There is no convincing proof that utility-scale wind plants reduce fossil fuel consumption or CO2 emissions. Although there are are a number of reports claiming gains can be made that will combat climate change, free us from fossil fuel “addiction,” provide energy independence and needed 21st century industrial development, such reports are not substantiated by definitive and comprehensive analyses.
To determine the actual effects will require long-term time series, at intervals significantly less than one hour, of wind production and fuel consumption due to fast ramping of fossil fuel plants to compensate for wind’s volatility in an electricity system where wind represents approximately at least 1-2% of production.
As opposed to wind proponents’ claims, studies based on actual experience with wind integration are emerging that demonstrate the fossil fuel and CO2 emissions gains are not valid.…
