Plans by Honda to build Wiltshire's first wind turbines have been rejected.
The car company had proposed three wind turbines to power its plant near South Marston in partnership with energy supplier Ecotricity.
Planning officers had recommended Swindon borough councillors approved the plans.
However, councillors voted against the application by nine votes to three abstentions. Honda said it would now consider whether to appeal.
Residents said the 394ft (120m) high turbines would be be too large and noisy.
'Inappropriate at this time'
South Marston-based protest group Ill Wind said even though Honda had suggested scaling back the plans to two turbines they remained too close to homes at a distance of 1,935ft (590m).
Andy West, from the group, said: "It's absolutely fantastic. We don't want these turbines in Swindon because they're totally unsuitable."
Councillor Dale Heenan said the committee had been "between a rock and a hard place" when making the decision.
"On the one side, as councillors, we're here to represent residents and on the other side of the argument the applicant is one of the biggest employers in the town.
"On balance the committee decided the application for the three wind turbines was inappropriate at this time."
Honda had argued it was essential to keep its Swindon car and engine manufacturing site one of the world's most efficient while also meeting internal targets to reduce its carbon footprint.
In a statement it said: "We are obviously very disappointed with the decision, however, we will be discussing our options with Ecotricity over the next few days."
