Juliet Davenport: founder and Chief Executive of Good Energy

It was at university that I was first awed and concerned in equal measure by the wonder and fragility of our climate system; but I found it difficult to see how I could make a difference. I decided to take positive action by setting up Good Energy – a green energy supplier. The aim was to give people an opportunity to do something about climate change. We wanted to offer a solution that could appeal to people, to say ‘yes, this is big and quite a scary issue but you can do something about it'
