Global Warming and our Changing World

I read a couple places that we're close to a peak in oil production that will cause permanent blackouts worldwide.

I had hoped that alternative energy technologies could get around this, but some people say you need non-renewable energy sources in order to create renewable energy sources.

Oil energy can make solar panels. Then, can't they take the sun's energy, and use it to make more panels? I hope so, but it seems possible that we'd need a lot of energy to create enough alternatives to sustain current consumption levels. At the rate we're going, it doesn't look like we'll have enough alternatives on hand once Big Oil dies out.

At that point, there'd probably be a huge dip in how much energy we had. We could work on new energy sources, but what if we get caught up just trying to move food and water around?
