A few years ago there was a news report about black lung disease being on an uptick, the highest levels since the early 1970s. It is down somewhat from last year's survey (a five year rolling average), but still close to what it was 50 years ago.

This gives you an idea of what a one-megawatt industrial solar facility looks like, this one down by the Selkrirk Railyard. That said, the 1,000 MW number is a bit misleading, as the 18.7% monthly capacity factor as the panels don't generate any electricity during the night and much less during the winter.
Heating with fuel oil, which is essentially dyed diesel, seems like an odd choice. Oil is expensive, but also is electricity in the Northeast.
In the 1940s through the 1970s, there was a big push to retire both coal power plants and coal heating for reasons of pollution and convenience, and oil seemed like a good drop in replacement, when oil was cheap. But the northeast relying on oil so heavily for power generation, caused electricity to spike in 1970s, which ironically caused some people to swap out electricity for fuel oil. Natural gas supply has traditionally been constrained in New England, which is another reason why the Northeast likes oil so much.
Solar panels are made up of solar cells which are diodes or silicon junctions or check valves that put out 0.5 to 0.6 volts each without load (open circuit). To charge a 12 volt battery, you put 10 solar cells in series to get roughly 20 volts which under load will drop down to closer to 15 volts.
Every solar cell is a diode and not only prevents the backwards flow of current it also prohibits forward flow of current without sunlight to excite the electrons and bridge the junctions.
As solar panels are strings diodes wired in series, if you partially block one diode by providing less light due to a shadow the performance of the entire panel suffers disproportionately. It’s actually bad for the panel to be exposed to shadows continously as when you are blocking flow of current due to shadows you are starting to wear down the silicon junctions in other cells eventually causing permanent damage to the panel.
Little Blue Run Lake or Little Blue Run is the largest coal ash impound in the United States. FirstEnergy owns the site, located in Western Pennsylvania and parts of the Northern Panhandle of West Virginia, and has disposed of billions of gallons of coal waste into the body of water. The lake contains 20 billion gallons of coal ash and smokestack scrubber waste. The northern coast of the lake is only a few hundred meters from the Ohio River, which is the drinking water source for more than three million people.
