PV is a mess
The plants that build the PV cells have been dumping all the nasty
chemicals used in silicone doping in rivers in China. the PV cells have
finite lifespans of around 20 years; not long enough for them to make
enough energy to cover their production (or purchase!) costs.
Wind has problems, but isn't half so bad.
