Household Solar Panel
Installations up 52 Percent in the U.S.
Household solar power is on the rise throughout the U.S., a new report shows
, with installations in the third quarter of 2013 up 52 percent over the same period last year. Those installations generate a total of 930 megawatts of power, a 35 percent increase over third quarter 2012. The U.S. has likely surpassed Germany to
become the world's leader in solar power generation, the report from GTM Research and the Solar Energy Industries Association says. California leads the country in the number of installations, followed by Arizona and North Carolina. Residential solar power is still a small slice of the total solar power market, but it's showing the strongest growth as household solar installation costs fell 9.7 percent over the past year. Of those costs, hardware expenses, including solar panels and transmission equipment, are steadily shrinking. But so-called "soft costs," such as financing and labor, now account for 64 percent of the price of household solar power installations, according to new research from the National Renewable Energy Laboratory

Final Shipment of Russian
Warhead Uranium Set to Reach U.S. Today
A U.S. nuclear storage facility today will receive the final shipment of decommissioned nuclear warheads from Russia, NPR reports
. Since 1993 the Russian uranium has been generating 10 percent of all electricity consumed in the U.S., part of a deal struck with the former Soviet state when its nuclear industry, crippled by arms reduction agreements, was struggling to make
Russian uranium ready for shipment to U.S.
ends meet. Negotiations began when a U.S. official visited Russia in the early 1990s and found bomb-grade uranium from thousands of decommissioned warheads lying around in crumbling storage facilities. Concerned that the radioactive material was unsecured and vulnerable to theft, the U.S. asked to buy it. Russian officials reluctantly agreed to convert roughly 500 tons of bomb-grade uranium into nuclear fuel and sell it to the U.S. Experts say it was a win-win scenario: Russia made a substantial profit ($17 billion), U.S. power plants could buy the uranium at a good price, and 20,000 bombs' worth of radioactive material was converted into relatively clean electricity. The deal will go down in history as one of the greatest diplomatic achievements ever, one expert told NPR.

China Doubles Pace
Of Renewable Energy Installation in 2013
Over the past 10 months China has added renewable energy sources to its power grid at double the pace of 2012, according to its National Energy Administration (NEA). The renewable energy push, part of a massive effort to cut air pollution in China's large cities, has added more than 36 gigawatts of clean energy capacity
Shanghai, Dec. 3, 2013
so far this year, Bloomberg News reports
. Hydroelectric power grew by 22.3 gigawatts in the first 10 months of 2013, new nuclear energy installations totaled 2.2 gigawatts, solar 3.6 gigawatts, wind 7.9 gigawatts. China's solar energy capacity could triple from 2012 levels to 10 gigawatts by the end of the year, while wind and nuclear power capacity could increase by 22 and 17 percent, respectively, the NEA said. That should offer some relief from China's choking air pollution. In Shanghai, schoolchildren were ordered indoors today
as air pollution reached extremely hazardous levels, exceeding World Health Organization health guidelines for fine particulate matter by 24 times.

Urban Car Use Declines
As Biking and Public Transit Rise in the U.S.
Americans in urban areas are driving less, biking more, owning fewer cars, and using public transportation more frequently, according to new research by the U.S. Public Interest Research Group
(U.S. PIRG). The number of people driving to work fell in 99 of 100 major urban areas between 2006 and 2011, and the number of miles driven by car fell in three-quarters of the cities studied over that time, the PIRG study showed. The proportion of people biking to work increased in 85 of 100 cities, while the number of miles traveled on public transit increased in 60 of 98 cities. Meanwhile, the number of people working from home grew in all 100 cities, the report said. From 2004 to 2012, the average number of vehicle-miles driven per person decreased by 7.6 percent nationwide. "There is a shift away from driving,” said Phineas Baxandall, an analyst for the U.S. PIRG Education Fund. "Instead of expanding new highways, our government leaders should focus on investing in public transit and biking for the future."

New Paper Offers Sweeping
Plan to Decarbonize the Global Economy
Eighteen prominent international climate scientists and economists have authored a paper
that seeks to answer the most vexing environmental question facing the planet: How to reverse soaring carbon dioxide emissions and prevent the world from experiencing destabilizing climate change. Their answer, presented in the journal PLOS One,
boils down to this: Offer global leaders a detailed blueprint for decarbonization that involves setting a steadily rising price on carbon, the large-scale deployment of nuclear power and renewable energy, increased research into low-carbon energy technologies, and a reform of forestry and agricultural policies that leads to massive sequestration of CO2 — all while not spending more than 1 percent of global gross economic output. “In terms of economics, comparing a path to decarbonization versus a path of wrecking the planet are not even close,” economist Jeffrey Sachs, a co-author of the paper and director of Columbia University’s Earth Institute, said at a press briefing. “We haven’t shown the path of decarbonzation clearly enough (and) what the real choices are.”

