Yea, that website doesn't have a dog in this hunt now does it.. The US Department of Energy's numbers are flat wrong then? In the USA, I don't think so.
Look, you can believe what you want and come up with links to "prove" your view, but if you are choosing to ignore the data provided by the US Department of Energy, you are going to have to endure the scorn you richly deserve. I'm not saying the government data is correct in all cases, only that the department of Energy is about as close as you can get to an unbiased opinion, at least for the costs of energy production in the USA.
PV Solar is not a viable solution and another 40% cost drop is not in the future. The DOE says that PV Solar is at least 4 times more expensive. This isn't going to change all that much for various reasons, chief of which is that it will only work when the sun shines. The sun never shines at night and during the day it can be hit and miss, which contributes to a "availability factor" of about 25% (in sunny areas) or much less (in cloudy areas). Try as you might, you cannot fix that with technology. Don't start down the path to thinking that we can just store excess then use it when we need it later, that drives the "cost" of solar up by another factor of 4 (or more) due to conversion losses, and makes your position logically even worse.
