Gas-fired plants have stepped up to fill energy demands after a weather phenomenon sent wind power generation plummeting in the UK and Germany.
The "Dunkelflaute", meaning "dark wind lull" refers to a period in which wind speeds drop dramatically, causing turbines to produce little or no electricity.
The Telegraph reports that on Tuesday wind farms could only meet 3-4% of the UK's power requirements during the morning and evening peak times.
Instead, gas-fired plants met around 60% of the demand while the remainder was covered by nuclear and biomass power plants, solar farms and imports.
A similar trend happened in Germany, with the Telegraph reporting low wind speeds led to wind farms generating just 7% of their nameplate capacity.
German coal-fired power plants met 30% of the power demands with gas and solar farms also contributing to make up the shortfall.
