Just because your swing isn’t a home run doesn’t mean you shouldn’t take the swing.
Let me give you an example. Just because it is not sunny all day, every day doesn’t mean you should not invest in a solar panel system for your home. It also isn’t always windy. Maybe the tides aren’t going to … never mind that one.
Maybe society can’t generate ALL their power through solar or wind or tidal power, but they can generate SOME of their power. Maybe some communities can reduce their reliance on fossil fuel generated energy.
Just because your idea isn’t a be all solution, doesn’t mean you should give up on it.
After all, some famous hockey player they called The Great One said, “You miss 100% of the shots you don’t take.”
Take the shot. Maybe your energy savings idea will be the start of something that grows into an international movement.
