Reader Falsely Claims Renewable Energy Horribly Expensive
Regarding the cost of renewable energy, a reader notes: First mistake? Not calculating the ENTIRE life time cost of wind farms, solar farms and so on. It costs more, MUCH more to produce energy from so-called “renewable” sources, than it does …

Validity of Wind Energy
An old school chum shared this piece of excrement on Facebook just now, to which I responded: It pains me greatly to see disinformation like this spread around.
Renewable Energy Products that Cause Embarrassment To the Industry
One of the challenges facing solar and wind energy is capacity factor, i.e. the ratio of the total energy generated by a device to the total energy that it’s potentially capable of generating (multiplied by 100, to make a percentage). …

Environmental Benefits of Wind
I’m part of a large email group that promotes the concept of “advanced nuclear.” Most of these people are extremely well-informed, intelligent, and kind people. Some, however, have a bizarre hatred for renewables, like the guy who started this conversation: …
Does Wind Energy Require More Energy to Build, Install and Maintain Than It Produces?
I wrote a post earlier in which I pointed out that solar and wind are valid energy resources even though they are variable. In response, a reader writes: Craig, have you ever looked into the CO2 burden that wind has …
