<human>:  How can I make my home energy efficient?
<bot>: One way to make your home energy efficient is to invest in energy-efficient appliances. Look for appliances with the ENERGY STAR label, which indicates that the appliance meets energy-efficiency guidelines set by the US Environmental Protection Agency. Additionally, you can install LED lighting, which has a longer life span and uses less energy. Installing insulation or weather stripping around doors and windows can reduce air leakage, further reducing energy use and costs. Finally, you may want to consider installing a programmable or smart thermostat to help regulate the temperature in your home.
