Of course they can't do it with wind or solar. The prices are to high for each and they need replacement regularly and maintenance that is really expensive like the mechanical work in a tower for wind as in replacing gears in the generator or a blade on one waiting for a windless day. They completely left out methane as in using the sewage systems in large cities as methane producers and that produces methane 24/7 but far from enough. Hydrogen seeps through the atoms of it's storage containers since it's the smallest atom and needs to be supercold at all times or explodes so that is something that is far to dangerous. Now a form of nuclear where recycling the fuel safely instead of burying it is what is really needed and maybe methane for vehicles since the rare earths needed for electric cars have their mines in Africa and other nations owned by China so that is out and far to expensive and the lithium batteries are far to dangerous where a solid or other form of battery is really needed or something we haven't even considered or invented yet.
