining and self-generating organization with its own solar power plants that will generate and sell power. It will also lead to the company expanding activities in other segments of solar power, such as manufacturing of solar products and materials.


The decision to convert SECI from a Section 8 company to a Section 3 one under the Companies Act, 2013, was taken by the cabinet led by Prime Minister Narendra Modi at a meeting on Wednesday.

Section 8 provides for creation of companies with charitable objectives, prohibiting commercial activity and business growth.


In comparison, Section 3 provides for companies mainly for commercial activities that will help the company grow.


“A Section 8 company can only engage in activities of promotion of commerce, art, science, social welfare, sports, education, research, religion and charity, but not commercial activity leading to trade, buying and selling resulting in profit and distribution of dividend,” the government explained in a statement.


The cabinet last week formally approved a decision to increase India’s solar power generation target from 20,000MW by 2022 to 100,000MW by the same year.


The National Democratic Alliance (NDA) has been pushing for growth in India’s renewable energy sector. India’s installed renewable power capacity is 35,776MW, of which the share of solar power is 3,743MW.


Once the firm is renamed, it will expand its scope of activity beyond solar power to take up development of all kinds of renewable energy sources such as geothermal, off-shore wind and tidal.


The decision to enlarge the scope of SECI’s activities covering all renewable energy sources was taken “with a view to provide a comprehensive and optimized solution for generation of renewable energy integrating various renewable energy sources”.


“The generation profile of solar, wind and small hydro has complementarity, and generating power from these sources is likely to be more uniform. This will also reduce stress on transmission and distribution networks, resulting in better grid management,” the cabinet statement said.


Registered in September 2011, SECI has initiated activities for setting up solar power plants, as also for the promotion and commercialization of solar energy technologies. For the first time, during the last financial year, SECI made a profit of about Rs.12 crore. It is expected to touch the profit mark of around Rs.300 crore this year.


Experts said the government’s move was long pending but were unsure about its effect on India’s manufacturing capability in the sector.


“We have argued that SECI needs to be made more strategic. It has a dual role—of an investor and of an intermediary to sign the contracts with other project developers from the government. For now, the move signals SECI having a more central role in the overall solar ecosystem in India,” said Arunabha Ghosh, chief executive officer of Council on Energy, Environment and Water, a policy research institute.


“As per our calculations, to meet the 100GW target we would need to import $36 billion worth of solar panels and modules (given our current manufacturing capacity). But if built up incrementally, we can bring down imports to $16 billion. So, there is a significant opportunity to boost manufacturing.”

UK offshore wind can be cost-competitive in a decade - Dong

LONDON The cost of offshore wind energy in Britain can become competitive with more established forms of energy in the next decade through better technology and bigger turbines, a Dong Energy executive told Reuters on Wednesday.



Offshore wind is one of the most expensive renewable energy technologies in Britain, because manufacturing and maintaining turbines strong enough to withstand marine environments is costly. The sector still relies heavily on government subsidies.



The companies want to reduce the cost of generating electricity to 100 pounds ($156.83) per megawatt hour (MWh) by 2020 from around 140 pounds/MWh now. That compares with a cost of around 90-100 pounds/MWh for new nuclear power.



“Offshore wind has only really been going for 10 years in Britain and is still a growing industry,” Benjamin Sykes, vice president and head of asset management at Dong Energy said in an interview at an industry conference in London.



“You have to look at when it will become cost-competitive with other energy sources, and we think we can get there sometime in the next decade,” he said.



Danish utility Dong Energy is Europe’s largest developer of offshore wind farms. It has 10 operational wind farms in Britain, two under construction and more projects in development. On Wednesday, it announced it would build another 580-megawatt (MW) wind farm off the east coast of Britain, which should be commissioned in 2018.



Dong is putting pressure on suppliers to cut offshore wind costs to 100 euros/MWh for investments from 2020.



To help drive costs down, the company favours giant wind turbines, such as the 8-MW Vestas which is already twice the size of the current standard.



It says these are cheaper in the long run because they only need one foundation, one subsea cable and less maintenance to produce the same power as two medium-sized turbines.



