Globally, energy production and use is responsible for around 75% of the world’s carbon emissions, with around a third of that on electricity and heat alone. To tackle climate change, we need to get more energy from renewable sources, so this week we’re taking a look at some of the more surprising ways people have come up with to harness clean energy from the world around us.

In the United States, we see what happened when a group of concerned mothers forged a surprising alliance with a gas company, and worked together to get clean energy from the ground beneath their feet.

In Madagascar, we meet the grandmothers bringing solar light to their remote villages, plus we visit Wales, where an innovative new technology is harnessing power from the tides – by flying “kites” underwater.

People Fixing The World from the BBC is about brilliant solutions to the world's problems. We'd love you to let us know what you think and to hear about your own solutions.
