Renewable energy

OVO's renewable electricity comes from all these, plus geothermal sources and biomass. However, no matter how many sources an energy company uses to generate power, once it's on the national grid it all mingles together, renewables with non-renewables.

So no electricity provider can promise you that all your energy comes from a renewable source. Instead, energy companies can use a Renewable Energy Guarantee of Origin certificate from Ofgem, which shows how much renewable electricity they've bought and sold to customers.
With OVO Greener Energy, although we can't guarantee that all the electricity is from renewable sources, we can show that for every unit you use, we've bought the same amount of renewable electricity.
