Hi Patrick,
It is very hard to answer those types of questions. Why? Because they are not simple to answer. Some are better growth plays, others are income plays and in today's red markets, there may even been some value now. It'll all depend on what it is you are looking for in your portfolio.
Furthermore, there are many different definitions for renewables. Are you looking for utility-types like power generators? Maybe industrials that have tech that will support renewables? Some even classify EV as renewable plays. We'd need more specifics to be able to better provide you with a answer that is worth something. Just spitting out 3 names without context won't provide much value. That being said, we have a few stocks on our Foundational and Bull Lists that fall into this category. BEP on our Foundational list, XBC on our Growth Bull List and AQN/CPX on our Dividend Bull Lists. You can read their reports for our thoughts on those companies which we like quite a bit.
