2013 to be Record Year for Offshore Wind

Offshore wind power installations are on track to hit a seventh consecutive annual record in 2013. Developers added 1,080 megawatts of generating capacity in the first half of the year, expanding the world total by 20 percent in just six months.

Fifteen countries host some 6,500 megawatts of offshore wind capacity. Before the year is out, the world total should exceed 7,100 megawatts. Although still small compared with the roughly 300,000 megawatts of land-based wind power, offshore capacity is growing at close to 40 percent a year.

In 1991, Denmark installed the world’s first offshore wind farm, a 5-megawatt project in the Baltic Sea. The country’s offshore wind sector has since alternated between lulls and bursts of activity. Since 2008, Denmark’s offshore wind capacity has more than tripled, topping 1,200 megawatts by mid-2013. Over 350 megawatts of offshore wind power were plugged into the grid in the first half of the year—all of it to complete the 400-megawatt Anholt project, which is expected to meet 4 percent of Danish electricity needs.

Denmark already gets more than 30 percent of its electricity from wind—onshore and offshore—and aims to increase that share to 50 percent by 2020. At about one third the size of New York State, Denmark has the world’s highest wind power capacity per square mile, so it will rely mostly on offshore expansion to hit the 2020 target.

Denmark was first to put wind turbines in the sea, but today it ranks a distant second to the United Kingdom in total offshore wind generating capacity. More than 500 megawatts of new offshore wind power went online in U.K. waters in the first half of 2013, bringing the country’s grand total to over 3,400 megawatts—enough to power more than 2 million U.K. homes.

The bulk of this new offshore capacity went to completing the 630-megawatt first phase of the London Array, now the world’s largest offshore wind farm. It overtook another U.K. project, the 500-megawatt Greater Gabbard wind farm, which was finished in 2012. In all, the United Kingdom has some 12,000 megawatts of offshore wind capacity under construction or in earlier development stages.

Belgium’s offshore wind capacity grew 20 percent to 450 megawatts in the first half of 2013, placing it third in the world rankings. Germany reached 380 megawatts of offshore wind and will have at least 520 megawatts by year’s end. Beyond this, the German offshore industry expects another 1,000 megawatts will connect to the grid in both 2014 and 2015.

Countries in Asia are starting to make offshore wind power more than just a European affair. China, for example, brought its first offshore wind farm online in 2010. Since then, China has quickly climbed to fourth in the world, with 390 megawatts. The official goal is for 5,000 megawatts of wind capacity in Chinese waters by 2015, ballooning to 30,000 megawatts by 2020.

In Japan, where land is at a premium and where the future of nuclear energy is in question, offshore wind is gaining attention as a potentially huge domestic, carbon-free power source. A 16-megawatt project inaugurated in the first half of 2013 bumped Japan’s offshore wind capacity to 41 megawatts.

Because Japan lacks much shallow seabed in which to fix standard offshore turbines, new floating turbine technology is likely the future for offshore wind there. Off the coast of Fukushima prefecture, a 2-megawatt floating turbine will begin generating electricity in November 2013, the first stage of a 16-megawatt demonstration project. If it performs well, the hope is to expand the project’s capacity to up to 1,000 megawatts by 2020.

Floating turbines may actually be a big part of future offshore wind development at the global level. Not only do they greatly expand the area available for wind farms, they also have the potential to dramatically reduce the cost of offshore wind generation, which today is more than twice as expensive as that from turbines on land. While offshore wind manufacturers have managed to achieve cost reductions for the turbines themselves—through lighter, stronger materials and increased efficiency, for example—these savings have thus far been offset by the rising cost of installing and maintaining turbines fixed to the seabed as projects move into deeper waters.

The renewable energy consultancy GL Garrad Hassan notes that working around harsh weather becomes much easier with floating turbines: when conditions are favorable, relatively cheap tugboats can bring a turbine to the project site for quick installation, avoiding the need for specialized installation vessels. The turbine can be floated back to shore when the time comes for maintenance, lowering both cost and risk.

The world is gaining experience in using this young technology. In the last few years, Norway’s Statoil and Seattle-based Principle Power have both deployed floating wind prototypes successfully, in Norwegian and Portuguese waters, respectively.

In June 2013, the United States at last joined the offshore wind club when a 20-kilowatt (0.02-megawatt) floating wind turbine anchored off the coast of Maine first sent electricity to the state’s power grid. The turbine developer, DeepCwind, a consortium led by the University of Maine, plans to deploy two much larger versions, 6 megawatts each, in 2016.

