Without that overhaul, countries risk missing their climate goals and worsening climate-related disasters like storms and fires that are already walloping power grids.

Today’s aging grids are often teetering on the edge of power shortages, something that could become an even bigger problem as homes, buildings, and transportation go all-electric.

“We are heading fast towards an electric future, and grids are the weakest link,” Dave Jones, global insights lead at energy think tank Ember, said in an emailed statement.

It’s all part of countries’ combined efforts to limit global warming to the Paris agreement target of roughly 1.5 degrees Celsius above preindustrial levels, a goal the World Health Organization says could prevent millions of climate change-related deaths.

“The recent clean energy progress we have seen in many countries is unprecedented and cause for optimism, but it could be put in jeopardy if governments and businesses do not come together to ensure the world’s electricity grids are ready for the new global energy economy that is rapidly emerging,” IEA executive director Fatih Birol said in a press release.

If a lack of investment in grids leads to slower deployment of renewables, the IEA report says, then carbon dioxide emissions increase by 60 billion metric tons between 2030 and 2050.
