Climate justice 'cornerstone' of COP28 agreement, taking Global South concerns 'into account' More than 100 countries at the COP28 climate summit in Dubai have agreed to triple renewable energy capacity by 2030 - one of the least controversial commitments floated at the conference. But they have given little detail on how they can make an industry running flat out go that much faster. "It is realistic, but there are elements that need to be solved; permitting, leases, grid connections," Anders Opedal, chief executive of Norway's Equinor, a major renewable energy developer, told Reuters. Renewable energy is key to meeting the 2015 Paris climate agreement to limit global warming. And while renewables are already expanding fast, this latest goal would require solar and wind power deployments to speed up a lot. The tripling target would bring global renewable energy capacity to at least 11,000 gigawatts (GW) in just six years - more than 20% higher than current projections from BloombergNEF of around 9,000 GW by that time. That would mean pumping up investment in renewables, which the International Energy Agency (IEA) says hit $600 billion globally last year, at a time some investors are retreating due to higher borrowing costs. But the problems extend far beyond that. Across the renewables industry, there are signs of strain. Supplies are short of everything from wind turbines to transformers. There is a labour shortage. The cost of wind and solar projects has spiralled up. And local opposition to big energy projects has slowed layered bureaucracy with years-long processes to get permits.
