Summary of Tracking Clean Energy Progress 2015

Overview
The report analyzes the state of clean energy technologies and progress toward decarbonizing the energy sector as part of achieving climate change mitigation goals. The analysis evaluates technologies across key sectors and assesses global deployment trends against the 2°C Scenario (2DS), a pathway to limit global temperature rise to 2°C above pre-industrial levels. Progress is tracked through quantitative indicators, and recommendations highlight the need for stronger policy actions, international collaboration, and innovative solutions.

Progress and Challenges

• Clean energy technologies, including renewables, nuclear power, and energy efficiency, have shown progress, but most are not meeting their 2DS targets.
• Renewable power generation continues to grow, though its overall annual additions have leveled off, caused partly by policy uncertainty and barriers in OECD and non-member economies.
• Nuclear power growth is projected, with high construction numbers in some countries, but global deployment remains slow in meeting decarbonization goals.
• Barriers to deployment include policy uncertainty, financing challenges, lack of infrastructure, and technological lock-in in energy-intensive sectors.

Key Findings Across Sectors

• Renewable Power: Solar photovoltaic (PV) capacity growth is aligned with 2DS targets, but onshore wind and hydropower deployment needs improvement. Geothermal, offshore wind, and bioenergy face technology-specific challenges.
• Nuclear Power: Deployment has increased, especially in China and the UAE, but investments and grid integration require acceleration.
• Natural Gas-Fired Power: Natural gas has struggled to compete with low-cost coal due to price fluctuations, though it still plays a role in reducing the carbon intensity of power generation.
• Coal-Fired Power: Coal remains the fastest-growing fossil fuel, driven by demand in emerging economies. However, energy efficiency and carbon capture and storage (CCS) advancements are critical to meet climate goals.
• Carbon Capture and Storage (CCS): Deployment has reached a milestone, but investment in CCS demonstration projects remains insufficient to meet 2DS.

Policy Recommendations

• Strengthen incentives and regulations to stimulate market certainty, especially in OECD countries and emerging economies.
• Increase public and private investment in research, development, and demonstration (RDD&D) for key technologies like CCS, advanced nuclear, and energy storage.
• Support early actions on energy efficiency across sectors to contribute to short-term emissions reductions.
• Enhance data collection and metrics to accurately track progress and develop robust frameworks for monitoring decarbonization efforts.

Metrics for Energy Sector Decarbonization

• The report emphasizes the need for diverse metrics, including energy and emissions intensity indicators for supply and demand-side trends.
• Energy efficiency measures, renewable deployment, and low-carbon power generation should be prioritized to achieve near-term, deep, and long-term reductions.

Conclusion
Unprecedented action is required to unlock the full potential of clean energy technologies. Faster deployment, improved policy frameworks, and sustained international collaboration are essential to meet shared climate goals.
