Summary of Global Energy Review 2020: Impacts of the Covid-19 Crisis

Core Content

The IEA Global Energy Review 2020 provides a comprehensive analysis of the impact of the Covid-19 pandemic on global energy demand and CO₂ emissions. The report highlights how the pandemic has created an unprecedented economic and energy crisis, with significant implications for the future of energy markets and environmental outcomes.

Main Points

• The Covid-19 crisis has led to unprecedented containment measures, affecting 50% of global energy use by mid-April 2020.
• The global energy demand declined by 3.8% in the first quarter of 2020, reversing all the growth seen in 2019.
• CO₂ emissions also saw a dramatic drop, with a reduction of over 5% in Q1 2020, marking the largest decline in emissions since the end of World War II.
• The annual energy demand is projected to fall by 6%, the largest decline in 70 years, and more than seven times greater than the impact of the 2008 financial crisis.
• Renewables are the only energy source to see growth in demand, driven by low operating costs and priority dispatch.
• Coal demand dropped by 8%, primarily due to reduced electricity demand and increased competition from cheap gas and renewables.
• Oil demand fell by 5% in Q1, and could decline by 9% annually, returning to 2012 levels.
• Gas demand is expected to fall much further than in Q1, due to reduced usage in power and industry.
• Nuclear power demand also declined due to lower electricity demand.
• Biofuels are likely to see a decline in demand due to reduced transport activity.
• The shape of the recovery will significantly affect the overall impact on energy demand and emissions, with U-shaped recovery being the most likely, accompanied by a permanent loss in economic activity.

Key Findings

• Global energy demand in Q1 2020 was 3.8% lower than in Q1 2019.
• Coal demand fell by almost 8%, with China being the hardest-hit country.
• Oil demand dropped by nearly 5%, mainly due to mobility restrictions and aviation curtailment.
• Gas demand fell by around 2%, with low prices mitigating some of the impact.
• Renewables increased in demand by 1.5%, with renewables' share in electricity generation rising to 27.5% in Q1 2020.
• Electricity demand dropped by 20% or more in full lockdown periods, with renewables being the least affected.
• CO₂ emissions fell by 8% in 2020, or 2.6 Gt, reaching levels similar to 2010, and this would be the largest year-on-year reduction ever recorded.
• The rebound in emissions could be larger than the decline, unless cleaner energy infrastructure is prioritized in economic recovery efforts.

Regional Impacts

• China was the first to implement lockdowns and experienced a 7% drop in total energy demand.
• United States saw a 6% decline in energy demand, with milder weather contributing to the drop.
• European Union had a 5% decline in energy demand, primarily in March.
• India initially saw 0.3% growth in energy demand, but the full lockdown in late March led to a significant drop in Q2.
• Korea and Japan had less stringent lockdowns, resulting in below 10% energy demand reduction.

Uncertainties and Scenarios

• The full-year projection depends on the duration, stringency, and spread of lockdowns, as well as the speed of recovery.
• A base case scenario suggests a 6% decline in annual energy demand.
• Downside risks include longer lockdowns, second waves of the pandemic, and global supply chain disruptions.
• Upward risks include a V-shaped recovery with effective virus suppression and ambitious macroeconomic policies.

Policy Implications

• The recovery from the lockdown recession will be gradual, leading to a deep post-war recession.
• Macroeconomic policies must focus on cleaner and more resilient energy infrastructure to avoid a rebound in emissions.
• The impact on CO₂ emissions is highly asymmetrical, with low-carbon sources far outpacing coal in growth.

Conclusion

The Covid-19 pandemic has created a unique and unprecedented situation in the global energy market, with drastic declines in demand and CO₂ emissions. The long-term economic and energy impacts will depend on the recovery trajectory and policy responses, with renewables emerging as the most resilient energy source. The IEA emphasizes the importance of clean energy investments to ensure a sustainable recovery.
