Short Essay On Non Renewable Energy

‘Did you know that, if taken advantage of to its fullest extent, sunlight that beams on the earth for one hour could meet world energy demands for an entire year?’ This demonstrates that there is enough energy potential to meet the ‘world energy demand’.

But, what is energy and how does it concern us? Energy is an essential factor of life which humans heavily depend on. In Physics, the definition of energy is the resources needed to do work. Biologically, energy is used through respiration to allow the human body to function. However, most of the energy that we depend on so heavily, in the modern world, is used to make electricity.

There are many ways in which energy can be converted to electrical energy. However, the resources can generally

This reliance on finite resources has led to much research into other ways of producing more sustainable energy. But why should we change if the resources have not run out yet? The problem is that non-renewable energy resources emit many harmful gases into the environment. They not only pollute the atmosphere, but also cause many diseases and health issues globally. In addition, the total amount of energy extracted from energy resources make them extremely inefficient. The electricity output of a coal power station, for example, is 35% of total potential energy, whilst the remainder goes up the chimney, so to

Many countries have kick-started their economies due to the discovery of oil. Oil, gas and coal reserves can also benefit the future generations if channelled in the correct way. The space needed for the power stations is far less than that needed for renewable energy. In addition, Nuclear energy is so powerful that a power station is only filled up once in every 25 to 30 years. Lastly, non-renewable resources are much cheaper because of the abundance of power received when a small amount of resource is used, and therefore more affordable to the poor. Surely all these benefits outweigh the
