So,why do

we need them?

Why is oil and coal and gas so important?

Power Stations

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)

BUT – wait a minute!

The use of these is increasingThe world’s population is risingWe are not finding new reserves as quickly as we used to

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?

So what is the alternative?

What we need is a

Fuel-not-run-out-inator

Why else are “fossil fuels” a problem?

So what is the alternative?
