"Will biofuel usage require land? Absolutely, but we think the ability to use winter cover crops, degraded land, as well as using sources such as organic waste, sewage, and forest waste means that actual land usage will be limited. Just these sources can replace most of our imported oil by 2030 without touching new land."

We've got to control our own energy. Now, not only oil and natural gas, which we've been investing in; but also, we've got to make sure we're building the energy source of the future, not just thinking about next year, but ten years from now, 20 years from now. That's why we've invested in solar and wind and biofuels, energy efficient cars.
