Whether it’s the wind, sun or tidal waves, the Earth provides a spectrum of power sources to sustain industries, homes and individuals. Researchers and environmentalists have been pushing for clean energy, as well, contending with the rising threat of climate change.
These groups have also been trying to find innovative ways to capture the Earth’s energy so more communities can participate in the clean energy movement. Though they’ve started to gain momentum, petroleum, coal and natural gas still account for much of the world’s energy supply.
There have been promising innovations in recent years, however. An increasingly researched renewable resource is called ocean thermal energy conversion (OTEC), in which the sea’s temperature variations are used to produce power. Utilizing this heat could prove to be a great achievement, given that the ocean covers two-thirds of the Earth’s surface.
