Renewable Energy Storage

Renewable energy storage involves capturing excess energy generated from sources like solar and wind, and saving it for later use. Since these sources are intermittent—producing power only when the sun shines or the wind blows—storage ensures a steady energy supply regardless of weather or time. Common methods include batteries, which store electricity chemically; pumped hydro, which uses excess energy to move water to a higher reservoir; and other technologies. This enables reliable, consistent delivery of clean energy, reducing reliance on fossil fuels, lowering emissions, and supporting the transition to sustainable power systems.
