Future demands of sustainable energy
Sustainable energy
Sustainable energy is a type of energy which is prerequisite that fulfill the present day demands of the energy. All renewable energy sources are included in the energy resources that are sustainable. These energies include:
• Solar energy
• Wind energy
• Tidal energy
• Geothermal energy
• Bio-fuels
• Fission energy
Bio-fuels a sustainable energy
Here we will emphasis on the bio-fuels as a source of sustainable energy. When we talk about the bio-fuels, it’s the source of energy derived from the decay of organic material and the advantage is that this material is not harmful for the environment. As we know with the passage of time the fossil fuels are declining like coal, gas and petroleum while the bio-fuels have got a very bright future and it has the ability to replace the fossil fuels and can act as a useful source of renewable energy. Bio-ethanol is the very common type of bio-fuel. Sugar cane is the source of bio-ethanol. It is produced by the process of fermentation of organic matter. At present the consumption of ethanol is approximately 10% and according to international energy agency its demand will increase up to 30% till 2025.
Currently, it seems to be very difficult for the researchers to find out the methods by which they could make it economically feasible. The aim of the researchers is to find the ways by which they could make the efficiency of bio-ethanol equivalent to the efficiency of gasoline which is derived from the fossil fuels. Well when we talk about the efficiency of any fuel it refers to the output it can give for a particular purpose.
Sustainable energy efficiency
The research has revealed that corn derived ethanol has efficiency not more then 20% but incase of gasoline the efficiency is remarkable which is around 75%. The efficiency recorded for biodiesel fuel is 69%. Due to the research, a positive side of the bio-fuels has came up which indicates that the efficiency of cellulose produced by the plants is 85%. This efficiency is more then the efficiency of nuclear energy.
Sustainable energy advancement
Stock exchange of New York reveals the information that the fluctuations in the prices of oil are directly related to the bio-fuels. Many experts claim that the prices of oil will keep rising if their source is depleting. Analysts also claim that the demand of bio-fuels can only be increased if the Government promotes the bio-fuels by giving the subsidies upon it. This is the only possible way to decrease the demand of gasoline and bring the bio-fuels in the main stream. In such a way the experts tried to relate the prices of petroleum with the bio-fuels.
Numbers of countries are taking interest in developing and promoting the bio-fuels so that it can replace the fossil fuels for the future demands of energy. Brazil is standing on number one in this race. Brazil has become the top most producer of the bio-ethanol derived from the sugar cane. The annual production of ethanol in Brazil is 3.5 billion gallons. United States is standing second in the race of ethanol producers. So we can conclude that bio-fuel is an undeniable source of sustainable energy.
