Market size
The global energy consulting market was estimated at $18.7 billion in 2025, according to The Business Research Company. The estimate covers advisory services supporting energy-sector strategy, operations, investment and transition activities.[55]
Forecast & CAGR
The market is projected to grow from $18.7 billion in 2025 to $19.51 billion in 2026, representing a 4.3% compound annual growth rate. Longer-term growth is linked to grid investment, decarbonization, energy-efficiency programs and increasingly complex energy procurement decisions.[55][56]
Market share & regions
Reliable public sources reviewed did not provide a directly comparable regional market-share breakdown for energy consulting. The IEA reported that emerging-market and developing economies outside China attracted 27% of total global energy investment and 18% of clean-energy spending in the latest available analysis, indicating a material but uneven regional opportunity base for consultants.[56]
Segmentation
Published market estimates segment energy consulting by service or product type, including cost reduction and risk management, and by client size such as large enterprises and small and medium-sized businesses. Demand also spans energy procurement, efficiency audits, renewable deployment, grid planning and transition strategy.[58][27]
Trends, drivers & challenges
Energy investment is shifting toward electricity systems, with global energy investment expected to reach $3.3 trillion in 2025, including $2.2 trillion in clean energy. Key demand drivers include electrification, data-center and AI load growth, energy security and decarbonization; challenges include geopolitical uncertainty, changing incentives and slower public energy R&D, estimated at $55 billion in 2025.[56]
Consumer behavior & competition
Energy consulting demand is increasingly shaped by organizations seeking lower energy costs, reliable supply, emissions compliance and investment-grade advice for complex projects. In the U.S. energy-efficiency workforce, 40% of employers hired in 2025 and 74% reported hiring difficulty, particularly for management roles, indicating competition for specialized talent.[57][58]
M&A
M&A activity is supporting consolidation and capability expansion among energy and infrastructure advisers. In 2026, Levine Leichtman Capital Management made a growth investment in Concentric Energy Advisors, a North American utility and energy advisory firm; broader energy-sector M&A also included major utility and power transactions.[59][60]
Regulation
Regulatory requirements remain an important source of consulting work, although the policy direction is changing. The U.S. Environmental Protection Agency proposed ending or narrowing major greenhouse-gas reporting obligations in September 2025, while later EPA notices extended reporting deadlines for 2025 data to March 10, 2027.[61]
Latest news
The latest industry backdrop is a strong but more selective energy-investment cycle: the IEA expects total energy spending to reach $3.4 trillion in 2026, up 5% from 2025, while clean-energy investment remains around $2.2 trillion. In the U.S., the Department of Energy reported 2.36 million energy-efficiency jobs in 2025, down 0.9% year over year but still up 6.5% from 2022.[56][57]
