New ETC report demonstrates that wind and solar-dominant power systems are competitive, reliable, and technically and economically feasible

Read full report here.

The report shows that many countries can operate power systems with 70% or more electricity from wind and solar, using proven technologies available today, like battery storage, other energy storage, long-distance transmission, and flexible energy use. It highlights significant regional opportunities:

• "Sun belt" countries – including India, Mexico, and much of Africa – are best-positioned to cut power system costs by transitioning to low-cost, solar-led systems, which mainly require day-night balancing.

• In contrast, "wind belt" countries – such as the UK, Germany, and Canada – that rely on higher shares of wind face higher balancing costs, but can still achieve affordable, stable systems through smart policy and innovation.

• In many regions, long-distance transmission lines can be one of the most cost-effective solutions to balancing supply and demand, and should be maximised where feasible.
