Energy Wastage in Hong Kong
Focus: household energy consumption

Solar panels
Did you know that people this year are consuming nearly twice as much energy as they were 30 years ago? If we continue to use energy at such high rates, reserves of non-renewable energy may run out really soon. In order to prevent this people must make small changes by using less energy in their daily lives. Even the smallest action can have an impact on the rest of the world. An example of using less energy is as simple as unplugging your recharger from the socket when your not using it. Most of the energy wastage comes from homes and a lot of the times it’s when we’re doing nothing. Energy wastage occurs very often at home, leaving computers and televisions on standby, using a thick blanket with the air conditioning on 16˚C, leaving the bathroom light on during the night, all require quite a large amount of electricity. However there are alternates to all of those things, many ways we can reduce the amount of energy wastage at home. Everything people do is interconnected and has it’s own consequences, everyone might be self sufficient in energy resources but the impact of the energy wastage affects the whole world.

What appliances cause this and how can we stop it

So what appliances waste the most energy? Studies have shown that heating and cooling facilities in homes are definitely the highest energy users. With the highest annual average household producing about four tons of heat-trapping pollution, the usage of this appliance heavily relies on the weather. Colder years lead to an increase in emission, while warmer seasons helped dip a bit. However at the same time hot summers increase fossil fuels pollution too because of an excess use of air conditioning. All year around, many people still set their air conditioners at too low of a temperature and sleep with thick covers. The solution is simple; reduce the amount of cooling and heating air use around the year. Instead of using an air conditioner, a fan produces less energy, or opening the windows on a breezy day could quickly decrease our body temperature. During the winter, have the blinds up for the sunlight to warm the house up, and use solar water heaters. Studies show that solar water heaters save people more than $500 US a year on energy bills, and works the same as a normal heater. Energy Star

After heating and cooling, freezers and refrigerators are a home’s next two large energy consumers. These appliances often consume almost eight tons of heat-trapping emission per year. A widely recommended brand is Energy Start products; these are often the best energy saving appliances chosen from different places. Another reminder when shopping for multiple appliances is the size. Even though it might look better, a larger than necessary appliance could waste electricity, which then increases energy costs. A lot of people think that when your not using that appliance, leaving it plugged does not generate energy. However, it does, your electric meter is often adding up kilowatt-hours when it’s just idle. Unplugging toasters and cell phone chargers could quickly save a lot of energy and money, it is also better not to buy plug-in air fresheners.

An energy efficient light bulb

The third biggest energy eater is lighting, and every year, lighting takes up just over a ton of carbon dioxide. A highly effective way is to change your light bulbs to more efficient ones. This means that instead of using an incandescent 100 watts light bulb, a similar light bulb produces the same amount of light only using 15 watts. Well, how is this a benefit? Changing only one 100-watt bulb into a fluorescent one cuts around 1,300 pounds of global warming pollution. On top of that, they last 15 times as long, and you...
