I'm pretty sure the Oil supply has somewhere around 100 years left???
The thing is, we are all worried about what we're going to do but until the bloody US, China and India stop there hurrendous consumption rates then not much is going to change.
Look on the bright side, if you had said to someone 100 years ago that in the next century man (and woman!) would develop a means of jet propelled flight around the world in contraptions that operated 5 miles above the earth at over 500mph they would have sent you off to the looney bin!
With this in mind im pretty confident that something will be invented to overcome the oil crisis.
