Amazing how ice falling on people from wind turbines is as much a problem in Australia as the US.

Thanks for that, very interesting. The 1909 caption on the photo says the person is Cove, not Fritts, and that it is a 60W PV panel at 118 Maiden Lane, NY. The author of the 1884 claim sticks to his story on weird evidence (anonymous received postcoard). Seems like there may be more to uncover here.

And the solar-boiler powered water pump at the Cawston Ostrich Farm, South Pasadena, 1901 – I used to live around the corner.

Great idea! Here's Charles Fritts with his solar PV panel in New York, 1884 - supposedly 2% efficient. Definitely deserves a plaque .

Are there countries where renewable energy companies lobby their government for faster reductions in fossil CO2 emissions?

1983's famous "Real Programmers Don't Use Pascal": "Allegedly, one Real Programmer [from JPL] managed to tuck a pattern matching program into a few hundred bytes of unused memory in a Voyager spacecraft that searched for, located, and photographed a new moon of Jupiter." www.pbm.com/~lindahl/rea...

There is no rebound in emissions or energy use as EVs are far, far lower for both of these. A rebound in driving is best addressed separately (e.g. Blake Alcott, "Impact caps", www.sciencedirect.com/science/arti...) but arguably not even Norway is reducing transport emissions rapidly enough yet.

I would dispute that CO2/capita is falling "significantly" in most of the rich world. Just 1.4% per year in the past decade, and little sign of acceleration yet, not accounting for imports or international transport. Room for improvement.

Why is wind (relatively) slowing down – cost, opposition?
