===== I. REPORT SUMMARY =====

1. Recent Trends

1-1 Renewable Power Generation

• In 2015, global renewable electricity generation increased by approximately 5%, accounting for 23% of total electricity generation.
• Solar photovoltaic (PV) capacity grew by 45–50 GW, with China and Japan accounting for over half of this growth.

1-2 Nuclear Power

• Nuclear power generation continued to increase gradually, with seven reactors under construction in 2015.
• Several factors hinder growth: regulatory uncertainty and funding challenges for new plants.

1-3 Natural Gas-Fired Power

• Natural gas demand increased modestly due to policy changes favoring coal in some Asian countries.
• The drop in oil prices made gas less competitive in some markets despite its lower-carbon advantage.

1-4 Challenges and Opportunities

• Electrification of transport and buildings could drive demand for grid flexibility and energy storage.
• Climate agreements like the Paris Accord created new policy opportunities for clean energy deployment.

2. Key Challenges

2-1 Climate Goals and Policy Implementation

• Meeting decarbonization targets under the 2°C Scenario requires accelerating deployment across multiple sectors.
• Many technologies face policy uncertainty, slowing progress toward 2025 milestones.

2-2 Grid Integration Issues

• Variable renewable integration remains a technical challenge, particularly in Europe and Japan.
• Investment in smart grid technologies increased modestly but remains insufficient given growing distributed energy resources (DERs).

2-3 Energy Storage Gaps

• Despite falling battery costs, deployment remains limited due to high upfront costs, especially for residential applications.
• Expansion of larger-scale storage solutions (e.g., flow batteries) remains constrained by planning delays and business model limitations.

2-4 Fossil Fuel Subsidies

• Estimated global fossil fuel subsidies reached USD 230 billion in 2014, creating an uneven playing field for clean energies.

===== II. TECHNOLOGY SPECIFIC ANALYSIS =====

3. Renewable Energy Deployment

3-1 Solar Power

• Utility-scale solar PV costs fell further, with projections indicating additional reductions over 2020–2030.
• Deployment slowed in Europe due to policy uncertainty despite strong growth trajectories previously.

3-2 Wind Energy

• Onshore wind capacity additions increased significantly, particularly in China (33 GW in 2015).
• Offshore wind saw record deployment but continues to face higher costs due to deep-water constraints.

4. Emissions Reduction Pathways

4-1 Transportation Electrification

• Electric vehicles reached 1 million units globally for the first time, driven by supportive policies in Norway, Netherlands, and France.
• Battery costs fell approximately 22% annually since 2010, aligning with reductions previously seen in solar PV development.

===== III. LESSONS AND RECOMMENDATIONS =====

5. Policy Insights

5-1 Carbon Pricing Mechanisms

• Implementing carbon taxes or emissions-based fuel taxes can accelerate clean energy deployment while providing revenue for climate initiatives.
• EU plans to phase out fossil fuel subsidies align directly with renewable expansion goals.

5-2 Technology Accelerators

• Carbon pricing combined with long-term contracts for difference (CfDs) can mitigate investment uncertainty for capital-intensive projects.

5-3 Market Harmonization

• Aligning energy efficiency standards across regional markets reduces compliance costs and leverages economies of scale.

6. Forward Outlook

• Energy storage deployment is poised for acceleration as EV adoption increases and grid demands grow.
• Growth in clean technologies will continue but requires consistent policy frameworks and targeted investments in infrastructure development.
• Strong regional collaboration, exemplified by the Clean Energy Ministerial initiative, appears essential to achieving global decarbonization objectives.
