Possible with Advances in Semiconductors
New semiconductor technology is advancing the development of house windows that could double as solar panels, according to scientists
from Los Alamos National Lab and Italy. Their research into so-called
Solar-harvesting materials under UV light
"quantum dots" — ultra-small bits of semiconductors that transmit energy extremely efficiently and can be tuned toward specific colors — shows that quantum dots can be used in transparent materials to harvest sunlight with efficiencies comparable to standard solar panels. When highly transparent materials are embedded with quantum dots, they are known as luminescent solar concentrators (LSCs); the structures can absorb sunlight and re-radiate it at longer wavelengths directed toward the edge of the slab, where the energy is collected by a solar cell. In tests using large LSC slabs (sized in tens of centimeters), researchers reported harvesting photons at roughly 10 percent efficiency. Typical photovoltaic solar panels have an average efficiency of about 15 percent.

Despite Stark Warnings,
UN Panel Finds Signs of Hope on Climate
Although greenhouse gas emissions continue to rise at an alarming rate, governments are beginning to embrace carbon-cutting initiatives, while technological advances are sharply reducing the cost of deploying solar and wind power, according to the latest report by the Intergovernmental Panel on Climate Change.
The working group report on climate mitigation
, released in Berlin, said that global CO2 emissions have risen about 2.2 percent a year this century — twice the rate of the last few decades of the 20th century — and that holding temperature increases to 2 degrees C (3.6 F) can only be achieved through an intensive push over the next 15 years. But the report also said that the political will to reduce carbon emissions seems to be rising around the world, and that shifting the global energy system from fossil fuels to zero- or low-carbon sources would reduce economic growth by only about .06 percent per year.
“The loss in consumption is relatively modest,” said IPCC chairman Rajendra Pachauri. “The longer we delay the higher would be the cost.”

Solar Panels Could Beam Power
From Space Down to Earth, U.S. Navy Says
Researchers from the U.S. military are developing technology that would harvest solar energy in space and beam it down to Earth, according to
the Naval Research Laboratory. Although the concept seems futuristic, the
Navy is currently testing two prototype designs, both of which combine solar panels with electronic components that convert the energy to radio waves and transmit it to Earth. Eventually, engineers plan to use robotic vehicles to transport the panels to space and assemble them into a 1-kilometer wide satellite orbiting the planet. Theoretically, harvesting solar energy in space is more efficient than on Earth, because panels can collect sunlight around the clock and regardless of weather conditions. The U.S. military, currently the world's largest oil consumer, is eager to develop the technology to save money on fuel and simplify military deployments. But the private sector also has plans for the technology: California utility company Pacific Gas & Electric plans to buy space solar power by 2016.
Comment: e360 Point/Counterpoint Debate
On University Fossil Fuel Divestment
Scientists Charles H. Greene, of Cornell University, and Daniel M. Kammen, of the University of California, Berkeley, offer commentary on the recent Yale Environment 360 Point
articles on the
Student protest at Tufts University last spring
issue of whether universities should take a stand against climate change by divesting from companies that produce oil, natural gas, or coal. Greene and Kammen make the case that the movement to divest is gaining ground on U.S. campuses and will eventually succeed because fossil fuels are increasingly seen as a potentially risky investment. "We predict that divestment at the nation’s colleges and universities will occur much more rapidly than anybody imagined at the start of the campaign just over a year ago," they write.

Wind Turbine in a Blimp
Can Bring Power to Remote Locations
A Massachusetts company will soon deploy a portable wind energy system using a conventional turbine blade inside a cylindrical blimp that floats about 1,000 feet above the ground
, drawing on the stronger winds at
. The Buoyant Airborne Turbine (BAT), developed by Altaeros
, is designed to be used in off-the-grid locations where importing diesel fuel or other energy is expensive. The company recently announced a $1.3 million demonstration project in Alaska that will supply power to about a dozen homes. Altaeros says it is also working on deals to install projects in remote locations in Canada and Australia. The BAT, made of industrial fabric, sends power back via high-strength tethers that hold it to the ground. Altaeros is one of several companies developing wind turbines that hover above the earth or fly, including Makani
, which has invented a turbine that looks like a flying wing. Makani was acquired last year by Google X.

