The oil isn't going to run out soon, there's still huge reserves of it, it's just in places that are hard to reach and with that comes higher costs to reach it and higher costs to the customer. In this program they do the sums on renewables, nuclear etc. and it's just not possible to make the number of wind turbines, nuclear reactors, bio-fuel farms etc. etc. we need. Fusion power is the only solution.
We're going to get to a point soon where we're going to have to seriously fund fusion power, it's the only solution, it's stupidly underfunded, which is why it's always 50 years off. Last year we spent more money on phone ringtones than on nuclear research.
