Alternative fuels, also known as non- renewable sources, are substances that can be used as fuels, other than conventional fuels. Conventional fuels include: fossil fuels (petroleum (oil), coal, propane, and natural gas), and nuclear materials such as uranium.
[ 1] The fuels we use now are finite, meaning they have a limited life expectancy. This along with the toxic waste they produce has made environmentalist and government officials alike take precautionary steps so that we do not become flummoxed at our future once they expire.These alternative fuels, or other wise eferred to as green fuels are the main focus to the future replacement of the ever reliant upon fossil fuels. These alternative fuels include; biodiesel, hydro electric power (otherwise abbreviated HEP), geothermal energy/heat, solar energy and nuclear energy.
Consequently they all have their downfalls which hinder any useful production they may possess.Alternative fuels have many advantages some include; their ability to be burnt easily without producing harmful greenhouse gases and most importantly cease our huge dependence on fossil fuels. Nonetheless at the same time they do also ave some disadvantages; maize, a grass indigenous to the Mexicans which is used as food also serves as a biofuel, this causes many issues ethically as the working class find this as their main source of food.The use of maize as a biofuel has indirectly raised its price, and in this economical climate it is becoming more and more out of their reach to feed themselves. Other disadvantages include their environmental damage, in HEP the environment of certain wildlife is ruined therefore causing environmental damage at the cost of the sustainability of our fuels and lives. Nuclear power can be very destructive; the splitting of a radioactive atom produces great amounts of energy which we can harbor for our use.However there are waste products involved to which if mishandled can lead to apocalyptic destruction, as was discovered in the aftermath of the Chernobyl incident.
Cost effectiveness: some alternative fuels are very costly in setting them up such as nuclear power stations. These become very problematic politically when LEDCs (less economically developed countries) are not allowed burn the easily accessible and cheap ossil fuels available to them, and at the same time do not have the financial muscle to build their own power stations.The newly produced hybrid vehicles to replace the existent fossil burning cars are priced highly for most of the 30 million drivers in the United Kingdom.
We can personally reduce our carbon footprints by taking some simple but practical steps; these incorporate; replacing your light bulbs with energy-saving fluorescent light bulbs that will easily last a couple of years. You could take a shower than a bath and insulate your loft to avoid heat loss from above.
