I think the 80% number is outdated (although most of the energy is still wasted)

F1 engines achieve a peak thermal efficiency above 50 percent, significantly higher than a modern passenger car’s 35 percent thermal efficiency - https://www.motor1.com/news/655596/video-how-f1-engines-make-1000hp/

So more like 65% goes out the tailpipe…

Why would you have 30 days in those months? I’m a fan of having exactly 4 weeks each month (28 days), across 13 months. Then every month is the same. If the 1st is on a Monday, then the 1st of every month will always be a Monday. You just need to add a leap week in every now and again.

Fixing a leaky tap isn’t going to help much during a flood. I don’t know the numbers to be making any kind of judgement call and of course every little bit help. But sometimes a small issue really is so insignificant that fixing it has no noticeable impact in the bigger picture.

Often it can even be a great way for companies to look like their doing something to help and distract from the fact that they’re the ones causing the bigger problem.
