Harnessing the vast power of the oceans' waves has recently gained popularity as a form of renewable energy that does not contribute to global warming. Seventy percent of the world's electricity needs are met by burning fossil fuels such as coal or natural gas, and these methods generate vast quantities of greenhouse gasses. Hydropower has long been considered a renewable alternative, but the current technique for harnessing that power, namely damming rivers, can be extremely damaging to ecosystems, and nearly all of the suitable locations in the world have already been tapped. Now scientists and engineers are learning to harness the unending power of ocean waves, promising electricity generation with minimal environmental effects. None of the current wave power technologies create greenhouse gasses or pollution.
