Harnessing Solar and Heat Pump Technologies

As the founder and CEO of Octopus Energy, Greg Jackson knows more about Britain's household energy than almost anyone else. 
In this interview with This is Money's Simon Lambert, he explains why bills are still so high, what we can do as a nation to try to bring them down - and the future of household energy.
Greg explains what people need to know about solar panels, heat pumps, electric cars and agile energy deals - and what we can do for those who don't want any of those things.
He also discusses an idea that he is passionated about, making renewable energy cheaper - and sometimes even free - for those nearer to the source, which he believes could help both individuals and businesses - and attract big technology firms to the UK.
