Renewable energy is derived from natural processes that are replenished constantly. Sources include the Sun, wind, the oceans, biomass, water flowing downhill, and heat from inside the Earth.
Scientists and engineers all over the world including here in Massachusetts are developing new technologies to generate, harvest, store, transport, and use energy more efficiently.
Each source of energy has its benefits and challenges, but at its core, each technology enables renewable energy to be converted, or transformed, into electrical energy. Here, you can learn more about some of the more promising renewable energy types. To gain a hands-on sense of how they generate power, visit the Energized! exhibit at the Museum of Science, Boston.
