The topic that selected is energy conservation because it is a big environmental problem that we need to work on to save the environment. This problem is very serious when energy is an expensive source and a very useful one. This problem causes environmental pollution and it needs to be reduced in order to make the earth a safer and healthier place. We all need to do our part to address this problem before it becomes worse.
Energy conservation refers to efforts made to reduce energy consumption in order to preserve resources for the future and reduce environmental pollution. Energy efficiency is known as “the fifth fuel” and it can help the demand for energy just as coal, gas, oil or uranium can. The burning of fossil fuels releases greenhouse gases, which contribute to global warming and nuclear plants generate life-threatening waste. The standard economic theory suggests that technological improvements increase energy efficiency, rather than reducing energy use. This is called the Jevons Paradox and it can occur two ways. Increased energy efficiency makes the use of energy relatively cheaper, thus encouraging increased use. Increased energy efficiency leads to increased economic growth, which pulls up energy use in the whole economy. Electric motors consume more than 60% of all electrical energy generated and are responsible for the loss of 10 to 20% of all electricity converted into mechanical energy. It has also been shown that natural day lighting increases productivity levels of workers, while reducing energy consumption.
There are living and non-living factors that contribute to the problem of energy conservation. For example, a human, animal, or plant is a living factor and rock, cloud, or ocean is a non-living factor. The characteristics for living things are metabolism, growth, responsiveness to stimuli, self-maintenance, and
