World Energy Investment Summary (2021)

Core Content

The World Energy Investment report for 2021 outlines the recovery of global energy investment following the impact of the Covid-19 pandemic, highlighting both the rebound in investment and the ongoing challenges in aligning it with climate goals. The report provides a comprehensive overview of investment trends across various sectors, emphasizing the shift towards clean energy and the role of policy and financial support in driving these changes.

Main Points

Global Energy Investment Recovery

Global energy investment is projected to rebound by around 10% in 2021, reaching USD 1.9 trillion, reversing most of the drop from 2020.
This recovery is attributed to both cyclical factors (economic recovery) and structural shifts towards cleaner technologies.
CO₂ emissions are on the rise again, following the largest annual decline in 2020, indicating a gap between climate goals and current investment trends.

Electricity Sector Dominance

The electricity sector is the largest recipient of energy investment, with renewables dominating new power generation investments.
In 2021, global power sector investment is expected to increase by 5%, reaching over USD 820 billion, with renewables accounting for 70% of this total.
Wind and solar PV have seen significant cost reductions and technology improvements, resulting in four times more electricity output per dollar compared to a decade ago.

Policy and Financial Drivers

Government policies and recovery plans are crucial in boosting energy investment, especially in infrastructure and efficiency.
Energy efficiency investments are expected to increase by nearly 10% in 2021, driven by renewed economic growth and initial effects of recovery programmes.
Sustainable finance and green bonds have gained traction, with sustainable debt issuance reaching a record USD 600 billion in 2020.

Clean Energy Investment Gap

Clean energy investment in 2021 is USD 750 billion, which is far below what is needed to avoid severe climate impacts.
To keep temperatures below 2°C, clean energy investment needs to double in the 2020s, and to triple for 1.5°C stabilization.
Emerging market and developing economies (EMDEs), excluding China, are still below pre-crisis investment levels, highlighting the uneven recovery across the globe.

Fossil Fuel Investment Trends

Upstream oil and gas investment is expected to rise by 10% in 2021, but remains below pre-crisis levels.
State-owned companies are becoming more prominent in fossil fuel investment, with Qatar leading in LNG expansion and carbon capture.
The oil and gas industry is beginning to invest in clean energy technologies, though the share of clean energy investment remains low at around 1% of total capital expenditure in 2020.

Coal and Gas

Coal-fired power plant approvals dropped significantly, with a 80% decline compared to five years ago.
China and India are the main drivers of coal investment, with China's coal FIDs at 25% of 2010 levels and India's at less than 5%.
Gas-fired power plant investments remained higher than coal, though the US saw a notable drop in new gas capacity approvals.

Innovation and R&D

Public R&D spending on low-carbon technologies increased to 80% of total energy R&D in 2020.
Private sector R&D spending dropped by 2% due to pandemic-related budget cuts.
Venture capital for low-carbon energy technologies remained resilient, indicating positive signals for innovation.

Key Information

Investment Trends

Global energy investment is expected to rise in 2021, with renewables leading the charge.
Solar PV is projected to outpace wind in 2021, driven by cost competitiveness and existing project pipelines.
Electric vehicle (EV) sales and corporate sustainability targets are driving demand for clean electricity.

Regional Highlights

China and the US continue to attract over half of global power sector investment.
Europe is also showing resilience, with renewables and green recovery packages expected to boost investment.
EMDEs, especially India, Middle East and North Africa, and Southeast Asia, face challenges in recovery due to prolonged crises.

Challenges and Opportunities

Stimulus spending on clean energy is insufficient to ensure a sustainable recovery.
Financial flows are growing faster than actual capital expenditures, highlighting a shortage of viable clean energy projects.
Policy alignment and financial architecture are critical to accelerating clean energy investments and promoting innovation.

Conclusion

The 2021 World Energy Investment report underscores the recovery of global energy investment, the increasing role of renewables, and the urgent need for policy support to align with climate goals. While clean energy investment is on an upward trend, it remains far below the required levels. The gap between investment trends and climate targets is particularly pronounced in EMDEs, and fossil fuel investment continues to dominate, though shifting towards state-owned companies. The report highlights the importance of sustainable finance and policy coherence in achieving a net-zero future.
