Geothermal, or "geoexchange," systems work on the simple principle of regulating indoor heating or cooling by using the consistently moderate temperatures just below the earth's surface. Geothermal heat pumps take advantage of this by moving heat through water in underground pipes to make it either warmer or cooler inside the home.

The United States Department of Energy says that household heating and cooling accounts for around 54 percent of the average American's utility bill. Although some savings can be achieved through proper equipment maintenance and upgrades, an energy-efficient furnace alone will not have as great an impact on energy bills as using a whole-house approach.
Want to attract pollinators — bees, butterflies, hummingbirds, bats and beetles — to your garden this spring? Select flowering plants that bloom at different times to provide nectar sources throughout the growing season. Place plants in clumps to supply large areas of color and coverage that attracts pollinators.
