Although they seem to be growing in popularity, hybrid cars haven’t taken over the vehicle market just yet. However, it is more than likely that this won’t be the case for long. Hybrids as a whole have been around for a while, one of the first true hybrid vehicles as a Lexus Hybrid released in 2004. 8 years on, and …

Nuclear energy has been around for a long time. All the back to Einstein’s formula E = mc^2, the potential in harnessing the energy by a small change in mass has been known. Apart from being the foundation of nuclear bombs, as well as massive environmental disasters such as Chernobyl and the Fukushima Daiichi in Japan last year, nuclear power …

U.S. ENERGY POLICY IS “ALL WET” WHEN IT COMES TO HIDDEN COSTS 100,000 Gallons of Water to Produce a Single Megawatt Hour of Electricity?
