And this is kind of an example of why it will be impossible to mitigate Climate Change.
When I was young, clocks did not requite any power from the grid. It wound them, set the alarm and you heard it. Now we have faucets, toilets that use power to turn on/off and flush. Almost everything that was manual (mechanical) is now powered. That power needs to come from somewhere. In these examples, there is no real reason to have faucets, toilets and alarm clocks connected to the grid.
Yes, I know in the case of the Cell Phone Alarm, it is probably a wash, but a mechanical clock in your house is probably a good thing to have.
