Fact of the week: Internal combustion cars still waste 70 to 88 percent of energy

Conventional cars manage better fuel economy every year.

According to the latest Department of Energy “Fact of the Week,” though, their efficiency ranges from a-little-better-than-before to still-abysmal.

This week, the DOE noted that of all the energy splashed into a conventional car’s gas tank, only 12 to 30 percent actually goes to move the car down the road.

Everything else is lost to engine inefficiencies, heat, or used to power accessories, the DOE says.
