Saving energy is very important, especially when the current sources of power is depleting at an alarming rate. In particular, they are oil and natural resources which are non-renewable resources. These natural resources are still the main power source for the majority of the world, so everyone, by saving energy, is helping to extend the amount of time for scientists to find and utilize other energy sources, most likely renewable ones. Not only does saving energy helps the world as a whole, but this act will also help us normal people to save money. Just leave the lights and your air conditioner on everyday for a week, you will immediately notice the effect it has on you and your family. The electricity bill will skyrocket and will leave everyone in awe. So saving energy is both beneficial to yourself and the world.
The energy generated from natural sources such as the sun, wind, rain, and tides is called renewable energy. They are plentiful and can be generated again and again. They also have low carbon emissions so they are considered green and environment-friendly. Moreover, using renewable energy can reduce your electricity bills. Unfortunately, solar energy can be only used during the daytime but not during the night or the rainy season. Geothermal energy also can bring toxic chemicals beneath the earth’s surface to the top and can create environmental changes. Non – renewable energy is the energy taken from other sources that are available on earth. They are limited and will run out in the future. They can’t be regenerated in a short time. Fossil fuels – natural gas, oil, and coal – are some examples of them. They are cheap and easy to use. However, when burnt, they release toxic gases into the air so they cause serious environmental changes such as global warming. And the important thing is that non -renewable sources will expire someday.
