This is done by investing in more efficient motors, light bulbs and other devices that use electricity.

Manufacturers are delivering more efficient motors, but they're also focusing on features that are just as important to users of all skill levels.

From this he showed that the most efficient motors are likely to be relatively large.

In 1919, Evinrude invented a more efficient and lighter two-cylinder motor.

(For main article, see: Copper in energy efficient motors).

The most efficient motors exceed 98% efficiency.

This, the Florida scientists report in the journal Nano Letters, should make for a more efficient motor.

Investing a little more money upfront for a more efficient motor is often paid back in energy savings.

Brushed electric motors and more efficient brushless motors are used.
