An energy community is a group of people who work together to create and use energy in a better way. Just like how you and your friends work together to build a sandcastle, energy communities work together to save energy and use renewable energy sources like sunlight and wind power.
Think of it like this: you and your friends live in a neighborhood and share a playground. You can work together to keep the playground clean and fun for everyone. Similarly, people in energy communities live close to each other and share energy resources. Instead of every person using their own energy source, they work together to use one that is better for the environment and cheaper for everyone.
Energy communities also help to reduce greenhouse gas emissions which can be bad for the earth. By sharing energy sources and using renewable energy, they can reduce their carbon footprint and help to protect the planet for the future.
