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.

This distinction is important. I’ve seen a lot of greenwashing about hydrogen as a renewable energy source, but it is only a non-carbon producing form energy storage, and is almost entirely energy stored from processing fossil fuels.
Creating it from electricity is highly inefficient, so that’s why it’s made from other fossil fuels (that in theory would have been wasted). If hydrogen was easily compacted and stored long term it would work, but those are the biggest problems it faces, along with having a much lower energy density that fossil fuels. Hard to beat those carbon bonds without going nuclear.
