For the first time ever, gas has usurped coal as the biggest producer of electricity in the US. Analysts say Obama administration’s proposed climate change rules are likely to establish gas as the predominant source of electricity as early as 2020.
Figures released by the US government’s Energy Information Administration (EIA) show that in April, natural gas produced 31.5 per cent of the country’s electricity and coal 30.2 per cent.
The interregnum will not last, with coal expected to average around 35.6 per cent of generation across 2015. But a decade ago, such an inversion was unthinkable. Americans got half their electricity from coal and just a fifth from natural gas. Now the two are neck and neck.
In April a glut of fracked gas from new shale regions drove the price of gas down to just $2.50/million Btu (British thermal unit, a widely-used measure of energy), a 35 per cent drop since February. This oversupply, combined with a routine seasonal shut down of coal plants, caused gas production to creep above coal for the first time.
“Power generators often use the spring months to take their plants offline for maintenance, especially coal plants. This maintenance period happened to coincide with a period of very low natural gas [prices],” said Tyler Hodge who works on the EIA’s Short-Term Energy Outlook.
Hodge said gas prices were expected to rise again in the coming months, and coal would reassert itself at the top of the production table when plants fire up again for the winter.
In 2012, gas prices fell even lower and production almost overtook coal, but coal returned to dominance. “So this [gas surge] is by no means irreversible,” said Michael Obeiter, a senior associate in the World Resources Institute’s climate programme. But he said the short term fluctuations in gas price were compounding an overall drift away from coal and the trend favoured “natural gas becoming the dominant source for electricity generation in the US in the coming years.”

Obama builds environmental legacy using Clean Air Act
Coral Davenport, NEW YORK TIMES
Taken together, the Clean Air Act regulations issued during the Obama administration have led to the creation of America’s first national policy for combating global warming and a fundamental reshaping of major sectors of the economy, specifically auto manufacturing and electric utilities. The regulations could ultimately shut down existing coal-fired power plants, freeze construction of new coal plants and end demand for the nation’s most polluting fuel.
President Obama could leave office with the most aggressive, far-reaching environmental legacy of any occupant of the White House. Yet it is very possible that not a single major environmental law will have passed during his two terms in Washington.
Instead, Mr. Obama has turned to the vast reach of the Clean Air Act of 1970, which some legal experts call the most powerful environmental law in the world. Faced with a Congress that has shut down his attempts to push through an environmental agenda, Mr. Obama is using the authority of the act passed at the birth of the environmental movement to issue a series of landmark regulations on air pollution, from soot to smog, to mercury and planet-warming carbon dioxide.
The Supreme Court could still overturn much of Mr. Obama’s environmental legacy, although the justices so far have upheld the regulations in three significant cases. More challenges are expected, the most recent of which was taken up by the court on Tuesday. The act, however, was designed by lawmakers in a Democratic Congress to give the Environmental Protection Agency, which was created at the same time, great flexibility in its interpretation of the law.

China-U.S. climate accord goals achievable; policies are already in place
Henry Fountain and John Schwartznov, THE NEW YORK TIMES
For all the pronouncements about the United States and China reaching a historic climate pact, the agreement they announced Wednesday does not signal a seismic shift in policies by either nation, experts said.
The United States and China should both be able to meet the stated goals by aggressively pursuing policies that are largely in place, these analysts said. For the United States, those include the Obama administration’s proposal to reduce greenhouse gas emissions from coal plants, which would go into effect in 2017. Experts said that in practice it should be possible to wring more emissions cuts from that and other climate-related measures without adding to costs.
“We think that the tools are there to meet this target,” said David Doniger, director of the climate program at the Natural Resources Defense Council.
Politics, of course, may get in the way — Republicans in Congress vowed to fight the power plant proposal even before it was introduced in June, and some, including Senator Mitch McConnell of Kentucky, who is set to become the majority leader next year, have already sharply criticized the China pact.
Policy analysts said a changing energy mix for China, including a buildup of renewable energy sources and nuclear power, had been in the works for some time. “What China is pledging to do here is not a lot different from what China’s policies are on a track to deliver,” said David G. Victor, who studies climate policy at the University of California at San Diego.
Wang Yi, a professor at the Chinese Academy of Sciences in Beijing, said experts in China had reached a consensus that the 2030 date was achievable for its targets, and that 2025 would be a more ambitious goal.
The agreement, announced during President Obama’s visit with President Xi Jinping in Beijing, calls for the United States to reduce carbon emissions by 26 percent to 28 percent from 2005 levels by 2025. That represents a significant acceleration in the rate of reduction from the president’s earlier pledge to cut emissions 17 percent by 2020.