“We expect turbines to get even bigger and the blades to get longer, which will drive more efficiency. I wouldn’t be surprised if we see turbines of 10 MW capacity in the next 10 years,” Sykes said.



Special vessels to transport and assemble the huge turbines offshore are emerging, as well as technology breakthroughs for deeper foundations.



However, offshore wind investors in Britain also need more clarity on government support for offshore wind from 2021, after current support mechanisms end, he added.



Last week, the government decided to end direct subsidies for onshore wind a year early, in 2016, so that more money was available for other, less-established renewable technologies, such as offshore wind.

Compass pioneers EcoCooling in New Zealand

Efficiently maintaining the operating temperatures of powerful computers is one of the major challenges facing data centre operators today.  In a bid to combat this, telecommunications provider, Compass Communications, has introduced EcoCooling technology at its new Te Rapa facility.


EcoCooling is up to 90% more efficient than traditional air conditioning systems, reducing power consumption and delivering a more environmentally friendly facility. Best of all, it does this using nothing but air and water, and has no moving parts.


While it sounds almost too good to be true, it has been proven in over 200 data centres around the world.  


Steve McCarthy, CNS Operations Manager for Compass, says, “Traditional data centre cooling uses lots of chilled water which in turn uses a lot of power. EcoCooling, on the other hand, uses filtered fresh air and tap water. Now, for the first time, EcoCooling is being put to work in New Zealand, resulting in a data centre which costs less to run.”


Produced by a United Kingdom-based company, the EcoCooling system leverages the principle of evaporative cooling; when water evaporates, heat is absorbed and the temperature drops (a principle which is at work to cool us when we sweat).


The EcoCooling system draws in fresh air, filters it and measures the temperature; if it is too cool, the incoming air is mixed with exhaust air from the data centre. Too warm, and the air is cooled through the evaporation of water, which is supplied into the system at normal mains pressures. Air of the appropriate temperature is then circulated into the servers and other equipment within the data centre.


“A cold air containment system is in place, with ducting above, feeding cool air into the front of the equipment. Hot air is extracted and vented, or reused in the system if required,” McCarthy adds.


McCarthy points out that the traditional perception that data centre equipment requires cold air has given way to an understanding that continuous flow is what is required. “If that air is between 23 and 26 degrees, with controlled humidity, it is quite suitable,” he says.


As to why more local data centres aren’t yet using EcoCooling, McCarthy says operators of such facilities are quite conservative, and for good reason.


“You don’t want any surprises in a data centre, particularly with something as critical to effective operations as cooling. However, EcoCooling is proven internationally; in some data centres, its introduction has not only reduced power consumption, but also resulted in the closing down and removal of traditional refrigeration equipment, freeing up floor space. That means the ability to add more servers and grow the capacity of the data centre,” he says.


With electricity high among the costs of any data centre, the new Compass facility enjoys advantages unique in New Zealand thanks to its EcoCooling, which McCarthy says reduces operating costs by up to 25%, offsetting to some extent the considerable capital investment involved in establishing a new data centre.


The Te Rapa facility is Compass’s second data centre and is in the final commissioning stage, with space already being booked up.  Designed as a Disaster Recovery site, it complements Compass’s existing Auckland site or any other hosting site for high availability configurations.

The energy revolution that has 1 percenters shaking in their boots


When you hear about Richmond, California — on the environmental beat, at least — it’s usually in the context of the Chevron oil refinery, one of the country’s biggest, that casts its long shadow over the city. There was the fire and explosion in 2012 that sent toxic fumes into the surrounding Bay Area. There are the continuing worries about the long-term health effects facing the people who breathed those fumes in. There’s the everyday air pollution, and the everyday risk, that comes from living in the refinery’s vicinity and, more quietly, there’s the big money Chevron pumps into local elections to ensure none of this is examined too closely.




“The only time you ever saw Richmond on the news was two things: somebody’s bleeding or somebody’s burning,” Michele McGeoy, the founder of Solar Richmond, tells a class of job trainees at the beginning of the documentary “Catching the Sun.” “I want to create some good news in Richmond.”


