WIND ENERGY

In the early 1980s wind energy really took off in California, partly because of state policies that encouraged renewable energy sources. Support for wind development has since spread to other states, but California still produces more than twice as much wind energy as any other state.

The cost of energy generated by wind power

The Cost of Energy Generated by Wind Power. The total cost per kWh produced (unit cost) is calculated by discounting and levelising investment and O&M costs over the lifetime of the turbine, and then dividing them by the annual electricity production. The unit cost of generation is thus calculated as an average cost over the turbine’s lifetime.
