solar advances --> what advances? there are still several, legitatmate hurdles to be made before solar is even viable. and it still doesn't replace the pesticides, fertilizers and un-usable as a transport fuel. logistics of solar power is mind boggling.
You continue to understate what technology is available today. Top end solar cells are nearing 40% effeciency. More economical ones are 15-20%. To say solar cant be used for transport is would be false. Solar would be a natural enhancement to hybrid cars since they also have an electric subsystem. Any given car would have room for a couple square meets of solar panels. Trains are also diesel electric. A train 100 cars long would be able to have an entire acre of solar panels across the top of its cars. This would reduce the amount of diesel consumed for transport. A semi would have almost 450 square feet of solar panels that it could have.
In the next 10-15 years i would not be surprised if solar become cheap enough for the masses.
wind advances --> see above. also probably our best alternative
coal advances --> we also have a finite stock of coal and all indications that are that it isn't 250 years like everyone touts it to be. it's more around 100 (which is great imo, fusion should kick in by then). however, it is a heavy polluter, and i hope to god the green lobby doesn't stop it. it also doesn't replace pesticides and fertilizers, however, i can see research being done into it to replace oil.
it can already replace oil. Germany made gas of coal 50 years ago. It can already be made clean. We can and will find new ways to make pestidicde and fertilizers.
oil advances --> cheap oil is running out
re-using and recycling plastics and other materials will never alleviate our dependance.
Changing world technology claims to have an effecient technology for recycling these products. This recycling can also be done cheaply. Hopefully their technology is real.
check it out
there is only so many times you can reuse the oil before it becomes unprofitable to do so. also remember that such processing consume oil as well and thermodynamics state you can never get back what you put in. so we will always be on a downwards slope with recycling/reuse.
The amount of energy required to recycle a recycled plastic bottle, is the same as the cost to recycle a new plastic bottle. Assuming they are like products.
deep sea oil is not very viable. in the gulf of mexico alone, there have been many wells drilled, but only a couple of them have hit oil. it is also extremely expensive and the quality of oil is not as good. and the whole point of peak oil is that we are going to lose cheap fuel as a resource base.

wells being replenished is more likely due to a deeper source of oil than oil being generated. the processes by which oil is formed take hundreds of millions of years.
You are missing the point of peak oil. I think everyone realizes that oil is a finite resource and that is become more expensive to extract. However there are many more ways to generate the things we need without oil, oil currently just happens to be cheapest right now. Overtime that will change.
and regardless of all the innovation and technology, there _HAS TO BE_ a time when growth can not be sustained. this is the core of the peak-oil debate. growth on a finite world can not be sustained indefinately. bacteria in a petri dish could cover the earth 3 meters deep in 48 hours if their growth is unchecked. fortunately for us, they never get that far, some sort of limiting agent hits upon them. we are not immune to the same laws that bind bacteria. it is simply that the earth is our petri dish and we have covered it. the question is, can we sustain our coverage or will there be a crash.
The population of the earth is starting to stabilize and according to latest predictions it will start to contract in 30-50 years. This will no doubt cause a contraction in global demands for resources. We appear to be limiting our own growth.
