Not exact matches

But he wholly fails to explain what the implications of the variability problem is (the need for overbuild of generation capacity and expensive / unfeasible large - scale energy storage), nor whether, if an effort is made to deal practically with these problems in real national electricity grids, the «increasingly cheaper» renewables will ever become cheap enough (when all relevant real - world factors are considered) and reliable enough (without natural gas «backup»), to actually substitute for and displace fossil fuels (or nuclear) at the scale required.

The added costs imposed by intermittent energy sources like wind energy include the displacement of lower cost generation (e.g., natural gas), requirement of dispatchable backup generation, reduced capacity factors for conventional generation, increased electric price volatility, and decreased system efficiency.
