During a kitchen renovation, there are several ways to make your space more energy-efficient. Opt for ENERGY STAR certified appliances, like refrigerators and dishwashers, which consume less energy. Install LED lighting for efficient illumination and consider maximizing natural light with large windows or skylights. Improve insulation to regulate temperature and reduce heating/cooling energy. Incorporate low-flow faucets and aerators to conserve water. Lastly, choose sustainable materials for countertops, cabinets, and flooring to minimize environmental impact. By implementing these energy-saving measures, your renovated kitchen will not only be more eco-friendly but also help lower utility bills in the long run.
