The price, without tax credits, has gone down on solar panels by 1/5 since I started pricing them 5 years ago. When I bought them last year they were only $1 per watt, all while the price of gasoline went up.You haven't shown any correlation between the two. The price of solar and wind have been reduced by increased subsidy, not a lessening of manufacturing cost.
The point is, that is changing as more people like myself install affordable onsite systems.Not "so many of us", a few of us. And what we generate is nowhere near our need. So the vast majority rely upon transmitted power from a distant location.
The 49% is from government statistics. With new research, we may find other more abundant materials that work better than lithium. That's the point of research.First, that 49% is a little high, regardless, you're trading one shortage for another. Electric cars rely upon rare earth metals that internal combustion engines don't. Let's just take ONE of them - lithium. Are you of the impression that lithium is of unlimited supply or renewable?
Affordable oil is finite as well and burning it for transportation is damaging the environment.
