Even renewable energy should be used and produced efficiently

There's an old saying in biology that poison is dose-dependent, recognizing that everything is poisonous at the right dosage. Drinking a glass of crude oil will make you sick ... but so will drinking 50 gallons of water. Atmospheric CO2 concentrations of 600 ppm would radically change life as we know it on the earth ... but so would atmospheric oxygen concentrations of 500,000 ppm O2.

This isn't meant to suggest that all poisons are equal, but simply to recognize that there is nothing so good that it won't kill you at a high enough concentration. And what is true for chemicals we may ingest is no less true for public policies we may embrace. From police budgets to formal education, what's good in moderation is problematic in abundance.

And yet when it comes to energy and environmental policy, we continue to presume that our generation is smart enough to know the silver bullets, even while we lambaste our predecessors for failing to comprehend the full scope of the silver bullets of their day.

Another rate increase in the name of cheap coal

Duke Energy just got approval to raise rates 18 percent to cover the continued rising price tag for its 630-MW planned coal plant in southwestern Indiana.

The new price tag? $2.35 billion, or $3,730/kW.

By my highly unscientific but quixotically regular analysis, that's a new record, just topping AEP's $3,700/kW proposed facility in Virginia. Way to go, Duke!

One note: This plant will not sequester its CO2, and $2.35 billion does not represent the full cost being borne by Indiana ratepayers:

On Wednesday, the commission also approved Duke Energy's $17 million plan to study the plant's potential to capture a portion of its carbon dioxide emissions as part of the company's proposal to possibly store the gas permanently deep underground.

So not only is it expensive, but it's also environmentally dangerous. But if we throw a few million ratepayer dollars at "studying" CO2 sequestration, maybe we can put a nice report together showing that someday in the future, it will only be expensive.

This apparently was insufficient to appease the environmental community:

Environmental and government watchdog groups oppose the plant and have sued to try to halt it, calling the project a huge waste of money that would be better spent on renewable energy such as wind farms. They also warn that its price tag could go even higher if Congress acts to impose caps on carbon dioxide emissions linked to global warming.

Crazy hippies. When will they learn? We need to burn more coal and raise power prices because coal is cheap. Why is that so hard to understand?

End of year musings on coal and its competitors

Some thoughts as we get closer to a new energy policy. Our total U.S. electric grid has a peak capacity of just over 1,000 GW. (That’s 1 billion kilowatts or, […]

The VC models are to blame, not the green technologies

It’s worth reviewing this great presentation from the folks at @Ventures: [vodpod id=Video.16097730&w=425&h=350&fv=] If they’re right — as I believe they are — we are soon going to see lots […]
