What percentage of its potential does Switzerland produce for hydroelectricity?

Switzerland produces 88% of its hydroelectric potential, while Mexico produces 80%. The International Energy Agency forecasted 141 gigawatts generated by hydropower from 2022 to 2027, which is slightly lower than the deployment achieved from 2017 to 2022.
