As we strive to deflect the United States’ dependence on foreign oil sources for energy, the question begins to arise as to whether there is truly an energy source which is completely renewable. A renewable energy source is defined as one that is continually naturally replenished, and the first forms of this energy that come to mind are typically solar and wind energy. As technology develops in both of these fields the fact remains that there are costly modifications to be made in the industries currently supplying our energy. Whether these be modifications of existing systems to coordinate with new energy sources, or construction of entirely new systems to harness and distribute the alternative energy sources, the cost considerations must include the potential longevity of the energy source.

For example, we consider the sun to be a permanent source of energy, and indeed it is for all practical purposes. The question of it’s usability becomes an issue when considering the climate changes that are occurring all over the world. While it seems that the greenhouse effect may actually work in favor of solar energy harnessing, we must also consider increases in air pollution, which disrupt the collection of solar energy, as well as the patterns of intense rain and snow which make solar cells inoperable until weather conditions are cooperative.

The use of wind energy is the fastest growing industry in renewable energy sources, and can also be dramatically altered by the effects of weather and the greenhouse effect. If the wind direction changes, how efficient will the fields of wind turbines continue to be? Will constant changes in wind shear cause the components of the turbines to age prematurely? Is it possible for the wind and weather patterns to change so abruptly that the wind farms will be rendered useless? Can we predict the life expectancy of these machines and plan ahead for the possibility of forced relocation? Of course, these are all questions which should be addressed in the planning phases of staging wind turbine farm locations.

As scientific research technology is beginning to focus more on wave energy harnessing, again we must consider the shift in weather patterns due to global warming, and the effect it may have on the oceanic levels and the directions of the currents. While the ecological impact of current redirections could be detrimental, a compounded issue with loss of energy resources would be devastating. Dramatic rises and drops in water levels due to polar ice cap depletions could result in entire reservoir dams being under water.

The questions seem extremist and paranoid, but considering the dramatic shift in weather patterns in the last thirty years, it seems evident that the climate can rapidly change. In planning for a future where the nation is independent from foreign oil and relies on domestic sources of alternative and renewable energy sources we must prepare for the contingency that dramatic shifts in weather may negatively impact our harvesting of what currently appears to be an unending renewable energy source.

Getting or building a wind power generator for home use is quickly becoming an attractive option for many environmentally conscious homeowners. Alternative energy sources are looking quite feasible in helping to alleviate both environmental damage and fuel shortage related to the use of fossil fuels. If we manage to develop these budding fields properly, we may eventually wean ourselves off of our reliance on coal, oil, and gas. This will not only stabilize our power generation, but also result in many benefits to the environment as we use renewable, green ways of making energy. Thus, the need for a wind power generator for home use.

These electricity generators are becoming more and more commonplace as people install more of them both on large and small scales. They are machines that can convert the natural breeze-induced mechanical movements into electricity. Thus, they only need this force of nature to produce energy, which is free, essentially unlimited or renewable, and all natural. This basic concept of harnessing the energy all around us is what lies behind any good renewable energy source.

Some background on the concept behind using a wind power generator for home use would be useful to have. Generators work by transforming physical motion, usually rotation, into electricity using strong permanent magnets. Turbines then work on the same essential principle, using natural flows to turn blades, which then produce electricity in conjunction with magnets. Both direct and alternating current may be produced by generators (for AC, the term used is usually alternator instead of generator, but the concept is basically the same). The electricity produced can then be wired to devices for immediate usage, stored in batteries, or even wired back into the power grid for other users.

Most renewable energy sources require a higher capital outlay than conventional fossil fuel power generation. This is because the technology for these new energy sources is much younger and less understood and developed than the older technologies. However, as interest in these sources continues, technological and engineering developments should make costs more manageable. In fact, at present, many systems are already being made available for residential use. This is why it is relatively easy to get your hands on a homemade windmill/turbine.

Of course, harnessing the breeze would not necessarily be efficient for every single home and location. There needs to be, first and foremost, enough available space for the turbine. The amount of space and clearance required varies from setup to setup: some can be mounted on roofs while others need freestanding towers. Remember that the strength of this force of nature would also not be constant throughout the year, meaning other sources must also be used. Getting a wind power generator for home use is still a great, green idea, however.
