All the green electricity in this tariff comes from our own windmills. It's a growing component as we keep building more windmills.

It's topped up with ‘brown’ electricity which we buy from the wholesale market. This reduces each year as we build more of our own green. And we price match New Energy to the standard tariff of all the regional suppliers - so switching to New Energy should not cost you any more.

This tariff has the same component of our own green electricity as our New Energy tariff, but is topped up with somebody else's green electricity making it a 100% green tariff. You still get the same commitment from us to build new sources of green energy.

New Energy Plus comes at a small premium, around £20 more per household per year because it's topped up with green energy that we have to buy in. There's not enough of it to go round (the UK only has 6.6% renewables), so it costs a little more.

For the ultimate green home why not switch your gas to Ecotricity's Green Gas too. Just as we turn electricity bills into windmills we're now going to turn gas bills into gasmills.

To sign up for Green Gas you first have to sign up to one of our electricity tariffs above.
