Perfectly said. People think that we can just "go solar" but fail to consider its limitations, especially in VT.

Yeah, it's a tough sell for a cloudy, northern state to be dependent on a resource that relies on clear skies and long daylight hours.

But not hopeless- I’ve produced about 5000 more kWh than I’ve consumed YTD from my solar array.

Yeah solar actually works pretty well. And you can have standby power plants that operate on natural gas in case of emergency.

I’m more in the “PV, wind, nukes and storage” camp myself!

Germany is one of the largest solar producers. And its further north than us.

Sure, I'm not arguing it's impossible. It's definitely a solution that can work, my take is just that it's not the most efficient solution. If you look at energy sources in terms of comparative advantage, it doesn't really make sense.

If I had to wager why Germany has so much solar energy, I'd guess it's the same reason that Vermont has so much solar energy. We have some of the most expensive energy in the country in Vermont. The only remedy that an individual household has for that is to a) reduce their energy consumption, or b) produce their own energy. For the environmentally conscious consumer, they really only have way to generate their own power. Buy solar panels.

If you do a cost-benefit analysis, it's actually a much better ROI to buy solar panels if you live in VT than if you live in AZ. That's not because the solar panels produce more energy here, it's because even if they produce half the energy of a panel in AZ, it still offsets more cost for the end-user due to our high energy prices. I'm guessing that's exactly why Germans use so much solar energy. Energy is expensive, and solar is the only way they can make their own. Whether it's efficient or not doesn't matter when it's the only game in town.

My "it's a tough sell" take assumes that the end goal is to reduce total consumption, though. It's not enough to just replace the oil and gas industry with a wind/solar/hydro industry, the end goal should be to reduce the total amount of resources required to produce energy and simultaneously reduce the total energy demand.

With that background, I stand by my statement. It's a tough sell, and the reason it's a tough sell is because solar is fundamentally not an efficient means of producing energy in Vermont. In AZ, they might be able to replace one nuclear power plant with 1,000,000 solar panels. In Vermont, though, it might take us 3,000,000 solar panels. In that scenario, we've effectively wasted 2 million solar panels worth of material for no good reason, since the output of the nuclear power plant was constant and didn't change based on climate. I'd share the same criticism of Germany. Solar panels contain heavy metals which are destructive to mine and more destructive to dispose of. Right now, most of them come from Xinjiang where they're manufactured by Uyghur Muslims in forced labor camps. We shouldn't be using them if they're not an efficient solution.

IMO it's easy to make the case "I should buy a solar panel" here, but it's really hard to make the case "Vermont should invest in solar energy". We just don't have the climate for it. There are solutions that are not only more cost effective for our state, but also fundamentally less damaging to the environment.

Subsidies...(Tax benefits).

Right. But the fundamental question is not which solution has the lowest dollar cost to the end user after subsidies. The question is which solution produces the most energy balanced against the lowest environmental impact.

Private investors don't foot the bill 30 years from now when heavy metals are leeching into the soil around a landfill. What a private investor does today is absolutely irrelevant to the question at hand. If it were, well, why aren't we just going all-in on oil and gas? It has by far the largest market share. Private investors love the fossil fuel industry. It must be the future, then, right?

Yea? How is that working out for them?

They are far more dependent on Oil and Natural Gas than they were 20 years ago before the green party destroyed their nuclear power.

There is no energy future without nuclear getting us there first. Vermont produced LESS carbon before Vermont Yankee was closed, so we went YEARS backwards because Shumlin was an idiot.

Germany may not be the best argument for going green. Despite all of there solar generation they are genuinely worried that people are going to freeze to death this winter because of the energy crisis.

We have lots of open unused fields that are perfect for solar arrays. Combined with power storage solar is actually pretty good in vt.

What storage are your referring to? The vast majority of solar installations do not include any significant energy storage infrastructure as far as I'm aware. Batteries are very expensive and not very good for the job.

I certainly hope you're right, but I've been around too long not to be at least a little skeptical of new revolutionary battery startups. I'll believe it when I see it, just like all the other largely theoretical grid level storage solutions. I don't want our strategy be naive trust that currently-intangible technologies will save us sometime in the indefinite future, I would rather see us invest in tried and true solutions like nuclear and offshore wind, and do it NOW.

I just meant we have lack of sun in VT. Also, we don't have great/affordable storage.

What about winter when there is less sun and snow covers the panels? Also battery storage is prohibitively expensive right now. We could put wind turbines on hillside maybe but that means cutting down trees.

Precisely. The wind doesn't always blow nor does the sun always shine. We need a reliable grid and the grid needs reliable sources of generation.
