1.) Here's a perfect AutoblogGreen Father's Day gift. With a Waste Vegetable Oil conversion kit you can not only turn a diesel car into one that can burn straight vegetable oil, but the conversion can be a project that fathers and children can work on together. Perhaps this is an idea for you if you're a father who wants to spend more time working out in the garage with your kids. Give a gift to yourself this year. Kits are available at GreaseCar, Elsbett, and other sites.
2.) A less expensive way to get into biofuels is by taking the time to read a book on, say, biodiesel. These books offer up a new kind of beach reading, one that's concerned with keeping the beaches clean in the future.
3.) if wagering is your thing, perhaps stock in ethanol companies is the right gift.
4.) Dads who drive a lot could easily benefit from a gift subscription (or membership or whatever they're called) to a carbon offset program like TerraPass.
5.) And, of course, the greenest gift of all just might be going for a walk with your dad. Enjoy!
