As climate change threatens to make both energy and water resources increasingly scarce, it’s important to find ways to reduce water usage and thus reduce our energy needs — making the drop to watt connection. According to research, over 12 percent of all US energy consumption is directly related to water use. There are dozens of easy green ways to commit to reducing both energy and water in your yard and garden.
Committing to a greener land-scaping plan is one of the ways we can make a big difference in our water-energy use. An average lawn uses 10,000 gallons of water a year (not including rainfall). Taking steps to redesign your yard to include more native, drought-resistant plants, instead of (or in addition to) grass, is a wonderful way to reduce your water usage and keep your landscape beautiful. Native plants adapted to your region’s climate and soil require much less upkeep, are resistant to pests and diseases, and can help with erosion. Building a yard of native plants can help reduce pesticides and fertilizers, leading to a healthier ecosystem for other plants and animals too.
Not ready to redesign the landscape just yet? There are still plenty of ways you can ensure your garden makes the most of its water. When possible, nuture old growth. Maintain those plants and trees already rooted in your yard to reduce the resources, nutrients, and water to needed to establish new vegetation. When choosing new items, focus on trees and shrubs when possible. Bigger plants can absorb more rainfall, reduce runoff, and absorb larger amounts of carbon dioxide (bonus: your trees can discourage your nosy neighbors from peeking in). Reduce runoff and erosion by adding compost and mulch to your soil. Compost will enrich your soil for healthier, happier plants, and work as a carbon sink for your yard.
Changing up your watering techniques can be instrumental in saving water too. When possible, it’s better to do the work of watering yourself. It’s much more efficient to manually water your plants with a garden hose or watering can; take a happy, meditative gardening break to give your little greens some water. The EPA estimates that you generally use 33% less water doing it yourself, rather than through an irrigation system. If manual watering is too impractical for your schedule and you have the spare funds, use an automatic irrigation system, specifically a drip irrigation or a water-efficient spray head, which are the most effective in getting water straight to the roots. The final tip: hopefully you’re an early bird, because the best time to water your plants is in the morning. It’s the coolest time of day, best for optimal absorption and decreased evaporation. Be mindful of the changing seasons, changing your watering routine as rainfall, heat and humidity change throughout the year.
