Energy storage: making 100% renewable power a reality

In a future powered by 100% renewable energy, we're going to need to be able to call on green electrons when we need them. Given that we can't make the sun shine and the wind blow on demand, where is this flexibility going to come from? Energy storage might just be the solution we've been waiting for.

Making Green Energy Greener

We look to a future where wind & solar farms are buzzing with biodiversity, exploring new ways for renewable sites to help the planet.

How we're weathering the storm in Texas

Texas experienced a massive power grid failure affecting 90% of the state. People were stranded in unbearable conditions: loss of heat in below freezing temperatures and lack of access to water, food and other essentials.

Michael, CEO of Octopus Energy US, explains what happened in Texas, how we're protecting customers through the energy crisis, forgiving energy bills from this unprecedented event, and why renewables are the answer to a more resilient grid.

Where does our 100% green electricity come from?

Meet some of the solar plants and wind farms we buy energy directly from, and find out about some other ways a supplier can can fulfill their 100% renewable promise.

The Answer, my friend: now is the time to lean into wind

It would appear my email of Thursday was not well received in the Clark household.

“If it wasn’t miserable enough being told that I have to spend the next month at home,” Mr Clark writes “now I have ‘Pete’ from Octopus Energy emailing me and asking if I would mind terribly turning off a few appliances between 4.30pm and 6.30pm.”

I’m delighted to learn Mr Clark is a customer of Octopus Energy – thank you. The email in question was an invitation to take part in a smart energy trial we were running.

This experiment offered everyday customers free electricity in return for halving their energy use during two specific hours.

Climate change and land: Understanding the IPCC's latest report

The ability of the planet to sustain human life is now seriously endangered. Climate change caused by fossil fuels and food production as the planet warms inexorably means we must take action and change our behaviour. The warmest ten years since records began in 1884 have all occurred since 2002.
