"If the world is to decarbonise, then more clean energy is needed, fast. [To meet current UNFCCC pledges, countries must] raise global renewable-energy capacity to 11,000 gigawatts (GW) by 2030. [However, supply chain problems and rising interest rates cloud the industry's future. Another obstacle is slow permitting] approval, which delays projects for years and can needlessly tie up capital, lowering returns. [And,] too little development is happening in the global south [because investors require a premium when venturing money in emerging markets]. A last obstacle is protectionism, which raises costs and threatens shortages. . . . Rather than micromanaging production, governments should unleash investment, by acting boldly to strip back permitting rules and ease the risk of projects in the global south [which can come from blending in government money in southern projects that assumes some risk]. They also need to face up to the fact that protectionism frustrates their climate goals. It leads to lower returns, higher prices for power and more broken promises over decarbonisation."
