I'm going with 50, and I think it will ultimately be any success in nuclear fusion that makes the final decisive difference, but I'm curious to see what you think.

I said 50 in 2005, so I'll still with saying 40 now. Cars might still not run on renewables then, but the electricity grid will likely be 95% renewable, and only relying on gas for emergency backups.

Oil has already been virtually elimated as a power source for electricity, Coal will head the same way soon.

I can agree with that. Which technologies do you think will dominate the renewable energy grid?

In the long term probably Tidal, there are some extremely ambitious projects proposed in the Bristol Channel, although theymay well be pipe dreams. I think Mostly wind, followed by tidal and solar. With more pumped storage and probably a small gas reserve for the most unstable periods.

I think it would be worth having a 5% non-renewable backup, although in the future technologies may come about which negate the need for it,
