The term 'energy efficiency' is often used as an abbreviation to describe any kind of energy-saving measure. Efficient energy is the goal to reduce the amount of energy required to provide products and services. In this emerging market of cleaner renewable decarbonizing fuels, improving energy efficiency is an essential tool in the reduction of CO2 emissions, alongside energy conservation and low-carbon energy sources such as renewables and carbon capture and storage. We’re taking responsible steps to cut carbon pollution and fight climate change.
