energy is important because it helps us use fossil fuel. Fossil fuels are limited and will out one day, but renewable sources will always here. They also create less air pollution, which cleaner air and a healthier planet.

In the , more countries will use renewable energy to meet power needs. It will take time and money build the technology, but it is worth it. energy is the key to a cleaner and world.
