Maine buys a quarter of its electricity from Canada, but of that generated by Maine, about 25% is wind power. I hunted to see if they had trouble with their wind turbines in the winter and didn't find anything. I did find one article mentioning that their efficiency can increase from an average of about 42% to 60% in the winter due to strong north westerlies.
In
2019, about four-fifths of Maine's electricity net generation came from renewable sources. About three-tenths of the state’s total net generation came from hydroelectric dams, one-fourth was fueled by biomass, and nearly one-fourth was provided by wind turbines. Natural gas-fired power plants fueled less than one-sixth of state generation in 2019, its smallest share in at least two decades. A small amount of Maine’s net generation, a total of about 2%, came from solar power, petroleum-fueled, and coal-fired power plants. Another 3% of Maine’s net generation is from facilities that primarily burn black liquor waste from pulp mills or municipal and other solid waste materials....
Maine's power supply has undergone a substantial shift since the early 1990s, when more than three-tenths of the state’s net generation typically came from the Maine Yankee nuclear power station and another one-fifth, on average, from petroleum-fired facilities. The Maine Yankee nuclear plant was decommissioned in 1997, and petroleum-fueled generation has decreased from as much as 37% of net generation in the late 1990s to less than 1% in 2019.
I hate to break it to you, FCT, but we're doing just fine without petroleum fueled power. As a consumer, I can tell you we don't have problems with not enough power, although most of it is from renewable sources. Not every state has as many rivers or trees as we do, but if we can do it, anyone can, using their own resources. It doesn't mean disaster to use renewable energy.

First of all, the EIA summary is talking about percentages for only the power generated in Maine. When you do these percentages as a TOTAL -- they change as they should taking into account that Maine is DEBTOR state with an 25% IMPORT from Canada. Not using that disparagingly. Just stating that maybe that's a good financial move.. (the 25% import, may not exist. You might have seen this number as the % of Hydro imported from Canada, See below)
It's not clear that your 1st sentence is correct, because what I can find says that Maine is about equal on electricity imports and exports anyways.
Let's look at this from Wikimedia commons. It's the latest pie chart i can find on short notice..
KUDOS on cutting back the almost 20% reliance on HEAVY Petroleum generators and coal from 1990s.. A step in the right direction. But your statement that you are not reliant on "fossil fuels" doesnt' recognize Nat Gas as the fossil fuel it is. But it's much cleaner than coal or fuel oil.
Maine is a unique situation because of the abundance of hydro.. And you can GET MORE hydro from Canada if needed and it's available to be sent. This is NOT a "normal" option for MOST of the rest of the USA. Hydro is a stored power source in itself and can be used to "dance in opposite synchrony" with sketchy and unreliable and unschedulable wind investments. Just like I showed in my graph of daily production in Texas ERCOT. It's not a "fast reaction" counter to wind, since you can't change the flow over a dam in minutes or maybe even hours. So Nat Gas will ALWAYS be required to back the wind component up... When in reality, those same nat gas plants could be used SOLELY without the wind investment at all. So the cost of wind of Maine is to have TWO PLANTS when you only need one.. And if you need increased demand. BOTH need to increase. Not just the wind component..
But that huge HYDRO component allows some real savings in CO2 emission ONLY BECAUSE of the dominant hydro component. APPARENTLY -- the strategy for future power to Maine is to rely on MORE IMPORTS of hydro from Canada. But realize that although hydro is listed as a "renewable", it is no longer in favor with the eco-greens and faces much opposition to building NEW dams and even transmission lines. See the following for the dirt..
Is New England’s Biggest Renewable Energy Project Really a Win for the Climate? • The Revelator
Again, the only places in the US that can DO this to any great scale is upper New England, the US Northwest, and in part as an more expensive option for California, Nevada, Arizona..
The Biomass component component of that Pie chart is a eco-disaster. The real pollution from these facilities is substantial.. And Maine might have a great supply "waste wood", but nowadays, there's no such thing as "waste wood" in logging and lumbering.. So additional trees are being cut or they are burning recycled cardboard, tires or god knows what that other Biomass use..
And the solar is a joke. No one above the Mason Dixon line is gonna get any grid scale benefit from solar. It's more of a loyalty pledge to placate idiots.
Sorry for long reply.. But you asked and I take this seriously.. Especially since one of the two articles I have in production right now is entitled "Wind and Solar are Supplements -- Not Alternatives". LOL.... And I've spent most of Jan-Feb getting my research for the piece together..
