  1. This graph and accompanying description is potentially confusing.

    Firstly, it is about electricity, a specific form of energy.

    Secondly, the heading should refer to energy source not fuel source. Solar, and wind are not fuels they are more correctly described as renewable energy sources. Fuels get burnt and/or consumed in the process, usually producing dangerous, polluting waste products, the vast majority of fuels are non-renewable energy sources (firewood is potentially renewable but not in the same sense as wind and solar).

    Thirdly, showing demand on a graph of electricity (MWh) supply is not useful. Showing power (MW) demand makes sense on a graph of power supply because you can have electricity generators generating power but not supplying electricity until they are connected to the grid or other demand. Power supply and demand curves are often quite different.
