Summary The synchronous motor: 1. requires to be started by an external prime mover. 2. Runs only at synchronous speed, this is an advantage where continuous speed is required but a disadvantage where a variable speed is required. 3. Can be used to adjust the power factor of a system at the same time it is driving a mechanical load. 41.

September 8, 2022 by Brian Wang. Assuming each EV travels 12,000 miles annually, consuming approximately 300 Wh/mi of AC energy and assuming 4.9 % system losses for transmission and distribution, then each EV will require 3.8 MWh/year of energy generation. If there were 10 million EVs in California then they would need 28 TWh/year.

If we convert sunlight to electricity at 15% efficiency, and wind at 45% efficiency (typical numbers), we have 30 W vs. 3.5 W. Solar beats wind (in that same location) by an order of magnitude. Comparing optimal solar sites to optimal wind sites (taking 1000 W/m² by rotor area), solar wins by a factor of five.
