Electric motors are in general, a lot more efficient that internal combustion engines. An average combustion engine has about 18â20%. A formula one engine, has about 50% of an efficiency.
Being energy efficient means doing the same amount of work while using less energy. For example, an energy efficient washing machine provides the same service, laundry, but at a lower rate of energy consumption.Similarly, a well-insulated house is more energy efficient because less heat escapes and therefore less heat needs to be used to maintain a comfortable living environment.or example, an energy efficient washing machine provides the same service, laundry, but at a lower rate of energy consumption.
