Today's post will give you ten easy ideas on how to use water more efficiently in your kitchen and home. Water is one of cooking's most important ingredients, yet the wide availability of safe drinking water throughout the developed world can make it easy to take this precious resource for granted. It's not surprising, then, that water is one of our biggest sources of preventable waste.
By rethinking your water use, you can help the environment and save money too.
Optimizing Tap Water and Hot Water Use:
1) By installing a simple aerator onto your faucets you can reduce your tap water use by as much as 50% with little sacrifice in functionality.
2) When you let your hot water faucet run until the water heats up, don't let that excess water go to waste. Consider capturing it for other uses, like watering your plants or for cleaning.
3) Briefly turning on the hot water tap is a no-no. If you turn on the hot water and let it run for a few seconds, you are still wasting hot water--even if no hot water comes out of the tap. For every drop of cool water that runs out of the faucet, an equal amount of hot water flows from your heating tank into the pipes. That hot water never makes it to the tap: it just sits in the pipe, cooling its heels, while your hot water tank draws in new cold water to heat up again! It's a double whammy of energy waste.
4) Bonus tip for kitchen sinks with single, uni-directional faucets: if you intend to draw cold water from your faucet, take care to push the faucet handle all the way over to the "cold" side. If you push the handle straight back, you'll pull a mix of hot and cold water, wasting heat and energy for no reason.
5) Using your dishwasher doesn't just save time, it saves water too: hand-washing dishes in the sink can use twice the water of an average dishwasher--as long as you make sure to run it with a full load.
6) Most homes are fitted with conventional tank-style hot water heaters that use energy to keep a large reservoir of water heated at all times. If you use hot water infrequently and in small quantities, consider installing an on-demand hot water heater instead.
Saving Energy While Cooking With Water:
7) You can heat a pot of water more efficiently by covering it with a lid, trapping heat and steam that would otherwise escape.
8) An Electric Tea Kettle (two typical examples on Amazon) is by far the most efficient household tool for boiling water. These handy gadgets boil water much faster and with far less energy than a traditional stovetop tea kettle. Also, once the water comes to a boil, most electric kettles automatically shut off, reducing energy waste further.
9) Water is exactly the same temperature at a vigorous boil as it is at a gentle boil, and no matter how much additional heat or energy you apply to boiling water, the temperature will never exceed 100 degrees Celsius. Once your food begins boiling, consider turning the burner down significantly. You can maintain a slow or moderate boil with considerably less energy.
10) Furthermore, you can turn the burner off entirely during the last few minutes of boiling pasta or vegetables, using the water's passive heat to finish cooking your food. Water holds heat extremely efficiently, so this technique can save a lot of energy without compromising food quality.
A final note of thanks: I owe an enormous debt of gratitude to Kate Heyhoe and her exceptional book Cooking Green for inspiring me to write this post.
Without changing your politics, or completely disrupting your routine, you can reduce greenhouse gases simply by rethinking what you do every day: consume food.
