Batteries aren't the only way to store energy. Here's a short list of other ways to store energy: - Pumped hydro: Use electricity now to pump water uphill. When power is needed, water is allowed to flow back downhill, powering a turbine to generate electricity. - Thermal storage: Heat up water or molten salt. This heat can be used directly later (e.g., use hot water for showers) or to power steam turbines to generate electricity - Flywheels: spin up a heavy wheel, which can "smooth" out power delivery when inputs briefly shut off - Compressed air: can be stored / used to power turbines to generate electricity later - Fuel generation: can use electricity during high-production times to generate fuels like hydrogen (electrolysis ) or methane (reverse methanogenesis). None of these are silver-bullets. But if used intelligently for specific problems, they're excellent tools to help cover the volatile output of wind/solar.
