Do you want to use an economical and environmentally friendly biofuel? Just grow grass. Burning grass pellets will produce an energy-efficient biofuel, according to Jerry Cherney, a professor of agriculture at Cornell University. In this news release, ‘Grass as Fuel,’ he says ‘Burning grass pellets makes sense; after all, it takes 70 days to grow a crop of grass for pellets, but it takes 70 million years to make fossil fuels.’ Unfortunately, there is anything like a grass political lobby in Washington, so he might not be heard. But with current oil prices, more and more people will be tempted to use cheaper — and cleaner — sources of energy.