The project in Richmond, and in cities like it across the country, is to shift from what environmental activist Van Jones, who also features prominently in the film, calls a “pollution-based economy,” filled with haves and have-nots, to an economy based on green energy — the environmental benefits of which are almost second to the creation of jobs, and the improved quality of life, that investment in solar innovation can create. The film follows the stories of the workers, entrepreneurs and political activists who are working to make that happen, and of the forces, both local and global, that can help or hinder the process.


Salon spoke with Shalini Kantayya, the film’s director, about America’s place in the global clean energy race. Our conversation has been lightly edited for length and clarity.


“Catching the Sun” starts out a little differently from most environmental films: You don’t really talk about the planet, large-scale, or climate change, but go straight to these very local impact of fossil fuels, focusing on one community where people might not normally prioritize environmental issues. Could you tell me a little bit more about why you chose that approach?


I was very interested in Richmond, California, as a symbol of other American cities. It was a large industrial city, and a lot of those industries have left Richmond, leaving it with high amounts of unemployment. Also, a lot of those industries had been dirty industries, so it had higher rates of cancer and asthma. When I discovered this Solar Richmond training program, I thought it could be a symbol of the type of transformation that could be good for cities across the country.


That’s sort of what put me on this journey, and I started to tell a small story about American workers seeking to retool for jobs in the solar industry. After a year or two of wondering why they haven’t gotten jobs, I started to unravel the large global forces at play deciding whether American workers get jobs in the industries of tomorrow. That journey took me to China. Integrating those two stories — that local story in Richmond and this global story in China — that took two years in the edit room.


It’s so disheartening in the second half of the film when this character who’s gone through the training program, and is now a skilled worker, just can’t find a job in solar. What are some of the global forces that you found that were working against him?


What I really began to understand in the making of this film is the importance of public policy in creating common good for us, as a democracy. I think we’ve been so swayed by media to believe that anything that is in the common good is communist. But actually our environment is something that is in our common good. And so, what I came to understand is that we can use the power of public policy to avert a crisis. Here in the United States we have a history of doing that — Ronald Reagan signed the Montreal Protocol. We know how to do that, and that’s what I got excited about in the making of this film. And the fact that, because we’re dealing with electricity, a lot of those decisions get made at the local and the state level, where people have a lot of power. With Congress totally missing in action, we can make this change all across the country.

Can you talk a little bit about how public policy toward renewable energy in the U.S. differs from what’s going on in China?


I think the foremost distinction is that the government of China accepts the signs of global warming and accepts the signs that human beings are causing it. And also, China has passed aggressive national policy to become a world leader in renewable energy technology. In two of its last five-year plans, it’s identified renewable energy as a major sector of growth in China. What we’ve seen with that very aggressive policy is, China went from producing a fraction of 1 percent of the world’s global solar to producing 90 percent of the world’s global solar. That happened essentially in just over five years. What’s interesting about China’s entry into renewable energy is that it’s also helped to bring the price down. What’s happening is that the U.S. now has the opportunity to create jobs downstream, in the installation, in the design and the engineering, where there are more jobs anyway — and those jobs cannot be outsourced. I really think the U.S. and China can work together to solve this crisis.


At the local level, you suggest the problem isn’t even about getting people to accept climate change. There’s that really strong moment in the beginning of the film where a couple is speaking at home. The husband says, “We can get solar panels on our roof. It can lower the electricity bill.” And the wife is telling him to “be practical” — she’s not believing it could happen. It seems like there’s still a lot of skepticism in the U.S. that this industry is capable of growing as much as it is projected to.


Absolutely, and here’s the thing: You don’t have to accept what 99 percent of the world’s scientists agree upon. You don’t have to actually believe in climate change to believe that solar energy is good for our country. I think that’s the big distinction that my film makes. It shows that in so many places across the country, it is the same cost or cheaper — rapidly becoming cheaper — than the cost of fossil fuels. And with fossil fuels, there are all these expenses that we don’t factor in to the cost of energy: say, for instance, pollution, and the effect that fossil fuels have on our air and the amount of asthma and the cost of sending our kids to the hospital for those inhalers. We don’t factor that into the cost of fossil fuels, nor do we factor the other costs that we spend: our human lives, our resources, our military. Once you begin to factor in those external costs, solar wins economically every day of the week and twice on Sunday.


