Question

Fules and their efficiency in producing energy

Answer 1

Fuel efficiency means to do more with less. Efficiency is achieved by improving technology, so that less energy is consumed while getting the same or better results. A new automobile that gets better gas mileage without reducing power or performance is an example of how advances in technology can save energy by increasing efficiency, rather than relying on conservation (reduced performance or restricted use) as the only way to save energy.
