Wind, Solar, or an ETF? Trying to decide what would be the best option.

Extremely new to the stock market in general, but I believe in renewable energy. Trying to decide between VWDRY, VSLR, CAFD, and QCLN. I've looked into each one, and I cannot decide which would be the better long term decision. If you could help me understand which would be better and why, I would greatly appreciate it. Thank you!
