Thanks Gomor and JP. Made my day today. Don't mean to be "Scornful" just looking for a laugh. But, you know, I have learned from (lurking?) this board. I'll try not to be too much of a pest...
Check out this story (if the link works). Warmer weather leads to less coal use which leads to less greenhouse emissions. See? Global warming is self healing!
<< Gomar, do you even know what geothermal is? I don't think so, because geothermal generates no power, it consumes power, it is just more efficient than regular heat pumps >>
From the peanut gallery, this observation: With stunning clarity, iloveembrow demonstrates that the combination of ignorance and arrogance is absolutely toxic to one's credibility.
Interesting that iloveembrow mentions hail later in his post, though, considering that Hawaii just had a unprecedented hailstorm itself, leading one to believe that perhaps it WAS all those pesky maids.
It appears you were up all night googling on geothermal.Hence, I will answer you. Have you added transmission and distribution costs to the 3 cents it takes to get electricity to the customer. Those "costs" can be up to 30% of the "cost" consumers pay. How about the amortization of the capitol cost and financing as well as the operation and maintenance cost? Did you add those "costs" on?
This is the last you will hear from me on geothermal power. Geothermal power represents leas than 1/2 of 1% of the power generated in the United States.Geothermal power as a percent of the overall power produced will become less and less as the national electrical power generation is expanded. At best the geothermal power plants are small.Do they even average 30MW in size?
If one is going to champion building more of these small geothermal plants,then you must consider where can you build them.If you argue for more of these small geothermal plants,then you open your self up to competing with small prepackaged nuclear reactors.Small nukes can be build where there is no geothermal power.
It is not worth my effort to continue a discussion on geothermal.
There was an earlier discussion as to what was the cost of geothermal electric power TO THE CUSTOMER?
I had heard 3 cents per kilowatt hour, but Bill Tarasen thought that was the cost of the power at the generation station, not the cost to the domestic customer. I just found this literature source that indicates that perhaps the 3 cent rate is actually the rate to the domestic customer:
<<The cost to produce electricity in this manner remains quite low, as of 2011. Power generated by the geyser-based plants in California only costs customers slightly more than three cents per kilowatt-hour, according to the Department of Energy. The U.S. national average is about 9.5 cents.>>
Perhaps with some more research we can clear up what the costs really are.

Hi Bill Tarasen,
Possibly you aren't current on Chevron's plans to use solar energy:

I've been looking for some more statements on the cost of geothermal power. I think that it depends a great deal on the nature of the hot formation. The second page of these each has an estimate of cost:
The next source has the lowest cost estimate
<In 2009, investment bank Credit Suisse calculated that geothermal power costs 3.6 cents per kilowatt-hour, versus 5.5 cents per kilowatt-hour for coal.">

Golly Green, you mean to tell me that what I have been saying all along is true? Don't tell Stevo. Low effeiciency, broken circuits, I can't wait until the cheap Chinese stuff gets verified.
When a large oil company builds the largest photovoltaic plant 30 years ago and drops it like a hot potato after all that expense, there had to have been a reason. Sorry, I only talked to their engineering, not the spin meisters.
It turns out Hawaii has two refineries.That makes you half right which is a big improvement for you.
You are a true innovator as you continue your quest to replace coal fired and natural gas plants with wind and solar.Do you have a target date as to when the last coal fired plant and the last oil and natural gas plants will be history in Hawaii?
What is your projection of the electric rates to the Hawaiian customers when you are successful in shutting down their oil and gas plants? More than 40 cents?
Turns out that Hawaii has one 100 MW coal fired power plant (using sub-bit coal from Indonesia), one oil refinery using mostly Alaska crude, and a syngas plant that uses products from the refinery. The refinery has to produce a lot of jet fuel for the airline industry.
But apparently the pineapple and sugar industry have declined significantly, seeking cheaper labor elsewhere. This has significantly reduced the amount of raw materials available for biofuel development. Kauai used to burn a lot of bagasse for electricity back in the 1970's, but now mostly burns petroleum for electricity. Here's the fuel mix for HECO, which covers the other islands:
So whatever renewable energy is produced there will most likely be replacing petroleum based energy. So, yes, Hawaii is a good place to start. But so is California and the entire southwest. Not to mention the wind power on the great plains, or the cow poop here in Wisconsin, or...
