10 Super Easy Practices That Are Good for the Earth—and Your Budget

1 Walk or Bike

Cities and even many small towns are increasingly focused on becoming more walkable and bike-friendly. So why not take advantage? Obviously, neither of these modes of transportation requires the use of fossil fuels or electricity. They’re also free or nearly so. Depending on where you live, you might not even have to buy a bike: The bike share program in Washington, D.C., for instance, costs $75 per year and rides are free if they last 30 minutes or less. (Check out MONEY’s ranking of the Best Places to Walk or Bike.)

2Group Errands Together

You could take separate car trips to go grocery shopping, get the oil changed in the car, and visit the doctor for an annual checkup. Or you could combine them into one outing, in a process some call “trip chaining,” which is as simple—or challenging, for some—as being a little more organized and efficient. By planning ahead and grouping errands, you save time and gas money and reduce congestion on the roads.

3Use Public Transportation

Some parts of the country have better public transit than others, and surveys indicate that people—millennials especially—place a high priority on living in cities with good options for getting around. This makes sense for a number of reasons. According to a study on commuter satisfaction, people who get to work on foot, bike, or via train are happiest. These options are not only more affordable compared with driving, the time of one’s commute is more consistent and therefore less stressful. Check out the tools at PublicTransportation.org to scope out transit options and see how much money and carbon emissions you could save by using public transportation in your neck of the woods.

4Drink Tap Water

Americans spent roughly $13 billion on bottled water last year, up 6% from 2013. We’re drinking roughly 34 gallons of bottled water annually per capita, up from just 1.6 gallons in 1976. Granted, this is a much healthier option than sugary beverages, but is bottled water any better for us than tap water? According to the Environmental Protection Agency, tap water is completely safe; many bottled waters are just tap water that’s sometimes (but not always) filtered. And bottled water easily costs 100 times or perhaps even 1,000 times more than tap water. Only an estimated 23% of disposable plastic water bottles are recycled, by the way.

5Shop with Reusable Bags

The environmental benefits of shopping with a reusable bag like these recommended by Real Simple are pretty obvious: They eliminate the need for plastic bags that tend to wind up in landfills. Shopping with a reusable bag may also save you money, because stores in places like Dallas and Encinitas, Calif., charge customers 5¢ or 10¢ apiece for non-reusable bags.

6Don't Overdo It on Groceries

Somewhere between 25% and 40% of the food we buy in the U.S. is thrown away. What this shows is that too many of us buy too much at supermarkets and warehouse bulk-supply retailers, and/or that we’re not particularly good at strategically freezing or concocting leftover dishes. To waste less, shop smarter and be creative with foods that might otherwise be dumped in the trash. And to avoid going overboard with impulse purchases at the grocery store, always make a shopping list in advance, and stick to it.

7Heat and Cool Your Home Wisely

Among the many straightforward and fairly simple steps you can take to trim back household costs and conserve resources: Turn the heat down in winter (you’ll shave 1% off your heating bill for every 1 degree lower); use fans rather than nonstop A/C in the summer; insulate around doors and windows to protect from drafts; and put heating and cooling systems on a timer so that they’re only in use when needed.

8Use Energy-Efficient Lightbulbs, Appliances

They tend to cost more upfront than less efficient models. But they’ll save you money in the long run because they eat up less electricity when being used, and, at least in terms of lightbulbs, they have longer lifespans so therefore have to be replaced less frequently. As for appliances, look for the Energy Star label as a sign of a product’s efficiency—and its potential to shave dollars off your utility bills.

9Be Practical About Landscaping

It’s not wise to battle against Mother Nature by trying to force flowers, plants, and grasses to grow in areas where they’re simply not suited. A low-cost, low-maintenance yard is one that incorporates native plants and greenery that flourish in your zone, without requiring extensive watering, fertilizer, and attention—nor a big budget. Check out classic tips from This Old House and Better Homes & Gardens for landscaping that’s gorgeous, affordable, and earth-friendly. Don’t fixate on having a prototypical grassy front lawn, which may look good but often requires loads of time, energy, money, water, and chemicals to maintain.

10Compost

Many towns give residents free or deeply subsidized composters, and using one is generally as simple as dumping vegetable peelings, coffee grounds, fallen leaves, grass clippings, and such into the bin. The resulting material can be help your garden and new plants grow, and eliminate much of the need to water and buy fertilizers and pesticides. Composting reduces the amount of waste in landfills as well, of course. (Even apartment dwellers can get in on the act with vermicomposting, or composting with worms.)
