3. Are all forms of energy as useful?
(or are some more useful than others?)
• What is the least useful form of energy?
• What is the most useful form of energy?
12. When will they run out?
Based on current use, current world population
and current rate at which we have been finding
new reserves
• Coal 119 years (2128)
• Natural Gas 63 years (2072)
• Crude Oil 46 years (2055)
14. The use of these is increasing
The world’s population is rising
We are not finding new reserves as
quickly as we used to
15. When might they run out?
• Coal 119 years (2128)
37 years (2049)
• Natural Gas 63 years (2072)
26 years (2038)
• Crude Oil 46 years (2055)
21 years (2033)
How old will you be in 37 years?
16. So what is the alternative?
What we need is a
Fuel-not-run-out-inator
