The growth of the renewable energy industry in the U.S. is participating in the decline of the countrys coal industry, with a recent report by the Carbon Tracker Initiative revealing a sector that is in terminal decline.
According to the report, the U.S. coal industry has lost 76% of its value in the past five years, with 26 leading companies going bust since 2012 and 264 mines closing between 2011 and 2013. Peabody Energy, the worlds largest private coal company, has lost 80% of its share price since 2011.
Faced with a one-two punch of stricter environmental regulations and the plunging costs of shale gas (prices of shale have fallen by 80% since 2008), the coal industry has been further injured by the rise of the renewable energy sector, which now accounts for 4.1% of U.S. electricity generation. Gas, powered by the shale revolution, is now 8.1% of the U.S. grid.
"Gas took the legs out from the sector and regulations from the Environmental Protection Agency (EPA) really held it down," said Luke Sussams, co-author of the report.
Last year, as part of the EPA regulations, President Barack Obama announced that carbon emissions from coal power plants must fall by 30% by 2030 in a ruling that is likely to further diminish coals influence on the U.S.s energy market.
The concept of "stranded assets" whereby companies hold increasingly worthless reserves of fossil fuels as governments and international bodies pour greater environmental regulations into their energy mix was raised by Carbon Tracker in its report, with Sussams adding that Obamas ruling "proves that the stranded assets concept doesnt rely on international regulations".
The U.S. coal industry had been banking on a future that involved large-scale coal exports to the markets of China and Australia, partly as a means of guarding against domestic regulation and a growing hostility in the U.S. to dirty fossil fuels.
However, Australias own coal supply chain as well as those from South Africa and Indonesia has upset these plans, with U.S. coal more expensive than many rival producing nations. In turn, both China and India have lowered their coal consumption in recent years (Chinas consumption fell 3% in 2014) as both of these nations have increasingly embraced solar PV and other forms of renewable, further undermining the U.S. coal industrys strategy for survival.
"The roof has fallen in on U.S. coal, and alarm bells should be ringing for investors in related sectors around the world," added Andrew Grant, the reports other co-author. "These first tremors are among the clearest signs yet of a seismic shift in energy markets, as high carbon fuels are set to be increasingly outperformed by lower carbon alternatives."
In contrast, figures from the U.S. Energy Information Administration (EIA) reveal that the amount of large-scale solar PV deployed in the U.S. doubled in 2014, growing by 102% between 2013 and 2014.
The entire U.S. solar industry including residential and commercial scale PV grew by 30% last year, with GTM Research confirming that around 6.2 GW of additional capacity was added a figure that accounted for 32% of all new generating capacity in 2014.
