Zero carbon electricity: Powering grids with wind and solar

The document asserts that zero-carbon electricity grids are possible and debunks myths regarding the need for fossil fuel backups or the risk of grid overload from renewables. It highlights that wind and solar costs fell by 55% and 85% respectively between 2010 and 2020, and that countries like Denmark, Portugal, and Uruguay are already demonstrating high renewable integration. However, a significant bottleneck exists in grid infrastructure, with 3,000 GW of renewable projects awaiting connection across several major economies. The briefing recommends a cross-sector approach integrating heating, cooling, and industry, alongside investments in digitalisation, storage, and cross-border interconnectors to ensure stability and efficiency.

• Scientific evidence and real-world examples from countries like Portugal, Denmark, and Namibia demonstrate that electricity grids can depend on renewable energy while maintaining a stable supply, debunking the myth that fossil fuel 'backups' are necessary.
• The cost of renewable energy technologies and storage has decreased significantly over a decade; between 2010 and 2020, wind power costs fell by 55%, solar costs fell by 85%, and battery storage costs also dropped by over 85%.
• Insufficient grid infrastructure is a primary obstacle to the energy transition, with 3,000 GW of renewable power projects currently waiting for grid connections across countries including the US, UK, Germany, India, and Brazil.
• Denmark manages excess renewable energy through a combination of storage, heat pumps, flexible pricing, and cross-border interconnectors, and is implementing dynamic line rating (DLR) to potentially increase transmission capacity by up to 30%.
• The deployment of demand-side flexibility in Europe by 2030 could result in annual consumer savings of EUR 71 billion, with electricity costs potentially 64% lower than in scenarios without such flexibility.
• Strategic cross-border interconnectors could save the global economy nearly USD 3 trillion in the transition to net zero by 2040, particularly by enabling the Middle East and North Africa to become energy export hubs.
• The European Union aims for renewable and nuclear sources to provide over 90% of electricity consumption by 2040, while several EU member states and the UK have set decarbonisation targets for their electricity sectors by 2030 or 2035.
