What’s a sensible US strategy for climate change and peak oil?

climate changeIt does not have to be mysterious anymore what the US, and by implication, the world can do about climate change and peak oil. It is to deploy the appropriate amount of wind, solar, and electric transportation. With this strategy, we have the knobs for all the results we want: less and less carbon dioxide, and reduced need for oil. What more do we want?

Naturally, we must answer two key questions:

  1. How much would it cost?
  2. How do we deal with wind and solar intermittency?

It used to be that wind cost too much and solar cost way too much. Those days are gone. Now wind costs about the same as new coal plants (which is to say, as little as anything to make electricity), and solar costs (depending on local sunlight) only about half again more. (Of course, in less sunny places, solar prices go up significantly. This is why you hear so many different economic numbers quoted for solar. Small systems are also significantly more expensive than large ones, although most of this is the cost of middle-men and not hardware.) (more…)

Getting Real on Wind and Solar

Getting Real on Wind and SolarPerhaps no recent article irritated me more and made me feel more vulnerable as a solar professional than James Schlesinger and Robert Hirsch’s Washington Post op-ed, “Getting Real on Wind and Solar” (April 24, 2009). The op-ed said we shouldn’t take solar and wind seriously, because they are unpredictable and cannot be turned on at will. There is a grain of truth to their statement. It is a serious criticism of wind and solar, and probably the most telling after the worst one – high cost. But I think it is because high cost is being overcome, especially in wind, that this next level of criticism is being raised. That’s progress.

I authored a response with Bundestag member Hans-Josef Fell, the co-author of the German feed-in tariff legislation (see Fell’s presentation at our kick-off symposium here). The Washington Post didn’t see fit to print it. Maybe they had not heard of the German feed-in tariff or its transformational importance to the global PV market. (more…)

Solar Power: The Teddy Bear of Energy Sources

Is there a more encouraged sympathy energy source than solar energy?

Its fuel material is striken from the sun, which is comprehensible and accessible almost anywhere. It’s overwhelmingly pure to run. It’s easy to construct and sustain. The large support systems can utilize it to manufacture green grid power, but you can also place it on your own roof to become your own support system or to make it off-grid.

And did I point out that it’s maintained by THE SUN?

(Full disclosure: I do some work for a solar power company in Virginia knowns as Secure Futures).

It’s no surprise that public encourages solar power, with 92% of Americans in a 2009 poll claiming that it’s significant to work out solar energy sources. Particularly, environmentalists including My Canadian Pharmacy admire solar energy best of all amoung different energy resources. It’s as pure as wind power, but solar is much less questionable.
