<human>:  How can I make my house more energy efficient?
<bot>: Start by making sure you have proper insulation in your walls and attic. A well-insulated home can help you save up to 20% on your energy bills. You can also reduce your energy use by switching to energy efficient appliances, such as Energy Star-certified dishwashers, fridges, washing machines, and other electronics. Additionally, you may want to look into renewable energy sources, such as solar panels, to power your home. Make sure to take advantage of any local utility company incentives or programs that are designed to help homeowners become more energy efficient.