Majority of Americans
Uninformed About Fracking, Survey Finds
Most Americans are uninformed and lack opinions on hydraulic fracturing, or fracking, a process used to extract oil and gas from rock formations, a new survey says
. Fifty-eight percent of people surveyed specifically reported that they knew nothing at all about fracking, and the same percentage said they didn't know whether they supported fracking or opposed it. Seven percent said they were aware of some of the process's environmental impacts, and 3 percent said they knew of positive economic and energy supply impacts of fracking. Of those who held an opinion on it, 20 percent were opposed to fracking and 22 percent supported it. "Broadly speaking, our results paint a picture of an American populace that is largely unaware and undecided about this issue," the study says. The study
— conducted by researchers at Oregon State, George Mason, and Yale universities — was recently published in the journal Energy Policy

U.K. Government Pledges
To Stop Backing Foreign Coal Power Plants
The United Kingdom has joined the U.S. in pledging
to stop using government funds to finance coal-fired power plants in other countries. "The two governments are going to work together to secure the support of other countries ... and the multilateral development banks to adopt similar policies," Britain's energy secretary told journalists gathered in Warsaw at the U.N. climate talks. The U.S. made the same pledge last month in an attempt to slow CO2 emissions from the world's coal-fired power plants. The International Energy Agency reports that coal accounted for 44 percent of global carbon emissions in 2011, and the fossil fuel remains the world's largest source of electricity and heat. While many diplomats applaud the U.K.'s move, U.N. Secretary General Ban Ki-moon and environmental groups are pushing for even stronger action, including more spending on renewable energy. "The rapid development of low-carbon infrastructure needs large injections of public capital," Ki-moon said.

Low-Income Solar Project
Is Recognized at U.N. Climate Talks
An Australia-based solar start-up company was recognized at the U.N. climate change talks in Warsaw for its work replacing highly polluting kerosene lamps with solar lighting in low-income regions of India. The company, Pollinate Energy, trains members of local communities to install household solar-powered lights in India's slums, where families often rely on kerosene for lighting. So far the project has installed solar-powered lighting systems for 10,000 people in 250 of Bangalore’s slum communities, in turn saving 40,000 liters of kerosene and 100,000 kilograms of carbon emissions, RenewEconomy reports
. The solar lighting systems are cheaper to operate than kerosene lamps and are less polluting and dangerous than kerosene, which can cause house fires and severe burns. The nonprofit project started in Bangalore — home to some of India's worst slums — as a way for children to do schoolwork after sunset. Pollinate Energy trains local installers to distribute and install the lighting systems as micro-entrepreneurs, which they call "pollinators."

U.N. Climate Chief Says
Many Coal Reserves Must Be Left in Ground
United Nations climate chief Christiana Figueres said that coal power can be part of the solution to curbing global warming, but it would require shuttering older coal power plants, advancing carbon capture and storage (CCS) technology, and resolving to leave much of the planet's existing coal reserves in the ground. Her remarks, given at the International Coal and Climate Summit in Warsaw, are drawing criticism from environmentalists who oppose continued reliance on coal power. John Gummer, the chair of the U.K.'s climate advisers and former U.K. environment minister, told the Guardian
that "calling coal a clean solution is like characterizing sex trafficking as marriage guidance." Figueres said that coal power holds promise as a means of helping poorer countries develop their economies and reduce poverty, but said that the industry "must change." Figueres joins the growing list
of climate leaders who say that more than half of remaining fossil fuel reserves must be left in the ground
in order to avoid massive carbon emissions that could destabilize the climate.

China's Renewable Power
Sector Set to Outpace Rest of World by 2035
China is on track to generate more electricity from renewable energy by 2035 than the U.S., the European Union, and Japan combined, the International Energy Agency (IEA) said in a new report
. In its World Energy Outlook report, the IEA also said that by 2035 renewable energy sources — wind, solar, hydropower, and biomass — will make up more than 30 percent of the world's electricity supply, surpassing natural gas and rivaling coal as the leading energy source. Wind and solar photovoltaic power will see especially large gains, helping renewable energy account for nearly half the increase in global power generation over the next two decades, the IEA said. Carbon emissions related to energy generation will likely rise by 20 percent over that time, the report said, but policies and initiatives in the U.S., China, Europe, and Japan may help limit those emissions. "The right combination of policies and technologies is proving that the links between economic growth, energy demand and energy-related carbon dioxide emissions can be weakened," the IEA said.

