More Efficient EVs Would Be Cheaper, Less Stressful On Power Grid

• The American Council for an Energy-Efficient Economy (ACEEE) says that a more efficient battery could cut EV costs by up to $4,800 and charging times by a third.
• Smaller batteries and more efficient EVs could cut demand on the power grid by 20%.
• The ACEEE proposes the EPA to consider upstream CO2 production in a vehicle's battery pack as a way to incentivize automakers to focus on vehicle efficiency.

It’s easy to forget that electric cars are remarkably efficient. Unlike any combustion-based engine in which the potential energy from its fuel is lost mostly via heat and friction, electric motors convert most of their energy into forward motion. Just think of it this way: A 6,300-lb Ford F-150 Lightning can travel 320 miles on the energy equivalent of about four gallons of gasoline.
