Energy efficiency rise as one of the main problems in the world. The energy consumption all around the world has been soaring so fast each year that it causes an increase in carbon pollution leading to extreme climate change. This jeopardizes the earth’s natural resources and habitats causing dangers to all living things including human beings.

The key to combat this climate change and to have a safer and sustainable energy system is energy efficiency. It could quickly resolve the vast energy consumption at home and other sectors.

In addition, it could improve the environment and economy of each nation by reducing the energy costs of consumers, enhancing the business sectors and cleaning the air that people breathe. To understand more about the efficiency of energy, here are some details about it.

1. Defining Energy Efficiency

Energy efficiency is the productive and economic use of energy. It aims to reduce the amount of energy, yet deliver the same amount of services.

One example of this is the traditional incandescent light bulb that provides light but emits much heat loss. By replacing this with an energy-efficient light bulb, there will be the same amount of light and no heat loss. In addition, it uses less energy.

2. Its Benefits

  • It reduces greenhouse gas emissions. This could aid in managing the emissions of gases all around the world and improve climate change.
  • It lowers energy costs. With efficiency, less energy is wasted. This means that only a few kilowatt-hours will reflect on your electric bill and you could save money.  
  • It enhances the sustainability of the energy system. Energy efficiency could meet the demand for energy including oil, coal, gas or renewable for any sectors.
  • It promotes healthy well-being. The air that people breathe will be cleansed with the productive use of energy, which emits fewer gases in the atmosphere. This could prevent air pollution, which is damaging to the health of many people.
  • It improves production in the industrial sector. The efficiency could cut energy wastages and costs. This could reduce the industries’ expenses and help in their advancement and accumulation.

3. Energy Efficient Appliances

Modern energy-efficient appliances like dishwashers, ovens, stoves, freezers, air conditioners, refrigerators, washing machines, and dryers, among others, could use less energy than the old appliances. In addition to reducing energy consumption, it is advisable that you turn them off when not in use or utilise them in low energy mode.

4. Energy Efficiency and Energy Conservation

Energy efficiency differs from energy conservation though they both aim to reduce energy consumption. In efficiency, you will use the product and have the same output, yet use less energy. Meanwhile, in conservation, you are reducing energy consumption by not using the product or using it less.

An example of this is walking in the supermarket nearby rather than using a car or using a clothesline to dry your clothes than using a dryer or simply turning off the lights or the appliances.

In Singapore

The Singaporean government has been undertaking initiatives to achieve effective energy usage. It has the following energy efficiency strategies:

  1. Planning and promoting Singapore’s greenhouse gas emissions and mitigation plan to improve the efficiency of energy.
  2. Taking energy efficiency initiatives for household, public, and industrial sectors.
  3. Disseminating information and raise awareness among the home sector as well as the public and industry.
  4. Enhancing and supporting research to improve the energy efficiency technology in Singapore.

Likewise, the National Environment Agency (NEA) and the Energy Market Authority (EMA) in Singapore are also aiming for effective energy usage for the home sector, public sector, and industry sector. These include reducing gas emissions through utilising less carbon-intensive fuels. They also advocate and build up energy efficiency through disseminating information in public education, legislation, and incentives.

Energy Efficient Labels in Singapore

The suppliers of certain goods and appliances must put the Energy Label on the units, which tell how energy efficient are the units by using ticks. This must be implemented after the National Environment Agency (NEA) has provided the Certification of Registration for the unit.

The ticks rating system works in this way for an air conditioner, television, clothes dryer, and refrigerator:

Ticks Energy Efficient
1 Low
2 Fair
3 Good
4 Very Good
5 Excellent

The energy-efficient labels on the appliances could guide the customers in what units consume less energy. With this, they could reduce the use of energy and save money. Likewise, these labels could motivate industries or businesses to develop more energy-efficient products.
