With the mainstream media waking up to the fact that oil supplies are dwindling and, despite some attempts at conservation, global usage continues to grow, there is more serious thought and action on the alternative fuel front. Most informed opinion agrees that it is much too little much too late. Still, hopes springs eternal and it is always good to see some success, especially when it involves a renewable resource and doesn't add to overall CO2. England recently announced some action in this regard: a grass-burning power station. I do wonder though the degree to which such repeated grass-harvesting is depleting to the soil and what the cost may be of fertilizer - which, if synthetic, would probably be petroleum-derived, a further detraction.
