You can be 100% assured that if anybody wants to talk to you about "the costs of solar power" then it is a rep of the Neandertalers-Industry in full smokescreen operation mode.
These discussions are a great example for how propaganda works.
It does not make sense to calculate the "costs" of freedom, independence and the health of your family.
Also the real costs of unresolved nuclear waste problems, huge wars for securing oil supply and the contamination of our ground water by primitive fracking techniques are... titanic.
We need more young people in the US to take over the general political and economic discussion. Old and greedy neandertalers are destroying the living environment of young people, not ok, must change.
Homo sapiens, sapiens (!), take over please...
