Alternative Energy Souces For Lee County Essay

Tidal Stream Systems can make use of the kinetic energy from the moving water currents to power turbines, in the same way that windmills use moving air.However, the United States department of Energy is developing an energy source called the fuel cell that will utilize hydrogen and reduce dependence on foreign energy sources.The Random House Unabridged Dictionary defines biomass as energy, organic matter, especially plant matter, that can be converted to fuel and is therefore regarded as a potential energy source.As the cost of wind energy continues to decline, Lee County will be able to utilize this source of energy more efficiently.Hydrogen by itself is an energy carrier not an energy source.

Taking a Look at Hydroelectric Power Essays

So what exactly is water energy?The water behind the dam flows through an intake and pushes against blades in a turbine, causing them to turn.There have been intense debates on whether this source of energy is worth using up the water from the lakes and rivers, something that is important to protect the animals and plants.A typical hydro plant is a system with three parts: an electric plant where the electricity is produced; a dam that can be opened or closed to control water flow; and a reservoir where the water can be stored.Energy sources using water have been around for thousands of years in the form of of water clocks and water wheels.In addition to supporting life water has been used for centuries to power saw mills that would gene...

The Significance of Geothermal Heating

However, this source of power is not an ideal long term plan for development as it is prone to a lot of environmental factors such as decrease of durability and water drought.Moreover, even if the US uses thermal energy beneath earth as its sole source of primary energy, it would only be consuming a very small fraction of it.This type of heat energy is also renewable through the water cycle where the heat from the earth’s surface evaporates water and subsequently brings it back to earth in the form of rain.According to the report, another source of power are water dams.Once the water is pumped to the power plant,  the pressure decreases, causing the water to be converted or “flashed” into steam to power the plant’s turbine.

Renewable Energy

Solar energy is known as the most plentiful and cleanest renewable energy source available (CanSIA, 2011, para.1).Because water is eight-hundred times denser than air, this means that even a slow flowing stream can still produce a large amount of energy (“Types of Power,” 2014, para.6).Hydropower, also known as water power, comes from the energy of falling and running water, which can be harnessed for useful purposes (“Energy Source: Hydropower,” n.d., para.National renewable energy markets are expected to continue to grow in the coming decade (REN21, 2014).This shows that renewable energy like wind power, hydropower, and solar energy are only going to continue to become more popular and be widely used throughout the world.There are many...

Ocean Turbines

The World Energy Council (WEC, 2000) has actively pursued an alternative for fossil fuels for at least the past 20 years but this is slow moving since research has been so limited with sustainable energy and there is little historical evidence to truly back up its reliability because published data on Offshore Wave Energy Conversion devices too often provide insufficient data to assess the true accuracy of the energy they are collecting (Ocean Energy, 2008).They are differentiated by either extracting the energy from waves moving across the surface of the water or from the pressure fluctuating under the surface of the water (Abu Sharkh, Morris, Turnock, Myers, & Bahaj, 2002).What this example shows us is if the water current research...
