User fees are charges for items like postage stamps, Medicare premiums, veterans' life insurance policies and electricity rates for power supplied by federal agencies such as the Tennessee Valley Authority.
According to the International Energy Agency, the amount of power supplied by renewables has grown only 2.5% a year from 1971 to 2011, to a modest 8.2% of total power generation in developed nations.
User fees are charges for items like postage stamps, Medicare premiums, veterans' life insurance policies and electricity rates for power supplied by federal agencies such as the Tennessee Valley Authority (nyse: TVC - news - people ).
In both scenarios, the amount of electricity supplied through the power grid is lower during peak periods, which improves reliability, reduces rates by avoiding the use of high-priced power plants during peak hours and delays capital intensive infrastructure investments needed to maintain the grid.
