1. New ways to conserve energy Rachel Lindgren Computer Applications

2.  Electric cars emit 10 times less nitrous oxide (NOx) than gasoline internal combustion engines.  They also have Improved long term energy storage and nano batteries  100x faster battery recharging  By soaking the matter found in conventional lithium ion batteries in a special solution, lithium ion batteries can be recharged 100x faster. The research was conducted by Gerbrand ceder of the MIT. The researchers believe the solution may appear on the market in 2011

3.  Natural gas has the highest energy/carbon ratio of any fossil fuel, and thus produces less carbon dioxide per unit of energy.  The major difficulty in the use of natural gas is transportation. Natural gas pipelines are economical, but are impractical across oceans

4.  The term most commonly refers to hybrid electric vehicles (HEVs), which combine an internal combustion engine and one or more electric motors.
