“The grid can’t handle electric cars.” That statement checks out, if you’re bad at math. You see, Americans drive their cars about 3 trillion miles per year. EVs use about 0.337 kWh per mile, meaning total energy demand would be 1 trillion kWh annually. Factoring in transmission and charging losses, that rises to 1.25 trillion kWh. Since the U.S. already produces 4 trillion kWh per year, fully switching to EVs would require just 31% more energy. Historically, U.S. electricity production grew 1,100% from 1950 to 2005, averaging 4.6% yearly growth. At that rate, we could meet EV demand in just six years—incredible, especially considering that a consumer shift to fully electric would easily take decades. The grid will need updates, sure, but history proves it’s easily possible. The U.S. energy grid: able to handle millions of air conditioners on a summer afternoon, but somehow collapses at the thought of an EV charging overnight.

Energy Math:
3 Trillion Miles * 0.337 kWh/mi = 1 trillion kWh
1 trillion kWh / [92% (transmission η) * 86% (charging η)] = 1.25 trillion kWh
1.25T kWh / 4T kWh = 31%

Percentage Increase:
Electricity production in 1950: 335 billion kWh
Electricity production in 2005: 4056 billion kWh
Percentage Increase: (4056/335)/335 = 11.107*100 ≈ 1100%

Increase Per Year = 4.63859%
Math: 1.0463859^55*335 = 4056 (1950 – 2005)

6 Year Math:
1.0463859^6 = 1.3126 = 31.26% increase.
Needed increase to meet US EV demand? 31.25% (1.25T/4.0T kWh)
