The billionaire businessman’s stake in Nextera Energy has been made public as he bids to become the next US President.
The tycoon, worth around £6.5 billion whose mother was from the Isle of Lewis, is famed for being an outspoken critic of wind energy.
He became embroiled in a bitter legal battle against an offshore wind farm near his Aberdeenshire golf resort.
And just last month he claimed former First Minister Alex Salmond was bent on destroying some of the great beauty of the world by backing wind power.
The revelation came to light in a financial disclosure to the Federal Election Commission. Included in the 69-year-old’s 90-page list was the admission he holds shares ranging from $50,000 (£32,200) to $100,000 (£64,400) in Nextera Energy.
The firm – based in Florida – claims to be one of the world’s largest generators of wind power.
A spokesman for Mr Trump defended the billionaire’s investments: “The report clearly states that Deutsche Asset & Wealth Management A/C 1 Brokerage Acct Holdings manages a portion of Mr Trump’s money and independently makes investments on his behalf.
“These types of investments and the specific stocks chosen by Deutsche are done without Mr Trump’s knowledge or involvement.”
Commenting on the declaration, Scottish Green Party co-convener Patrick Harvie said: “I’m not at all surprised.”
