Comparison of Lifecycle Greenhouse Gas Emissions of

Coal fired power plants have the highest GHG emission intensities on a lifecycle basis. Although natural gas, and to some degree oil, had noticeably lower GHG emissions, biomass, nuclear, hydroelectric, wind, and solar photovoltaic all had lifecycle GHG emission intensities that are significantly lower than fossil fuel based generation.

Wind turbine power coefficient - definition and how it's used

As explained in the page on wind turbine efficiency, the power coefficient should only be used to compare the performance of wind turbines. Cp has no relationship to the efficiencies of other electrical power sources, such as solar, gas-turbine, a coal-fired steam plant, or any other non-wind driven system.