Ride-Sharing Could Cut Taxi
Trips by 40 Percent in NYC, Analysis Shows
New interactive maps from MIT analyze the potential environmental and economic savings of ride-sharing in dense urban areas — in particular, the benefits of sharing taxicabs in New York City. The project, called
, uses data from 170 million trips made by New York City's 13,500 taxis in 2011. High-resolution GPS coordinates and timestamps for each trip allowed researchers to pinpoint locations in the city that are high-traffic hubs for taxi pick-ups and drop-offs, as well as calculate fare savings, decreases in total miles traveled, and cuts in CO2 emissions if ride-sharing existed. The researchers found that taxi-sharing could reduce the number of trips by 40 percent with only minimal inconvenience to the passengers. The findings highlight the potential benefits of ride-sharing in New York and other cities, including lower vehicle emissions, reduced congestion, and savings in time and money.

Koch Brothers Biggest Lease
Holders in Alberta Tar Sands, Report Finds
The largest lease holder in Canada's oil sands is a subsidiary of Koch Industries
, the conglomerate that is the source of the fortune owned by the controversial conservative political donors, Charles and David Koch. The Koch's holdings in the tar sands were disclosed by an activist group
that analyzed mineral records of the Alberta government. The Koch subsidiary holds leases on at least 1.1 million acres in the northern Alberta oil sands, which span roughly 35 million acres; other industry experts estimate the total Koch holdings could be closer to 2 million acres. That puts Koch Industries ahead of energy heavyweights Royal Dutch Shell and Conoco Phillips, both of which lease significant acreage in the oil sands. The findings are likely to inflame the debate surrounding the proposed Keystone XL pipeline — which would transport tar sands oil to refineries in Texas — although the Koch's company has not reserved space in the pipeline. Activists argue that the Kochs do have a stake in the outcome of the Keystone XL battle because the pipeline would drive down crude oil transportation costs, benefiting all lease holders.

Solar City Partnering With
Best Buy to Sell Residential Solar Leases
Solar City, a company that installs and leases solar panels to homeowners, is partnering
with big-box electronics seller Best Buy in hopes of boosting solar sales in California, Arizona, Hawaii, Oregon, and New
A Solar City residential installation in Hawaii
York. Solar City will station salespeople in 60 stores throughout those states to pitch the benefits of their 20-year solar contracts directly to consumers, and Best Buy will take a cut of the sales. Based on a homeowner's utility company and monthly electric bill, Solar City representatives will be able to quickly give potential customers an estimate of the costs and savings associated with a solar lease. Leasing enables a homeowner to avoid the large upfront costs associated with purchasing and installing solar panels by spreading those investments over a 20-year lease and locking in a set rate for electricity generated by the panels. Residential solar installations have accelerated in recent years due largely to the popularity of leasing programs, with 2013 showing the fastest growth ever.

Nine Chinese Cities Outpaced
Beijing in Air Pollution in 2013, Report Says
China's air pollution problems are more severe and widespread than previously thought, with nine cities experiencing more days of extreme air pollution than Beijing in 2013, according to
a new analysis by Greenpeace's Energy Desk. Fine particulate (PM2.5) pollution plagued dozens of cities and millions of people in China — most of them outside of Beijing, although the Chinese capital captured the most air pollution headlines last year. The city of Xingtai, southwest of the capital, fared worst, with 129 days of emergency air pollution — more than doubling Beijing's 60 days. More than half of the cities in the top 10 are in Hebei province south of Beijing, where many steel, cement, and coal-fired power plants are located. "There are now millions of Chinese people living in cities with air pollution above emergency levels for a third of the year, while other urban areas have gone a whole 12-month period with hardly any days of good-quality air," said a member of Greenpeace's East Asia climate and energy campaign. Beijing had only 13 days ranked as "good" on the U.S. air quality scale, along with one day considered "beyond index," or off the pollution scale.

'Space Frame' Wind Tower
Allows Turbines to Be Built in Remote Places
New wind power technology could bring turbines to hard-to-reach locations, according to engineers from General Electric
. The company has developed a new
type of wind tower, dubbed the "Space Frame Tower," consisting of metal latticework wrapped in weather-resistant fiberglass. Unlike conventional steel tube wind towers, the latticework can be bolted together on-site, which means the tower's framework can be transported using standard shipping containers and trucks, allowing taller wind towers to be installed in locations previously inaccessible to the longer trucks needed to transport conventional towers. The Space Frame Tower also has a five-leg base that's wider than conventional towers, increasing stability and ultimately allowing it to reach heights up to 450 feet — an advantage at sites where higher turbines can reach stronger winds. A 318-foot tall prototype is up and running in Tehachapi, California, with a 2.75 megawatt turbine nearly 400 feet wide.

