Building Bridges to a Safe Climate: Sectoral Approaches in Electricity
Introduction
Addressing climate change necessitates a profound transformation in the energy sector, with electricity playing a pivotal role. Electricity generation, predominantly relying on fossil fuels, accounts for over 40% of global energy-related CO2 emissions. Developing countries face particular challenges due to high growth in power demand, which increases the risk of investing in carbon-intensive infrastructure, known as "carbon lock-in."
Key Challenges
- High Power Demand Growth: Developing countries experience rapid growth in power demand, which poses a significant risk of irreversible investments in CO2-intensive technologies.
- Carbon Lock-In: Massive investments in CO2-intensive technologies could make it extremely difficult or costly to stabilize CO2 concentrations at sustainable levels.
Sectoral Approaches
- Technology Mix: The optimal technology mix includes higher generation efficiency, CO2 capture and storage, nuclear power, and renewable energy.
- International Carbon Market: Proposals exist to leverage the international carbon market to drive changes at the sectoral level in developing countries. This involves using carbon prices to influence electricity sector policies.
Case Studies
- Emerging Economies: The book illustrates the advantages and disadvantages of sectoral approaches in key emerging economies like China, India, Mexico, and South Africa.
- End-Use Energy Efficiency: Enhancing end-use energy efficiency is highlighted as a crucial component of the broader strategy to reduce emissions.
Global Perspective
- Global Community Action: Collective action is necessary to mitigate the risk of locking in carbon-intensive infrastructure.
- Post-2012 Climate Policy Framework: The book offers timely insights for the upcoming negotiations on the post-2012 climate policy framework.
Conclusion
Developing countries play a critical role in reducing CO2 emissions from electricity. By adopting tailored policy solutions and leveraging international cooperation, these countries can significantly contribute to global climate goals. The book emphasizes the importance of proactive measures to ensure that future investments in the electricity sector align with the 2°C target.
