It's just you.
Solar energy is not a sham.
I don't know the way you figure things but I'm sure you've got it wrong.
Who says we need to satisfy world energy needs with just solar PV and
do it all by 2050? Why focus only on PV? Solar thermal is quite useful
and much more cost effective. There are also other untapped staggeringly
huge sources of renewable energy out there in the form of wind, ocean
currents, geothermal, ocean thermal and biomass.
There is even (gasp) nuclear, if we simply must.
I'm not convinced we must.
Solar PV does not add to global warming.
This odd idea seems to be uniquely yours.
PV is useful in some situations today and as it gets cheaper it'll
become more suited for wider applications tomorrow. Perhaps part of
the reason some people install PV is to 'feel good' but that is
certainly not the only reason and probably not the most important.

Theres plenty of differant forms of renewable power that could be
Unfortunately whats always left out of the discussions is who is
prepared to pay for them.
The Chinese Govt certainly isnt which is why they are building a new
1GW coal fired power plant every week.

Well, the USa is yet to demonstrate that it can be done any other way
and lets face it, if they screw the worlds environment, then they are
amongst the least vulnerable.

Actually, those are all solar except geothermal. And in how many
areas is geothermal actually tappable.
It's proven, it works, there have been full scale power plants running
for decades. Operating reactors have been sunk in the ocean, and
other than the families and friends of the crews who sank with them
nobody much noticed.
Replace a patch of partially reflective soil with a solar collector
designed to capture as much energy as possible and you've increased
the energy absorbance of the planet. Do it over enough area and the
effect should be significant.
Is it in fact getting cheaper?
Mostly they do it either because there's a tax incentive or because
they're far enough off the beaten path and have modest enough needs in
the specific application to make solar the best option.
