Naturally, it makes sense to fill your automatic dishwasher to full capacity before running a load. But did you know that many modern energy-efficient machines also have something called a "delay" feature? You can use this feature to run the dishwasher in the middle of the night, when energy is cheapest (because it's during off-peak hours). It reduces the energy grid load and you save money, all while waking up to freshly cleaned dishes.

When something expensive breaks, it's easy to toss it out and get something new. But in these greener times, the worlds of both ecology and technology are coming together to make repairing items easier, economical and ecological. Download apps like TaskRabbit to see if you can find someone to help you repair items like broken washing machines, dishwashers and other appliances. You might find a local repairman who is willing to offer his services at a steep discount and fix your appliances for you. If you must replace, find a place to recycle your old item.

Did you know you can cook a pot of pasta without even having the stove on the whole time? Try this energy-saving and foolproof cooking tip: Bring a pot of water to a boil and add the pasta; cook at a simmer for five minutes, then turn off the stove; cover and let the pasta sit in the hot water for an additional five minutes. Check the pasta: It should be perfectly cooked al dente and ready for your homemade organic pasta sauce. And remember, if you didn't salt the water, the cooled starchy water can be used to water plants outdoors.
