Biofuels are liquid energy Version 2.0. Unlike their fossil fuel counterparts — the cadaverous remains of plants that died hundreds of millions of years ago — biofuels come from vegetation grown in the here and now. So they should offer a carbon-neutral energy source: Plants that become biofuels ideally consume more carbon dioxide during photosynthesis than they emit when processed and burned for power. Biofuels make fossil fuels seem so last century, so quaintly carboniferous. And these new liquid fuels promise more than just carbon correctness. They offer a renewable, home-grown ene... (p. 24)
