Renewable Energy – Wind Power

Sunday, June 28th, 2009

Wind power is the useful form of energy that can be obtained from wind renewable energy. Wind power can be defined as renewable wind energy that has been converted to useful electrical energy. A way of harnessing wind renewable energy is by using wind turbines to produce electricity. Wind turbines have blades that rotate to convert the wind renewable energy to electric energy by means of an electric generator incorporated within the wind turbines. For commercial use, large amount of electricity needs to be generated which can be achieved by installing wind farms where a number of wind turbines are used together.

The use of wind renewable power has been known for a long time. This alternative energy source was used in windmills to pump water or to grind grains.

There are a lot of advantages of wind power. The main benefit of wind renewable power is that it does not cause pollution. Any types of chemical processes are not required when wind power is used and so no harmful by-products are left over that can contaminate the environment and thus degrade it. Wind power is a renewable energy source and so we can never run out of it. Using wind renewable power does not emit any global warming gases. Also it is a cost effective way of generating electricity.

There are some disadvantages also of using wind power. The use of wind turbines causes noise pollution. Also wind farms require a large area of land that could have been otherwise used for other purposes.

Wind Power Home Incentives

Sunday, May 24th, 2009

After the Arab oil embargo of the late 1970s, incentives created by the Federal government helped drive large-scale wind power homes for both commercial and residential customers. These incentives dwindled until eventually a tax credit for residential-scale wind energy was no longer offered.

A number of states, however, have incentive programs. According to the New York State Energy Research and Development Authority, a homeowner in that state could expect to get approximately $4,000 per electric meter for a wind power home turbine. That would cover about 30 to 40 percent of the project cost. Some states have also enacted net metering laws that require utilities to purchase excess power generated by a residential wind power home at retail rather than wholesale prices.

Environmental concerns, more than cost savings, largely drive many new residential turbine installations. Even with state incentives, it can take 20 years to pay back the installation cost.

This could all change with the current administration’s economic stimulus package and budget allocations. On February 17, 2009 President Obama signed the American Recovery and Re-investment Act of 2009 into law. With a significant emphasis on wind power home technology deployment and job expansion, the bill improved upon the 2008 tax credit, by removing “cost caps.” This change allows consumers and small businesses to take a 30% tax credit off the installed cost of a wind turbine. To a consumer or business purchasing a single 2.4KW residential wind power home turbine, it will double their credit. Additionally, businesses will also have the option of receiving their credit in the form of a cash grant.
