Renewable energy sources seem to have been given an unexpected boost. Around 40 per cent of the electricity generated in the UK on Sunday 5th March came from wind farms, with nearly a fifth being provided by solar energy. This was due to the unusually sunny day, says the National Grid ESO carbon intensity tracker.

These conditions have meant that renewable sources generated more than enough energy to cover the country’s reduced needs. Green supplier, Octopus Energy, even paid some customers to use energy during the day, using a scheme that has previously only been available during the night when demand is very low.

“In most economies that have taken strong confinement measures in response to the coronavirus – and for which we have available data – electricity demand has declined by around 15%, largely as a result of factories and businesses halting operations,” Dr Fatih Birol, Executive Director of the International Energy Agency wrote in a blog post.

“In this way, the recent drop in electricity demand fast-forwarded some power systems 10 years into the future, suddenly giving them levels of wind and solar power they wouldn’t have had otherwise without another decade of investment in renewables.”

He went on to explain that this increase in renewable energy usage could even help some countries figure out how to deal with the drop in power that comes from the sun setting or a strong wind dying down. Previously, these kinds of fluctuating energy sources have proved challenging for those who work to keep our lights on. Managing them more ntelligently by shutting off solar panels at midday when there is more electricity than usual and slowing down wind power as demand decreases at night are just some options Dr Birol suggests.

These new findings have also put the spotlight on more reliable and often neglected sources of green energy, like hydropower, which are essential to making sure we have a consistent supply of energy. In exceptional situations like the current pandemic, where a fluctuation in energy supply could put lives and employment at even greater risk, this is particularly important.
