    SOLAR AND WIND BEAT COAL, GAS ON PRICE

    Solar and Wind Energy Start to Win on Price vs. Conventional Fuels

    Diane Cardwell, November 23, 2014 (NY Times)

    The cost of electricity from wind and solar resources in some markets now beats coal and natural gas and the trend is accelerating, especially in the Great Plains and Southwest. The price of solar has fallen 70% since 2008 and the Midwest PPA price of wind fell over 50% in the last 5 years. Austin Energy recently completed a power purchase agreement (PPA) for solar at under $0.05 per kilowatt­hour. In Oklahoma, Grand River Dam Authority announced a PPA it said would save customers an estimated $50 million and American Electric Power tripled its wind acquisitions on the strength of low bids. Investment banking firm Lazard’s most recent levelized cost of energy (LCOE) analysis shows utility-­scale solar energy is as low as $0.056 per kilowatt­hour with subsidies and about $0.072 unsubsidized, wind is as low as $0.014 per kilowatt-hour with subsidies and $0.037 without, natural gas is $0.061 per kilowatt-hour, and coal is $0.06 per kilowatt-hour. The LCOE fails to include fossil fuel health and societal impacts, the economic impacts of fossil fuel price volatility or the increasing costs of climate change. For renewables, it fails to consider the costs to integrate variable resources into power markets. click here for more
