I used blow dryer two times a day, in the morning and at night. I use it after I washed my hair. The duration of usage is about five minutes each time, which means that I use it about 10 minutes a day. The power rating of blow dryers are high, which is 1500 W. That is to say, when this kind of device is turned on, it consumes a lot of energy. Therefore, I decided to stop using blow dryer for three days.
In three days, I don’t feel that my life was influenced in a great deal. Actually, even without using blow dryers, my hair dried fast. After I did some research and calculations, I found that if I use blow dryer 10 minutes per day, the energy blow dryer consumes will be 0.9 kwh per day. If I multiply this number by 365 days per year, the energy that blow dryer consumes will be 328.5 kwh per year. The world’s average household electricity use is about 3,471 kwh per year. By comparing these two numbers I found that if I use blow dryer 10 minutes per day, the energy that blow dryer consumes is equal to 1/10 of the world’s average household electricity use. This is just the energy consumed by using blow dryer 10 minutes per day in a year. From this experience, I learned that some changes of our behaviors in our lives can have an observable influence on the environment and world’s total energy consumption.
Changing our own consumption habits can have some impact on the global condition. However, it is not enough. The greatest impact comes from industries. When the factories are producing products, wastes are also released. When power plants are generating power, greenhouse gasses are released. To really make a great impact on the global condition, we must set more regulations, controlling the waste release. Moreover, we must to do more research, finding a way to produce products without releasing wastes that harm environment. We also have to replace fossil fuels with clean energy resources. This may seem hard to achieve, but this is how we can really make some big changes.