Smaller Rise in Global CO2
Emissions May Be Sign of Permanent Slowing
Global carbon dioxide emissions grew last year at about half the rate of the past decade, possibly signaling a permanent slowdown of CO2 emissions, says a new report
from the Netherlands Environment Assessment Agency and the European Commission's Joint Research Center. Although total CO2 emissions reached a record 34.5 billion tons, the increase over 2011 was only 1.1 percent — less than half the average rate of increase over the past decade. China, the U.S., and the European Union accounted for 55 percent of global CO2 emissions. China, which emitted 29 percent of total CO2, increased its rate by only 3 percent, a significant slowdown from its average recent growth of 10 percent. The analysts credit the slowdown to China's rapid growth in hydropower
. The U.S. and European Union saw their emissions fall by 4 percent and 1.6 percent, respectively. The report links those declines to increased shale gas use in the U.S. and decreased energy consumption and freight transport in the E.U. Globally, the pace of renewable energy growth has been accelerating, the report said.

Low on Natural Gas, China
Cities Will Face Choking Air Pollution
In a push to curb air pollution, China has been urging its cities to rely more heavily on natural gas and less on coal. But a shortage of natural gas is threatening that goal, as urban populations boom and domestic gas production lags, Reuters reports
. Chinese officials have said that to reduce air pollution the most densely populated parts of Beijing should use only gas heat, which limits the supply of natural gas for smaller cities and forces those cities to rely on coal. Pollution levels in Chinese cities commonly exceed World Health Organization guidelines by 40 to 50 times. The problem is most pronounced in northern China, where air pollution from burning coal has already shortened life expectancy by 5.5 years compared to the southern part of the country. China's natural gas shortage is expected to be 10 percent higher this year than last year, since more users have switched from coal. Authorities are rationing natural gas and prioritizing its use for homes and transportation, but experts don't expect the shortage to subside anytime soon.

Three Western U.S. States And
British Columbia Sign Climate Agreement
The governors of California, Oregon, and Washington, together with the premier of British Columbia, have signed a pact to coordinate efforts to combat global warming. With a combined GDP of $2.8 trillion and a population of 53 million people, the three states and the Canadian province represent the world's fifth largest economy. The leaders agreed to a dozen actions aimed at curbing greenhouse gas emissions, including streamlining permits for renewable energy projects, improving the electric power grid, supporting more research on ocean acidification, and expanding government purchases of electric vehicles, the San Jose Mercury News reports
. Environmentalists have praised the agreement, but, as Jeremy Carl, an energy policy fellow at Stanford University, noted, "The devil will be in the details, whether they do anything substantive or whether it turns out to be a time-wasting exercise."

Underground Heat From
Cities Could Help Power Them, Study Says
The heat generated by urban areas and their buildings, factories, sewers, and transportation systems could be used to power those cities, according to a new study by German and Swiss researchers
. Thermal energy produced by the so-called "urban heat island effect" warms shallow aquifers lying below cities, and geothermal and groundwater heat pumps could tap into those warm reservoirs to heat and cool buildings, the scientists say. In the southwest German city of Karlsruhe, the researchers found that the city of 300,000 generated 1 petajoule of heat per year — enough to heat 18,000 households. Karlsruhe's underground heat production increased by about 10 percent over the past three decades, the team reported in Environmental Science and Technology
. The biggest contributors to the city's underground heat flux were its densely populated residential areas and surface temperature increases associated with paving. Sewage pipes, underground district heating networks, and thermal waste water discharges also contribute to warming shallow aquifers, the study found.

