For years, the argument over climate change has often been framed as a choice.
Protect the environment or protect the economy.
Denmark provides an interesting challenge to that assumption.
Denmark has spent decades building an economy around cleaner energy while maintaining a highly developed capitalist economy.
Wind now produces nearly half of Danish electricity. Denmark was also the first country in the world to build an offshore wind farm.
And Denmark isn't stopping there.
In 2020, a broad parliamentary majority agreed to end oil and gas extraction in the Danish North Sea by 2050 and cancel future licensing rounds.
That doesn't mean Denmark has already eliminated fossil fuels.
Far from it.
Denmark still produces oil and gas. The transition is exactly that — a transition.
But look at what is happening elsewhere in the economy.
Electric vehicles represented 80.2% of all new passenger cars registered in Denmark in July 2026. Among private buyers, the percentage reached 97%.
Denmark has used public policy to change the economics of buying a car. Tax advantages for electric vehicles have been an important part of that transition.
That brings me back to the United States.
Why haven't we moved as decisively?
One answer is political influence.
There is substantial evidence that the fossil-fuel industry has worked to influence American climate policy.
A peer-reviewed 2024 study examining the failure of federal cap-and-trade legislation found a significant relationship between fossil-fuel lobbying and campaign contributions and congressional access given to people challenging the scientific consensus on climate change.
Another study published in 2025 examined federal lobbying surrounding carbon capture and related technologies. It estimated that fossil-fuel interests spent approximately $954 million lobbying the federal government on those issues between 2005 and 2024.
But stopping there would make the explanation too easy.
The fossil-fuel industry does not single-handedly explain why the United States has followed a different path.
The United States is vastly larger than Denmark. We have different geography, different infrastructure, enormous domestic fossil-fuel resources, 50 state governments and a very different political system.
There is another complication.
The line separating traditional energy companies from renewable-energy companies is becoming less clear. Research examining Texas found that traditional energy companies sometimes supported renewable-energy policies when those policies also benefited their renewable investments.
Perhaps, then, this isn't simply a story about renewable energy fighting fossil fuels.
It is a story about incentives.
Denmark made a series of long-term policy decisions that changed those incentives.
Businesses responded.
Consumers responded.
Capital responded.
That may be the lesson worth taking from Denmark.
The green transition doesn't necessarily have to be an economic sacrifice.
Done well, it can become an economic strategy.
The Parting Glass
Perhaps Denmark's most interesting accomplishment isn't how many wind turbines it has built or how many electric vehicles its citizens buy.
It is that Denmark has spent decades changing the economics surrounding those decisions.
That distinction matters.
If cleaner technologies depend indefinitely upon people voluntarily paying more or accepting less, widespread adoption will always be difficult.
But change the economics, and behavior can change with it.
The United States faces circumstances that are very different from Denmark's, and copying Danish policy wholesale would make little sense.
But we can still ask what Denmark's experience teaches us.
Instead of asking whether environmental protection or economic growth should win, perhaps we should be asking a different question:
How do we structure the economics so they can win together?
