Welcome to this course on renewable energy. With it we hope that you will learn about the various forms of energy that you come in contact with every day such as light, heat, and especially electrical energy, which is the main focus of this course. Energy is involved in every action that occurs in the universe, including all physical actions like the sun shining, the winds produced by the weather, the actions of the tides and the growth and decay of plants and animals. All of these physical actions can be converted to electrical energy. The experiments in this course will allow you to harness and analyze energy produced by sunlight and by wind.

We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
