With the earth's precious natural resources being used up and the pollution from our great use of fossil fuels, many nations and communities have turned to the use of an alternative energy sources. Among those alternative energy sources is the use of tidal waves and currents to generate electri...

The first question, which I must ask in order to write this essay, is, what is energy? Energy gives us the ability to do thing. Everything in the world needs a supply of energy, and so energy is used to make things work. The word energy is taken from the Greeks and means "the work within"...

Our everyday actions can help to bring the goal of environmental sustainability closer too reality. Ecosystems use the sunlight as their source of energy. We too can harness the sun's energy and promote sustainability in doing so. One simple way to do this is to simply open our window shades...

One of the earliest ways to harness power is to use the powerful flow of water. On September 30th, 1882, in Appleton, Wisconsin, the first ever dam was built. Since then, over 2,044 billion-kilowatt hours have been produced each day, worldwide. This source of energy is being used more and more ...

If I were a Secretary in the Federal Government, and needed to implement policies to curb global warming, I would do all that was possible in my powers to ensure the policies were sensible, and really made a difference to the serious problem of global warming, because we only have one plan...

Impacts of Wave Energy Visual Impact - Depending on where the conversion facility is placed the visual impact can range from high impact close to the shoreline to a much smaller impact when the facility is placed further from the shoreline. Hydrodynamics - effects on wave climates due to convers...

Wind Turbine Technology Since early history, people have been harnessing the energy of the wind. Wind energy propels boats along rivers, simple windmills, and pumping water as early as 5000 B.C. New ways of using the energy of the wind eventually spread around the world. By the 11th century, peo...
