Perhaps. Many people in America also claim to care about the environmental impact of a number of things. I think many more people care performatively than transformatively. Personally, I don't worry too much about it. It feels like a lost cause and my personal impact is likely negligible in the end.
Then offsetting that cost to a cloud provider isn't any better.
450W just isn't that much power as far as "environmental costs" go. It's also super trivial to put on solar (actually my current project - although I had to scale the solar system way up to make ROI make sense because power is cheap in my region). But seriously, panels are cheap, LFP batteries are cheap, inverters/mppts are cheap. Even in my region with the cheap power, moving my house to solar has returns in the <15 years range.
If you provide for yourself (e.g. run your IT farm on solar), by all means, make use of it and enjoy it. Or if the consumption serves others by doing wind forecasts for battery operators or hosts geographic data that rescue workers use in remote places or whatnot: of course, continue to do these things. In general though, most people's home IT will fulfil mostly their own needs (controlling the lights from a GPU-based voice assistant). The USA and western Europe have similarly rich lifestyles but one has a more than twice as great impact on other people's environment for some reason (as measured by CO2-equivalents per capita). We can choose for ourselves what role we want to play, but we should at least be aware that our choices make a difference
In America, taxes account for about a fifth of the price of a unit of gas. In Europe, it varies around half.
The remaining difference in cost is boosted by the cost of ethanol, which is much cheaper in the US due to abundance of feedstock and heavy subsidies on ethanol production.
The petrol and diesel account for a relatively small fraction on both continents. The "normal" prices in Europe aren't reflective of the cost of the fossil fuel itself. In point of fact, countries in Europe often have lower tax rates on diesel, despite being generally worse for the environment.
Americans drive larger vehicles because our politicians stupidly decided mandating fuel economy standards was better than a carbon tax. The standards are much laxer for larger vehicles. As a result, our vehicles are huge.
Also, Americans have to drive much further distances than Europeans, both in and between cities. Thus gas prices that would be cheap to you are expensive to them.
Things are the way they are because basic geography, population density, and automotive industry captured regulatory and zoning interests. You really can't blame the average American for this; they're merely responding to perverse incentives.
How is this in any way relevant to what I said? You're just making excuses, but that doesn't change the fact that americans don't give a fuck about the climate, and they objectively pollute far more than those in normal countries.
If you can't see how what I said was relevant, perhaps you should work on your reading comprehension. At least half of Americans do care about the climate and the other half would gladly buy small trucks (for example) if those were available.
It's lazy to dunk on America as a whole, go look at the list of countries that have met their climate commitments and you'll see it's a pretty small list. Germany reopening coal production was not on my bingo card.
