Answer:
1. Installing solar panels on the roof. This is an example of renewable energy, and solar panels help provide electricity for a home.
2. Using LED lights instead of traditional lightbulbs. The modern LED lights use much less electricity and function up to 90% more efficiently than the traditional lightbulbs.
3. Using rain barrels to collect water from the roof. Installing rain barrels to collect rainwater to water your plants and garden is a great way to save water and cut down on your water bill.
Hope this helps! :)
