Solar thermal energy is a technology for harnessing solar energy for thermal energy and it is different from photovoltaics, which convert solar energy directly into electricity. There are many applications of solar thermal energy such as drying, heating and water distillation.

The first decade of the 21st century marks a sea change in consciousness of Green marketed products. While many great strides have been made since the 60's in technology to improve water, earth, and air quality, Green has become a signature for the marketing of eco-friendly products. While European automakers have focused upon high efficiency diesel engines, American's have been taken by the introduction of Hybrid-Electric vehicles. Hybrid-Electrics were promoted vigorously by Amory Lovins of the Rocky Mountain Institute in Snowmass Colorado, a Green research organization.

Electric cars are usually driven by rechargeable battery packs but it is also possible that the electricity needed to run the vehicle is stored in an ultra capacitor or in a flywheel. In fact, the history of the electric car can be traced back to the 1830s. It was a Scottish businessman named Robert Anderson who invented the first crude electric carriage any time between 1832 and 1839. The first small-scale electric car was designed by the Dutch Professor Sibrandus Stratingh and built by his assistant Christopher Becker in 1835. http://carstudies.com/

Jatropha is a leading source of biofuel, which is widely used in Brazil, India and Philippines. It has been tested on Continental Airlines and Air New Zealand, and it powers trains between New Delhi and Mumbai. A few of energy companies are investing in cultivating jatropha trees, which are estimated to yield two gallons of oil per season.

Erst mit der Ölkrise 1973 begann man wieder über alternative Energien nachzudenken. Der explodierende Ölpreis machte den Regierungen klar, wie groß die Abhängigkeit von den ölfördernden Ländern bereits war und dass Öl durchaus als politisches Druckmittel eingesetzt werden konnte. Es wurde nun versucht, durch entsprechende staatliche Förderprogramme die Effizienz der erneuerbaren Energien zu erhöhen. Allerdings rückte damit eine andere Energiequelle in den Blickpunkt der Aufmerksamkeit. |
