Three examples of electromagnetic energy are visible light, radio waves, and X-rays.
Three examples of objects in motion that exhibit kinetic energy are a moving car, a swinging pendulum, and a flying airplane.
Energy efficiency compares the energy output of a system to its energy input. It indicates how much of the input energy is converted into useful output energy, with higher efficiency values indicating less energy wasted.
Energy efficiency is typically calculated as the ratio of useful energy output to total energy input. The equation to calculate energy efficiency is: Energy Efficiency = (Useful Energy Output / Total Energy Input) x 100%.
British Energy Efficiency Federation was created in 1996.

Oil,Coal,and Fossil Fuels
The three gorges damn, Hoover damn
If it is burned - which is the way such fuels are usually used - the energy efficiency is the energy efficiency of a heat engine. The theoretical maximum efficiency is the Carnot efficiency; the real efficiency will usually be considerably less than that.
Thermal insulation of walls and ceilings, double or triple glazing of windows
Three examples of stored energy from photosynthesis are glucose, starch, and cellulose. These molecules store energy in the form of chemical bonds, which can be broken down through cellular respiration to release energy for various metabolic processes.
