What do you mean, you’re not green? Being green is the new anti-drug! Do you hate the environment? You’re lucky Al Gore doesn’t kick you in the shins!

Even though scientists say we have roughly a decade to effectively deal with global warming, it’s still not too late to check out Elizabeth Rogers’ and Thomas Kostigen’s newest, The Green Book. The authors stopped by The Today Show to demonstrate a few of the dozens of simple things American’s can do to cut down on its massively disproportionate energy consumption.

For instance, cook your food with a microwave, which is roughly four times more efficient than a traditional electric oven. If every American used a microwave for every meal, the authors point out that we would save as much energy as the entire continent of Africa consumes in one year.