The first full-fledged offshore wind farm in the United States, though, will likely be of the traditional variety fixed to a foundation in the seabed. Three proposals—Massachusetts’ 470-megawatt Cape Wind project, Rhode Island’s 30-megawatt Block Island Wind Farm, and New Jersey’s 25-megawatt Fisherman’s Energy I project—are the closest to beginning construction.

U.S. offshore wind’s potential is staggering. According to the U.S. Department of Energy, shallow waters along the eastern seaboard could host 530,000 megawatts of wind power, capable of covering more than 40 percent of current U.S. electricity generation. Adding in deeper waters and the other U.S. coastal regions boosts the potential to more than 4.1 million megawatts.

This is consistent with the findings of a 2009 Harvard study that calculated wind energy potential worldwide. The authors estimated that in most of the world’s leading carbon dioxide-emitting countries, available wind resources could easily meet national electricity needs. In fact, offshore wind alone would be sufficient.

Clearly, the world has barely begun to realize its offshore potential. Indeed, in some countries, regulatory and policy uncertainty seem to be sapping offshore wind’s momentum just as it really gets going, clouding the picture for future development. The U.K. government, concerned about costs, recently changed its target date for 18,000 megawatts of offshore wind from 2020 to 2030. In Germany, turbine orders are scarce as developers await the new coalition government’s plans for regulations and incentives. And in China, offshore wind companies say the guaranteed price for the electricity they generate is set too low to stimulate rapid growth, calling into question whether the country can hit its ambitious goals for 2015 and 2020.

Reflecting the hazy outlook in these and other key countries, projections for global offshore wind capacity over the next decade or so—from research and consulting firms and from industry publications—range anywhere from 37,000 to 130,000 megawatts. Despite the impressive growth of recent years, it seems that the lower end of these forecasts is much more likely. We know there is practically no limit to the available resource. What remains to be seen is how quickly the world will harness it and give offshore wind power a more prominent place in the new energy economy.

Long, cold winter for 3 million who can’t pay their energy bills

Three million elderly people fear they will not be able to stay warm in their own homes this winter, following the recent steep increases in the cost of heating, according to research published today.

The plight of many older householders emerged as the Government faced renewed calls to offer immediate help to lower-income families struggling to pay energy bills. Four of the “Big Six” energy companies have raised their prices before the winter surge in demand, with the average combined electricity and gas bill now standing at £1,267 per year.

Executives from the firms, which have been accused of acting as a cartel, will appear before MPs tomorrow to defend the sharp rises. Yesterday their trade organisation dismissed calls for a windfall tax on the Big Six, insisting their profits were not “particularly big”.

Over the weekend it also emerged that energy companies have been using tax loopholes. Although he declined to comment on individual companies, Danny Alexander, the Chief Secretary to the Treasury, said yesterday: “People are rightly livid about companies and individuals avoiding paying the proper amount of tax. I’m livid about that. It is something which is not acceptable at any time, but particularly at a time when we’re going through tough spending choices.”

He was speaking after The Independent on Sunday reported that three companies – Scotia Gas, UK Power Networks and Electricity Northwest – had saved £140m between them by using legal tax loopholes to minimise their liabilities. With gas and electricity prices continuing to dominate exchanges between political leaders, a survey for Age UK found that 28 per cent of pensioners said their main concern for the coming cold months was ensuring they could heat their homes. The charity said the figures suggested the problems could affect as many as three million older people across the UK.

Age UK also raised the alarm over the health dangers to the elderly people, warning that cold weather and poorly heated homes increased the risk not only of influenza but also of heart attack and stroke. There are about 24,000 excess deaths in a typical British winter, many of them preventable.

Age UK said more than 40 per cent were caused by heart attack or stroke. Caroline Abrahams, the charity’s director, said: “It’s vital for older people to keep warm, both inside and outside their homes in the winter months. Being cold, even for just a short amount of time, can be very dangerous, as it increases the risk of associated health problems and preventable deaths during the winter.”

Senior executives from the Big Six will be challenged to justify the recent price hikes when they appear before the Commons Energy and Climate Change Select Committee. Simon Hughes, the Deputy Liberal Democrat leader, said Chancellor George Osborne should use the Autumn Statement in December to announce emergency help for families struggling with bills.

“I would like people to have a rebate on energy bills that would help the poorest most and would mean that there would be immediate relief this year, not waiting for the post-election period,” he told BBC1’s Sunday Politics.

