Digital alarm clocks are plugged in the wall. Don’t they take a lot of elecricity ?
Aren’t regular alarm clocks better ? They don’t take electricity.
If your concern is to go green then yes get the old wind up type. They do not draw any power and never fail due to power outage. Consider though that you can run that digital clock ( without radio ) for an hour for what 1 standard light bulb burns in about 10 seconds. How about that electric garage door opener? You can run your clock for about a day for what that baby takes to just open the door. It’s important to keep things in perspective when taking about energy consumption.Coffee makers,ovens, hair dryers and such are the bad boys and will make your clock look like a VW to a sherman tank as far as power consumption goes.