U.S. Car-Sharing Programs Have
Taken 500,000 Cars off Roads, Report Says
The rapid growth of car-sharing programs has cut the number of vehicles on U.S. roads by more than half a million, according to new research
by AlixPartners, a consultancy group with clients in the automotive industry. The trend will continue beyond 2020, the group projects, at which point 4 million people will be participating in car-sharing programs and 1.2 million fewer cars will be on the road. Of the 10 cities surveyed, residents of Boston, home of the Zipcar company, were most aware of car-sharing programs. Young people and, surprisingly, households with children were least likely to own their own cars, the survey said. Roughly half of the people who had tried car-sharing had already decided not to purchase or lease their own car, and did not plan to do so in the future. Rather than environmental concerns, nearly 60 percent of interviewees said cost and convenience led them to participate in car-sharing.

Atlanta Leads U.S. in
Electric Vehicle Sales Growth
Atlanta is the fastest growing market for electric cars in the U.S., according to an analysis
by the electric vehicle charging network ChargePoint. Electric vehicle (EV) sales in Atlanta jumped by 52 percent from the third quarter to the fourth quarter of 2013, with more than
3,000 EVs sold in the final three months of the year, according to state motor vehicle records. Washington, D.C., was the second-fastest growing market, with a 21 percent increase in sales, and Portland, Oregon, had the third-fastest growth, at 19.4 percent. While Los Angeles added the most EVs — more than 5,000 — to its streets, for a 19 percent growth rate, Atlanta outpaced it on a per capita and percent growth basis. Nationally, EV sales grew by nearly 450 percent
in the first three quarters of 2013 compared to the same period in 2012. ChargePoint's CEO speculated that popularity is increasing because charging station networks have expanded and EV designs have improved. "We’re well on our way to having twice the number of EVs on the road by the end of 2014," he said.

Large Offshore Wind Farms
Could Soften Blow of Hurricanes, Study Says
Offshore wind farms with thousands of wind turbines could have sapped much of the power of hurricanes Sandy, Katrina, and Isaac, significantly slowing their wind speeds, decreasing their accompanying storm surges, and possibly preventing billions of dollars in damages, according to a new study
. Computer models
used in the study said that deploying tens of thousands of offshore wind turbines could absorb enough energy from a hurricane to reduce peak wind speeds by 56 to 92 mph and storm surges by 6 to 79 percent. "We found that when wind turbines are present, they slow down the outer rotation winds of a hurricane," said Stanford engineer Mark Jacobson, who led the research. "This feeds back to decrease wave height ... which in turn slows the winds of the entire hurricane and dissipates it faster." For Hurricane Katrina, a massive turbine array could have slowed wind speeds by 58 percent and storm surge by 79 percent, and for Sandy wind speeds could have been cut by 14 percent and storm surge by 34 percent, according to findings published in Nature Climate Change

Maps Show Extent of
Oil and Gas Drilling in Southwest Wyoming
Oil and gas wells, including those involved in hydraulic fracturing operations, scar a major portion of southwest Wyoming, according to a recent analysis by the U.S. Geological Survey
. Nearly 17,000 well pads and former
drilling areas associated with oil and natural gas production were identified in satellite images across a 30,000-square-mile region. The maps include well scars dating from around 1900, when oil drilling started in the region, up to 2009, at which point natural gas extraction far outweighed oil production. Since then, production has only intensified in Wyoming, a leading state in the U.S.'s unconventional oil and gas boom. The mapping effort, a first step in determining how oil and gas drilling operations impact wildlife and ecosystems, focused on southwestern Wyoming because it not only has some of the nation's largest natural gas reserves, but also because the region has high-quality wildlife habitat and encompasses a major portion of the country's remaining intact sagebrush steppe.

New Maps Pinpointing Wind
Turbines Will Help Track Effects on Wildlife
More than 47,000 wind turbines dot the U.S. landscape, predominantly clustered in the Midwest and Great Plains, as a new interactive tool
developed by the U.S. Geological Survey (USGS) shows. The maps — the first
publicly-available, nationwide data set for wind energy generation — show the locations of every turbine in the U.S., from large wind farms to single turbines, and are accurate to within 10 meters. The maps are part of the USGS's effort to assess how wind turbines impact wildlife, and they show detailed technical information such as the make, model, height, area of the turbine blades, and capacity of each turbine. Turbine-level data will improve scientists’ ability to study wildlife collisions, the wakes causes by wind turbines, the interaction between wind turbines and ground-based radar, and how wind energy facilities overlap with migratory flyways, the USGS says.

