Energy systems refer to the methods and technologies used to produce, distribute, and consume energy. These systems can include various sources such as solar power, wind energy, fossil fuels, and nuclear energy. Each source has its own processes for generating electricity or heat, which are then delivered to homes, businesses, and industries. The efficiency and sustainability of energy systems are crucial for addressing environmental concerns and meeting global energy demands. Innovations in renewable energy technologies and improvements in energy storage solutions are helping to create more resilient and eco-friendly energy systems, reducing reliance on non-renewable resources.
