Energiespeicher, or energy storage, refers to technologies that capture and store energy for later use. These systems are essential for balancing supply and demand, especially with renewable energy sources like Solarenergie and Windenergie, which can produce energy intermittently. Common types of energy storage include batteries, pumped hydro storage, and compressed air systems. The primary goal of Energiespeicher is to enhance energy efficiency and reliability. By storing excess energy during low-demand periods and releasing it during peak demand, these systems help stabilize the grid and reduce reliance on fossil fuels. This contributes to a more sustainable energy future.
