Ministers recently approved the plan to build 11-turbines right next to Trump's massive golf resort in Aberdeenshire. He fears it will ruin the ocean views.
Fergus Ewing, energy minister, approved the plan for the European Offshore Wind Deployment Center to build the wind farm. It is predicted to produce up to 100MW of power, which is roughly equal to half of the homes in Aberdeen.
When Trump heard of the news, he wrote, "The Scottish wind farm was conceived by the same mind that released terrorist al-Megrahi."
He said he would spend "whatever is necessary" to block the plan, adding, "this was a purely political decision, as dictated by Alex Salmond, a man whose obsession with obsolete wind technology will destroy the magnificence and beauty of Scotland."
"Likewise, tourism, Scotland's biggest industry, will be ruined."
Trump does not understand why they are adamant on building the wind farm, as "all over the world they are being abandoned."
He plans to file a lawsuit to stop it as well.
The government said that the farm will be built 1.28-2.8 miles off the coast.
The plan was created by Vattenfall Wind Power and Aberdeen Renewable Energy Group.
"Offshore renewables represent a huge opportunity for Scotland, an opportunity to build up new industries and to deliver on our ambitious renewable energy and carbon reduction targets," Ewing said.
Ewing believes it could generate around £7 billion for the economy and employ 28,000 people.
"The North-East of Scotland is a world energy capital and, in order to continue to prosper, we have to be at the forefront of all forms of energy research - marine renewables, as well as oil and gas."
But the plan has to have one more approval by the Aberdeenshire Council before it can be built. A hearing was deferred yesterday on a decision.
