There are many ways to make your home more sustainable and energy-efficient without breaking the bank. Here are a few budget-friendly tips:

1. Seal air leaks: Air leaks can be a major source of energy loss, so it’s important to seal them up. You can use weatherstripping or caulking to seal gaps around doors and windows, and use foam insulation to seal larger gaps around pipes and electrical outlets.
2. Switch to energy-efficient lighting: Replacing incandescent bulbs with LED bulbs can save a lot of energy and money over time. LED bulbs use up to 75% less energy and last up to 25 times longer than incandescent bulbs.
3. Install a programmable thermostat: A programmable thermostat allows you to set different temperatures for different times of the day, so you can save energy when you’re not at home or asleep. Some thermostats can even be controlled from your phone, so you can adjust the temperature from anywhere.
4. Use power strips: Many electronics continue to use energy even when they’re turned off. Plugging them into a power strip and turning the strip off when not in use can prevent this “phantom” energy use.
5. Upgrade your appliances: If your appliances are more than 10 years old, they may be using a lot of energy. Upgrading to Energy Star-certified appliances can save you money on your energy bills.
6. Use low-flow showerheads and faucets: Installing low-flow showerheads and faucets can save a significant amount of water and energy, without sacrificing water pressure.
7. Insulate your home: Insulating your home can prevent heat loss in the winter and heat gain in the summer, reducing the amount of energy needed to heat and cool your home.
8. Use natural light: Open curtains and blinds during the day to let in natural light instead of using artificial lighting.
9. Plant trees: Planting trees around your home can provide shade in the summer and act as a windbreak in the winter, reducing the amount of energy needed to heat and cool your home.

These are just a few ways to make your home more sustainable and energy-efficient on a budget. Start with one or two changes and gradually add more over time to make a bigger impact.
