Advanced energy harvesting from solar using Photovoltaics
While i'm browsing about saving electricity last night, i accidentally seen a web page which says that "inorganic fuels are going to dominate the future". Suddenly an article i read about Organic fuels struck my mind and i recalled some informations from that article and i posted some of which i recalled.
       Sustainable, green, renewable, organic- the words are remembered so often while debating about energy and climate changes that they tend to sound as they were similar.But of course they don't."Nuclear reactors emit no carbon and are therefore in a sense green, but uranium is non-renewable"-this is what i read in that article but this can't be green in any sense as because they don't emit carbon. First of all we are using the word "GREEN" not only to represent energy sources that will never emit carbon into atmosphere, instead we are using this word to represent the energy sources which are not giving away any by-products that are harmful to environment.

Implementation of solar cells in a large scale
     Hydro power is green and renewable but may not always be sustainable; coal is inorganic but it's carbon emissions make it the very opposite of green.All that is obvious enough. But even so, it may be jarring to hear- as we have found and will describe that- organic biofuels can't possibly fuel a growing world economy in a sustainable manner, whereas, in principle, inorganic fuels could.
     Now we are entered into a biofuel boosted world and most of them were saying that biofuel is the future and already america started producing it in a huge quantity. Both the biofuel and carbon scenarios are carbon neutral by definition- solar for obvious reasons, biomass because carbon emitted is reabsorbed when plants regrow(biofuels are carbon free only if crops are planted on existing tilled fields).
     Biofuels provide around 6.5 megawatt hours per square kilometer, That's roughly enough to power 60 homes.The photovoltaic system covering the same square kilometer, with a typical commercially available system efficiency of 15.5%, could power up to 12,000 homes. Also, in cars which are powered by the internal combustion engines are replaced with electric vehicles that are three times as efficient-a direct result of losses in the thermal cycle of the combustion engine.
     There exists a lengthy list which describes the advantages of inorganic over organic and i don't have much time to post them all. Instead, I can say that "Forget biofuels- only inorganic energy sources can provide prosperity   for all and forever".
