Energy development is using natural resources to create energy that we can use in our homes, schools, and workplaces. Energy can be produced in different ways, such as using the sun, water, wind, and even the heat from inside the Earth. When the energy is used we can see light, generate heat, or even make things move. Scientists and engineers work together to create new ways to safely and efficiently create energy. Without energy development, we wouldn't have the electricity that powers our lights and appliances.
