In 2000 I lived in Los Angeles in an air conditioned house (power bill >$100/month), drove to work every day consuming at least three gallons of gas, the computers I worked on consumed ~100-200 watts, and all my lights were incandescent. In 2019 I lived in Bangkok in a (very-lightly) air conditioned apartment (power bill $15/month), walked to work, the computer I worked on consumed maybe 60 watts, and all my lights were LED. I've since moved to Seattle and the power bill has gone back up, but I'm working remotely on another ~60 watt computer, and the next will be ~20 watts. The trend is in the right direction.
