Art Rosenfeld passed away two weeks ago. Most people would not remember him, but they have been affected by his simple observation in 1976 that a “proposed nuclear power plant would not be needed if refrigerators were required to be more efficient.”
Here you can see the effects on the energy efficiency in the state of California:
Note how the energy expenditure per capita flatlines from the time he made the observation above. It was never one thing, but a lot of little things Turning off lights at night, higher efficiency furnaces and fridges and stoves. Higher efficiency lighting. Better windows.
These are the kinds of things which make a huge difference in aggregate (and he was a master at expressing how much of a difference each of them would make singularly, such as spending 20mins with light switches saves 100 gallons of gas over the weekend). These are the kinds of incremental changes which are slowly reducing the scourge of cancer. These are the kinds of things which can reduce changes to the climate.
Thanks, Art. Let’s keep working and doing things a little more intelligently every day.