Climate Benefits of Natural Gas
Are Questioned in A Major New Report
The U.S. Environmental Protection Agency has been underestimating methane leaks from natural gas production and use by 25 to 75 percent, according to a comprehensive assessment
of more than 200 studies. When the methane leaks are accounted for, natural gas contributes to climate change more than industry and the EPA have claimed, concludes the report by a team of U.S. scientists. In some cases, natural gas contributes to warming more than other fossil fuel sources. For instance, fueling trucks and buses with natural gas instead of diesel likely increases emissions, because diesel engines are relatively efficient, according to the researchers. Natural gas has been touted as an important "bridge fuel" because it emits less CO2 during combustion than oil and coal. Recently, though, studies have indicated that leaks of methane, a more potent greenhouse gas than CO2, during natural gas production, transportation, and consumption may offset its climate benefits. The new report, published in Science
, synthesized the results of 20 years' worth of methane leakage studies.

U.S. State Department Report
Boosts Prospects of Keystone XL Pipeline
In a long-awaited report, the U.S. State Department has concluded that the carbon-heavy oil from Alberta's tar sands will be extracted whether or not the Keystone XL pipeline is built, improving the prospects
that the highly controversial project will be built. In an environmental impact statement
that was six years in the making, the State Department concludes that the process of extracting and burning tar sands oil creates 17 percent more greenhouse gases than traditional oil, but that the heavily polluting oil will be brought to market with or without the pipeline. "It's unlikely for one pipeline to change the overall development of the oil sands," said a State Department official. If completed, the pipeline would carry 830,000 barrels of oil a day from Alberta to refineries on the coast of the Gulf of Mexico. President Obama will make the final decision on the Keystone XL pipeline and he vowed last year that he would approve the pipeline only if it would not "significantly exacerbate" the problem of carbon emissions. Environmental activists such as Bill McKibben of 350.org have said it would be "game over" for the climate if Keystone XL is built.

Driven by State Incentives
Electric Cars Top Vehicle Sales in Norway
Norwegians have been snapping up electric cars: In the last three months of 2013, the Tesla Model S and Nissan Leaf outsold all other cars, including conventionally fueled models. But rather than environmental concerns,
An EV charges up in Oslo
a host of government incentives — totaling an estimated $8,300 per vehicle — are largely driving the boom, the Guardian reports
. Norway, a country of only 5 million people, currently has around 21,000 electric vehicles (EVs) on the roads, compared to 70,000 EVs among 313 million Americans and 5,000 EVs among 63 million people in the UK. More than 1,200 EVs are being sold in Norway per month thanks to incentives that include free electricity for recharging, lower sales tax rates, waived tolls, free parking, insurance discounts, and permission to drive in bus lanes, which are less crowded. The EV rush is expected to slow, however, as bus lanes become more crowded, and the government plans to end financial incentives once 50,000 EVs are registered, which could occur by 2016.

Changes in Humidity
Are Used to Generate Electricity
Researchers have created a new kind of generator that uses bacterial spores to harness the untapped power of evaporating water
. Scientists from Harvard and Columbia universities have created small, prototype generators by coating a sheet of rubber with a soil
Bacillus subtilis bacterial spores
bacterium, Bacillus subtilis
, that greatly expands and contracts with changes in humidity. Building a generator out of Legos, a miniature fan, a magnet, and the spore-covered sheet of latex, the researchers used the humidity-driven flexing of the rubber sheet to drive the movement of the magnet, which generated electricity. The developers of the potential renewable energy technology said that large electrical generators could one day be powered by changes in humidity from sun-warmed ponds and harbors. The scientists said that moistening and then drying a pound of the spores produces enough force to lift a car one meter. “If this technology is developed fully, it has a very promising endgame,” said Columbia University researcher Ozgur Sahin.

