When I think of the places on the planet that seem optimized for solar and wind power generation, I think of deserts like the Sahara and the desert Southwest in the US. And yet Germany is generating a growing share of its electricity through these renewables:“Preliminary data by energy market research group AG Energiebilanzen (AGEB) showed that onshore wind turbines produced a record 114.2 terawatt hours (TWh) in Germany in 2023, while solar PV...

Graph 1. The increasingly inefficient use of carsSummary: parking places are a woefully inefficient use of space. And ugly. Cars are a woefully inefficient use of machinery. Using them, in combination with bi-directional charging of cars, to produce solar can amend this. Doing this the right way, parking places can be beautified, costs will go down and life will be more pleasant. A typical car is, like a washing machine, a household appliance. As such, they are woefully...

Like many others, we use Costco to buy bulk things or special items such as this new screen I have plugged my laptop into. This morning, I am looking at the myriad of emails (many of the junk) and clicked on the latest Costco addy to see what they are hawking. Voila . . . a solar powered generator. This one is made by Anker (of phone battery charging fame), sold at Costco, and at a discounted price of ~$3700. There are some issues with...

Researchers found that PV systems could produce electricity at a lower price than the grid in 344 cities. Good news for air quality and climate. China has been relying on coal-fired plants (72% in 2016). Two anecdotes. I have a friend that teaches for six-weeks in Beijing on occasion. I once said to him that it must be a great experience. He answered that it was terrible, the pollution was so bad. I have another acquaintance that is Chinese, now living in the US. He's been here about 20...

A new bill backed by MidAmerican Energy would devastate the ability of Iowans to install solar panels for their homes or businesses. House Study Bill 185 would undo a longstanding policy of net metering, which “allows residential and commercial customers who generate their own electricity from solar power to feed electricity they do not use back into the grid.”Iowans served by monopoly providers MidAmerican or Alliant Energy have been able to use net metering since the 1980s, under rules...
