Actual experiance in 'geothermal heating & cooling' in a co-op residential community in Lafayette Park, Detroit has proved successful after initial installation glitches in 2002. For a 1,200 sq ft 2 story townhouse the monthly cost of H&C including lighting and appliances is currently reported to be an amazing $29.00 !!! ReplyGeothermal Energy Sources 101 [view article]
U.S. geothermal industry experiencing "dramatic growth surge" with expectations that total power production (currently 3 million homes) could triple over the next few years.GEA together with Ormat (NYSE:ORA) and Glitnir Bank will host a workshop on july 23 in NYC to introduce geothermal energy to the NYC financial community.
Among the present: Google.
Google announced that geothermal energy will be one of their focus areas for new investment.

A great job of quickly covering the basics of a very promising technology. The big Island of Hawaii has a 30 MW geothermal generating facility.The biggest problem with geothermal is that it could really replace coal as a source of baseload power so it is seen as a threat to the very powerful coal states. The DOE budget was reduced to zero last year and even a bill to authorize $95 million for development was ignored by the DOE as they budgeted only $30 million for the 2009 budget. Powerful political forces don't want the fantastic potential of geothermal to be realized. The heavily subsidized fossil fuels get all the money ($400 million for coal in 2009). Even Barack and Hillary are trying to outdo each other to get coal votes with endorsment of "clean coal" Geothermal is the answer if we can just cut through the political manuvering financed by $13 billion in subsidies. We need a Manhattin Project in geothermal. Reply

drilling 10km underground is not an easy feat.But geothermal is a renewable energy. inexhaustible? many will debate on this.
As long as there is magma underground. that is a heat source. Reply

Alcoa has a geothermal plant in Iceland. Worth taking the tour. Not much to see on the geothermal part but the making of aluminum is a little bit intersting. ReplyGeothermal Energy Sources 101 [view article]
One cannot cover an entire field in one article, but its a good summation.The article is about the past, present and future of geothermal.
As for the past: while there have been temporary setbacks, everytime someone derided the sector they have been proved wrong. Also in the past: fossil fuels were cheap & plenty, environmental issues ignored, but those days are gone!
Presently some 3 GW in operation and an additional 3 GW in geothermal devellopment worldwide.
Best and safest stock, at present: Ormat technologies (ORA). Vertically integrated (from drilling, well completion, modular powerplants, maintenance to electricity sales) Rankine engine technology gives (ORA) niche advantages in low to medium temp. wells and clean tech sector. This year to surpass 1 GW powerplants sold, with millions of hrs of operation. Recently 2008 Q1 earnings above analysts estimates. Sector seems to be heating up somewhat, the sale of 3 million+ shares to Lehman is a good sign as it indicates they expect growth, wich is not surprising with fossil fuel prices and carbon & pollution legislation becoming a liability (risk) to utilities.
As always investors should try to be a little ahead of the future. And the future looks bright. Alcoa (aluminum is energy intensive)sees great future in supercritical high temp. geothermal, is drilling first well in 2008, 2 new 4 km wells to be drilled in 2009 and 2010.
Plant expected in operation 2015.
There is also an increasing probability that the drilling and well completion cost/depth function will become linear -as opposed to exponential in conventional technologies used in the oil, gas sectors.

I propose a toast to the Harry Potters of drilling.

I'm fascinated that Hawaii doesn't consider this possibility .. Lets face it, they have volcanoes and plenty of water... In fact the Big Island is ripping their hair out discussing a 'garbage incinerator' to produce electricity from their waste. At present, the electrical needs are furnished by importing fossil fuels.... Seems a no-brainer to me. Combine the waste burner and geothermal and discontinue the fossil fuels.Thx jegan Reply

I enjoyed the article and I wanted to print it, but was unable to effectively do so. I don't know if the problem was on my end or the other. ReplyGeothermal Energy Sources 101 [view article]

Besides geothermal sources, tidal flow turbines could provide enormous amounts of electricity. The age of combustion will come to an end when all alternative energy sources are exploited: solar, wind, tidal flow and geothermal. ReplyGeothermal Energy Sources 101 [view article]
good overview but the author obviously doesn't understand many of the technical and financial issues involved...for instance, deposition of norm (naturally occurring radioactive minerals) and other scale on incoming and outgoing streams in well casings,.... frac'ing 30,000'+ wells ?, ...let alone the cost of drilling and completing wells to those depths at over 100 MM$ each!....now if every city was built on a shallow geothermal deposit you might be able have some impact...but they're not!

Why are there no efforts under way to build geothermal power facilities around the periphery of Yellowstone? Previous calderas there extend beyond that boundaries of the park, so there is the possibility of drilling outside the park and establishing geothermal energy plants outside of Yellowstone, and given the minimally intrusive nature of geothermal plants (no smokestacks or fuel residues to pollute the environment, relatively modest facility requirements), it would seem to be in the nation's interest to sacrifice a small valley or two inside the park for the extraction fo geothermal power.Considering that amount of coal-fired electricity that this could replace, it would seem to be, on balance for the nation, a very good environmental trade-off.
The amount of energy available in the Yellowstone caldera is sufficient to power the entire nation for a long time. Yellowstone is a VERY large area, and including a geothermal power plant or two within it would not destroy the natural beauty of the other 99%. The biggest objection seems to be that extracting significant amount of geothermal energy would shut down Old Faithful, based on the experiences with much, MUCH smaller geothermal resources in Iceland and New Zealand, where geothermal energy extraction has had an impact on geysers as far away as 10 km from the point of extraction. The Yellowstone caldera is approximately 40 km in diameter, a MUCH larger source of geothermal energy, and has more than 75% of the world's geysers. I think we could manage to not disturb Old Faithful. Reply

good article provides a good starting point for research ReplyGeothermal Energy Sources 101 [view article]
this article needs more research; as CPN headquarters are in san Jose and Houston, not San Dieo! Reply
