1. Make Mondays Meatless
You may have heard of the Meatless Monday phenomenon that's taken over celebrity-chef kitchens and school lunchrooms alike. The point isn't to convert the world to vegetarianism, but to show people that going without meat one day a week isn't that hard and can encourage you to try foods you might otherwise pass up in favor of a burger or steak. We even found The 4 Best Meat-Free Replacements For The Grill. If everyone in the U.S. refrained from eating meat once per week—it would be the environmental equivalent of not driving 91 billion miles. Take it a step further and try eating vegan once per week–if every family in the U.S. vetoed meat and cheese just one day a week, it would create the environmental benefits of taking the family car off of the road for five full weeks or shortening everyone's daily shower by three minutes.
2. Save Up For A Good Slow Cooker
Your kitchen accounts for one-third of your home's energy use and much of that comes from cooking. Though it seems counterintuitive, a slow cooker is the most energy-efficient vessel for cooking dinner because it heats a small pot filled with food—not all of the air around your food the way that an oven does. Plus, they're great for one-pot meals—less energy used and less cleanup for you. If you're cooking a meal for seven hours in a slow cooker—it'll cost you less than half of the amount of energy it would take to cook the same meal in an oven for an hour.
If you are in the market for a new oven, consider a convection oven. According to the Consumer Energy Center, these ovens are more efficient in distributing heat—reducing energy use by about ⅓ of what standard electric or gas ovens use.

3. Invest In Good Eggs
Pastured eggs provide triple the benefit to people as well as the planet. Eggs are among the most ecofriendly animal protein sources on the planet–creating about 6 times less greenhouse-gas pollution than beef. According to Penn State University research and other studies—eggs from hens raised on grass pastures contain twice as much vitamin E, nearly 3 times more omega-3 fatty acids, one-third less cholesterol, one-quarter less saturated fat, and two-thirds more vitamin A than standard supermarket eggs that come from tightly confined caged hens. Pastured eggs are also one of the 11 Instant Mood-Boosting Foods.
If you can't find organic pastured eggs from a local farmer, look for organic, Animal Welfare Approved, or Certified Humane eggs at your grocery store. According to Environmental Working Group, Earth-friendly animal protein sources also include organic yogurt and organic 2 percent milk.
4. Upgrade Your Cookware
Pans with warped, wobbly bottoms can waste just as much energy as an old, outdated refrigerator. Why? When your pots don't come into contact with the burner on your stove, most of the energy from the burner gets wasted. Buy new cookware made from either clad stainless steel–these pans have three layers of metal on the bottom—or cast iron–both of which are less prone to warping. Cast iron is a great heat conductor, as well, which means you can shut off the burner or stove a few minutes before your food is finished cooking and let the pot do the rest. Finally, match your pots and pans to the right burner size—using a six-inch pan on an 8-inch burner wastes 40 percent of the burner's energy.

5. Eat Raw Once Per Week
To vitalize your health and eliminate the need for stovetop or oven energy, eat raw food at least one day a week. Since most of our electricity comes from burning coal—and natural gas is now tapped through risky, unconventional hydraulic fracturing—you're doing a service to the earth by going raw once a week. Plus, raw food is bursting with vital minerals and nutrients. For something different, try fermenting food—the end result is loaded with immune-system-boosting probiotics.
6. Waste Not, Want Not
Food waste in the U.S. has reached staggering proportions–with over 1,400 calories of food wasted per person per day. It takes a lot of oil—185 million barrels each year—to grow all that food. That's 46 times the amount that gushed out of the Deepwater Horizon during the 2010 oil spill. One of the 11 Ways To Cut Food Waste In The Kitchen is to focus on the fridge—reorganize it so that leftovers and perishable goods are in plain sight and retrain your nose so you can tell if something smells safe or rancid.
7. Love Your Lentils
Lentils are the most climate-friendly form of protein on the planet. To make sure that your body is primed for maximum protein absorption when eating one of the world's healthiest foods, pair a lentil-based meal with a whole grain like brown rice. A cup of cooked lentils offers a whopping 18 grams of protein, about one-third of what you need in a day.
8. Look For Green Meat
When you do opt for meat look for greener meats from animals raised on grass. Ask a farmer how his animals were raised or look for reliable certifications such as Certified Organic, Certified Humane, or Animal Welfare Approved. And choose from the 10 Healthiest Fish On The Planet—which are ocean-friendly, omega-3-rich fish. All consume less energy to produce and emit fewer greenhouse-gas emissions than their factory-farmed counterparts.
9. Eat Dinner As A Group
Aside from the obvious emotional benefits of eating a dinner with loved ones, family dinners breed more emotionally stable teenagers and children who maintain a healthier weight—according to published research—and they save the planet. Eating as a group means you're only cooking once—using less energy than if everyone in your home cooks an individual meal.

10. Eat Organic
Some of the biggest energy hogs in agriculture are avoided in organic farming systems—where energy-intensive chemical pesticides and fossil-fuel-based fertilizers are banned. In fact, organic farming uses 45 percent less energy and creates 40 percent fewer greenhouse-gas emissions than conventional framing—according to data from the Rodale Institute's 30-year farming-system trials. Organic farming is much healthier for people, too. The most commonly used pesticides—glyphosate and atrazine—have been shown to damage DNA and lower child IQ and in animal studies are linked to infertility, low sperm count, and prostate and testicular cancer.
