I love blue blue BLUE sky! :)

Using less, getting more
Conserving energy does not mean changing your lifestyle drastically. You do not need to read under moonlight or take cold showers just to save electricity. Instead, energy conservation today is all about energy efficiency: doing the same things with ust a fraction of the energy. It is about doing more with less.

How climate change affects us.
Climate change is not only a problem for polar bears. Every singaporean should be concerned. Here is what we face:
- Rise in sea level
- Hotter days and nights
- Higher food prices due to climate change in countries we import food from
- Change of weather patterns, such as more frequent heavy rainfall
- Resurgence and spread of infectious diseases

Why is our climate changing?
All of us are responsible for this! Every time we switch on an electrical appliance, we contribute to climate change. That is because in Singapore, electricity is generated mainly by burning fossil fuels, which produces carbon dioxide or CO2. Excess CO2 in the air traps more heat from the sun, causing climate change.

5 simple steps on how to save your home electricity consumed.
The air-conditioner uses the bulk of the electricity in a home. A fan uses less than 1/10th the electricity used by an air-conditioner! Use a fan instead of an air-conditioner to keep cool. You can use three fans to keep cool and you would be using only about a quarter of the electricity used by an air-conditioner! The lower the temperature setting, the more energy used by your air-conditioner. If you use an air-conditioner, set the temperature at 25oC or higher. The energy consumption by the air-conditioning unit increases with the difference between the room and outdoor temperatures.

Switch off home appliances at the power socket. Do not leave them on standby. After switching off your appliances (e.g. televisions, computers, printers, VCD, DVD and CD players) with the remote control, many of them continue to draw power. Standby power can account for up to 10% of your home electricity use. To reduce standby power, turn off these appliances at the power socket.

Using a compact fluorescent lamp (7W) instead of an incandescent bulb (40W). Choose energy efficient light bulbs (e.g. compact fluorescent lamps). Compact fluorescent lamps (CFLs) use up to 80% less electricity than incandescent light bulbs to produce the same amount of light, and they can last up to 10 times longer! This means you do not have to buy and replace light bulbs as frequently. Where you would use a 100W incandescent light bulb, you would only need a 20-25W CFL.

Choose an energy-efficient appliance (e.g. air-conditioner. refrigerator) by checking the energy labels. The energy label found in all refrigerators and air-conditioners at the point of sale helps you identify and select an energy efficient model that suits your needs. The more ticks, the more energy efficient the model is.
