What is energy efficiency?

To perform a task or achieve a goal while using less energy is known as energy efficiency. Energy-efficient homes, buildings, manufacturing facilities, and electronics use less energy to produce goods and less energy to heat, cool, and operate appliances and electronics.

One of the simplest and most affordable strategies for halting climate change, lowering consumer energy costs, and boosting the competitiveness of American companies is energy efficiency. Achieving net-zero carbon dioxide emissions through decarbonization depends on energy efficiency as well.

The Office of Energy Efficiency and Renewable Energy (EERE) supports clean energy through its technical offices and programs that support research and development and encourage energy efficiency in all facets of the American economy.

Energy efficiency = useful energy output/energy input × 100%

useful energy output = 250 watts

energy input = useful energy output + waste energy ouputs

= 250 + 600

= 850 watts

Energy efficiency = (250 /850) × 100%

= 29%
