We all know energy can come from the wind and the sun, but there's a plentiful renewable resource covering more than 75% of the planet that you might not have thought about: our water! The movement of the ocean's waves, tides, and currents carries energy that can be harnessed and converted into electricity to power our homes, buildings and cities. The energy available in this moving water is called kinetic energy. Scientists and engineers are learning to capture clean renewable ocean power using marine and hydrokinetic technologies.