Major Pension Funds Question
Long-Term Outlook for Fossil Fuel Profits
Leaders from some of the largest pension funds in the U.S. and the world are concerned about the future profitability of fossil fuel companies, and they have asked those companies to report on their plans for managing a long-term shift
toward renewable energy. Managers of 70 major pension funds, which together control about $3 trillion in investments, asked 45 of the world's largest coal, oil, gas, and electric power companies to complete the profitability studies by spring. The pension funds are concerned that, because large investments in fossil fuel exploration take decades to recoup, future legislation could limit production or regulate expensive pollution controls that will significantly cut profitability. "The scientific trajectory that we're on is clearly in conflict" with the business strategy of the companies
, Jack Ehnes, the head of the California's State Teachers' Retirement System, told the AP. "We've been pleasantly surprised by the seriousness" of some of the fossil fuel companies, who are "not just blowing us off," a spokesman for the coalition that is coordinating the efforts told the AP.

Electric Vehicle Sales
On the Rise in 2013, New Analysis Shows
By the end of August, 59,000 electric vehicles had been sold in the U.S. this year — more than during all of 2012, a new report from the Union of Concerned Scientists (UCS)
shows. Over the past three years,
Americans purchased more than 140,000 electric vehicles (EVs), which have saved more than 40 million gallons of gas each year, the report notes. California is the leader, with 29 percent of all U.S. plug-in vehicle purchases made this year. EV sales rates have more than doubled in that state over the past year, according to the report. Although East and West coast cities continue to be hotspots for EV sales, purchases are picking up in cities like Denver, St. Louis, and Dallas, the report says

French Utility Company
Agrees to Build Major Nuclear Plant in U.K.
The British government and the French state-controlled utility company, EDF Group, have agreed to build the U.K.'s first nuclear power plant in a generation. The new plant, to be built at Hinkley Point in southwest England, is part of the British government's ongoing efforts to cut carbon emissions in half by the mid-2020s. To meet that goal, the U.K. plans to renew some of its existing nuclear plants and build several new plants to replace aging ones, the New York Times reports
. Once completed, the Hinkley Point nuclear power station will supply 7 percent of the country's electricity — enough to power 6 million homes. Consumers and taxpayers will cover most of the projected £16 ($26 billion) overall cost, but the proposed project is expected to face opposition since EDF will be guaranteed a price of roughly £90 ($145) per megawatt hour for 35 years, a rate that is considerably higher than current electricity costs.

Austrian Team Wins U.S.
Department of Energy Solar Competition
Employing creative ventilation and natural wood, a team from Austria won the 2013 Solar Decathlon
, a biennial competition for solar houses sponsored by U.S.
Department of Energy. The winning design features large living spaces with natural ventilation that helps the house maintain comfortable temperature and humidity levels, and is 96 percent wood. "It was important to us to use wood, because we have a lot of forests in Austria," team member Philipp Klebert told Fast Co.Exist
. "We wanted to make a statement about sustainability in that respect." Floor-to-ceiling and wall-to-wall sliding-glass doors, combined with an open floor plan, cool the house quickly and with minimal energy consumption. Among other guidelines, all Solar Decathlon entries must produce as much solar energy as they consume, and houses are scored in 10 categories
ranging from affordability to home entertainment. One of the team's sponsors is planning to market the design, perhaps as a self-assembly kit, Fast Co.Exist reports.

Excess Radioactivity and Metals
Found in Pennsylvania Fracking Wastewater
Researchers found high levels of radioactivity, metals, and salts in sediments and water downstream from a Pennsylvania facility that treats fracking wastewater. Radioactivity levels downstream of the treatment plant were about 200 times higher than in surrounding areas, and concentrations of some salts and metals were also higher than background levels, the scientists reported in Environmental Science and Technology
. The Duke University team traced the radioactivity's source to the Marcellus Shale formation, which is naturally high in salts and radioactivity. Although the treatment plant removes more than 90 percent of the radioactive metals radium and barium, the effluent still exceeds federal limits for radioactive waste disposal, the researchers said. Plants, fish, and other organisms near the facility are potentially at risk for radium bioaccumulation. Downstream, carcinogenic byproducts can form when water with excess levels of the salt bromide mixes with disinfection chemicals at municipal drinking water plants, the study said. A mile downstream from the treatment facility, bromide levels were 40 times higher than background levels, the researchers reported.

Ikea to Sell Home Solar Panels
In All British Stores Within a Year
The Swedish furniture retailer Ikea will begin selling residential solar panels in its 17 UK stores within the next 10 months. The basic package's $9,500 price tag will include 18 panels, installation, maintenance,
design consultation, and energy monitoring. With energy savings and current green energy subsidies in the UK, consumers should typically earn as much as $1,244 per year and break even in about seven years, Ikea said. Great Britain's heavily subsidized green energy market is smaller than other European countries', but it has shown steady growth, rising 25 percent in the last year, the Guardian reports
. The decision by the world's largest furniture retailer comes after a successful test run at a store outside London, where solar panel sales averaged one unit per day. Ikea has not announced plans to sell units in the U.S., where some utility companies have sought an end to public subsidies of
residential solar installations.

