Does the moon hold the key to the earth’s energy needs? Tidal power is the only renewable source derived from the moon. Now there is an extraordinary array of devices promise to unlock this vital energy potential. The ocean energy sector is frothing with ideas, with hundreds of companies developing an extraordinary array of devices and backed by billions of dollars of investment. Among the serious contenders tapping rapid tidal flows are 12 metre-wide underwater kites that soar and swoop. A coalition of 25 ocean-faring nations, called Ocean Energy Systems, estimates a global potential for wave and tidal energy of 750GW by 2050, almost twice today’s global nuclear capacity. The EU projects 100GW in 2050, providing about 10% of the bloc’s electricity.
