If you don’t care how much you pay for electricity, and you don’t mind having your neighbors think you’re a moron, this is a great idea.

Solar Thermal
When 2GreenEnergy was launched in 2009, the concept shown at left, “solar thermal,” held great promise. The main reason for optimism lay in its integrated storage, i.e., molten salt, which could take on energy, raising its temperature, and then give …

Transparent Solar PV
This is theoretically possible; it transmits visible light and uses other frequencies (ultra-violet and infrared) to knock electrons out of the substrate. But it means higher costs and lower efficiencies. Of zero practical value at this point.

Solar PV as Windows
A reader asked me about the supposed breakthrough in making PV solar panels transparent, so they can replace windows in office buildings. I don’t believe this. PV works by absorbing photons and using them to knock loose electrons from a …
Americans Hate European Socialism
Good point here. We regard the German people of the early 20th Century as willfully ignorant. That’s certainly not good, but it’s far better that today’s Trump supporters, who openly welcome authoritarianism, as it gets them what they want: white …
Beaming Solar Energy to Earth from Space
Many of us have seen the illustration here, where a solar PV array is put into a geosynchronous orbit, and sends microwave energy to a collector on earth. There is nothing theoretically impossible about the idea, and one good thing …

Solar PV Meme — More Clickbait for Morons
There is 23,000 times more farmland in America than there is solar PV on farmland. In addition, there are clever ways to integrate solar with agriculture, called “agrivoltaics.”
Solar and Wind Are Intermittent Resources — More
Are we to believe that “Burgum” on Fox Business is unaware that millions of people all around the world have perfectly reliable power using only solar energy? This is just one more lie told to an ignorant audience.

True, Solar and Wind Are Intermittent Resources
Many of us can remember the early days of renewable energy, and our concern that resources like solar and wind were intermittent. Could such energy sources offer value even though they are not “baseload?” Well, thirty years later grid operators …