I’m wondering, would you argue that taking climate change out of the renewable energy conversation altogether could be a way of depoliticizing it and moving forward?


Absolutely. I think one of the strongest things about the film is that we feature someone like Debbie Dooley, a Tea Party activist. Libertarians and Tea Party activists love solar because this is about a free market for energy, which we don’t have — we have a monopoly. Most of us get a bill from our utility company, and whatever they charge us, we have to pay. So there are lots of people on the left and on the right together who just want clean energy choices and consumer choices around energy. We want to break up these monopolies that we don’t need anymore around energy. We need to innovate around energy, and this is about being competitive in the technologies of the future.


When you think about something like solar, it’s renewable. Once you have it up, there’s no marginal cost. For so many places, it really makes sense. It is our job in the United States, as a government, to create the conditions to make us competitive in the next century, to make us competitive and innovative, which has always been the strength of the United States in the industries of tomorrow. Just like China, we should be doing this for national security reasons, we should be doing this for economic reasons and job reasons, and for the health of our communities.







What do we do about the opposition coming from utilities and from fossil fuel? The way the film treats Van Jones’ dismissal from the White House heavily implies that he was attacked by people who didn’t support the green energy agenda — how formidable of a threat do you see that as being?


Well, look. The fossil fuel industry consolidated wealth and power in the hands of very few people. That’s how we got the Koch brothers, that’s how we got the Saudi royal family, that’s how we got the 1 percent and so many problems of our democracy as a result of their wealth and power and influence and interference in our democratic process. I think the big exciting idea about solar energy is that it’s good for the 99 percent. When you have the right policy, like they did in Germany, you can put solar on your house, and you become an independent power generator. Instead of your utility sending you a bill, they’re sending you a check. You can imagine that the utility companies, they don’t want to do this! I mean industrialists were almost left out of the solar revolution in Germany: 80 percent of the people that benefited were ordinary citizens like you and me who became power generators. It’s good for our middle class, it democratizes energy, it decentralizes energy, it makes it more sacred. It has utility companies and 1-percenters who have benefited from dirty fossil fuels shaking in their boots, and with good reason. It’s economically competitive. I think we’re going to have a battle, and some of that is just around public education and making sure we get across the facts.


Are you optimistic that the U.S. will be able to build an economy like Germany’s — its own version of the clean energy economy?


In all honesty, my concern is that it will be big businesses that go solar. We’ll have big industrial solar, and it’ll be less every person becoming an independent power generator. But that really depends on the levers of public policy. Here’s what’s exciting: With Congress missing in action, at least 29 states have made commitments to being at least 10 percent renewable by 2020. States like California are leading the way — it’s already running on 25 percent renewable energy, and quickly moving to 33 percent. That’s happening on the state level. Here in Los Angeles, we’re moving to 20 percent by 2020, or making headway to set those targets.


I think this should be a race to the top. We should be outcompeting each other state by state to see who is going to be the most renewable state in the country. The more that we do that, and we get our mayors and our governors and our state representatives … and this isn’t the Congress! Your city council might have three friends from your high school on it that you know. We can make change at this level. This is tangible. But the democratization of our energy is going to require citizens to take action, that we go to our city councils and we go to our state leaders, and we say yes, we want clean energy choice. We want to be competitive in the industries of the future. We don’t want to miss the next opportunity, because the world already understands this. Most of the new energy that’s coming online in the world is already renewable. The world is going to be mostly renewable by 2030, so the only question is what country is going to get the biggest piece of that multi-trillion-dollar industry.


I really do believe that everything we love can be saved: our democracy, the middle class, the polar bears. But it’s going to be like a third industrial revolution. It’s going to take that kind of setting of targets and using the levers of public policy, which are the tools we have as a democracy.

As the pope opines on climate change, O'Malley releases a clean energy agenda

As some Catholic candidates seeking the Republican presidential nomination question the pope’s advocacy on climate change, Democratic hopeful Martin O’Malley is embracing it.


The former Maryland governor, who is a practicing Catholic, plans to issue a white paper Thursday morning that declares that the United States has a “moral obligation” to address climate change and outlines steps he would take to accelerate a move toward clean energy — including several that build upon Obama administration policies and some that depart from them.


