When choosing the best option for reducing your power bill, it is important to understand the benefits and drawbacks of two of the most popular energy sources: Wind Energy and Solar Energy.
Solar Energy
The earth does not produce energy on its own. Solar Energy creates two other sources of energy often utilized by homes and businesses: water and wind. Solar Energy is collected using various types of Solar Panels, which is then channeled into a home via "Grid-Tie" or "Off Grid" systems.
The Grid-tie systems collect solar energy and feed it directly into your electrical system through a grid-tie inverter. In this arrangement, the electric company is essentially the storer of any excess electricity collected throughout any given day. The advantage of this method is the cost savings in needing to purchase a battery bank to store the energy. If you happen to produce more electricity than you use, many electric companies will pay their customers for each extra Kilowatt Hour (KWH) of electricity fed back into their system. However, the amount electric companies pay their customers for the electricity is not typically as high as the amount they would charge you for the same amount.
Off-Grid systems are the same as Grid-tie, except they store the extra solar energy collected by solar panels into batteries. The off-grid inverters cost less, but there will be a substantial battery cost. The amount of batteries needed will depend on the number of solar panels you have. The more solar panels you purchase, the more batteries will be needed to store the energy.
Some areas of the country are more suitable for solar energy than others. Solar Panels need the direct rays of the sun in order to operate at peak efficiency. Cloudy areas such as Seattle, Washington are not going to produce as much solar energy as places like Phoenix, Arizona. While Seattle is one of the worst areas, if you were to make a line that went from Minnesota to Ohio to Maine, that area of the country fares only little better in its worst month. See a Solar Radiation map for more specific information in your area.
Wind Energy
Wind energy has the distinct advantage of being available both night and day. When the storm clouds roll in, blocking the afternoon sun, wind energy is there to pick up the slack. Interestingly, wind energy is actually produced by solar energy, albeit indirectly. As the sun's rays come in contact with the earth, some areas absorb more heat than other areas, and some areas receive more direct rays (e.g. the equator) than others (e.g. the North Pole). The warm atmosphere gases then naturally move to colder areas, creating wind.
Some areas of the country are more suited for wind energy than others. If you live in the southeastern section of the United States, wind energy is not a good option unless you live in a high elevation or near a coastline. A wind resource map can be located on the web site listed in this article.
Another important factor in determining whether or not wind energy is a good possibility for your home is whether or not you are able to place a wind turbine at a high enough elevation to produce a cost-effective amount of energy. Most guides recommend wind turbine installation at an elevation of 30 feet higher than the surrounding area. The higher your wind turbine, the more energy it is going to produce. Of course, this also means that initial installation costs will be higher as well. Overall, wind energy is a great way to reduce your carbon footprint. Just make sure your location is well suited for it.
Conclusion
It can be a very satisfying experience knowing that you are saving money and reducing your carbon footprint every time you see the wind blowing or the sun shining. With the federal government basically picking up 30% of the tab through tax credits, now is a great time to invest.
