Are there any other soures of data on the percentage of renewables besides CoinShares ?

" The CoinShares Group is a pioneer in digital asset investing. Our team launched the world’s first regulated bitcoin investment fund in 2014, offered the world’s first bitcoin based securities on a regulated exchange in 2015, and have built investment firms in commodities, precious metals, and now digital assets"

Something about thisstatement leads me to believe they could have a potential conflict of interest.
