To see how closely water and energy are linked, you only have to look at the west coast of the US, where four years of severe drought have led to historically low levels in water reservoirs, forcing some hydroelectric plants to shut down or cut production.
It’s little wonder, then, that new micro-hydropower technology that allows cities to generate electricity from the water running through their pipes is gaining worldwide attention.