Ed Miliband, the Labour leader, has said an incoming Labour government would force energy firms to freeze their prices for 19 months, while the former Tory Prime Minister Sir John Major has called for a levy on their profits.

But Angela Knight, chief executive of Energy UK, which represents the companies, said their profits were not large enough to justify a windfall tax. “The profits here are, what, four to five per cent, four or five pence in the pound. That isn’t particularly big,” she said. She added that the companies were also making large investments in the UK and therefore had to have an “operating margin”.

The Government has invested an extra £500m in A&E services in a bid to avoid another winter crisis on emergency wards. A&E units have been under increased pressure for several months. MPs warned in the summer that the system may struggle to cope in the event of a major winter flu pandemic.

Dr Paul Cosford, director for health protection and medical director at Public Health England (PHE), said: “In colder weather, keeping yourself warm is essential to staying healthy, especially for the very young, older people or those with a chronic condition such as heart disease and asthma. There are a range of health problems associated with cold housing and winter weather, but, in particular, a cold indoor or outdoor environment can make heart and respiratory problems worse and can be fatal.”

PHE said living-room temperatures should ideally be kept at 70F (21C) and above, whereas bedroom temperatures should be kept at a minimum of 64F (18C).

Health leaders have also urged all at-risk groups – including the over-65s – to have a flu vaccination.

PHE will work with the Met Office between 1 November and 31 March 2014. Low temperatures of 2C or less or a spell of heavy snow will trigger cold weather alerts, which require hospitals, social care systems and GP surgeries to ensure they are prepared for spikes in demand. More

Dragonfly Inspired Wind Turbine

The architect Renzo Piano and an energy company in Italy, they are proposing a relative small wind turbine, suitable for the average yard. They describe it as being based on the physics of dragonfly flight.

Tests have already begun on the wind turbine, designed by the architect Renzo Piano in partnership with ENEL green power, an Italian multinational renewable energy corporation.

“The new wind turbine which is sensitive to the low-altitude diffuse wind more common in Italy, has produced over 1,200 KWh in two months of testing at the Molinetto test field, in the Province of Pisa.

The new slim-line, two-blade turbine is less visible than the traditional three-blade design, to the extent that it is difficult to detect in the landscape, but it has also shown itself to be capable of functioning also with low-intensity wind.

This result has also been made possible by the research into new, ever lighter and more resistant materials and by the new technology solutions employed in the construction of the turbine.”

ADB Releases Report on Managing the Water-Food-Energy Nexus


September 2013: The Asian Development Bank (ADB) has released a report, titled 'Thinking About Water Differently: Managing the Water-Food-Energy Nexus,' which argues for recognition of water as an economic and social good and the urgent assurance of regional water security to eliminate risk to food and energy security in Asia and the Pacific.


According to the ADB report, which offers high-level guidance on water issues affecting the region, governments need to think differently about water, taking a longer-term view of the limited resource. It highlights the importance of the following strategic approaches: reforming water governance through advocacy at global, regional, and national levels; generating reliable data and information on the availability and behavior of water resources; resource protection through effective reduction of wastewater and other waste discharging into freshwater supplies through regulation, investment, and innovation; water for food through stimulating research into improving the use of water in agriculture, increasing food production on the same area of land, and using less water; and increasing storage including via aquifer recharge, as a response to uncertainties in supply that are being aggravated by climate change.

Meet the newest big solar developers: Native Americans

The world’s largest solar thermal power plant plugged into the California grid this week, the first of what was supposed to be a dozen big solar projects to be built in the desert southwest of the US. It also may be one of the last for a while.

Ivanpah Solar Thermal Plant

When regulators licensed BrightSource Energy’s $2 billion, 377-megawatt (MW) Ivanpah Solar Electric Generating System in 2009, it was the first such solar thermal project to get the green light in California in nearly three decades. Unlike photovoltaic panels that directly convert sunlight into electricity, solar thermal power plants deploy tens of thousands of mirrors called heliostats that focus sunlight on liquid-filled boilers to create steam. The steam drives a conventional turbine to generate electricity. Solar thermal plants are far more efficient than solar panels and offer a more dependable source of power.

But as we’ve written before, many of those projects faltered in the face of environmental opposition—they displace the imperiled desert tortoise, among other critters—and competition from ever-cheaper photovoltaic projects that can be built close to cities without the need to construct multi billion-dollar transmission lines. Even big photovoltaic desert projects, which tend to be lighter on the land, have run into fierce fights.

