The world can be powered by alternative energy, using today’s technology, in 20-40 years
If someone told you there was a way you could save 2.5 million to 3 million lives a year and simultaneously halt global warming, reduce air and water pollution and develop secure, reliable energy sources — nearly all with existing technology a…
Diesel cars may promote more global warming than gasoline cars
More auto news. A Stanford researcher has found that although diesel cars obtain 25 to 35 percent better mileage and emit less carbon dioxide than similar gasoline cars, they can emit 25 to 400 times more soot per kilometer. The warming due to soot may more than offset the cooling due to reduced carbon dioxide emissions over several decades. Laws that favor diesel cars over standard gasoline, therefore, may be doing more harm than good.
