- Concerning biofuels, these myths include: Large-scale biofuel production is sustainable; biofuels are environmentally friendly and reduce CO2 emissions, for several countries (such as USA) biofuels will help achieve more energy independence; biofuels will help the farmers and could let them continue the current way of life, Unfortunately biofuel has some disadvantages such as we must use the corn for biofuel (ethanol) , then demand for corn goes up, production of other crops will decline , for years, including wheat, rice and others. Biofuels do not have the energy density of oil. The four best (kg/hectare) biodiesel crops only grow in the tropics. If the entire world's vegetable oil were converted to biodiesel, it would provide about 8% of world consumption of diesel. But the corn is also the major feed/ingredient for chickens, pigs, cattle; milk, cheese, eggs, hamburger, Coke, Pepsi, Jack Daniels the price of corn and other products will be grow up fast . This is worse impact. -Nuclear energy hydro production: This is also important energy source (Fig.3). Some rich countries have been choosing this kind of energy, but this could causes many dangerous problems such as not safely, hardly treat the radioactive waste, we will not be able to prevent nuclear proliferation, even the crazy terrorists could destroy nuclear plant.
