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.

Los Angeles Becomes First
Major U.S. City to Adopt Cool Roof Rule
The Los Angeles City Council has voted unanimously to require "cool roofs" for all new and refurbished homes, becoming the first major U.S. city to do so
. "Cool roofs" incorporate light- and heat-reflecting building materials, which can lower the surface temperature of the roof by up to 50 degrees F on a hot day, according to Climate Resolve
, the local organization that pushed for the ordinance. Such roofs do not necessarily need to be white, the Global Cool Cities Alliance says; they can also be shades of gray, or even red. Research suggests that by mid-century temperatures in Los Angeles will increase by 3.7 to 5.4 degrees F, with the number of days above 95 degrees F tripling in the city's downtown. "The changes our region will face are significant, and we will have to adapt," said UCLA scientist Alex Hall, who led the research. The mandate will not cost homeowners additional money because of expanded incentives.

Australian Coal Projects
Threatened by Drop in Demand From China
Major Australian coal projects risk losing value due to falling demand from China, where leaders are increasingly concerned about growing public anger over severe air pollution, a new analysis from Oxford University
has found. Future coal mining projects are vulnerable to being "stranded" by a range of policy changes from the Chinese government, including environmental regulation, carbon pricing, investment in renewable energy, and energy efficiency, the report said. One expert told The Guardian
that global investors are already questioning the prudence of financing new fossil fuel projects
. Backers of a handful of upcoming Australian coal projects "should seek clarity" on the associated costs, the Oxford analysis warns. It also cautions that Australian state governments could suffer if projects are mothballed or abandoned. Of particular concern are two mega-mines supported by Australia's Prime Minister Tony Abbott
slated for development in Queensland. Once running at full capacity, the two projects combined would produce enough coal to emit more than 70 millions tons of CO2 a year.

U.S. Energy Department
Invests in Small-Scale Nuclear Reactors
Small, nearly meltdown-proof nuclear reactors are receiving a big boost from the U.S. Department of Energy
. The department will give a company in Corvallis, Oregon, as much as $226 million to develop so-called "small modular reactors," which can be used with many local power grids that can't accommodate conventional nuclear reactors. Because of the extremely low likelihood of meltdown, the next-generation, small-scale reactors are safer than many currently operating reactors, engineers say. The company, NuScale Power, plans to encase their reactors in something akin to a large thermos, which would sit at the bottom of a pool. If a reactor fails and threatens to overheat, the container would fill with water and remove excess heat without pumps or valves, which can sometimes fail. The Energy Department's investment is the second one in a $452 million, multi-year program to accelerate the development of such reactors. The reactor designs use water as a coolant, which is technologically conservative and increases the likelihood that the small modular reactors would be approved by the Nuclear Regulatory commission, The New York Times

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.
