Hydrogen vs. Battery Electric Cars

One issue regarding hydrogen fuel is where do we get the energy to obtain the hydrogen, but that is also true of battery power, what is the point of charging a battery using electricity from a regular power station? Can we provide sufficient energy using "renewables"? My thoughts are we need to have nuclear power stations to provide sufficient carbon zero energy to do both. Nuclear power is the only way forward from carbon based power supplies. 

Also remember that so called "renewables", such as wind and solar require equipment that is fabricated from toxic and non-biodegradable materials, they too have a carbon footprint as well as an environmental impact footprint. 

I am all for moving away from "fossile fuels" but we must recognise the downsides to otherwise idealised concepts such as wind and solar (what happened to wave?) power. Nuclear energy has a bad reputation but it cannot be dismissed as it may be our only real hope of achieving a carbon zero world and solving climate change.

BTW. Just to upset the vegans, studies suggest vegans may emite three times more greenhouse gases than people who eat a normal diet including meat. Okay, I may have made that one up, but you never know... ;D
