Outdated power grids are emerging as a major constraint on expanding renewable energy, because older electricity networks often cannot absorb all the power produced by new solar and wind projects. PBS NewsHour and The Independent describe the grid problem as a core bottleneck in efforts to shift away from fossil fuels.
This issue is also a focus of the UN climate talks kicking off this week, where organizers frame modern, reliable electric grids as the “backbone” of a clean energy system. Fast Company reports that Turkey and Australia call for more ambitious actions to cut fossil fuels and increase renewables, while also emphasizing grid upgrades. It says the UN has introduced a Global Grids Accelerator, aiming to mobilize funding for infrastructure upgrades in Africa and Southeast Asia, with urgency linked to wider energy-security concerns.
While some outlets provide limited detail, the overall thrust is consistent: scaling up investment and modernization of grids is presented as necessary for renewables to grow fast enough to support climate and energy goals.
