Energy is the ability to do work or produce change. It exists in various forms, including kinetic, potential, thermal, and chemical energy. Energy is essential for powering our homes, vehicles, and industries, and it plays a crucial role in our daily lives. Renewable energy sources, such as solar, wind, and hydropower, are becoming increasingly important as we seek to reduce our reliance on fossil fuels. These sustainable options help mitigate climate change and promote a cleaner environment, ensuring that future generations have access to the energy they need.
