Have we reached peak oil and can we survive it?

Some experts in the oil industry believe world oil production peaked in 2005 or 2007, even the most optimistic predictions go to only 2020. I have really been thinking about peak oil and sustainability lately, and I think the US is in for some VERY hard times in 5 to 10 years. I see NO efforts for oil conservation and it might be too little too late by the time people even begin to use alternatives in any significant way.

My hope for the future comes from nanosolar and nuclear energy but we still need an oil based economy to make that transition, it would take at least a minimal of 20 to 40 years to make a transition on that scale and we only have 5 to 10 years from peak oil AT MOST. Our whole economy is based on unending growth and that is unrealistic with the finite resources we have, this includes water, coal, and other non-renewables too. At worst, our entire civilization could collapse and this has happen before to the Romans and the Mayans.

We might have to go to a more localized lifestyle in the future and that's if we make a peaceful transition. I have been trying to factor peak oil into my career choice and future expectations. Maybe emerging technologies can get us out of this mess like nanotechnology, solar, nuclear, bio, geothermal, wind, and natural gas.

What do you think will be the implications of diminishing energy resources on gobalization, US economy, and your personal future?
