Energy is defined as the capacity of a physical system to perform work. In other words, It can be explained as the ability to perform or complete any type of work whether it is physical or mental activity.
We utilize energy in different forms in our daily routine life and cannot think even about to survive without it. We use energy to light our homes and for street lighting as well, to be able to power machineries and equipments in factories, helps to cook our food, for playing music and operating televisions and many more every day regular uses.
Energy conservation is the decision and practice of using less energy. Turning off the light when you leave the room, unplugging appliances when they're not in use and walking instead of driving are all examples of energy conservation.
Energy conservation plays a significant role of lessening climate change. It helps the replacement of non-renewable resources with renewable energy. Energy conservation is often the most inexpensive solution to energy shortages, and it is more environmentally kind alternative to increased energy production.
Since, we have limited quantity of non-renewable energy resources available on earth, it is very important to preserve energy from our current supply or to utilize renewable resources so that it is also available to our future generations.
Energy conservation plays a very important role because utilization of non-renewable resources also impacts our environment. Specially, usage of fossil fuels supplies to air and water pollution such as carbon dioxide is produced when oil, coal and gas combust in power stations, heating systems, and engines of car.
As we all aware of that carbon dioxide works as a transparent layer in the atmosphere that is part of the cause to the global warming of the earth, or we can also name it as greenhouse effect. Global warming has its own consequences in our atmosphere. It has its deadly effects like spreading of different diseases, warmer waters and more chances of hurricanes, financial costs, polar ice melting, increased chances and intensity of heat waves. Ozone depletion is the reduction of the protection layer of ozone in the uppermost atmosphere by chemical pollution. Ozone layer is the protection line between earth and the ultraviolet rays emitted by the sun. People who have more exposure to UV radiation can have some health problems like DNA damage, skin cancer, aging and other problems related to skin.
There could be some possible issues that include a danger to human body health, impact on environment like rising sea levels, and major changes in vegetation growth methods. When coal is burned, it realises sulphur dioxide into the air and therefore, it reacts with water and oxygen in the clouds and forms acid rain. Acid rain kills fish and trees and also damage limestone buildings and statutes. These types of global problems can be resolved. As per the data of United States calculated per year, we found that the average family’s energy uses produces over 11,200 pounds of air pollutants. Therefore, every unit of kilowatt of electricity preserved diminishes the natural environment impact of energy use
