TV remotes? Agreed. The other two? You've got it wrong.Garage door remote control:
A gasoline car would use more energy idling while the driver got out to open or close the garage door than the 500W electric motor needs to do the job (and the small draw at all other times does not make up the difference). Even for a Nissan LEAF, the vehicle uses more than 500W just to sit there, so it would use more energy due to the additional time the energy was being used.Microwave oven:
Even though a microwave oven only has a real-world energy efficiency of about 50% (AC electrical power to microwave power) and the heating element of an electric oven or electric cooktop has an energy efficiency of 100% (AC electrical power to heat), the microwave oven is more efficient for nearly every small food-heating task than an electric cooktop or an electric oven or even an electric toaster oven. The reason is that the microwaves in a microwave oven heats the food directly while the electric heating element in an oven or cooktop heats something else which then heats the food. As a result, the microwave oven saves energy two ways: It heats less material and therefore heats for less time. The simple reality is that a microwave oven can tackle some tasks such as baking a single potato with about ONE-FORTH as much energy as a traditional oven.
So, yeah, microwave ovens and garage door openers would exist even if they did not offer any additional convenience.
But electrifying transportation in the US (or the world) will require a massive increase in electricity generation. That additional electricity will not come easily, cheaply, or without significant damage to the environment. As such, lossy solutions will be limited to a small fraction of the overall transportation solution. Because of the challenges we face as we move toward electrification will preclude (prevent) inefficient solutions from achieving significant fractions of the market.
As everyone can clearly see with the hydrogen fiasco, even massive government subsidies do not change this reality.
