Frequently Asked Questions on Energy Efficiency and Conservation and Renewable Energy
1. What is energy efficiency and conservation?
Energy conservation means using less energy by changing behavior such as turning your lights off. While energy efficiency means using energy more effectively with the help of technological change. Energy efficiency measures the difference between how much energy is used to provide the same level of comfort, performance or convenience by the same type of services.
2. How does my electricity get to your house?
The figure below can explain how you get your electricity:
3. Which sectors (government, commercial, industries and residential) that consumed more electricity?
Residential consumed more electricity than the other sector which is 48 percent, followed by commercial 25 percent, government buildings by 17 percent and industries with 10 percent.
4. Why do we need to conserve energy?
We need to conserve energy because we need to prevent running out of resources and make them last longer for our next generations. Apart from that, we also can help to reduce the global warming.
5. How I can help to conserve energy?
It might seem like we cannot do much to help. But every time you turn off a light or close the refrigerator door, you are saving energy. You can also help by reminding your family to buy energy efficient appliances.
6. Which electrical appliances that consumed much energy in my house?
Based on the study made by Centre for Strategic and Policy Studies (CSPS), about 61 percent of your electricity is consumed by air-conditioner and 11 percent consumed by kitchen appliances such as refrigerators, microwave ovens and other appliances.
7. What is Renewable Energy?
Renewable energy comes from natural processes that are continuously replenished at a faster rate than they are consumed. Solar, wind, geothermal, hydro, and some forms of biomass are common sources of renewable energy.
8. How much of the world's energy comes from renewable sources?
According to International Energy Agency statistics, Renewables accounted for 19.5 percent of global electricity generation in 2009.
