Public Banks Could Unlock $28B More for Clean Energy

Government-owned banks across the world's largest economies are sitting on an untapped goldmine for fighting climate change, and some countries are already striking it rich.

A groundbreaking report from Oil Change International reveals that national development banks in G20 countries invested $36 billion annually in renewable energy over the past decade. The real news? They could immediately add another $28 billion each year simply by shifting money away from fossil fuels to clean energy.

These aren't distant international institutions. National development banks are publicly owned financial powerhouses that invest directly in their own countries' futures. Unlike private investors chasing quarterly profits, they can fund long-term projects that create local jobs and keep energy affordable for everyone.

Mexico is leading the charge with an inspiring vision. President Claudia Sheinbaum's government is coordinating its development banks to achieve universal energy access, including a plan to provide free solar panels to low-income families vulnerable to dangerous heat waves. It's renewable energy as a human right, not a luxury.

Germany and Brazil are using creative public financing tools to pump billions into clean energy through their established development banks. The UK's new National Wealth Fund could follow suit by using public bonds to build green industries and publicly owned infrastructure from the ground up.

The report analyzed nearly 8,000 transactions from 54 institutions between 2016 and 2024, creating the first comprehensive picture of how these banks fund energy. The data is now publicly available so citizens can hold their governments accountable.

The Ripple Effect

When national development banks invest in renewable energy, the benefits multiply across communities. Local workers get trained in solar installation and wind turbine maintenance. Energy costs stabilize because sunshine and wind don't have volatile global prices. Countries build energy independence instead of relying on imported fossil fuels.

Costa Rica's Banco Popular demonstrates another breakthrough: democratic governance. The bank is steered by the public and national stakeholders like unions, ensuring investments reflect what communities actually need.

Not every country is seizing this opportunity yet. South Korea and Canada have powerful development banks that could reshape their economies but currently fund fossil fuels overwhelmingly. The report shows these institutions could pivot toward renewables and become climate leaders overnight.

The timing matters. Many governments, especially in developing nations, face crushing debt and unfair trade rules that limit their ability to invest in clean energy. National development banks offer a way forward that doesn't require waiting for international negotiations or private investors to decide the transition is profitable enough.

"National development banks can finance renewable energy jobs, provide universal energy access, and strengthen public services," said Adam McGibbon from Oil Change International. "Unlike private investors focused on short-term returns, they can invest for the public good."

The tools to build a clean energy future are already here, publicly owned and ready to deploy.
