Affordable, reliable, and sustainable energy is essential to health, safety, and well-being. When home energy prices are high or unpredictable, people may be unable to cool and heat their homes adequately. Such exposure can lead to a host of adverse health outcomes that older adults are particularly susceptible to. These can range from the aggravation of chronic health conditions to food spoilage, undue stress, and even premature death. At the same time, moving toward more sustainable sources of energy that are cost-effective and reliable is increasingly important for older adults, their children, and grandchildren.
