Yesterday’s guest blogger wrote: The idea of collecting solar energy from the upper surfaces of already constructed buildings seems like the least intrusive and most efficient method to utilized light, in my opinion. It doesn’t shade the natural ecosystem and …
My friend Geoffrey Nicholson comments my post “Renewable Energy and Basic Physics”: Craig, I couldn’t agree more. Other than geothermal energy, all the other sources of energy available to us originally came from solar energy and with a rather lossy …

My old friend Peter Buzzard commented on my post “Molten Salt Energy Storage“: “Craig, do you know if a Stirling engine would be more efficient than making steam for a turbine?” To which I reply: I don’t know know much …
In response to my recent piece on solar thermal and molten salt, a reader admonishes: You assume that “molten” salt is universally available over the entire power grid? Get real! Apparently, I’m not describing this as clearly as I thought …
Recently, I spoke with Ben Beach, Senior Editor at the Wilderness Society. I reached out to Ben because I wanted to see how the organization was dealing with issue that public land (I presume some of it “wilderness”) is a …
My old friend Peter Buzzard writes: The current technology of Wind and Solar tends to provide power when and where it is needed the least. The transmission of power from wind and solar farms to population centers is extremely expensive, …

For my book on renewables, I just interviewed Brian Rutledge of the Audubon Society in Wyoming. I knew this would be an interesting talk, and I wasn’t disappointed. I spoke with Brian because I wanted to get a sense for …

I quoted Lou Schwartz of China Strategies in an earlier post on wind power, and I found what he said so fascinating that I placed a call to him just now to ask him more about his overall take on …
I deeply appreciate the growing rush of informed comments on the 2GreenEnergy blog. Frequent guest Arlene Allen (whom I had the pleasure to meet recently) writes: Normally, I would do my best to add something positive to the discussion. Quite …
What’s not to like about a $1.5 billion wind project covering 36,000-acre and generating the power for 180,000 homes in western Texas? For one, it rubs our nose in the fact that China is one of many countries that out-invests …
