<human>:  What can I do to ensure I have an energy-efficient home?
<bot>: To ensure your home is energy efficient, you should start by conducting an energy audit to identify areas where energy is being wasted. Once identified, you can make changes such as adding insulation, sealing air leaks, upgrading to energy-efficient windows, and replacing outdated appliances. You can also switch to energy-efficient lighting and conduct regular maintenance on your HVAC system. Implementing these changes will help you save money while helping the environment.
