Perovskite-silicon tandem solar cells achieved about 29% efficiency on commercial-size cells, exceeding traditional silicon panels. Bifacial solar panels boost energy yields by up to 30% in reflective environments such as snow or sand. Floating solar farms can raise output by roughly 15% due to water cooling of the panels. Covering 10% of the world’s reservoirs with floating solar could yield about 20 TW of capacity, roughly 20 times today’s global solar capacity. Offshore wind turbines now reach 15–18 MW per turbine, enabling major capacity gains in deep waters. Floating offshore wind pilots have been launched by Norway, France, and Japan,
