Method
The 16 of 16 ETFs in the clean energy theme with a filed book, least overlap first, each measured against the S&P 500 holdings ETFIQ reads for the same date. Across the funds listed here the weight held in S&P 500 companies runs from 0.0% to 30.9%. A thematic fund is worth its fee only for the part of it you do not already own. The ranking is the published field sorted, nothing else: no scoring, no weighting and no view on any fund. Every fund ETFIQ covers in this category is eligible, including funds that have closed, because leaving them out would flatter the category.
