Energy Prices

I want to write about something Al Gore said yesterday about energy prices, at the Netroots Nation conference.
Oil is limited. There is only so much, and the amount you can get it out of the ground and refine on any day is limited. That means that the more you depend on it and use it the more the more the price goes up. It just has to go up and eventually run out.
Solar power, on the other hand, is a new technology, so it is expensive today. But the more demand there is, the more factories are built. That means that the more we depend on it and use it, the more the price goes down.
Let me add that once you install solar your ongoing cost is very low. With solar you stop sending those checks to the energy companies.