More Crude Oil Spilled by
U.S. Trains in 2013 Than Previous 40 Years
U.S. trains spilled 1.15 million gallons of crude oil in 2013 — more than was spilled in the nearly 40 years since officials began tracking such accidents, federal data show
. The majority of that volume came from two major derailments: a November incident in Alabama that spilled 750,000 gallons and a December incident in North Dakota that officials estimate spilled 400,000 gallons. Those incidents, as well as smaller spills, have added to growing concerns over the safety of using railways
to transport crude as U.S. oil production surges in the upper Midwest. From 1975 to 2012, a total of 800,000 gallons of crude were spilled during rail transport. Excluding the two major derailments from the 2013 total, 11,000 gallons of crude were spilled last year — more than the previous two years combined. The data do not include a 1.5 million-gallon spill that killed 47 people in Lac-Mégantic, Quebec, in July.

Google's Acquisition of Nest
Expected to Boost Smart Grid Expansion
Google's purchase of Nest, a leading manufacturer of smart thermostats, further deepens the Internet search giant's involvement in the green energy sector and is likely to help accelerate development of a more efficient
smart grid, experts say
. Google has already invested $300 million in distributed solar companies, which have been helping homeowners install photovoltaic panels to offset their conventional grid-based power consumption. The success of distributed solar hinges on effective smart-metering, and acquiring Nest — whose thermostats can be controlled remotely and can track and reduce energy consumption — could help Google gain valuable insight into millions of individuals' daily power consumption patterns, Quartz reports. As power grids and meters get "smarter," demand for technology like Nest's thermostats will likely grow; incorporating distributed solar energy sources should become easier for households, as well. The $3.2 billion deal will also give Google access to Nest Energy Services, a branch of the company that manages partnerships between Nest and U.S. power companies.
Interview: Activist Kumi Naidoo
On Russia and the Climate Struggle
Kumi Naidoo, the international executive director of Greenpeace, is intimately familiar with the Prirazlomnaya drilling platform in the Russian Arctic. In 2012, he and five other Greenpeace activists were hosed down with frigid water and pelted with pieces of metal as they attempted to climb aboard the platform.
Greenpeace and Prirazlomnaya were back in the news recently when 28 Greenpeace members were arrested and held for several months for storming the rig before being released in December. In an interview with Yale Environment 360
, Naidoo talks about what’s needed to get global climate talks off the ground and launch a green energy revolution, and the reason his activist organization has decided to take such a strong stand against oil drilling in the rapidly melting Arctic Ocean. "We went back [to Prirazlomnaya]," says Naidoo, "because we’re trying to draw a line in the ice, because once this starts it will have breached another threshold of meeting our rapacious appetite for oil and gas in the most fragile of environments." Read the interview.

Natural Gas Has Sharply
Reduced Emissions from Power Plants
The dramatic increase in using natural gas to produce electricity in the United States has led to an equally dramatic decline
in the amount of pollutants and carbon dioxide emitted from the nation’s power plants, according to a new study. The study, conducted by researchers at the National Oceanic and Atmospheric Administration, showed that the switch from coal-fired to natural gas-fired power plants has reduced CO2 emissions by 23 percent and emissions of nitrogen oxides and sulfur dioxide by 40 and 44 percent, respectively. Examining power plant emissions from 1997 to 2012, the scientists found that new combined-cycle natural gas-fired power plants — which use two heat engines in tandem to convert a higher fraction of heat into electrical energy — emit less than half the amount of CO2 as coal-fired power plants. The study, to be published in the journal Earth’s Future
, said that the fraction of electricity produced in the U.S. from coal fell from 83 percent in 1997 to 59 percent in 2012. Meanwhile, the fraction of electricity generated by combined-cycle natural gas plants rose from zero to 34 percent.

China Approves Major
Increase in Huge Coal Mining Projects
In 2013, the Chinese government approved 15 large coal mining projects
that will produce more than 100 million new tons of coal a year. The expansion will lead to a 2 to 3 percent growth in coal production over the next several years, even as the country announced moves to reduce the severe air pollution
choking major cities such as Beijing. Chinese officials will increase coal production while reducing pollution in population centers by closing outdated coal plants and creating huge “coal bases” that will mine and burn coal in remote regions of northwestern China, such as Inner Mongolia. Those bases, which will cost $8.9 billion to build, will generate electricity that will be transferred over an improved electricity grid to cities in China’s central and eastern regions. Deng Ping, an environmental campaigner with Greenpeace, said the scale of the new coal bases is unprecedented for China, adding, “Despite the climate change pressure, water resource scarcity, and other environmental problems, the coal industry is still expanding fast in northwest China.”

