Fossil Fuels?

Question

How long will the fossil fuels: Coal, Oil and Natural Gas last?? Sources would be good too. Thankyou. xx

Answer 1

Just long enough to allow us to totally screw up the climate. No one knows for sure, they keep locating new deposits and extending the date. But the oil is estimated to run out in fifty years . There's a lot more coal, and we don't use as much, so you'd probably be looking at well over one hundred.

Answer 2

I went to the effort to figure it out once based on data from the US dept of Energy. I felt like between 2025 to 2050 the price of oil would become too much too bear for average consumtion. but global warming is making arctic ocean oil easier and cheaper to get so the estimate will continually change.

this is a nice comprehesive projection
