claimSolar and wind energy offer the greatest potential for the energy transition but require advanced energy storage facilities to address their unpredictable and unreliable supply.
claimElectrification of transport reduces fossil fuel consumption in cars, trains, and trucks, provided the electricity is generated from renewable and low-carbon sources such as nuclear, wind, and solar, and supported by energy storage and resilient electricity grids.

claimPower grids that include variable resources like wind and solar require additional power sources for times when electricity demand exceeds wind and solar production.
quoteThe paper on energy storage in California, Wisconsin, and Germany stated: “Wind and solar output exhibit seasonal episodes of both sustained oversupply and undersupply that overwhelm any conceivable storage strategy. Battery storage technologies may have a role in managing shorter-term imbalances but are unlikely to solve the very large seasonal swings in generation output under high-penetration IR (Variable Renewable) scenarios.”
claimEnsuring reliability in power systems with a substantial wind or solar presence requires either deploying extra renewable capacity or including dispatchable technologies in the generating portfolio, absent large-scale energy storage.
claimWind and solar energy generation are weather-dependent and cannot be dispatched, meaning they cannot be turned on at will by grid operators.
claimWhile solar and wind energy are abundant and their technology costs have decreased, these variable renewable technologies face deployment challenges and supply security concerns regarding materials like cobalt and rare earth minerals.
claimRelying exclusively on wind and solar to achieve deep emission reductions is costly and technically challenging because variable renewables require additional power sources to ensure grid stability.
