Big boost to US renewable energy could cost nothing

Switching a large fraction of US energy to renewable sources by 2025 could involve no increase in cost, says an independent US think thank, as long as current price trends hold firm.Renewable sources currently provide about 6% of the energy used in the US. The new RAND report concludes this could be boosted to a total of 18% by 2025, equivalent to 25% of electricity and motoring fuel, at no extra cost. The provisos are that the price of renewable energy continues its downward trend and that predictions of future oil prices are roughly accurate.
