Anticipating life without oil is admittedly somewhat difficult. Some are predicting apocalyptic scenarios where entire societies will crumble and wars for oil resources will grow more frequent. Yet others are more hopeful, including former Fed Chairman Alan Greenspan who predicts plug-in hybrids running off of electricity derived from the production of nuclear energy.

As President George W. Bush communicated during his April 29, 2008 press conference, we are in a transition period: that is, the end of the age of oil is giving way to the beginning of the renewable energy age. But exactly what types of renewable energy are currently on the table, and what should we expect in the years to come?

Among the best sources of alternative energy today are solar and tidal stream. These are clean renewables that don't emit greenhouse gases. Biofuels are not favored due to their propensity to drive up the cost of food worldwide and cause an equal (if not greater) amount of greenhouse gas emissions; thus they are strictly a short-term solution. Hydrogen is gaining popularity, but due to issues of technology, pricing, and infrastructure, it hasn't been commercialized yet. However, another viable energy source has blown into town, and it may very well take the top spot in today's search for clean renewable energy.

According to the U.S. Department of Energy's Energy Efficiency and Renewable Energy (EERE) program, the Wind Powering America (WPA) initiative was launched in 2000 as "a commitment to dramatically increase the use of wind energy in the United States. This initiative will establish new sources of income for American farmers, Native Americans, and other rural landowners, and meet the growing demand for clean sources of electricity."(1) The initiative's four main goals include regional economic development, local environmental protection, increase in energy production and national security, and using wind power as an essential element of America's energy mix.

Since its inception, WPA has seen wind energy capacity increase fivefold from 2,500 megawatts (MW) to greater than 16,000 MW by 2007. 17 states now have more than 100 MW installed. In fact, the Horse Hollow Wind Energy Center just outside the West Texas town of Abilene is the world's largest wind farm and boasts a whopping 735.5 MW capacity. This enormous enterprise covers approximately 47,000 acres and is comprised of 130 Siemens 2.3 MW and 291 General Electric 1.5 MW wind turbines.
