Burning fuel releases carbon dioxide emissions which adds to global warming, therefore less fuel used means less released heat, so if we use 5 gallons of fuel instead of 10 we have cut our fuel emissions by 50%.
by saving fuel
not too sure on this one, but I'm going to say power conservation. Less power consumed is less fuel used to give that power energy
Global warming/ the fuel
It will cause global warming
No, hybrid cars were designed to use less fossil fuel, thus slowing global warming.
Global warming.
Recycling saves a little energy, usually fossil fuel energy, so this slows global warming a tiny bit.
* global warming * bio-fuel
Because uranium has no contribution to global warming.
because of the burning of fossils and fuel
Acid rain and global warming are the man two risks using oil as fuel.
