Energy Efficiency

About energy efficiency

Alongside renewable energy, energy efficiency is the other foundation of ‘sustainable energy' that is essential in helping reduce total CO₂ emissions.

While renewable energy describes energy that is unlimited and not from the combustion of fossil fuels, energy efficiency is the measure that is essential for slowing down energy demand and ensuring that it is not overused.

As it is primarily concerned with reducing energy demand growth, it ensures that renewable energy development isn't chasing an ever-increasing target.

Examples of energy efficiency

Energy-efficient products or systems are those that are designed to use less energy for the same or higher performance than regular products or systems, and energy-efficient buildings are designed to use less energy than traditional buildings.

Some examples of energy efficient measures include:

• Cavity wall insulation
• Loft and floor insulation
• Energy efficient windows
• Insulated doors
• Heat recovery ventilation (reclaiming the heat from warm air exiting a building, and pre-heating fresh air that is entering).
• Energy-efficient lighting
• A-rated electrical appliances
• Turning off equipment when not in use
