What is Energy Efficiency?
Energy efficiency is the process of using less energy to perform the same function. Energy efficiency aims to eliminate waste and extravagance. Energy-efficient homes and buildings use less energy to heat, cool, and power electronic devices. Similarly, energy-efficient manufacturing facilities use less energy to produce goods.
Energy efficiency provides a variety of benefits, including reducing greenhouse gas emissions, reducing energy import demand, and lowering costs for households and the economy as a whole. Renewable energy technologies also help achieve these goals. Improving energy efficiency is the cheapest and fastest way to reduce the use of fossil fuels. There are tremendous opportunities for efficiency improvements in every sector, whether it’s buildings, transportation, industry, or energy production. For example, energy-efficient LED bulbs can produce the same amount of light as incandescent bulbs while using 75 to 80 percent less electricity. Since energy production creates pollution and greenhouse gases, improving the energy efficiency of certain technologies has the potential to reduce emissions from the energy sector by significantly reducing energy consumption.
Energy efficiency is one of the easiest and most cost-effective ways to combat climate change, reduce energy costs for consumers, and increase business competitiveness. Energy efficiency is also a vital component of achieving net zero carbon dioxide emissions through decarbonization.
In short, energy efficiency saves money, increases the flexibility and reliability of the electrical grid, and provides benefits for the environment and public health.
1. Savings
You can save on your energy bills by making energy efficiency improvements that reduce your energy use and increase comfort at home, such as adding insulation, using LED lighting, and installing a heat pump. Energy-efficient buildings cost less to heat, cool, and operate. Energy-efficient transportation saves fuel.
2. Environmental Benefits
Reducing energy use is essential in combating climate change because conventional power plants burn fossil fuels that emit greenhouse gases and cause air pollution. Reducing fossil fuel use results in cleaner air, water, and soil, which directly impacts human health. Energy-efficient homes and buildings are better equipped to switch to renewable energy that does not produce harmful emissions.
3. Durability and Reliability
Energy efficiency improvements reduce grid load, or the amount of electricity, by minimizing grid congestion and stress. Less load prevents power outages.
Energy saving – the concept of reducing energy consumption by minimizing energy-consuming activities – is often confused with energy efficiency. The main difference between the two concepts can be summarized under three main headings;
1. Energy efficiency does not require you to change your habits.
Energy saving requires a certain degree of sacrifice, such as using the tumble dryer less often or turning down the heat in the winter. Energy efficiency, on the other hand, uses less energy while providing the same amount or quality of output/result. Instead of turning down the heat, you can install an efficient boiler to keep your home at a certain temperature while consuming less energy than a traditional boiler. Energy efficiency does not bother you with prohibitive restrictions and does not require you to change your behavior to reduce your electricity bills.
2. Energy efficient options are worth the investment.
Another misconception is that energy efficient options are not worth buying because they are more expensive than traditional alternatives. Yes, efficient options, whether they are home appliances or home features, often come with a high price tag. However, energy efficiency should be thought of as an investment that accumulates savings over time, rather than a typical purchase that is evaluated based on upfront costs.
When you upgrade to an energy-efficient system, the lifetime savings on your electricity bill have the potential to offset the total purchase price, creating a positive return on investment (ROI). Plus, a long-term energy-efficient upgrade/install can add value to your home after resale.
Traditional options offer lower upfront costs, but require more frequent replacements and create higher utility costs, reducing the benefits of the savings.
3. Big energy savings require an investment.
A common misconception about energy efficiency is that replacing just a few appliances will result in significant savings. To make significant savings, consider a holistic approach that strategically targets energy wasting sources in your home or business.
For example, the electricity consumed by appliances that are off or in standby mode, known as “phantom load,” can add $100-$200 to your annual utility bill. While your first instinct may be to replace the appliance with a more energy-efficient version, consider a smart power strip first. Smart power strips shut off when they detect that the appliances are not being used, effectively eliminating the phantom load from plugged-in devices.
Another example is installing an energy-efficient furnace or air conditioner. While installing an energy-efficient HVAC system can reduce your energy bills, if your home is not airtight or insulated enough, your savings will be less because it takes more energy to maintain any interior temperature.

Energy efficiency policies and technologies play a key role in reducing emissions. Energy efficiency measures are among the most cost-effective actions to reduce emissions. In IEA modelling, energy efficiency makes a major contribution to reducing global emissions. This contribution is, for example, by setting fuel economy standards in the transport sector, using efficient heat and steam technologies in industry, and by providing efficiency gains in all end-use sectors.
Strong energy efficiency policies are vital to mitigating climate change and air pollution, improving energy security, and increasing energy access. Mandatory energy efficiency policies and regulations, such as minimum energy performance standards and energy efficiency mandates, are delivering significant energy and emissions savings around the world.
While the cost of a holistic approach to energy efficiency may seem daunting, the savings and increased value of the building from such upgrades justify the entire investment.
Small changes can add up to big savings:
• Turn off lights when you’re not using them.
• Use energy-efficient LED bulbs.
• Unplug appliances when you’re not using them.
• Don’t put furniture in front of radiators.
• Don’t leave doors open in your building during the winter months and keep rooms you’re not using at low temperatures.
• Wait for food you take out of the freezer to thaw before cooking it.
• Don’t put hot food in the fridge right away.
• Don’t check on food cooking in the oven by constantly opening the oven door.
Energy efficiency measures enable us to create products, services and benefits at the lowest energy cost. And because energy efficiency reduces the amount of wasted energy, it provides many important benefits, including:
• The opportunity to delay or eliminate the need to build capacity with new types of facilities that keep electricity rates lower,
• Lower electricity bills for utility customers who participate in energy efficiency programs and lower rates for all customers,
• The opportunity to avoid grid curtailments, especially during peak hours, and increase grid reliability,
• Reduced environmental impacts,
• Local job creation and economic growth,
• Improved health, comfort and productivity for all citizens.
