To see why, consider that goal of 100% renewable energy. It makes solving climate change seem deceptively easy.(例证)

Carmakers may hit their goal of annual sales of 10m electric vehicles in a decade, but battery-powered road haulage, shipping and aviation are dreams. A much-quoted claim that America could rely on wind, solar and hydro alone for its electricity has recently been witheringly criticised by a group of respected academics.
