Deborah and Fliss meet Alice Delahunty, President of National Grid's transmission service. They find out what part renewables play in today's electricity supply and exactly when we can expect a 100% green grid.

And if you think solar panels are only for the rich, find out about the Welsh social housing provider installing panels on hundreds of tenants roofs.

Presented by Deborah Meaden and Felicity Hannah.
