I recently heard about a new app called Light Bulb Finder that will let you figure out how to replace your incandescent light bulbs with more efficient technology as well as how much money you will save in your electricity bills. It put me in mid of a recent revelation of how smartphones have also made plugging into an EV charging network a very different experience than in the 1990s.
