Energy Efficiency FAQs

Living in a hectic city like Sydney is energy-demanding, but worry less as you can advocate energy-efficient living. With the depleting resources for fuels, efficiency in your energy usage is not an option but has become a necessity.

Furthermore, many people consider energy efficiency as an avenue to save energy and money. In a broader sense, there’s more than that which entices all energy consumers. On that, here are the 10 frequently asked questions on energy efficiency:

1. What is energy efficiency?

Energy efficiency is the measure of energy productivity of any service or goods. When there’s lesser energy needed to produce an output, the activity is then considered energy-efficient. It is also associated with energy intensity, which is commonly used as a measurement in economic goods and service industries.

2. How energy-efficiency improves over time?

Energy-efficiency will improve when both our technology and economy go at a more advanced pace. For instance, improved energy-efficiency indicates using less gasoline to drive the same amount of miles. It’s also connected with improving thermal efficiency as power plants generate more electricity with less fuel.

Moreover, it improves with the emerging energy-efficient technologies such as the transition from kerosene and incandescent bulbs to compact fluorescents and LEDs. Overall, energy efficiency is an indicator of long-term economic growth in energy-intensive sectors.

3. Who can offer energy efficiency activities?

Accredited Service Providers (ASPs) are businesses authorised to offer energy efficiency operations. They can provide discounted energy-saving services and products to residential customers. These businesses also work with third-party installers such as electricians and air conditioning technicians.

4. Is it compulsory to upgrade our home to energy-efficient products?

No, the NSW government won’t require you to upgrade your home with energy-efficient products. Like any other consumer decision-making, the choice is solely on you in selecting the energy-consuming products you must have at home. But it’s an advantage to have energy-efficient products as it utilises energy at an optimal rate for a low cost.

5. What difference does replacing a regular light bulb with an energy-saving bulb can make?

Replacing your old light bulb with LED light bulbs can prevent 1,000 pounds of carbon dioxide from being emitted to the atmosphere from power plants. Also, energy-efficient LED bulbs can last for more than a decade, helping you save hundreds of dollars throughout the bulb’s lifetime.

6. How do LED bulbs become very energy-efficient compared to other bulbs?

LED bulbs convert less energy into heat, and it’s noticeable as they don’t get hot. It illuminates bright light due to the movement of electrons in its semiconductor materials. The semiconductor exhibits both properties of conductor and insulator that results in the high efficiency of the bulb compared to regular bulbs.

7. Is it too late to make a difference through energy efficiency as conservation measures against global warming?

It can never be too late to make a massive difference in stopping global warming. If we get serious with our energy efficiency practices, we can lower the energy cost, which means reducing the exhaustion of the resources and greenhouse emissions. With that collective effort, we can make a significant impact on ending global warming.

8. Does the energy star label in products signify energy efficiency?

Yes. Products bearing star labels indicate a more energy-efficient performance than standard products, thereby saving money and energy. The energy star certified products include appliances, HVAC equipment, lighting, and office machines. Using these products can slash 30 per cent energy cost in your home or commercial space.

9. How can I become energy-efficient without spending a large sum of money?

Most people often think that an energy-efficient living is achievable with upgrades in appliances and the use of solar panels. But it is not always the case. You can be energy-efficient by using energy in a disciplined and effective manner.

For example, you can turn off the lights when not in use and be smart on how to use appliances to save energy. Your initiative for wiser energy use has the same sense of energy efficiency—utilising lesser power in creating an output.

10. What are the indirect benefits of energy efficiency projects?

It might be surprising that energy-efficient projects contribute to increased health, less stress and better productivity. Old technologies often are noisy, smelly and break down quickly, which is annoying and stressful. 

But energy-efficient technologies solved these issues. It helps your home far from any noise and electrical hazards, thus creating a safer and comfortable environment. In effect, people perform better with no worries from smaller electrical bills.


People need to raise questions, most importantly, when it comes to utilising energy efficiently. Most people sought energy-efficient technologies to save energy and money. In the longer term, energy efficiency helps people conserve resources and environment.