The move from O’Malley comes as he tries to gain a foothold in a Democratic primary contest in which Hillary Rodham Clinton has established herself as a formidable front-runner and Sen. Bernie Sanders (I-Vt.) has been making more headway with more liberal voters.


[In Iowa, Sanders, O’Malley stake out liberal ground ahead of Clinton speech]


In his white paper, a copy of which was obtained by The Washington Post, O’Malley argues that a full embrace of clean energy presents the biggest job creation opportunity the country as seen in a century.


Among other initiatives, O’Malley will call for expanding an Obama administration effort to regulate emissions from power plants to include other sources of greenhouse gases, such as cement and fertilizer plans and existing oil and gas wells.


O’Malley, who pushed a series of renewable-energy initiatives as governor, also calls for a halt in issuing new oil and gas drilling permits in Alaska and off the U.S. coasts — a move that runs counter to recent Obama actions — and he says he would end all taxpayer subsidies for fossil fuels while extending production and investment tax credits for sources of renewable energy.


In the paper, O’Malley says he would direct the Environmental Protection Agency to adopt a “zero-tolerance” policy for methane leaks from oil and gas production and that he would reject projects like the proposed Keystone XL Pipeline that he says exacerbate climate change.The latter is a veiled jab at Clinton, who has not stated a definitive position on the project.


[Pope Francis blasts global warming deniers in leaked draft of encyclical]


O’Malley’s initiatives come as Pope Francis is expected to formally unveil on Thursday a highly anticipated and controversial papal encyclical on climate change. In recent days, several Catholic candidates in the Republican field, including former Florida governor Jeb Bush, have questioned the pope’s involvement on the issue.


O’Malley’s document references Republican resistance on the issue, saying he would push many of his actions through executive action, starting on “day one,” if elected president.


Some of those actions include retrofitting federal buildings to higher energy-efficiency standards and new requirements for the federal automobile fleet. O’Malley says he would also establish a “Clean Energy Job Corps” with the aim of retrofitting buildings and creating new green spaces across the country.


More broadly, he says in the plan, that he would set a goal to make the country completely powered by clean energy within 35 years.


During his tenure as Maryland governor, O’Malley muscled through legislation to jump-start the state’s offshore wind power industry, pushed several initiatives to expand the use of solar energy and signed legislation adopting tougher vehicle emissions standards.

By Obinna Chima with agency report


Quaint Solar Energy from Nigeria and Flatbush Solar from Cameroon will soon see their renewable energy projects fired up by a total of $5-million (R62 million) in new funding as well as expert technical support.
Access Infra Africa announced yesterday that the two firms shared first prize in the inaugural Access Co-Development Fund (ACF) competition.


According to African News Agency (ANA), Access, a developer, owner and operator of power assets in Africa, launched the competition in April in a bid to bridge the gap between early-stage African renewable energy projects and the expertise and funding they require to become operational.
Quaint Solar Energy’s winning Abiba solar project is a 50mw solar development that will utilise photovoltaic technology to help bridge the country’s power deficit. The Maroua solar project won by Flatbush Solar in Cameroon is a 20mw solar plant designed to serve the energy needs of the city of Maroua and neighbouring towns and villages.


The ACF had received 55 submissions from 18 African countries – including Kenya, South Africa, Morocco, Ghana, Rwanda and Tanzania – covering a range of technologies including solar, wind, hydro, hybrid and bio-mass.
The winning projects were selected by an expert panel after a live session at the Africa Energy Forum 2015 in Dubai at the end of last week. They were chosen based on commercial, technical and environmental merits, the local regulatory environment and the project team.


Other shortlisted projects included a 20MW photovoltaic plant by Ada Solar Energy in Ghana and a 10MW solar plant by Wagonanze Investments in Tanzania.
Director at Quaint Solar Energy, Seun Solesi said: “We are delighted to partner with Access Infra Africa to develop the Abiba solar project in Nigeria. Their funding, technical support and guidance will undoubtedly play a key role in bringing the project to fruition and creating significant benefit for all our stakeholders.”


