A critical driver of clean energy transitions

Through research, investments and collaboration, a wide variety of energy fields are being reshaped by technology improvements, reducing costs, increasing efficiencies and boosting deployment. Effective policies are needed to support the best ideas from lab to market.

Key findings

Spending on energy RD&D by national governments, 2014-2018


Public energy RD&D spending is not expanding enough

While public energy RD&D spending rose modestly in 2018, led by the United States and China, its share of gross domestic product remained flat and most countries are not spending more of their economic output on energy research.
Our work on innovation

The energy sector has a long history of disruptive innovation leading to sweeping changes in energy markets, mobility and society at large. Governments are increasingly looking to guide and accelerate the development of technologies for energy transitions and competitive advantage in a changing energy system. The IEA works with policy and decision makers around the world to track public and private research, development and demonstration (RD&D), share good policy practice and promote multilateral collaboration.
