Renewables to make up half the UK’s power supply

Wind turbines towering over the landscape

When they say ‘flexible power sources’ they mean the ones that are needed when unreliable renewables have largely gone to sleep, for example at night or when it’s not windy. The costs of running such a dual system or the consequences of power shortages, especially in winter, are not mentioned, although they admit that there will be “entire weeks and months” where solar and wind will produce “little energy”. It all sounds unreal.

Renewable energy will account for more than half of the UK’s power supply by 2026, according to a new study, reports Utility Week.

The report by Bloomberg New Energy Finance and commissioned by Eaton and the Renewable Energy Association, claims there will be a “significant acceleration” in the shift to renewable sources over the next 20 years and that this move will create new opportunities for new flexible power sources.

By 2040, almost two thirds (63 per cent) of power will be generated from renewable sources, according to the report and at “certain times” wind and solar energy along could meet total power demand in both the UK and Germany.

But the report also warns that at other times, there will be “entire weeks and months” where solar and wind will produce “little energy”.

It adds high levels of variable generation will create a “very challenging environment” for baseload technologies, such as nuclear and coal and the total back-up capacity needed by 2040 in this country will be much the same as it is today.

According to the study, 70GW will be needed in the UK and 97GW will be needed in Germany in 2040 to meet peak demand during periods of low wind and solar generation.
