Searching out alternative energy options is needed now more than ever before, because of the rising cost of oil and the threat of Global Warming. With the conditions of the World today, we all should be looking at the alternatives that are available to us. The signs of environmental changes cannot be ignored, even by those of us who are not scientists or environmentalists, yet it will ultimately depend on each one of us to make the adjustments necessary in our lifestyle habits and spending. Collectively, we can all help to save the earth from the threat of impending devastation, if we act now by switching to natural and renewable energy resources.
The three energy sources I will focus on have been around for years, and as time passes their respective technology and efficiency increases. These three energy sources are Solar Panels, Wind Turbines, and Geothermal Power.
Solar energy was first being utilized, more than 100 years ago, since the middle of the industrial revolution. Early solar power plants were built to produce steam to power the machines of factories. Around that time, Henri Becquerel discovered the photovoltaic effect. Photovoltaic is the production of electricity straight from the sun.
