In his sprawling address to the United Nations General Assembly on Tuesday, President Donald Trump attacked both climate change initiatives and clean energy. He called into question the scientific consensus on the topic and the economic viability of clean energy programs. The speech marks one of his most forceful rejections of climate policy since returning to office.
Trump called climate change “the greatest con job ever perpetrated on the world,” declaring that many predictions by the UN and other international bodies were wrong, made “by stupid people that have cost their country’s fortunes and given those same countries no chance for success.” He derided renewable energy as ineffective, expensive, and a financial drag, calling it a “joke”.
The President zeroed in on Europe and wind turbines in particular, claiming the continent was being “devastated by energy and immigration”. He described windmills as “pathetic and so bad, so expensive to operate” before referring to them as “the most expensive energy ever conceived.”
His rhetoric stood in sharp contrast with international trends and the UN’s broader stance on clean energy. Secretary-General António Guterres, among others, has repeatedly urged nations to accelerate investment in renewables. Meanwhile, wind and solar power are becoming more cost-competitive and are major drivers of new electricity generation worldwide.
Critics say Trump’s claims about renewable energy are misleading. Independent fact-checkers note that while renewable energy infrastructure does require upfront capital, long-term costs have been declining, and many regions have already seen meaningful returns and emissions reductions. They also point out that calling climate science predictions “stupid” and describing green energy as a conspiracy ignores the mounting empirical evidence of climate change and its impacts.
From an oil and fossil fuel perspective, Trump’s speech underscores a clear policy orientation: to re-prioritize traditional sources such as oil, gas, coal, and even nuclear power over clean energy.
Clean energy stocks and ETFs traded lower following the speech, reflecting concern about regulatory and policy headwinds. For countries leaning heavily toward green energy, the warning from the U.S. may add political uncertainty, especially in sectors where technology, subsidies, and regulatory support are key.
The energy market observers, this latest speech confirms the Trump administration’s commitment to put traditional energy at the center of its energy policy. For clean energy proponents, the message is a clear and concerning one.
