Energy-efficiency is the practice of lowering energy consumption by using less energy to obtain the same quantity of output. Commercial buildings, industrial facilities, and households often use more energy than is needed.
Environmental awareness is extremely important. This is because environmental problems appear as external costs that are not normally reflected in the price that consumers pay for. The electricity sector is responsible for around 25% of human-caused greenhouse gases (GHG) emissions per year. Adopting energy-efficient practices and using renewable sources of energy can positively affect the future of our planet. The most important environmental benefits of using energy-efficient appliances are that they mitigate:
