Over at AutoblogGreen, there's a nice two-part summation of the good, the bad and the ugly when it comes to alternative fuels (Part 1, Part 2). Aside from simply defining how CNG (Compressed Natural Gas), E85 (85% ethanol), biodiesel, SVO (Straight Vegetable Oil) and Electricity work, there's also a pretty good analysis of pros & cons, as well as real-world issues like cost, availability and long-term sustainability. After the rundown of what's what, what goes where, they ultimately pick the winner. Which is it? We won't ruin the surprise, but here's a hint: the fuel at the top of the heap isn't a liquid. Be confused no more, and read it here. [AutoblogGreen]
