That part entirely true and easily verified.
Fact-checking Donald Trump's claim that wind turbines kill whales
There is no evidence to back Mr Trump's suggestion that offshore wind turbines are killing whales.
NOAA officials carried out post-mortem examinations on about 90 humpback whales found dead since 2016.
Forty per cent of those deaths
were linked to human interaction - whales becoming entangled in fishing nets, or being struck by vessels travelling through their feeding grounds.
In the remaining cases investigated by NOAA, other factors were listed as possible causes of death, including parasite-caused organ damage or starvation.
In some cases, the advanced stage of decomposition of the carcasses meant it was impossible to conclusively determine the cause of death.
"We know what the main threats are to humpback whales: it's very much the impact from things like fishing and ship strikes," says Rob Deaville from the Zoological Society of London's Cetacean Strandings Investigation Programme.
"To talk about wind farms being a problem takes away discussion around the very real threats that are a problem for those species."
Many other areas with high numbers of wind farms have not seen an increase in whale mortality.
For example, the UK is home to the world's four largest wind farms, but no humpback whale strandings there have been conclusively linked to the impact of those farms.
While it is true windmills kill birds that is dwarfed by the kill rate caused by the pollution of coal plants
