In this paper the author examines the sources available to create power and
electricity. He looks at how technology is used
to take advantage of the forces of nature available. The paper highlights how up until recently only the power created by falling water has been explored and used successfully in a number of applications. Sun, wind, waves, rivers, tides and the heat from radioactive decay in the earth's core are all looked at as being renew ables, in other words they give continuous sources. The paper concludes with a look at all of the
environmental aspects of using these renewable sources, the arguments for and against each one including the aesthetic issues that arise. Introduction Solar Energy Wind Energy Rivers Geothermal Relating Renewable to Base-Load
