Nations promise to install more rooftop solar at UN climate talks
The voluntary pledge aims to expand rooftop solar access and cut household power bills as nations seek faster progress on clean energy.
On Tuesday, five countries—Australia, Bangladesh, Kenya, Nigeria, and Vanuatu—endorsed the Global Rooftop Solar Declaration at COP31 in Antalya, Turkey, aiming to double rooftop solar homes from about 150 million to at least 300 million by 2030.
Recent energy shocks from the Russia-Ukraine and Iran wars have accelerated global interest in renewables, driving COP31's focus on electricity access. Turkey now pushes to raise electricity's share in global energy consumption to 35% by 2035.
Lawmakers from 21 other nations, including the United Kingdom, South Africa, and Sri Lanka, endorsed the declaration, alongside Indonesia's state-owned electric power company, Perusahaan Listrik Negara. This broadening support reflects growing momentum for decentralized renewable solutions.
Global Renewables Alliance CEO Bruce Douglas noted that national policies must follow the declaration to ensure success. Governments must prioritize grid upgrades, subsidies for solar panels, and qualified installers to translate these voluntary promises into results.
Balancing renewable growth with coal reliance remains challenging, as coal still accounts for more than 40% of Australia's electricity and 33% of Turkey's. Experts like Nikit Abhyankar of the India Energy and Climate Center warn that insufficient grid capacity risks undermining energy security.
