UNITED STATES OF AMERICA – ENERGY: See renewable energy in America. 

‘America’s shale revolution has turned the country into the world’s biggest combined producer of oil and gas,’ (The Economist Special Report on The geopolitics of Energy, March 17th 2018). This means ‘the real threat to coal is gas, which fracking has made cheap and abundant,’ says The Economist. ‘Coal remains America’s second-most widely used energy source, generating 30% of American electricity in 2016, more than nuclear (20%) or renewable sources (15%). Natural gas, however, generated 34%, a share that has risen as coal’s has fallen—by close to a third from 2011 to 2016. Renewable energy is also getting cheaper and more widespread. Since 2010 the share of domestic energy generated by renewables has grown by nearly 50%, (‘Holler promises, The Economist 16th December 2017, p.38).
