Alaska Looks To Volcanos For Geothermal Energy
Iddo Genuth writes "Alaskan state officials have recently announced their intention to begin funding the exploration and surveying of Alaska's largest volcanoes in hopes of utilizing these as a
source of geothermal energy. They say this volcano could provide enough energy to power thousands of households, and according to some estimates, Alaska's volcanoes and hot springs could supply up to 25% of the state's energy needs."
if we did tap geothermal resources nationwide to get up to supplying 25% of our electrical needs within a few decades
I'm of the opinion that the human race will eventually get close to 90% of its energy needs from geothermal sources. Wind and solar probably can't deliver the wattage. What people don't realize and what they don't want to believe, is that the world is not filled up with oil in the middle. Instead, its filled with molten rock, and beyond that, molten metals. And there is a lot of it in there. All you need to do is invest in shunting sea water a few miles into the earth and harvesting the energy as it boils out. Other than the initial investment, it wouldn't take coal or oil--both of which WILL run out.
Just callin' it like I see it.
Oh come on, someone modded this *informative*?
Calling geothermal energy a "temporary fix" is about as useful as calling solar energy a temporary fix. Really, I don't think it's too shortsighted to consider an energy source that could provide power for millions (geothermal) vs billions (solar) of years as more than "temporary". Especially considering how we will have used up the relatively scarce (geologically speaking) oil resource we are looking to replace in the scale of hundreds of years. Hell, I'd be happy to see people think 50 years in advance, imagine what we could do with nuclear power if we'd invest for results with a payoff that far away...
I was going to mod him down but there wasn't a suitable category - say like 'Missing The Facts'.
First off, like how much heat energy is actually present beneath the mantle? A. Big number.
Secondly, how long it will take for the magma / iron + whatever core to cool to a point where the magnetic field decreases enough? A. Another big number.
It scares me that people with so little perception of physical reality make comments as if they understand.
Just a point for you too re nuclear power. It may outlast us but Uranium reserves are not infinite either.
Now if we could only get Fusion happening...
All in all geothermal is a great idea - as mentioned in Iceland, and I think the Kiwis (New Zealand) harvest a bit for sparks and even the UK for hot water if I am not mistaken.
No not available everywhere but whatever helps...
