Hundreds of millions of people don’t have access to electricity. But all over the world, people are joining forces to provide a home-grown solution — by setting up their own “microgrids” using renewable energy.

We meet the Kenyan man who got so frustrated waiting for his village to be connected to the national power grid that he built his own hydro power station. Using scrap materials and a bicycle wheel he made enough electricity for his own household and many others in the community.

We’ll also hear from Bangladesh where individual households with solar panels on their roofs have formed a local network. They sell any spare power neighbours who don’t have the panels.
