Alternative energy


Alternative energy

Alternative energy is typically defined as coming from sources that do not deplete natural resources or harm . Wind power is a typical example. The term "alternative" is used to contrast with fossil fuels according to some sources. Renewable energy differs from Alternative energy in that it may have significant environmental impact, as is the case for most hydroelectric dams.

Alternative Energy Adoption

Due to a steadily rising gas price in 2008 with the US national average price per gallon of regular unleaded gas above $4.00 [ [http://money.cnn.com/2008/07/02/news/economy/gas/?postversion=2008070206 Gas Prices post third straight record, CNN Money] .] , there has been a steady movement towards developing higher fuel efficiency and more alternative energy vehicles for consumers. In response, many smaller companies have rapidly increased research and development into radically different ways of powering consumer vehicles. While Hybrid Vehicles (such as Toyota's Prius) and Electric Vehicles (such as the Tesla Roadster) are commercially available, other technologies such as fuel cells, flywheels, and ultracapacitors are starting to emerge as viable options.
