Comfortable and ecological life with Energy Saving DIY



Energy-Saving DIY
simply means turning your house into an energy-saving specification with only minimal effort. There are many useful goods at home improvement centers that you can visit to check out some items to help you do this. This winter, switch things up by trying some energy-saving DIY options.


First, here are some basic examples on how to save energy in your own simple ways at home:


Lessen the use of your heater.


Did you know that 58% of the air coming from the heater goes out through the window? A solution for this is to apply a blackout film or sheet to your glass window, or put an airtight tape around your window. There are also curtains and blinds that are made to keep the warm temperature from the heater within the room. By doing this simple step, you can shorten the time of heater usage to save energy.


Changing your light bulbs.


It has already become common knowledge that LED light bulbs save more energy than incandescent bulbs. Just by changing your light bulb, you can save up to ¥2,430 in a year. Talk about big savings.


Choose appliances with On and Off features.


Opt for appliances that have a function that you can easily turn on and off. Using timers and power strips with switch can frequently lower your energy usage.


Why is energy saving necessary?


The reason why energy saving is a must is because if you use too much electricity, you release too much energy. Releasing too much energy is directly proportional to the volume of greenhouse gases such as CO₂ that will be emitted.


As Greta Thunberg, a 16-year-old environmental activist who is attracting attention worldwide, said if we don’t stop emitting greenhouse gases, we will take away the future of the next generations to come. It can be seen that last year’s extreme heat and heavy rain have already had a serious impact on our lives. Therefore, it is necessary to make an effort to reduce greenhouse gas emissions so that the heat from the sun will not accumulate too much on the earth’s surface.


Another important note to remember is that there is more CO2 in heating compared to cooling. This cold season, there are more opportunities to use heaters. Using excessive heating doesn’t only take a toll on your wallet, but is also unfriendly when it comes to the environment. That is why we need to devise a way to improve the thermal insulation of our houses so that warm air does not escape and therefore saves energy. With Energy Saving DIY, you can improve the thermal insulation of your home with so little effort.
