      @562enek22 that is a difficult one, I am not sure is there a best one as we need all of them we can to try stop climate change. Here in Ireland, we use a lot of wind power but in sunnier countries, they use more solar power so it can depend on the country what renewable energy source is used more. There is also bioenergy from plants and this is good as it can also be used for heating and in the transport sector for things like fuelling trucks that electricity might not be very good at yet.

      @Emma is completely right! In terms of energy, there is not a single answer. At the end, it all depends on what forms of energy are available in the region you want to provide for, and what applications the energy is needed for.

      There is also the need to replace fossil energy and fossil materials to produce items we use every day, for instance, plastics. You need energy (which can be provided by solar/wind sources), but you also need plants (bioenergy) to provide for the starting matter that will end up as plastics.