Also, Managing Director of Flatbush Solar, Samuel Tesfaye said: “We are pleased that Access Infra Africa recognises the importance of providing funding and technical expertise to early-stage projects within the renewable energy sector in Africa.”
Similarly, the chairman of Access Power MEA, Reda El Chaar said: “It is a fantastic opportunity to be able to partner with two projects that will undoubtedly have a positive social and economic impact in their respective regions, and we look forward to working closely with them as they progress towards becoming operational.”


Access will take an equity stake in Flatbush Solar and Quaint Solar Energy and fund third-party development costs such as feasibility studies, grid studies, environmental and social impact assessments and other due diligence fees.

More Blues for the Greens


Now matter how many greenbacks the government throws at “green” energy, everyone ends up feeling blue. Yesterday the Wall Street Journal updated the story we’ve been covering for a long time now about the dismal performance of the Brightsource solar energy array in the California desert:


High Tech Solar Projects Fail to Deliver


$2.2 Billion California Project Generates 40% of Expected Electricity


By Cassandra Sweet


Some costly high-tech solar power projects aren’t living up to promises their backers made about how much electricity they could generate.


Solar-thermal technology, which uses mirrors to capture the sun’s rays, was once heralded as the advance that would overtake old fashioned solar panel farms. But a series of missteps and technical difficulties threatens to make newfangled solar-thermal technology obsolete.


The $2.2 billion Ivanpah solar power project in California’s Mojave Desert is supposed to be generating more than a million megawatt-hours of electricity each year. But 15 months after starting up, the plant is producing just 40% of that, according to data from the U.S. Energy Department. . .



It gets better:


One big miscalculation was that the power plant requires far more steam to run smoothly and efficiently than originally thought, according to a document filed with the California Energy Commission. Instead of ramping up the plant each day before sunrise by burning one hour’s worth of natural gas to generate steam, Ivanpah needs more than four times that much help from fossil fuels to get the plant humming every morning. Another unexpected problem: not enough sun. Weather predictions for the area underestimated the amount of cloud cover that has blanketed Ivanpah since it went into service in 2013.



Great: the place needs more water than thought. And California has lots of extra water lying around these days. And it takes fossil fuels to get the thing started up each day? I guess the carbon footprint of this plant is a little larger than advertised.


Oh, and speaking of heavy footprints, let’s not forget the wildlife mortality:


The Ivanpah plant was delayed several months and had millions of dollars in cost overruns because of wildlife protections for the endangered Desert Tortoise. Once built, U.S. government biologists found the plant’s superheated mirrors were killing birds. In April, biologists working for the state estimated that 3,500 birds died at Ivanpah in the span of a year, many of them burned alive while flying through a part of the solar installment where air temperatures can reach 1,000 degrees Fahrenheit.



What the heck, while we’re on the subject of epic-greenfail, let’s not overlook this recent story from the Washington Post:


How Europe’s Climate Policies Led to More U.S. Trees Being Cut Down


By Joby Warrick


OAK CITY, N.C. — For the sake of a greener Europe, thousands of American trees are falling each month in the forests outside this cotton-country town. . .


Soaring demand for this woody fuel has led to the construction of more than two dozen pellet factories in the Southeast in the past decade, along with special port facilities in Virginia and Georgia where mountains of pellets are loaded onto Europe-bound freighters. European officials promote the trade as part of the fight against climate change. Burning “biomass” from trees instead of coal, they say, means fewer greenhouse gases in the atmosphere.


But that claim is increasingly coming under challenge. A number of independent experts and scientific studies — including a new analysis released Tuesday — are casting doubt on a key argument used to justify the cutting of Southern forests to make fuel. In reality, these scientists say, Europe’s appetite for wood pellets could lead to more carbon pollution for decades to come, while also putting some of the East Coast’s most productive wildlife habitats at risk.



Time to cue one of Jon Stewart’s greatest takedowns on how our “energy-independent future” is powered by fossil fuels. (Worth waiting through the ad: I show this to students, and it saves a lot of time reviewing the four-decade folly of what we’ve called “energy policy.”)


Not to worry. I’m sure poop-powered vehicles are just around the corner. Oh, wait—you’re kidding me!