Suburbs Offset Low Carbon
Footprints of Major U.S. Cities, Study Finds
City-dwellers in the U.S. have significantly smaller per-capita carbon footprints than their rural counterparts, according to new research
from the University of California, Berkeley. But the carbon-intense suburbs surrounding major cities essentially cancel out the small carbon footprints of city residents,
the study found. Vehicle emissions accounted for the majority of carbon dioxide produced in the suburbs, reflecting suburbanites' longer commutes to work, school, and stores. The study looked at 37 factors — including weather, income, home size, and transportation data — to estimate household carbon footprints. The average carbon footprint of households living in the center of large, densely populated cities is about 50 percent below the national average, while households in distant suburbs have carbon footprints up to twice the national average, according to the study published in Environmental Science & Technology

North Dakota Bakken Crude
More Explosive Than Expected, Officials Say
Crude oil from North Dakota's Bakken field may be more flammable and explosive than previously thought
, officials now say after a series of fiery railroad accidents. The crude may contain more flammable gasses, be highly corrosive, or more sulfurous than crude from other oil fields, according to the Pipeline and Hazardous Materials Safety Administration (PHMSA). The agency is warning Bakken oil producers to "sufficiently degasify" the crude oil before loading it into rail cars. On Monday, several tank cars carrying Bakken crude exploded after a collision on a remote stretch of track in North Dakota, and last July a runaway train carrying the crude derailed and exploded in Lac-Mégantic, Quebec, killing 47 people. U.S. railroads have asked manufacturers for safety upgrades to tank cars
that carry Bakken crude, which could cost the industry roughly $3 billion, Reuters estimates. Trains carried nearly 700,000 barrels of Bakken crude each day in October, a 67 percent increase over the previous year.

Hydropower "Battery" Could
Even Out Wind Energy Supply, Scientists Say
Norwegian hydropower stations could be linked to wind farms
and serve as giant "batteries" to even out power supply fluctuations, a Scandinavian research organization says. A major hurdle for renewable energy suppliers is intermittent power production — sometimes too much power is generated, other times too little, and periods of peak demand often don't coincide with periods of peak supply. By using excess electricity from windy periods to pump water uphill into reservoirs, hydroelectric power stations could smooth out the intermittent power supplied by large wind farms, Scandinavian researchers from the firm SINTEF say. At times of low wind energy supply, the stored water could be released through dam turbines and hydroelectricity would fill the gap. The plan requires updating and refurbishing existing Norwegian hydropower plants, which could increase their output potential by 11 to 18 gigawatts, enough to provide an adequate backup power supply.

Russian Oil Giant Becomes
First in World to Pump Oil From Arctic
The Russian national oil company Gazprom has begun drilling for oil at a highly contested site in the Arctic
. The oil field, an offshore site in the Russian Arctic known as Prirazlomnoye, drew international attention in September when a contingent of Greenpeace members boarded the platform in protest and were jailed in Russia for two months before being granted amnesty last week. The project, which is several years behind schedule, is the first in Russian history aimed at "developing the resources of the Arctic shelf," Gazprom said. Environmental groups say that no company has the technology or resources to deal with a massive oil spill in the harsh conditions of the Arctic Ocean. The oil giant Shell had planned exploratory drilling in the Arctic off the coast of Alaska, but temporarily shelved those plans last year after a series of mishaps. Gazprom says it has taken all necessary precautions to deal with a spill, Mongabay reports.

Renewable Energy Comprised
Total U.S. November Power Generation Gains
All of the additional electricity-generating capacity added by the U.S. last month came from renewable energy sources, according to a report from the Federal Energy Regulatory Commission (FERC)
. Solar, biomass, wind, geothermal, and hydropower projects provided 394 megawatts — 100 percent — of all new electricity generation that went on line in November. No new capacity was added from fossil fuels or nuclear power, FERC reported. Renewable energy sources also provided 99 percent of all new electricity-generating capacity in October. Although natural gas has been the biggest player in added capacity so far this year (52 percent), solar also made gains. It alone has made up roughly 21 percent of new power capacity so far in 2013, two-thirds more than its year-to-date total in 2012. Renewable sources now account for 15.9 percent of total U.S. generating capacity, which is more than nuclear (9.2 percent) and oil (4.05 percent) combined.
