Energy efficiency – in cars and ourselves

A few years ago, there was confusion about why electric cars were better than ICEs or internal combustion engine/gas powered/petrol powered cars. The reason for the confusion was around the assumption that these cars needed a fossil-fuel powered grid to charge themselves.

Of course, EVs become SO much better for the environment as we continue to transition to a renewable based grid (more here).

But that’s not all. 9 out of 10 units of energy used to charge an electric vehicle is used to drive the vehicle vs. 2 out of 10 for a petrol car. That’s 450% more efficiency.

This got me thinking about our energy conversion as humans.

For every unit of energy we take in, how much actually goes into meaningful output? And how much goes into avoidable drama, politics, frustration, and angst?

Take inspiration from electric vehicles, we must.
