This paper examines wind power as a viable alternative to petroleum-based energy sources, drawing on the observations of Renner and Renner (1987) about cyclical oil crises to frame the urgency of developing renewable energy. The paper reviews global wind energy production statistics, highlights key advantages of wind turbines β including zero greenhouse gas emissions, low land disruption, and cost competitiveness β and identifies significant obstacles to wider adoption. These obstacles include aesthetic objections from environmentalists, hazards to bird populations, urban sprawl limiting available land, and diminishing federal and private funding for renewable energy research. The paper concludes that wind power, supported by coordinated national funding, can meaningfully reduce dependence on petroleum and help meet growing electricity demand.
In 1987, Renner and Renner wrote: "One year after the dramatic collapse of world oil prices, any initial enthusiasm about it has yielded to a more sober assessment of the international energy market. The predicted benefits of the oil price drop have turned out to be grossly overstated: cheap, abundant oil is clearly not the solution to the world economy's deep structural problems. Moreover, oil does not seem likely to remain cheap and abundant. Last year's turmoil is part of a larger boom-bust cycle that will almost certainly usher in a new energy crisis sometime in the 1990s."
Now in 2005, the price of gasoline seems to rise every day. Just as Renner and Renner observed in the 1980s, we are reminded β every time we fill our gas tanks β that over-reliance on oil for energy is a poor energy plan. While many options exist to create energy from non-petroleum sources, one showing increased success is the use of wind power.
Wind generates electricity when its force on windmills creates an electrical current. While the United States is using some wind energy, wind turbines worldwide generated over 14,000 megawatts in 1999. Its use is expanding faster than any other alternative energy source. India produced 1,167 megawatts in 1999 from its wind farms. Denmark, the country that pioneered the use of modern windmills to generate electricity, used the source to produce 14% of its total energy needs in 1999 (Pasqualetti, 2000).
Wind energy is what is called a "renewable" energy source β though that description is not entirely precise. There is no need to replace the wind; its renewal is generated by the Earth's atmosphere. Wind installations can be small or large and custom-tailored for the area they will serve.
The use of windmills to generate electricity has distinct advantages. Its production does not contribute to global warming in any way. It does not require building dams or flooding land to create the force needed. It produces neither contamination nor by-product wastes that must be disposed of. Wind turbines are easy to erect, easy to remove, and work well in areas where the traditional electrical grid is not easily accessed. As of 2000, the cost of electricity generated by wind was roughly equivalent to the cost of electricity generated by more traditional methods (Pasqualetti, 2000).
These characteristics make wind energy one of the most environmentally benign forms of electricity generation available. Unlike fossil fuels, wind power produces no greenhouse gas emissions during operation, making it particularly valuable in the effort to reduce carbon dioxide output and address climate change.
