Key findings

Geothermal power generation in the Sustainable Development Scenario, 2000-2030

Openexpand

Policies are needed to increase the deployment of geothermal power

Geothermal electricity generation increased by an estimated 6% in 2018, much more than the average growth of the five previous years. Nevertheless, the technology is still not on track with the Sustainable Development Scenario, which would require a 10% annual increase in generation over 2018‑30. Policies tackling challenges associated with pre-development risks are needed to increase the deployment of geothermal for power.

Ocean power generation in the Sustainable Development Scenario, 2000-2030

Openexpand

Promotion of research and development is necessary to achieve large-scale deployment of ocean power

Electricity generation from marine technologies increased an estimated 3% in 2018. The technology is not on track with the Sustainable Development Scenario, which requires a much higher annual growth rate of 24% through 2030. Policies promoting R&D are needed to achieve further cost reductions and large-scale development.

Concentrating solar power generation in the Sustainable Development Scenario, 2000-2030

Emphasising plant storage value will be key to attracting investment for concentrating solar power

Concentrating solar power (CSP) generation increased by an estimated 8% in 2018. Nevertheless, CSP is not on track with the Sustainable Development Scenario, which requires annual average growth of almost 26% through 2030. Policy design that emphasises CSP plant storage value will be key to attract additional investment.
