- 7. Pros Cons Widely Available - Used in cars, converted Non-Renewable – will eventually run out into electricity, plastics, wax, asphalt Creates a lot of jobs for the local Creates greenhouse effect by releasing community as well as globally carbon dioxide and other toxic products Safe – because it ignites at a relatively high Oil leaks will result in environmental temperature disaster by killing wild life Extremely powerful – No other fuel can Takes a lot of energy to refine: move vehicles with greater speed at longer – simple refining uses up water in large distances than oil amounts in distillation - for more difficult processes like from tar sands, the waste of water increases enormously Easier to extract and transport because it is Tankers and pipelines are vulnerable to in a liquid form terrorists and other criminals, or simple accidents Economical - Very large amounts of The price of oil keeps getting higher and electricity can be generated in one place higher because it is depleting Consistent – can run day and night, The insecurity of oil in the global financial providing constant source of power market will cause problems for countries that rely on oil
- 9. Pros Cons Renewable - the supply of biofuels Require cultivating more land than is less likely to run out is currently farmed Eco-friendly - environmentally Require modifications to vehicle much cleaner than fossil fuels, engines producing less air pollution and consuming materials Cheaper than oil - the price of oil Not widely available keeps rising Flexible – can be easily mixed with Potentially high emitters of other fuels nitrogen oxides can use waste for feedstock Is a contributor of formaldehyde to urban air Better for car engines - improve Biodiesel still requires the use of performances fossil fuels
- 12. Oil has been a combustion source for vehicles for a century, because no other fuels can move vehicles with such great speed or at such long distance. People have discovered many other renewable and eco-friendly energies that can replace oil, such as solar energy, wind power, and biofuels. However, those alternatives are not yet in practical. People are focusing on developing eco-friendly energy, rather than developing a powerful energy source. Being environmentally friendly is an important aspect that a new power generation should have. However, developing a constant and powerful combustion fuel is more important than developing a green energy. The power generation has to be practical, like fossil fuels. That is why people keep using fossil fuels although they cause a massive pollution.
