Energy efficiency means using less energy to do the same job, reducing energy bills and pollution.
Wherever energy is used, there is an opportunity to improve its efficiency. Some products, such as energy-efficient light bulbs, simply use less energy to produce the same amount of light (consuming up to 90 per cent less energy than an incandescent bulb while still providing the same illumination). Other products do not use energy directly, but improve the overall efficiency and comfort of a house or building, such as thermal insulation or windows.


Most switches and sockets draw their electricity from nearby power plants. These power plants typically burn fossil fuels, such as natural gas and coal, which cause the greenhouse effect and contribute to climate change.
By using energy more efficiently, we can help reduce emissions of greenhouse gases and other air pollutants, combat the threat of climate change, and protect our health and the environment.


By reducing energy consumption, energy efficiency reduces monthly bills and makes energy cheaper for businesses and households.
It should be noted that some energy-efficient products cost more than other options, but they generally save money in the long run, offsetting the initial cost with ongoing savings in energy bills, reducing energy costs for consumers and businesses.

In short, many products, homes and buildings use more energy than they need, due to energy inefficiency and waste. Energy efficiency is one of the easiest ways to eliminate this waste and reduce energy costs, while also combating climate change.