IPCC Scientists Warn
Of Upper Limit on CO2 Emissions
Saying it is 95 percent certain that humans have caused most of the global warming of the last half-century, scientists with the Intergovernmental Panel on Climate Change (IPCC) warned today that the world can afford to burn about 1 trillion tons of carbon
before facing extreme climate change. The IPCC’s working group on the physical sciences for the first time set an upper limit on CO2 emissions, contending that humanity can combust only one-third of the 3 trillion tons of fossil fuels that still remain in the ground. If carbon emissions continue at their current pace, IPCC scientists forecast that the trillionth ton of carbon will be released around 2040, and beyond that the world will face potentially destabilizing temperature increases exceeding 2 degrees C, or 3.6 degrees F. The physical sciences report,
compiled by hundreds of scientists and released in Stockholm, marked the first time that the IPCC had forecast that sea levels could rise by as much as three feet this century. The physical sciences report is the first of several to be released in the next year in advance of the 2014 publication of the IPCC’s fifth report on global climate change.

U.S. Places CO2 Limits
On New Coal-Fired Power Plants
The U.S. Environmental Protection Agency will for the first time begin regulating carbon dioxide emissions from new coal- and natural gas-fired power plants
under the Clean Air Act, EPA Adminstrator Gina McCarthy announced. Speaking in Washington, McCarthy said, “Climate change is real, human activities are fueling that change,
and we must take action to avoid the most devastating consequences.” The EPA regulations, which the coal industry vows to challenge in court, will require new coal plants to emit fewer than 1,100 pounds of carbon dioxide per megawatt hour, considerably lower than the average 1,800 pounds of CO2 per megawatt hour currently produced by coal-fired power plants. Such limits would require the new plants to deploy carbon capture and storage (CCS) technology, which has not been used on a wide scale. The difficulty of using CCS technology will be at the heart of lawsuits challenging the EPA move, industry officials say.

Fracked Shale Formations
Could Store Carbon Dioxide, Study Says
Storing carbon dioxide in the same shale formations that produce natural gas may be an effective way to sequester carbon dioxide produced by fossil fuel-burning power plants, according to a U.S. study
. Computer models by researchers at the University of
Virginia suggest the Marcellus Shale, a 600-square-mile formation in the northeastern U.S. that is a center of hydrofracturing natural gas, is capable of storing half the CO2 emitted by U.S. coal plants from now to 2030. Fracked shale wells are good candidates for carbon storage because CO2 can be injected in much the same way that natural gas was extracted, the researchers say. Fracking involves injecting pressurized fluids in wells to fracture the shale rock, which creates cracks that let gas seep out. The authors of this study suggest those networks of cracks could be filled with CO2 before sealing the natural gas wells.

Grid-Scale Batteries Make Sense
For Solar Energy, But Not Wind, Study Says
When renewable energy sources such as solar and wind farms generate more electricity than consumers need, storing the excess doesn't always make sense, say researchers from Stanford University
. Large, grid-scale batteries capable of storing the extra electricity are resource-intensive and costly to manufacture and maintain — sometimes more so than the energy they're used to store. "You wouldn't spend a $100 on a safe to store a $10 watch," said Michael Dale, who co-authored the study in the journal Energy & Environmental Science
. "Likewise, it's not sensible to build energetically expensive batteries for an energetically cheap resource like wind." Economically, it makes more sense to shut down wind energy production when consumer demand is low than it does to maintain battery systems to store excess wind energy, the study said. But battery storage does make sense for photovoltaic systems, the researchers say
, because solar panels and solar farms require more energy to build and maintain.

Ecuador Abandons Moratorium
On Oil Drilling in Biodiverse Yasuni Park
The Ecuadorian government has abandoned its moratorium on oil drilling in Yasuni National Park
as a proposal to protect the park with the help of international donations fell apart. In a nationally televised speech, President Rafael Correa blamed the failure of the ambitious conservation plan on a lack of funds, saying that a UN-administered trust fund had raised only $13 million of the $3.6 billion target. Located in eastern Ecuador, where the Amazon basin ascends into the Andes, Yasuni is home to an unprecedented number of animal and plant species
. According to a 2010 study
, one section of the park held at least 200 species of mammals, 247 amphibian and reptile species, and 550 species of birds. But Yasuni also sits atop an estimated 1 billion barrels of oil. Correa had said Ecuador would forego oil income and protect the park if foreign donors would contribute billions of dollars to compensate for the loss of oil revenue.

Conventional Hybrids Better
For Climate than EVs in Most U.S. States
Conventional gas-powered hybrid vehicles are still better for the climate than all-electric cars in most U.S. states, in part because these states still rely heavily on fossil fuels to produce electricity, according to a new report
. In 39 states, high-efficiency hybrids, such as the
Toyota Prius, produce fewer carbon emissions during their lifecycle than the least-polluting electric cars, an analysis by Climate Central found. Although an increased reliance on cleaner energy sources in some parts of the country doubled the number of states (32) where driving electric cars would be more environmentally friendly, that advantage disappeared when analysts also considered the high emissions associated with building the batteries and other components for the EVs. In 11 states, the best all-electric cars are better for the environment than gas-powered hybrids, even when manufacturing is taken into account. In 26 states, plug-in hybrid cars are the most climate-friendly vehicles, the analysis found.

Timelapse Map Illustrates
Steep Growth of U.S. Wind Energy
The U.S. installed more than 13 gigawatts of new wind energy capacity in 2012, nearly doubling the amount of wind power installations added in 2011 and pushing the
total capacity connected to the grid nationally to 60 gigawatts, according to a new report from the U.S. Department of Energy
(DOE). That capacity represents enough electricity to power 15 million homes annually, officials say, adding that for the first time wind energy has become the top source of new electricity generation in the U.S. To coincide with the report, the DOE published an interactive map
illustrating the steep growth in wind projects nationwide, particularly in the last decade. The map shows that until the mid-1990s, only a few dozen wind projects existed, all in California. But by 2000, projects started appearing in states nationwide, particularly in Texas and Iowa. In the past two decades the number of wind energy projects has increased from 49 to 815, the DOE said.

European Investment Bank
Will Not Finance Most Coal Power Stations
The European Investment Bank (EIB), the main lending arm of the European Union, has decided to stop financing most coal-fired power plants
, part of an effort to help the 28-nation bloc meet ambitious greenhouse gas reduction targets by 2030. The EIB says that new and refurbished coal-fired power stations will be ineligible for funding unless they emit less than 550 grams of carbon dioxide per kilowatt hour, a standard that traditional coal power plants would be unable to meet. Power stations that burn coal would only be able to meet the standards if they also produce heat for municipal or commercial heating systems or burned biomass. The EIB says it plans to further tighten its emissions standards for coal- and natural gas-fired power plants in the future.

‘Demand Response’ Programs
Saved Crucial Electricity During Heat Wave
As electricity producers struggled to supply power during last week’s heat wave along the U.S. East Coast, so-called “demand response” programs — which enable utilities to remotely reduce power usage in participating businesses and homes — were vital in avoiding blackouts
, utility officials said. The Wall Street Journal
reports that as electricity usage in New York state set a record on Friday, demand response programs produced energy savings equivalent to the output of two large power plants, just as the state was running dangerously low on power. Demand response programs enable utilities to dim lights, turn down air conditioners, and delay freezer-defrost cycles in the freezer cases of stores. Participating businesses and individuals get credits on their utility bills. Numerous states have demand response programs, and federal officials say these programs are capable of cutting peak U.S. electricity demand by 72,000 megawatts, or 9.2 percent.

Europe’s Offshore Wind Sector
Is Growing, But Troubles Lie Ahead
European nations installed a record number of offshore wind turbines
during the first half of 2013, adding more than twice the capacity installed during the same period in 2012, according to the European Wind Energy Association (EWEA), an industry group. A total of 277 new turbines in seven wind farms were fully connected to the grid during the six-month period, adding 1,045 megawatts of capacity, with another 130 turbines installed but awaiting connection, the group says in a new report
. Although the new turbines bumped Europe’s total offshore wind energy capacity to 6,040 megawatts, officials say the sector’s growth is already slowing as a result of regulatory uncertainty in key countries. While European nations such as Germany and the UK have relied on large-scale wind projects to achieve renewable energy targets by 2020, the lack of a binding target for 2030 will cause growth to stall, said Justin Wilkes, EWEA’s policy director. “Financing of new projects has slowed down with only one project reaching financial close so far this year,” he said.
