Energy transition planning helps companies move from fossil fuel consumption to cleaner systems. However, it requires a strategic roadmap as the work grows more complex each year, with technology shifting faster than expected and regulations tightening. Teams traditionally rely on internal expertise and scattered market data and while those inputs help, they rarely provide the independent benchmarking or industry-wide insight necessary for confident planning. These top consulting firms offer sector-specific know-how in designing transition strategies that match real-world constraints.
