so basically when oil goes the world economy is going to crash?
biger problem is geting the fuel to run the machines. fuel for forklifts and sideloaders then fuel for shipment...
Depends how pessemistic you are

I mean in the modern day almost everything uses the stuff - Transport networks, packaging, powerplants (most). So once the oil runs out of effective use before we can outfit basically everything with renewable soures of energy, I would expect it to crash.
However, when I say everything I refer mostly to power, transportation and argiculture ^^ But it's all opinion to how long oil has an effective lifespan for

I'd give it 10 years, 15 max
Maybe once fuel gets too insanely expensive, like up to $5-6 a gallon, we might consider solar energy?
Sure, it costs a lot less, and it isn't as efficient, but it's much better for the environment!
Woo!

I get to go all nerdy on everyone!
The problem will solar is sheer expense, without much power being produced - especially ground solar stations, in england with only 1MW per square metre of light falling on the ground in sunlight , it's hardly ecconomic spending millions of pounds installing solar stations - especially since alot of England is either protected countryside, cityscape or agriculture. Or, more importantly never sees sun
Places like africa or deserts recieve 3(sorry can't cite the article, but it was in NS or a NASA article) MW per square metre. Now, that would be viable as africa is a big place

However, it wouldn't benefit any country who desperately needs to find alternatives to oil (eg, China, America, England).
However, there is a way for it to work

What alot of countries are hoping to do is to put solar cells into orbit around the earth, where the amount of light is 100MWpSM(I think! I heard that today, so if I'm wrong please don't shoot me xD) Anyway, this will be collected through an array of solar cells which then beam the energy produced back to earth through microwaves. These microwaves can then be used for energy - I imagine they could either boil water into steam and force that through turbines, or use the photo-electric effect to cause a current flow
So yeah...There's an explanation of solar

It's a viable source I think so long as everything was electric and there were charging stations about ^^ However we've still got the problem of planes...Which need kerosine to produce the thrust they require to get off the ground, so fishkeeping is still vulnerable
