claim: [ subsidies for wind and solar ] add to emissions because coal-fired elec­tricity needs to be on standby for when there is no wind or sunshine.
evidence: Though in 2007 some suggested that a subsidy shift would help to level the playing field and support growing energy sectors, namely solar power, wind power, and bio-fuels., by 2017 those sources combined had yet to provide 10% of U.S. electricity, and intermittency forced utilities to remain reliant on oil, natural gas, and coal to meet baseload demand.