Your workplace may have toxic air

The workplace is causing you harm that is more than just stress-related. A new study found an excessive amount of chemical emissions called toxic total volatile organic compounds (TVOCs) in air-conditioned offices. Prolonged exposure to these emissions could lead to health problems, including eye, nose, and throat irritation, headaches and damage to the liver, kidney and the central nervous system. Some VOCs can cause cancer.


The National Environmental Engineering Research Institute (NEERI), Worli, and Rachana Sansad’s Institute of Environmental Architecture (RSIEA), Prabhadevi, came to this conclusion after studying four office spaces in the city.


A five-member team found TVOCs such as benzene, toluene, xylene and formaldehyde emitted from furniture material, paints and furnishings. Major components of indoor air, TVOCs contain carbon that easily evaporates from the products into the air at room temperature.


While India has no permissible standards for TVOCs, the team found that on an hourly basis, carpet tiles emitted the most TVOCs at 3,320 microgram a cubic metre (µg/m3), followed by painted surfaces at 2,430 µg/m3 and modular furniture at 2,410 µg/m3. Gypsum ceilings emitted the lowest TVOCs at 200 µg/m3. Furniture that emits TVOCs from laminates and fabric contributes to 21% of the emissions. The European Union has set the permissible limit of TVOCs at 300ug/m3 with no single compound contributing more than 10% of the total.


Previous studies have found the level of TVOCs indoors to be 10 times more than the outdoors. “TVOC is one of the precursors for ground-level ozone, which is toxic in nature. Since the concentration of TVOCs is so high, indirect sunlight coming into the office will lead to the production of ozone, which may cross the permissible limit of 100ug/m3, leading to respiratory illnesses,” said Gufran Beig, scientist, Indian Institute of Tropical Meteorology, Pune.


“Indoor air pollution is a rising concern in an office environment because employees spend their time working in closed offices. Most of their daily exposure to many pollutants comes through the intake of indoor air, deteriorating the air quality,” said Satinder Kaur, research scholar, NEERI.


Kaur said, “TVOCs also adhere or get adsorbed to fine particulate matter and persist for a longer period. The persistence of TVOCs can be felt in many workplaces, where ventilation is poor or the HVAC (heating, ventilation and air conditioning) system is not designed appropriately.”


For the study, air-conditioned offices spread over an area of 4,000 sqft with 100 workstations were selected. Two-year-old modular furniture was used for sampling, and surface areas of office indoor components such as ceiling, flooring, furniture and partitions were measured.


To ensure there is no influence of outdoor contaminants, researchers set up an experimental clean room chamber and sanitised the space to ensure TVOC emissions were below baseline levels. Following this, gypsum tiles, furniture that included workstations, carpet tiles and painted surfaces were introduced. The quantity of materials introduced into the clean room was based on the percentage of surface areas obtained from the survey of the selected four offices. Readings of VOCs after interior material was introduced showed a significant increase in four hours. Data was collected between 11am and 3pm for four days, and the chamber was thoroughly ventilated for 10 to 12 hours before every sampling.


“TVOCs get accumulated in offices and therefore material containing TVOCs must be avoided when setting up infrastructure. In addition, ventilation must be allowed in offices twice a day if it is possible to open doors and windows, centralised air conditioners should meet the required standards or workplaces must introduce high-end air filters that can absorb TVOCs,” said Roshni Udyavar Yehuda, head, RSIEA.

Intersolar Award: And the winner is ...

At the start of the Intersolar Europe, particularly innovative solutions in the areas ‘Photovoltaics’ and ‘Solar Projects in Europe’ received the Intersolar Award. The prize was awarded for the eighth time as part of an official ceremony at the trade fair’s Innovation Exchange.


The exhibiting companies at all Intersolar trade fairs worldwide were called upon to demonstrate their outstanding innovations to the jury. In order to be eligible to apply, the submitted products, projects, services and solutions had to be in the testing phase or already in the field. In addition, it either had to be the first time they were displayed at the Intersolar or they had to be significant further developments of existing products. On top of that, the solar projects had to have been fully implemented during the last two years. The evaluation criteria were based on existing challenges on the market. The areas evaluated included the level of technological innovation, benefit for industry, environment and society, economic efficiency, and proof of innovation.


