While they sound good on the surface, when you look at them more closely it is easy to see that they entail more drawbacks than benefits. First of all these biofuels are not effective energy sources because they require nearly as much energy to produce as they end-up containing (same goes for hydrogen by the way). Various studies show that ethanol...
A comprehensive new MIT-led study of the potential for geothermal energy within the United States has found that mining the huge amounts of heat that reside as stored thermal energy in the Earth’s hard rock crust could supply a substantial portion of the electricity the United States will need in the future, probably at competitive prices and with minimal environmental impact. An 18-member panel led by MIT prepared the 400-plus page study, titled “The...
