NewQ1 2026 Clean Energy Deal Intelligence Report is live

Power 100

The 100 most influential digital voices in US clean energy, ranked algorithmically.

Updated Week 18, 2026·Methodology

How it works: Weighted LeaderRank methodology

Rankings are computed using Weighted LeaderRank (Li et al., Physica A, 2014), a variant of PageRank designed for social influence networks. The algorithm measures who influences the conversation based on real engagement patterns — not follower counts.

Input signals: Twitter replies/quotes/retweets, LinkedIn comments, Bluesky engagement, podcast guest appearances (editorial endorsement), and conference speaking invitations. Platform budgets are normalized so no single platform dominates.

About this ranking: The DealFlow Power 100 identifies the most digitally influential voices in US clean energy based on algorithmic analysis of public social media engagement, podcast guest appearances, and conference participation. It does not measure institutional power, deal size, or policy impact. Rankings refresh weekly.
