Even though the RECS show a downward trend in energy consumption, the cost to heat and cool a home continues to rise across the United States. This has necessitated the need for newer homes to feature better insulation and other energy saving components, but has also led to energy efficient improvements to older homes.
Current occupants in RECS sampled homes were asked about energy-efficient improvements they had made. Over 40 million householders (35 percent) used caulking or weather-stripping to seal cracks and air leakages around their house, and 26 million (23 percent) added insulation.
It is apparent that energy efficiency remains a priority for new and existing homes and this trend is expected to rise as the cost to heat and cool continues on an upward swing.
