Hydroelectric vs. Slow Volcanic Power [view article]
nukehydroguy,If the heavy metals counterargument had any weight, mining would have to be outlawed too. And if you consider that geothermal energy offsets coal burning, there is a net reduction in lead, mercury, etc. emitted. Most geotherm plants cool and reuse the same water anyway. Putting byproducts back into the hole doesn't seem difficult. As a poster pointed out on another article, the brine byproduct is actually a profitable source of lithium - you know... as in lithium-ion.
Road Runner,
Geotherm is available anywhere if you dig deep enough, but the red spots are the cheapest places to produce. Although the yellow-orange spots are not economical compared to prices of other sources of energy, the prices of other sources of energy don't account for costs such as oil wars, energy dependence, nuclear waste disposal, lead and mercury pollution from coal, defense of nuclear plants from terrorism, etc. Taxpayers get to bear the costs of coal and nuclear.

Basic question that I hope can be answered in this forum –either by you, Mark Courtenay, or by another contributor: Is NGLPF to be considered a utility stock, an energy stock, an industrial stock, a growth stock, a value play? Is it speculative, staid? In order to include it in my portfolio, I would like to understand how it should be viewed as compared to RZ, ORA, Excel, or Pacific Gas & Electric, GE, etc. ReplyHydroelectric vs. Slow Volcanic Power [view article]
Once geothermal generating companies get on board with T. Boone people will hear about them. One comercial demonstrating the efficency and cleanliness of the method is all they will need to realize what a gem this is.As far as heavy metals getting into the water I never heard the people in Greenland say anything about such a tale. From what I understand the pipes are set in a coil at the bottom of the well and a hermaticly sealed system is created by partially backfilling the well bottom with mud or concrete to aid in heat transfer. The water never actually comes i contact with the earth or lava. One the wells are too shallow andd the engineers avoid such extreme hot spots due to the risk involved. Two the system is a partially hermetic double loop system so the water being sent into the well never comes in contact with the generators.
The system is basically a copy of the nuclear system without the rods.

Another stock not mentioned in the article is Brookfield Asset Management (NYSE and TSX- BAM). Brookfield is the largest publicly traded operator of hydroelectric power plants in North America (though, hydro power generation doesn't generate anything close to a majority of their revenue- the overwhelming majority comes from commercial and residential real estate through subsidiaries Brookfield Properties (BPO) and Brookfield Homes (BHS)).Disclosure: Long BAM Reply

I don't understand your map. The map appears to say that geothermal is available in over 90% of the US. Is that right? ReplyHydroelectric vs. Slow Volcanic Power [view article]
As more articles are written about geothermal electric generation potential and application, more people will begin to see what a viable source of power it is, and become less skeptical of the process. They will prove to be good for the economy, as geo is one of the most reliable and constant producers, and requires NO fuel to operate, produce NO greenhouse gasses, and will compete price-wise with coal-fired plants in the production of base-load (constant production) power .As to transporting the power: many geo resources are very close to the large and growing population centers of the southwest (check the map in the article), and plants are being built in those areas. Since they are completely non-polluting, there are not issues of toxicity to local populations. Some of these can now be built very quickly: Raser Technologies is implementing a process that will allow very rapid deployment. Their first plant (in Utah ) is scheduled to come online in 2 months - they broke ground in May of this year. Reply

go to lng as we have great amountsof this natural resource to power vehicles as well as power turbines to produce geenerous amounts of moving electrons. i.e. electricity. Replyebus

Geothermal would be great if:a) it actually worked and the water they put into the ground came OUT again. (hint... it usually doesn't)
b)Transmission losses weren't an issue. Lots of geothermal energy up in Wyoming doesn't do the power hungry southern Californians much good.

Wah wah wah nuclear power uses water and has nuclear waste. Your tears are so sweet. Reply

I like this article, but it's not a question of hydro versus geothermal. It's a question of harnassing all the sources of energy in the most cost-effective and ecologically sensitive manner. Each has a role to play and, in my view, hydro and geothermal should have a much greater emphasis than nuclear. It aamazes me that nuclear is so often given the "green" tag of approval. Has everyone forgotten about heavy water discharges and spent nuclear fuel rods??? Replysion

The author didn't mention another company for this sector, RZ. Raser In building geothermal plants now and is starting one in New mexico as well. Reply1

Geothermal is great but it is not completely waste free. In many wells the water that is used becomes contaminated with toxic heavy metals that will need to be cleaned from the water and disposed of as hazardous waste. Other than that though, it is a trouble free source of power that can produce reliably around the clock. ReplyHydroelectric vs. Slow Volcanic Power [view article]
Has there ever been a good study of the pros and cons of tidal flow power generation? Also, ever a good study of the feasibility of generation using wave motion? ReplyHydroelectric vs. Slow Volcanic Power [view article]
Geothermal is 100% the way to go straightforward and long term - I like hydro, but the negatives you accurately cite are too high to me (Disclosure: mad fisherman). I am long HTM and CPTC( for the transmission side) as well as CWST which is generating power from smaller methane generators on their waste sites. ReplyGeothermal Energy Sources 101 [view article]
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 !!! ReplyHuneycutt
10 Alternative Energy Stock Speculations for 2008: Performance Update [view article]
Hi Tom:I find EEEI to be an interesting play. They seem to have some good contracts and there appears to be a lot of demand and a lot of potential for their products. However, they also have some huge problems. It would appear they are having liquidity issues and they would greatly benefit by being able to raise more capital. However, that issue is somewhat complicated by another factor; NASDAQ is threatening to delist them since they trade below $1. Despite the fact that they could seemingly remedy the problem with a reverse stock-split, the company seems to be resistant to this idea. How big of an issue do you think the liquidity/delisting could be for EEEI?
(Theoretically, they should have already been delisted, but I haven't seen anything about the current status of that.) Reply
