Only 4 out of 38 clean-energy technologies are on track to meet long-term climate goals
23 May 2018
The International Energy Agency’s new and most comprehensive analysis of the clean-energy transition finds that only 4 out of 38 energy technologies and sectors were on track to meet long-term climate, energy access and air pollution goals in 2017.
Some technologies made tremendous progress in 2017, with solar PV seeing record deployment, LEDs quickly becoming the dominant source of lighting in the residential sector, and electric vehicle sales jumping by 54%. But IEA analysis finds that most technologies are not on track to meet long-term sustainability goals. Energy efficiency improvements, for example, have slowed and progress on key technologies like carbon capture and storage remains stalled. This contributed to an increase in global energy-related CO2 emissions of 1.4% last year.
TCEP provides a comprehensive, rigorous and up-to-date analysis of the status of the clean-energy transition across a full range of technologies and sectors, their recent progress, deployment rates, investment levels, and innovation needs. It is the result of a bottom-up approach backed by the IEA’s unique understanding of markets, modeling and energy statistics across all fuels and technologies, and its extensive global technology network, totaling 6,000 researchers across nearly 40 technology collaboration programmes.
The analysis includes a series of high-level indicators that provide an overall assessment of clean energy trends and highlight the most important actions needed for the complex energy sector transformation.
For the first time, the analysis also highlights more than 100 key innovation gaps that need to be addressed to speed up the development and deployment of these clean energy technologies. It provides an extensive analysis of public and private clean energy research and development investment. It found that total public spending on low-carbon energy technology innovation rose 13% in 2017, to more than USD 20 billion.
“There is a critical need for more vigorous action by governments, industry, and other stakeholders to drive advances in energy technologies that reduce greenhouse gas emissions,” said Dr Fatih Birol, the IEA’s Executive Director. “The world doesn’t have an energy problem but an emissions problem, and this is where we should focus our efforts.”
A total of 11 of 38 technologies surveyed by the IEA were significantly not on track. In particular, unabated coal electricity generation (meaning generation without Carbon Capture, Utilisation and Storage, or CCUS), which is responsible for 72% of power sector emissions, rebounded in 2017 after falling over the last three years.
Meanwhile, two technologies, onshore wind and energy storage, were downgraded this year, as their progress slowed. This brought the number of technologies “in need of improvement” to a total of 23.
This year, the TCEP tracks progress against the Sustainable Development Scenario, introduced in the World Energy Outlook 2017, which depicts a rapid but achievable transformation of the energy sector. It outlines a path to limiting the rise of average global temperatures to “well below 2°C,” as specified in the Paris Agreement, as well as increasing energy access around the world and reducing air pollution.
In this scenario, meeting long-term sustainability goals requires an ambitious combination of more energy efficient buildings, industry and transport, and more renewables and flexibility in power.
The findings this year are compiled in an updated website, which provides easy navigation across technologies and sectors, and draws links across the IEA’s resources. The report will be updated throughout the year as new data becomes available, and will be complemented by cutting-edge analysis and commentary on notable developments on the global clean energy transition.
The findings for each technology and sector will be updated on a continuous basis with the latest information and findings from the IEA. Find out more at www.iea.org/tcep/.