The relatively new Californian manufacturer HiQ Solar won an Intersolar Award in the ‘PV’ category for its three-phase inverter TrueString 480V, LG Electronics Deutschland GmbH won it for the PV module MonoX NeON 2 and REC Solar EMEA GmbH received the award for its TwinPeak module. The winners in the category ‘Solar Projects in Europe’ are IBC Solar AG for its project ‘EnFa – The Energy Factory’, solarnova Deutschland GmbH for its ‘Aktiv-Stadthaus’ in the Gutleutviertel district of Frankfurt and Ritter Energie- und Umwelttechnik GmbH & Co. KG together with Ritter XL Solar GmbH, the Fraunhofer Institute UMSICHT, GEA Wiegand GmbH and the University of Karlsruhe, which jointly implemented a project for solar air conditioning in buildings.


Lightweight and durable: An inverter for industrial rooftop installations


The three-phase inverter TrueString 480V from HiQ Solar was designed primarily for industrial rooftop systems. It is equipped with two independent 1000-V DC inputs with individual MPP tracking. Cutting-edge semiconductor technology based on silicon carbide gives it a CEC efficiency rating (in accordance with the California Energy Commission) of 98% as well as a high power density. The device only weighs 11 kg and is so robust that it can even be used in extreme desert and coastal conditions.


Cleverly wired: CELLO makes for a more sustainable module


LG Electronics was able to increase the efficiency of the MonoX NeON 2 module while reducing the amount of materials used to manufacture it, allowing the module to be produced and sold at a cheaper price in the future. Its CELLO technology uses twelve wires to make contact with the front side of the cells. The wires reflect the incoming light, thereby optimising solar power generation. “This solution puts LG at the forefront of a technology that is currently being discussed by many people and will likely be used increasingly in the future,” the jury said.


First cut in half, then soldered back together: a useful innovation in module technology


To manufacture its TwinPeak module, REC Solar first cuts the PERC (Passivated Emitter Rear Cell) cells in half and then solders them together again, creating a low-loss electrical connection. In addition, four busbars make the electrical connection to the cells instead the three that were used previously. Also, two separate junction boxes are connected to each terminal pole. Thanks to this electrical connection concept, the TwinPeak modules have an output 10 W higher than standard modules.


Brave pioneering: decentralised supply using renewable energy is possible


‘EnFa – The Energy Factory’ from IBC Solar is a further step towards off-grid operation of commercial enterprises. The building, which was constructed in Neuenstadt am Kocher in 2014, generates all of the energy it needs for heating, cooling, e-mobility and electricity requirements itself. Biogas is used to cover its energy requirements during months when the yield is low. This is made possible by a smart energy management system that integrates the photovoltaics, power storage, combined heating and power plant as well as heat pumps. EnFa is proof that it is possible to implement a decentralised energy supply in Germany that is based purely on renewable sources, is uninterrupted, provides a stable local grid, and has low costs.


Everything planned for: block of flats in Frankfurt produces an energy surplus


The ‘Aktiv-Stadthaus’, which solarnova participated in building, generates more energy than the residents of the 75 flats consume. Passive efficiency through insulation as well as active energy generation are perfectly combined in this ‘Efficiency House Plus’. The most innovative part of this concept is that the energy requirements of the users as well as urban planning integration were taken into consideration during the design phase. “The Aktiv-Stadthaus clearly demonstrates that the EU’s Energy Efficiency Directive for the year 2020 can be achieved,” the jury said of their reasons for giving the project the Intersolar Award.


Strong partners: consortium combines various new developments


The joint project for solar air conditioning in buildings, which uses a solar collector array with plasma technology to generate steam, convinced the jury. Its key component is a high-efficiency vacuum tube collector. Thanks to its special anti-reflective coating, the collector can even achieve a remarkable level of efficiency at temperatures between 100 and 150 ° C. In addition, a steam jet ejector chiller with a cooling capacity of 80 kW that was designed specifically for the project is installed. The solution is complemented by a specially developed heating and cooling storage system, which provides largely consistent operating conditions. The solar thermal system impressively demonstrates that it is possible to provide effective, economical and environmentally friendly air conditioning using solar energy, even with German weather conditions.
