Top 10 energy investors, ranked by recent fund activity

Among firms with a published profile and a dated fund or deal in the last 24 months. The rule: Activity score out of 100: recency of the latest fund filing or dated deal (40: within 3 months 40, 6 months 30, 12 months 20, 24 months 10), share of the observed portfolio in this sector (30; 15 when the sector is stated only), size of the fund on file on a log scale (20) and completeness of the public record (10). It is a measure of activity and fit, not of quality or returns. The same rule orders the whole list; it is repeated in the method box.
