In the five years since its launch, the Clean Energy Transitions Programme (CETP) has become the largest and most important programme at the International Energy Agency (IEA).

Ever since its inception, the G20 Energy Transitions Working Group (ETWG) has covered a wide range of priority areas broadly spanning across clean energy, energy access and energy security.

Clean energy development for almost all G20 countries, be it developing or developed, stands at restricted levels for green hydrogen produced from biomass for heat and electricity.

Renewables are growing rapidly in the electricity systems around the world as countries seek to improve their energy security, meet emission reduction targets and take advantage of cheaper electricity sources.

The rapid adoption of renewable energy (RE) will not only help decarbonise the world’s electricity systems but also help realise the desired impacts of our Sustainable Development Goals (SDGs).

Among the broad range of renewable energy options available within the global energy transition, ocean energy offers significant potential to support decarbonisation efforts. With a global market potential of 350 GW by 2050, ocean energy can provide clean, local, predictable electricity to coastal nations and islands around the world.

Transitioning towards a clean energy future is a mainstay of the global efforts to achieve the Paris Agreement’s climate goals.

The Covid-19 pandemic and Russia’s invasion of Ukraine have led to major disruptions to global energy and technology supply chains. Soaring prices for energy and materials, and shortages of critical minerals, semiconductors and other components are posing potential roadblocks for the energy transition.

A wide range of countries make efforts to track their entire national public energy research, development and demonstration (RD&D) activity on an ongoing basis, also sharing the collected data with the IEA through a standardised template. However, the approaches adopted to collect data vary significantly across countries.

Secure, resilient and sustainable energy technology supply chains are central to successful clean energy transitions.
