For example, I took this shot of my shower head right when the hot water was starting to flow. The hot water shows red and the everything else shows blue. The scale on the right side shows the hottest (103.8F) and coldest (76.8F) temperatures the camera captured with a color scale in between.
If you didn't ask for it, Heat = WasteThe whole point of a car is to move people from place to place. Unless you need heat to keep you warm along the way, any heat the car makes is wasted energy (fuel). Why? Because heat doesn't directly power your wheels...it's a necessary evil in an Internal Combustion Engine (ICE) that relies on explosions to work.
Given that conventional gasoline vehicles only convert about 20% of the energy stored in gasoline to power at the wheels, it follows that when gasoline is $5/gallon, $1 goes toward getting you to your destination and $4 goes to heat the earth. Stupid eh?
EVs, on the other hand, convert about 60% of the electrical energy from the grid to power at the wheels. That's a 3x efficiency...and EVs can recover even more energy with regenerative braking.
