The Financial Times/Harris Poll found 87% of US adults surveyed are in favour of more wind farms in their country, compared to 90% in Spain and 77% in France.
But a majority in all countries said they would either pay no more or only 5% more for renewable energy.
The proportion willing to pay more varied from 32% in the US and 31% in Italy to only 20% in France and 17% in Spain.
Nuclear power fared worse than wind in the survey. Clear majorities are opposed to building more nuclear power in Italy, Spain and Germany, while the public is fairly equally divided in the US, Britain and France.
The poll was conducted online among 6,255 adults between September 15 and 21.
