Going green or brown

US president Barack Obama's energy plan to greater use of ethanol, aiming to cut dependence on oil might worsen the situation. For production of ethanol millions of tonnes of crops like maize, sugarcane is needed, which if, the plan really takes off, it is likely that a huge chunks of farmers might switch to production of these crops which, eventually would led to increase in global food prices( because the production of other varieties of crops will decrease, which will increase demand and ultimately push the prices up) and India's situation wouldn't be better off either. Where growing sugarcane is water intensive and increased production of the crops is going to deplete the water level, which is already dangerously low. Add to this large scale diversion of land which could affects others production, of course deforestation. It could pump far more CO2 into the atmosphere than they possibly save as replacement for fossils fuel. But the success story of Brazil which practice the concept has reduced the country dependency on oils and cleaned up the transport industry to a great extent.One innovation could offers a solution, that could significantly cut down the world dependence on oil and save the planet, that is Electric car and the other option being Hydrogen car
