Energy and environment

Back when OVO started out, our ambitions were to be better, simpler and greener than traditional energy companies. And as we’ve grown, our sense of responsibility to people and planet hasn’t diminished, and neither has our passion for the science behind the energy we supply.

In this section of OVO Answers we talk about all things energy and environment – from sustainability to science!  

All those energy questions answered

Have you ever wondered what energy is? Where does it come from? What’s electricity? And what about nuclear power? Our in-house experts have been working hard to demystify all things energy in an accessible way – ideal if you're helping with the kids' homework (or just feeling curious).

OVO and the environment

As an energy company, we believe we have a responsibility to consider, and where possible, reduce our environmental impact. We do this in a number of ways, including our historic support of rainforest charity Cool Earth. There’s lots of info about that, plus other ways we’re working  hard to be greener – like providing at least 33% renewable electricity as standard. 

Doing the right thing

There’s lots of handy information to help you do the right thing too. From info about climate change, carbon footprints and recycling, through to our overview on energy efficiency, it’s all helpful stuff.

Cool Earth

OVO started working with rainforest preservation charity Cool Earth back in 2011. Together, we’ve saved an impressive 100,000 acres of rainforest. There’s info in this topic about who Cool Earth are and why we chose to work with them.  

We Dig Trees – do you? 

I Dig Trees is a programme OVO runs on behalf of our Greener Energy plan customers to plant 157,000 trees and improve over 2,000 green spaces across the UK. There’s lots of info about this exciting volunteer programme, including what kind of trees we’re planting, why we’re on a planting mission, and who’s involved.
