Besides hydroelectric power, some of the other alternatives that are being utilized today include sources such: wind, geothermal, wave/tidal, hydrogen, bio-fuels, and, of course, solar. Scientists are working all the time to improve the technologies of all of these alternatives in order to create a world in which we can comfortably live without depleting all of the earth’s non-renewable resources.
Solar Power captures the sun’s energy to provide and heat and electricity. It is used on a large scale, to capture and transmit power to whole communities, and small scale, to power a single home. Jobs in this area include:

Geothermal Energy utilizes heat from the earth for many purposes such as heating buildings, melting snow, and generating electricity, if it is hot enough. Jobs in this area include:
Wind Power uses the amazing power of the wind for energy, through modern windmills that generate electricity. Windmills have been used for centuries to grind grain and pump water. Today, giant wind turbines can generate much of the electricity for large communities. Jobs in this industry include:
