Alternatives To Fossil Fuels Essay

1113 words - 4 pages

Fossil fuels which are hydrocarbons found within the top layer of the crust, are natural resources formed by the decomposition of anaerobic buried dead organisms such as dead plants and animals. They fossilize through the exposure of heat and pressure in the Earth’s crust. Fossil fuels are non-renewable resources because of the millions of years they take to be formed; prime examples are coal, natural gas and oil. When coal, natural gas and oil are burnt they release gases into the atmosphere such as carbon dioxide also known as CO2 which is a greenhouse gas that traps heat from the lowest part of the earth’s atmosphere, which also contributes to global warming. There is also Sulfur dioxide (SO2) which is a key contribution to acid rain, Nitrogen oxide (NO) which also contributes to acid rain and smog, as well as health issues. Reserves of fossil fuels are being depleted much faster than new ones are being formed.
Our world relies on fossil fuels because they are very essential for the operation of our day to day lives and are thought to be beneficial and make our lives easier. Without them we wouldn’t be able to do simple things like; run our cars, heat our homes or have electricity. There are positive aspects results from fossil fuels; however at the same time there are sever negative impacts on the environment because of the inefficiency and environmentally damaging characteristic of these fossil fuels. The product produced by these fossil fuels is largely the blame for the green house effect. Fossil fuels have a significant effect on the global environment, they cause harm through biomass which is its recovery, transpiration, refining storage and combustion phase. When fossil fuels are recovered, for example oil, the top soil of the earth is destroyed during the transpiration period. You run the risk of an oil spill which can virtually destroy certain animal habitats, during petroleum reining there is air and water pollution; which by storing fossil fuels you run a risk of leaks and contamination of drinking water. And on top of that during the burning of the fuels there is a release of greenhouse gas, increasing global warming.
Global warming is the warming near the earth's surface that is a result when the earth's atmosphere traps the heat of the sun. The earth’s temperature is increasing but the changes are small, so far, but they are expected to increase and the process to speed up, within the next fifty to one hundred years. The earth may be hotter than it has been in the past million years, as oceans warm and glaciers melt, land and cities along coasts may be flooded. Heat and drought may cause forests to die and food crops to fail. Global warming will affect weather everywhere, plants and animals everywhere, people everywhere; humans are warming the earth's atmosphere by burning fuels, cutting down forest, and by taking part in other activities that release certain heat trapping gases into the air. Of course one major cause of...

Is Biodiesel a Viable Alternative To Diesel From Fossil Fuels For Trucks And Buses?

1029 words - 4 pages of sulfur compounds and aromatics (Habmigren, 2003). Until today, it is still the only alternative fuel for motor vehicle. The biodiesel blends have ranged from 2/98% (B2), 20/80% (B20), to 100% (B100) (Hafman, 2003). The reasons biodiesel is a viable alternative to diesel from fossil fuels for trucks and buses are it can reduce the pollution, it can enhance the country's economy, and it is renewable sources and can produce almost same energy as

As the situation gets increasingly worse, a large majority of the ice caps have melted away and has caused the ocean levels to rise. CONCLUSION: Ever since the Industrial Revolution, fossil fuels have become the world’s primary source of power, but this may propose a problem in the near future. The fossil fuels were used as alternatives for charcoal and wood to power trains and boats. Soon

Fossil Fuels vs. Renewable Energy
