The renewable energy sector of the HVAC marketplace continues to make strides in acceptance and understanding from consumers, and the proof is in the numbers.
Per WaterFurnace Intl. Inc., more than 1 million geothermal (or ground-source) heat pumps are used in U.S. residential, commercial, and government buildings. And, that number is growing as U.S. homeowners install approximately 50,000 more geothermal heat pumps annually. Similarly, both wind and solar installations have risen steadily over the last decade, with solar accounting for 32 percent of the nation’s new generating capacity in 2014, besting the efforts of both wind energy and coal for the second consecutive year, per Scientific American.
