The primary technology used in renewable energy systems includes solar panels, wind turbines, and energy storage systems like batteries. Solar panels convert sunlight into electricity through photovoltaic cells, while wind turbines harness wind energy to generate power. These technologies are designed to produce clean, sustainable energy, minimizing reliance on fossil fuels. Innovations in energy storage technology, such as lithium-ion batteries, enable better efficiency and reliability, allowing for energy to be stored and used when demand arises. Collectively, these technologies support a transition towards greener energy solutions.
