Energy is the capacity to do work and powers every aspect of our lives. It comes in various forms, such as electricity, heat, and mechanical energy, and can be derived from renewable sources like wind, solar, and hydropower, or non-renewable sources like fossil fuels and nuclear power. As the demand for energy grows, the focus is shifting toward more sustainable and cleaner energy solutions to reduce environmental impact and combat climate change. The efficient generation, storage, and consumption of energy are essential for a sustainable future.