There is, however, one place where Big Solar remains big business: Native American lands. Today, First Solar, the giant solar panel maker and developer, announced that it had acquired a 250-megawatt photovoltaic farm to be built on the tribal lands of the Moapa Band of Paiutes Indians near Las Vegas. The project was initially developed by a New York firm called K Road Power and will sell the electricity it generates to the Los Angeles Department of Water and Power under a 25-year contract.

The Moapa Solar Project is part of a massive 1,500 MW of renewable energy the tribe plans to develop, including other solar power plants. Native American projects are doubly attractive to developers like First Solar. As sovereign nations, the tribes exercise control over their lands and offer fewer avenues for opponents to use environmental laws to slow or derail projects.

First Solar representatives did not respond to requests for comment, and it’s unclear whether the Arizona company will ultimately retain ownership of the power plant. It usually develops projects and then sells them to investors or power plant operators. The Moapa sales price was not disclosed but in this case it’s essentially buying the work K Road did in getting the project approved. First Solar will design the power plant, which will produce enough electricity to power 100,000 homes, and build it with its own thin-film photovoltaic panels.

Construction is set to begin by later this year and the solar farm is expected to go online by the end of 2015. The far more technologically complex Ivanpah project, in contrast, has been under construction for four years. Some 170,000 heliostats are arrayed around three 459-foot “power towers” topped with water-filled boilers. This week engineers successfully connected the first of Ivanpah’s three phases to the grid in a test of its ability to deliver electricity to utility Pacific Gas & Electric. More

New Report First to Quantify Damage Done by Gas Drilling

“The numbers don't lie — fracking has taken a dirty and destructive toll on our environment. If this dirty drilling continues unchecked, these numbers will only get worse,” said John Rumpler, senior attorney for Environment America.

“At health clinics, we’re seeing nearby residents experiencing nausea, headaches and other symptoms linked to fracking pollution,” said David Brown, a toxicologist who has reviewed health data from Pennsylvania. “With billions of gallons of toxic waste coming each year, we’re just seeing the ‘tip of the iceberg’ in terms of health risks.”

The “Fracking by the Numbers” report measured key indicators of fracking threats across the country, including:

• 280 billion gallons of toxic wastewater generated in 2012,
• 450,000 tons of air pollution produced in one year,
• 250 billion gallons of fresh water used since 2005,
• 360,000 acres of land degraded since 2005,
• 100 million metric tons of global warming pollution since 2005.

Fracking also inflicts other damage not quantified in the report — ranging from contamination of residential wells to ruined roads to earthquakes at disposal sites.
Reviewing the totality of this fracking damage, the report’s authors conclude:

Given the scale and severity of fracking’s myriad impacts, constructing a regulatory regime sufficient to protect the environment and public health from dirty drilling — much less enforcing such safeguards at more than 80,000 wells, plus processing and waste disposal sites across the country — seems implausible. In states where fracking is already underway, an immediate moratorium is in order. In all other states, banning fracking is the prudent and necessary course to protect the environment and public health.

At the federal level, the report’s data on land destroyed by fracking operations comes as the Obama administration considers a rule for fracking on public lands, and as the oil and gas industry is seeking to expand fracking to several places which help provide drinking water for millions of Americans — including the White River National Forest in Colorado and the Delaware River basin, which provides drinking water for more than 15 million Americans.

Along with the new numbers in today’s report, Environment America’s John Rumpler added one more: the more than 1 million public comments submitted this summer to the Obama administration rejecting its proposed rule for fracking on public lands as far too weak. Environment America is urging President Obama to follow the recommendation of his administration’s advisory panel on fracking to keep sensitive areas as off-limits to fracking.

“We need decisive action from Washington to protect our communities,” said John Fenton, a rancher from Pavillion, Wyoming who last week appealed to federal officials to re-open an investigation into contamination of drinking water there.

“The bottom line is this: The numbers on fracking add up to an environmental nightmare,” said Rumpler. “For our environment and for public health, we need to put a stop to fracking.”
Of particular concern are the billions of gallons of toxic waste created from fracking, which threaten the environment, public health and drinking water. Environment America is calling on federal officials to close the loophole that exempts this waste from our nation’s hazardous waste law. Rep. Matt Cartwright (PA-17) has introduced the CLEANER Act, H.R. 2825, to close that loophole.

“The data from today’s report shows that fracking is taking a dirty and destructive toll on our environment and health,” said Rumpler. “It’s time for our federal officials to step up; they can start by keeping fracking out of our forests and away from our parks, and closing the loophole exempting toxic fracking waste from our nation’s hazardous waste law.” More
