Since 2016, the United States has acknowledged every first Wednesday in October to celebrate one of the most essential players in combating climate change: energy efficiency. Bringing energy efficiency to the forefront of national observances spurs celebration of the benefits that come with it, such as lowering energy bills, reducing reliance on fossil fuels, and lowering greenhouse gas emissions. Pairing these benefits with improving grid resilience and reliability can create a healthier future for our communities and a true “powerhouse” climate solution.
