Europe not being dependent on foreign oil is a worthy goal as well, it's not the US whcih could supply it's oil use domestically.

A lot of green infrastructure is also expensive upfront, but cheaper over the full lifespan. It's the kind of investment I like to see goverment making.

I think taking care of the environment rather than burning through resources needlessly will improve life for us. But if you're looking for a more specific example, moving to renewable energy and getting off Russian gas and oil would be beneficial in many ways for Europe and at a most basic level would hopefully eventually lead to lower and more predictable energy prices for consumers.
