Thank you for downloading this programme. In this edition of the bottom line, we're discussing renewable energy, getting power from the sun, the wind and from cheese.

Hello and welcome to the programme. Oil prices are low, shockingly low at the moment, so we're going to be a bit countercultural today by looking at non-oil energy,

the renewables sector. Now, those low oil prices make the economics of renewables more awkward

than they might have been, but with the Paris Summit late last year nudging the world to a non-carbon

future, understanding the renewables business is more important than ever. My three guests

are all from green energy firms, so let's meet them now. And first up is Juliet Davenport,

founder and chief executive of good energy, which sources 100% of its electricity from renewables.

You sell it to the public, Juliet. But where does your

renewable energy come from? So it comes from various sources across the UK. We work with about

1,000 independent renewable generators. About 50% are wind powered, 20% solar, 20% biofuels and 5% hydroelectric

power. In what way am I by being your customer helping

renewable energy? The more customers we get, the more renewable generators we have to find

contract with. We actually invest ourselves as well. So 25% of our power comes from our own

renewable generators. Just tell me about the people you buy from.

You call a lot of them independent renewable suppliers.

So they're kind of wide range.

One of the examples is Weike Farm cheeses.

When they wash down the dairy every night, when they make the cheese,

that they then anaerobly digest it.

It creates a gas and they generate power.

That's one of our generators.
