Power generation ’ sustainable or not?

One of the most threatening problems in the world at present is the depletion of fossil fuels. The world is facing an acute shortage of fuel sources. Some break-through has been achieved in the form of solar energy, hydrogen fuel cells, biofuels etc. The use of these alternatives decreases the dependency on the present fossil fuels and also reduces the pollution to a great extent. In this paper, the author's idea on chemical and biological processes to produce alternate fuels has been discussed. Moreover this fuel source can also be used to generate electricity to run household appliances.The other way of producing hydrogen is the use of Green Algae.The other alternate fuel source is biofuels. This is produced by the processing of any plant part of biofuel plant sources. The concept is to identify and isolate the gene responsible for the synthesis of triglycerides (hydrocarbons) in these plants, and transform it into commonly found plants, which have a short growth period and which could withstand the effects of the gene. The prime criterion, as a whole, is the quest for the most optimum renewable source to keep the world moving on its wheels, not only for now, but also for the future generations.
