Wind and Solar Power Systems

            On a national and global scale, humans have developed growing and life threatening addiction to energy in order to provide electricity and heat. As a potential solution, natural gas is highly abundant throughout the world and can help nations like the United States become less dependent on fossil fuels. Despite relentless talks of a global energy addiction, it seems that too few of actions are actually being taken toward weaning the world off of its fossil-fuel addictions. The questions involve how we interpret the term "energy crisis". Two essential questions are, Is the energy crisis really the environmental issue of safer and healthier means of mining and utilizing energy resources and how has energy crisis affected us now as well as has it been predicted to occur in the future at our global rate of resource consumption? .
             The true energy crisis is that of an ecologically sane and stable means of obtaining sufficient energy without destroying our environment. The energy crisis exists because our common global methods of obtaining energy are still primarily through fossil fuels and highly detrimental to the environment. Nuclear energy eventually creates large quantities of radioactive waste and can contaminate the surrounding environment (Macfarlane). Burning coal creates massive amounts of carbon dioxide in the atmosphere causing illness and aiding global warming. Burning fossil fuels like oil creates green house gases and mining oil contaminates the ground and wildlife. Burning natural gas also creates greenhouse gases. There are two types of solar energy systems; solar thermal and photovoltaic. They both capture the natural energy from the sun, but they work in different ways. Solar thermal systems absorb the natural energy from the sun to generate heat. Similarly, solar photovoltaic systems absorb the natural energy from the sun, but they then convert this energy into electricity.

1. The Financial Benefits of Solar Power

The problem is that installing a solar system is very expensive. A professionally installed solar system designed to power everything in your house except the heating/cooling system can cost anywhere from $10,000-$30,000. ... Wind power is not reliable enough to provide all your electric needs. ... If you supplemented your solar with wind power, you wouldn't need as many cells. ... The point is, that while there is labor involved, and the quality is obviously not going to be as high as a professionally built and installed system, it is possible to have solar power for about a tenth of...

3. Concepts of Sustainable Energy

The wind power industry grew $25 billion last year and provided more than 10,000 megawatts of wind power in Texas alone to support 30% of the US electricity (Henry). With large amounts of wind power being produced, wind energy undercut power prices by being 14% cheaper than a new coal plant, and 18% cheaper than a new gas plant and nuclear plant. ... Aside from wind power, another source of electricity is being provided by hydropower. ... The second way to generate electricity is with solar thermal-electric systems, which produce steam that spins a turbine connected to an electrical generator....

"In the last few decades, technological leaps and the scaled-up production of solar panels have made solar power dramatically less expensive. ... The American Wind Energy Association, a national trade association for the U.S. wind industry states that, "The purchase and installation of a system large enough to power an entire home costs, on average, $30,000, but the price can range from $10,000 to $70,000 depending on system ...

5. Resurgence of Wind Power

The term "Wind Power" describes the process by which wind energy is transformed into mechanical power or electricity. ... When the U.S and Denmark had success with wind power many countries began to test and research wind power including Russia, Germany and Spain. ... Fears of shortages and over dependence pushed the formation of Energy Research and Development Administration (ERDA) that was responsible for starting the Nation's solar energy program (Krenz,1980). Wind energy was one program that was considered by the solar energy program because wind power is non-depleting, nonpolluting,...

6. Alternative Energy

Wind is more reasonable because wind can be generated twenty four hours a day, whereas solar energy can only be produced during part of the day (Sheahan 67). Wind has a very strong power relationship; the amount of power that is accessible from wind is directly related to the area that the wind turbine's rotors take up and the cube of the wind's velocity. ... Wind turbines are the perfect solution for alternative energy: there are no major technology barriers that stand in the way right now and there are systems which are cost competitive with other methods of electrical systems. ...

7. The Winspire Wind Turbine

Besides solar energy, wind energy is a free and limitless power source. ... Its known that in the past, win power was captured and controlled through the use of sails for the powering of ships. ... Also; there are a few arguments that say the Windspire wind turbines are not suitable for commercial use because they can't generate as much power as the regular propeller wind turbines. ... At wind speeds higher than 27 mph the redundant electronic braking system will engage as a safety feature. ... For the regular propeller wind turbines, choosing a place to install the system can be to...
