Wind Power

Did You Know..?
- The earliest windmills were located in Persia and featured large paddles.
- The largest windfarm, Horse Hollow Wind Energy Center, is located in Texas and provides enough energy to power 220,000 homes per year.
Wind Power Basics
Wind power is a time-tested form of energy, once used for grinding grain, irrigating crops, and sailing ships. Wind turbines have been developed to rejuvenate wind as an alternative energy source that can provide plentiful, clean, emission-less electricity. The current technology utilizes large propeller-like blades that turn a rotor for electricity generation that can be fed into a national power grid. Large farms with turbines collect wind energy on dry land as well as in shallow waters through offshore wind farms. In the US, wind energy accounts for 6% of renewable energy generation and 0.8% of total electricity supply.
The disadvantages of wind energy are the inability to single-handedly provide energy independence, negative impact toward the bat population, and unappealing aesthetics of large turbines. Research advances are aimed at improving turbine manufacturing costs and optimal blade design for efficient wind collection. Policies used to push further growth of wind energy are the Renewable Energy Production Tax Credit, the Renewables Portfolio Standard, and the Small Wind Systems Tax Credit.

[edit] Policies In Use
- Renewable Energy Production Tax Credit Extension: The Production Tax Credit (PTC) applies a 1.9-cent per kilowatt-hr credit for the first ten years of a renewable energy facility’s operation. The 110th Congress extended this policy, first introduced by the 109th Congress, via the Tax Relief and Health Care Act of 2006 (H.R. 6408) until December 31, 2008. The credit is provided specifically for renewable energy such as wind, solar, geothermal, and “closed loop” bio-energy facilities. Renewable Energy PTCs have been frequently allowed to expire before reemerging as new legislature. Individual states have also begun to increase favorable renewable energy policies. Lapses and spurts of developmental policies cause volatile variations in wind power capacity (Figure 1), demonstrating the importance of extended, consistent support for wind energy for sustainable growth. Wind energy proponents urge the 111th Congress to pass a long-term PTC extension of at least 5 years. [1]
- Renewables Portfolio Standard: The Renewables Portfolio Standard (RPS), or Renewables Energy Standard (RES), is a policy making use of competitive market mechanisms to encourage growth of renewable energy sources. Electricity supply companies are required to purchase a portion of their energy from renewable energy generators. Thus, a market is created in which renewable energy generators can compete to provide energy to suppliers. The competitive nature of this policy may allow electricity to be provided from a diverse array of American renewable energy. While the policy does not specifically favor a particular renewable energy technology, those that can lower costs the most will thrive over other technologies. This may help guide the evolution of the most cost effective renewable energy. Twenty-six states and the District of Columbia have adopted a RPS. Nationally, an RPS was recently passed in 2007 by the House of Representatives. The RPS did not pass in the Senate’s energy bill. [2] Had it been passed, a 15% RPS requirement by 2020 would have been established, as well as increased gas mileage standards and a tax increase targeted at oil companies. [3]
- Small Wind Systems Tax Credit: This policy provides a federal investment tax credit to help purchase small wind turbines for use in homes, farms, or small businesses. A small wind system of 100 kilowatt capacity or less will earn 30% of the total installed cost, though not exceeding $4000. For homes, the credit earned is the lesser of $4000 or $1000/kilowatt of capacity. [4] The Small Wind Systems Tax Credit was established as part of the Emergency Economic Stabilization Act of 2008 and is valid until 2016. [5]
- Clean Air Interstate Rule: The Clean Air Interstate rule was issued by the EPA in 2005 to provide clean air by reducing air pollution that crosses state boundaries. [6] This policy permanently caps sulfur dioxide and nitrogen oxide emissions in the eastern US. The American Wind Energy Association supports the Clean Air Interstate Rule, as wind energy is a zero emissions energy source.
[edit] Proposals for Future Research
As the Nation’s higher wind speed sites fill with growing numbers of wind turbines, lower wind speed sites become important to continue to grow capacity. The National Renewable Energy Lab (NREL) and Sandia National Laboratories are working with industrial partners to create efficient low wind speed technologies for use in unused low wind speed sites. A wider availability of such cost-effective low-speed turbines would further establish wind energy’s position in the Renewables Portfolio Standard and further encourage the use of the Renewable Energy Production Tax Credit.
Wind Partnerships for Advanced Component Technology (WindPact) aims to enable technologies which reduce the cost of wind energy. [7] Often, the government-industry partnership designs and tests components (such as new blade designs, drivetrains, or rotor configurations) and troubleshoots problems that arise. WindPact also supports technology transfer from the lab to the industrial setting.
NREL provides support to the International Energy Agency Wind Energy Executive Committee. Here, research has been focused on modeling studies, offshore wind technology, and integration of power sources. [8]
The Bats and Wind Energy Cooperative (BWEC) was formed in 2003 by Bat Conservation International (BCI), the US Fish and Wildlife Service, the American Wind Energy Association (AWEA), and the National Renewable Energy Laboratory of the US Department of Energy (NREL), and funded by numerous industrial partners. [9] BWEC has been primarily concerned with studying and understanding the effect of wind turbines on the recent increase in bat deaths. [10] While wind energy continues to grow, the increase in fatalities of bats, who are predators of agricultural insect pests, pollinators, and seed dispersers is a concern for conservationists.

[edit] News Stories on Wind Power
- The Federal Energy Regulatory Commision(FERC) approved a return for investments on a porject to create a “superhighway” for a Michigan company. This highway would be 300 miles and transport 12,000 megawatts of wind generated power from the midwest. 300 homes can be powered by one megawatt of the generated wind power. The highway has been nicknamed the Green Power Express and is expected to boost the midwest’s economy. Permits and planning still need to be worked on but it is expected for the project to be online by 2020.
- Although President Obama focused part of his campaign on renewable energy, there are several roadblocks to making this a reality. The Stimulus provides for $2 billion for transmission lines to transport energy but in reality roughly $100-$200 billion is needed to complete the project. It is expected that private donors will fund these projects. Additionally, turbines and transmission lines will be placed in remote areas such as deserts and small community where citizens are already beginning to oppose their construction. The transmission lines would need to be built to reach faraway cities where the most power is needed. Another problem is the that nature is unpredictable. Ideal conditions for wind or solar power will not always be present. While this is a step in the right direction, problems such as financial, environmental, and logistical ones are arising.[12]
- A recent report has stated that the cost of building a system to transport electricity created through wind power to the edges of the country would be between $50 and $80 billion. [13]
- A new weather forecast system is being developed in hopes of better predicting and tracking wind for wind power generation. This will help companies rely less on coal and natural gas since they will be able to better control wind power. [14]
