    Renewable-energy generation costs are falling like photons onto a solar panel. By 2020, it's expected all types of renewable-energy generation will be able to compete with fossil fuels on cost. That's right: saving our environment will actually save electric utilities some money, too. DON'T MISS: Two-thirds of world's new energy capacity in 2016 was renewable: IEA The cost of generating electricity with onshore wind has fallen by about 25 percent since 2010, according to a new cost analysis from the International Renewable Energy Agency (Irena) During that same period, solar power generation...

    U.S. regulator rejects coal, nuclear bailout, says renewable energy may double by 2020

    For much of last year, U.S. Energy Secretary Rick Perry pursued a plan that, in essence, would prop up the financially challenged U.S. coal and nuclear industries. His proposal, submitted to the Federal Energy Regulatory Commission last fall, provided financial subsidies to electric-generation...

    The purchase of an electric car that plugs into the power grid to recharge its battery often gets drivers thinking about the source of their energy. We haven't seen data from recent years looking at the overlap between electric-car drivers and home solar panels. But early analyses in California indicated as many as four in 10 electric-car drivers were already using or considering the addition of home solar panels to generate electricity.
