U.S. freezes solar projects citing need for assessments. "Faced with a surge in the number of proposed solar power plants, the federal government has placed a moratorium on new solar projects on public land until it studies their environmental impact, which is expected to take about two years." (Ooops. There goes SDGEs Sunrise Powerlink Superhighway justification. There are still those coal fired plants in Mexico, though.) U.S. Dept of Energy to invest $90 million in advanced geothermal research. "The US Department of Energy (DOE) is trying to do something about that with a $90 million "Funding Opportunity Announcement"; it plans to award 26 grants to both industry and academia. "A minimum of 20% private sector cost share is required for R&D projects and funding for the awards is subject to Congressional appropriations." Hopefully, this new investment by the DOE, along with private sector funds, will help geothermal (not to be confused with residential ground source heat pumps) move forward into the spotlight. As we said before, geothermal energy has a huge potential and could be used alongside intermittent renewable sources such as wind and solar." (Why don't they just take a vacation in Iceland, take a few tours and ask some questions?) L.A. gas station gets hydrogen fuel pump. Yeah. But how many eletrical refueling stations are being put in? There was a spot on the news just last night about a company in North County that will convert your junker into an EV. Cost dependent on the batteries you choose. And Abran is still offering that conversion class every summer. Looks like this summer is full, but they're taking reservations for next year. If you're interested, I wouldn't wait as I expect interest is only going to grow and space is limited. Commuter Conversion Electric Car Class for Teachers 2008 THE CLASS IS FULL Next class will be Summer 2009. From 28 July 2008 to 8 August 2008 there will be the 2008 class where participants will learn how to convert a stick-shift gasoline powered car into an electric vehicle. The class will cover both theory of how electric vehicles are designed, and the actual hands-on installation of motor, batteries, controller, and all the other components necessary for a working and fully functional [freeway legal] electric vehicle. Workshop Coordinators are Jon Karanopoulos & Abrán Quevedo (Mr. Q). Tuition cost is $300 per workshop participant. Class begins on Monday, July 28 and ends on Friday, August 8 2008. Each class runs from 8:00 a.m. until 3:00 p.m. daily. Professional Growth Units (PGU) may be available at time of registration. Class at the San Diego Community College District's San Diego High School, 1405 Park Boulevard, San Diego, CA 92101. For registration and motel accommodations or questions contact [email protected] or [email protected] or phone (619) 744-3821. And hey, look what I found. LOL. For $30,000 I would have bought one.
It would be nice if we are starting to see that we should research environmental impacts of energy initiatives before implementation to ensure that in the future we won't have created environmental catastrophes where they could've been averted. However, I think it's probably a safe bet that the underlying intent of this moratorium is not for this reason. I could swallow this a bit easier if it were.
I believe geothermal is usually based around existing hot springs. We have several in the So. Cal area. And the technology has been used for years in France and Iceland. Instead of investing $90 million to reinvent the wheel, perhaps we should be pumping them for info and technology? Why does the U.S. have to assume we're the only ones that know anything, know the most, do it the best. (If this were true, Germany wouldn't be #1 in Solar PV and it looks like will remain so for at least 2 years.)
The amount of heat robbed from the core is lost in the noise. There are better things to worry about. Tom
The amount of energy extracted from ALL potential geothermal sources is so small as to be unmeasurable. We all ready take heat out of the earth by drawing water, oil, gas, etc from great depth. Also there are other geothermal sources, ground water heat pumps, ground heat pumps, lake water heat pumps etc that are also considered geothermal. Icarus
You forget that the earth GENERATES the heat through geologic activity. It is constantly making heat, and giving off heat. Hot springs, active volcanos etc all give up the earth's heat to the air. It really isn't like it is going to run out. Intuitively, look at the heat that is visible from the lava in Hawaii. If a portion of that heat we captured to make steam, how much electricity could be generated? My intuition, and Iceland is the example, is that most of the electrical needs could be met. Same with hot springs all over the N. American intermountain region. That heat is being lost to the atmosphere anyway. Icarus PS Geothermal does it with no release of Co2. Any percentage of fossil fuel you don't have to burn, puts you a leg up on addressing both the oil "crisis" AND Co2 emissions. Not only that, but if your really smart, you can use the heat a number of times before it is lost to the atmosphere. After running (clean) steam turbines it can be piped for domestic hot water and space heat. It really is a win/win all the way around. (That isn't to say that I am advocating to drill every here and there for geothermal, but it makes great sense to do it where it makes sense!)
So the Earth's core might cool down in 4.999999999999999 (add as many 9s as you wish) billion years as opposed to 5 billion? Pragmatically speaking, if one were to rank the order of importance of what to worry about (for now and the future), this fear should be way, way, way, way, way, ... way down on the list.
Citation please???? Going to run out is a relative term. In the next couple of centuries I would be concerned. In the next millenium, well I'll live with that. The other planets? I confess I don't really know what is going on in the core of the other planets. Can some learned person please give me a CITED education? Icarus
You assume that technology is static. Patently not true to anyone who can see anything. We have been on a petro jag for ~200 years and now we are figuring out what to do about it. I suspect, (assuming we don't kill ourselves in the interceding years, not a safe assumption!) that there will be one or two smart people born who will begin to wean us of our addiction to "foreign" geothermal energy. All damn OGTEEC! Icarus Org. Of Geo Therm. Exporting Countries, the NEXT AXIS OF EVIL! Remember, you heard it here first. We are set to invade Iceland, and then Hawaii,,,,Oh wait a minute we already own Hawaii. Damn those pesky brown Hawiians!
I have to agree with those saying using geothermal is a blip that will never register with the core temp of the earth. That said....I'm tired of hearing every suggestion shot down with it won't replace the oil we're using. That's right. It won't. And neither will....the oil we're using since we're running out of that and sooner than we think. That said....there is no ONE solution to replacing oil...but there are half a dozen or more. We have to approach the problem from many different directions with many different solutions. Depending on where you are in the country, it may be solar PV, wind, geothermal, tides, methane from landfills and animal poo, who knows? But to just sit around doing nothing hoping for some miracle isn't going to do it either. We can't just continue business as usual and just hope 1. and infinite supply of oil will magically be found 2. there will be no consequences for the continued use of and expansion of use of oil 3. we won't have to make any changes at all in the way we live. That isn't going to happen. So we can start now and make the change as painless as possible. Or we can wait and make it as painful as possible. I personally think the U.S. is STUPID to delay solar for two years. And where is our EV superhighway infrastructure?
