"close or equal to"?
really. wow, that's amazing. I would love to hear more about how the pollution involved with manufacturing solar panels, which will then generate many times their energy of manufacturing over the lifetime of the panels, is somehow "close to, if not equal to" that of, say, burning oil for home heating oil, or as gas in cars, or coal for electricity, including THEIR extraction and refining externialities.
be sure to show your work, cause that's quite a doozy of a statement. It reeks of complete bullshit, actually. How many people per year die of solar panel manufacturing related pollution and manufacturing, vs oil production AND POLLUTION AND USE? do the words "orders of magnitude apart" mean anything? check out "smog related deaths" sometime. it's illuminating. and those are generally just talking about people who actually die from the immediate consequences of smog inhalation. now consider the impact on lung disease as a whole. very small doses of critical thinking are all you need.
markets cannot adjust for externialities in any truly meaningful way without very heavy educational loads, especially for complex questions. it is why a slavish devotion to free market principles is childish and shortsighted. it's a frightfully flawed model if actual human welfare is of concern.
