Solar Energy
Chevron seems to be taking the lead in facing up to reality, at least among the major oil companies. Dave Johnston just showed me this website which takes head-on the issue of peak oil. They're trying to bring the cumbersome bulk of public awareness around to the realization that oil is not a renewable resource. They've set up a forum for discussion which, at my cursory glance, seems to be pretty good. I am now going to rant. It's just a little rant, over nothing of particular importance, but it seems pretty fundamental to me. All energy consumed on this planet is solar. There is one exception, which I will acknowledge in a bit. They speak as if wind energy is one thing, while oil is another. Every single type of these energies came at some point from the sun. Wind is created by the sun heating up one area of the atmosphere, which rises, and more air rushes in to replace it. Oil is ancient bio-mass, which at one point was either vegetable in nature, or gained it's energy from veggies somehow. You get the idea. The exception is nuclear power, either fission, or potentially fusion. Until we get fusion up and running (another few centuries), we'll need to rely mainly on the sun. Quite a bountiful source. But we need to find a slightly more efficient manner of using it's energy than oil. Converting solar energy directly into electricity seems ideal, if we could only resign ourselves to investing money in it. We could convert that directly into hydrogen through electrolysis for cars. I'm on a tangent. I'm sure I've talked about this before. Sorry. I'll shut up now. I'll also try to write something on a more regular basis. Does anybody read this?

There's also geothermal energy, which is energy from the earth's formation captured in it's core.
And some ecosystems live entirely off of elements like methane, though whether that's organic in origin or not i'm not sure.
Geo-thermal is a viable short-term solution, althought expensive. In the end, though, it's not adding available energy to the Earth, just moving it around a bit. I wonder if anybody's looked into the long-term consequences of taking heat from the core of the Earth.
Methane, young man, is organic (can't you see the little C's and H's floating by in the innards of your brain?) but it is certainly not an element! I'm scandalized! It is in fact CH4, with the hydrogen arranged around the carbon molecule. I don't why I just brought that up. The point is, it takes energy to create that molecule, and then that energy is released when it reacts with oxygen, or is metabolized. It doesn't have anything to do with mass energy additions to our "economy".
