Energy defined by Einstein as E=MC2, is not that simple as it seems. It is not ‘just’ a product of mass and square of velocity, but, it is the basis of everything. It is everything. We talk, we run, we play, we eat, all of the tasks require energy. It is a presence which can neither be created nor destroyed.
This is Newton’s third law which gives the basis of energy transfer. In the real world, we use energy from the coal and petroleum that are the non-renewable sources of energy. These conventional sources are exhaustible and more polluting.
So, the shift in attention goes to the renewable sources of energy which are new and more technologically advanced. If we specifically consider fuels which are used in our economy, those include fuels for generators, automobiles and the airplanes. The demand of fuels to meet the needs of these sectors is too great and if we replace the fuel used with a renewable, cleaner and greener fuel, then it would solve a lot of problems like a decrease in pollution and less dependency on the conventional sources.
But what are these alternative fuels which are supposedly so good? This is explained in the next few bullets.
- The alternative fuel is a very sought-after topic for research among engineers as well as biologists.
- The fuels have various generations, each of them pointing towards the level of advancement of the fuel.
- The first generation of biofuel points towards the usage of edible crops to produce fuel. But, it creates the problem of competition between food and fuel.
- So, the second generation of biofuels takes into consideration this problem and uses the inedible crops for the production of biofuels. The major problem of these fuels was very high velocity etc which can be overcomed by blending.
- The third generation is an advanced stage of biofuels which focuses on the production of biofuel through genetically modifying algae.
This is the basic crust of the new and renewable sources of energy which are being considered for the fuel industry.
