Fahrenheit 100: could this be the summer Britain wakes up to climate change? | Michael McCarthy

How blockchains can empower communities to control their own energy supply
As the cost of solar panels, wind generation and battery storage falls, individual households and consumers are increasingly generating their own electricity, becoming less reliant on the power grid. This has led to energy systems becoming increasingly decentralised, which helps shift market power from large utility companies to individual "prosumers" – consumers who produce their own electricity.
