There are compelling economic and environmental reasons for America to immediately move from fossil fuels (coal, oil or natural gas) to renewable energy. Electricity from onshore wind, solar and hydropower is cheaper to generate than from any form of fossil fuels.
New technology is continuing to drive down the cost of power from renewable energy. Fossil fuels are not renewable resources, which will eventually be depleted in the not too distant future. As fossil fuels are depleted the price of the commodities will dramatically increase. The future cost for any form of fossil fuel will only increase. In my opinion, there is no economic or environmental reason for America not to move from fossil fuel to renewable energy.
