Renewable Energy has many parts, and some of them can do jobs that others cannot do. It is important to work together to bring the best renewable Energy to the world that we can hope to achieve.
This diagram represents a short overview over different elements of a renewable energy network, and what the different parts can do, and what not.
For example, Hydropower can be both an energy source (flowing water through a turbine) but also a means of energy storage (by keeping the water behind the dam). Renewable Biomass can be stored well, but can also be turned into a renewable source of energy. Batteries can store energy well, but cannot produce energy.

Wood wouldn't be a good option for powering a city, obviously. Neither is coal though.
Global warming isn't going to be solved by a single solution. Wood makes sense for building materials and for heating in rural areas. It's not going to be good for producing electricity, but fortunately there's other technology for that.
Yes, however the article lists it as a power source (of course it's great for building if possible) hence I'm looking at that aspect only. It's more suitable for heating, however, again, at scale it would be problematic (at that's not even a big one) plus emissions are not healthy. If you ignore emissions and use it for heating of few areas here and there (like it is a trend with pellets), taking into account growth rate, it could be a renewable I suppose.
