One of the greatest problems in recent years in America is the dilemma of alternative forms of energy. While all forms of energy have various pros and cons, some are much more favorable than other depending on renewability, reliability and cost. Some are extremely energy renewable, some are much cheaper than others, some are much more reliable and some take up a lot less space than others. There has been a lot of disagreements as to what the best source is, pro's and con's considered. All of the sources have one thing in common: they all have a major reason that could triumph over their alternatives. Amid all the argument is an energy source that can tops them all, but it may be a while before it's accepted as that. Our modern society is to a large extent based on using fossil fuels. Still, due to overpopulation, climate change, and the scarcity of resources, one of the most precious and efficient sources of energy, oil, have already began to exhaust. This fact has caused scientists globally to seek for substitutes to fossil fuels to avoid economic and industrial collapse. Experts in the field of sustainable energy have turned their attention increasingly towards a renewable yet reliable energy as a viable alternative to fossil fuels.
We can say that there are three types of fossil fuels that are most widely used for different purposes, including coal, oil or petroleum and natural gas. Coal is one such source of energy, which has been in use for centuries and is abundantly found on the earth. Presently, coal is used in industries for the production of iron, steel, cement, paper, etc. It is also used in power plants for generating electricity.
Oil comes second in terms of popularity. Crude oil undergoes some processing before its usable form can be obtained. It is then used as fuel in vehicles, aircraft, ships and several machines. The energy sources that produce the most energy quickest are Coal and Nuclear. Both produce energy much faster than any other energy source. The major downside to these types of sources is the sheer amount of pollution they produce, and the effect they have on the environment. Also, neither source will last indefinitely. Coal will eventually run out, and nuclear power plants slowly wear themselves out over time. However, there is enough coal to last for hundreds of thousands of years, and Nuclear power plants can be renovated and fixed as they digress.
When fossil fuels are burned, a large amount of carbon dioxide is released, which leads to greenhouse gases. In the atmosphere, it absorbs heat and contributes towards the green house effect. This is known as global warming and it has numerous harsh effects on our environment. Another toxic gas released by fossil fuels is sulfur dioxide, which reacts with the moisture present in air to produce sulfuric acid. “…This leads to acid rain, which causes extensive damage to the living as well as nonliving matter on the earth.” Exclaims Eftihia Tzen. Oil is often transported...
