TRUMP: And we are putting up wind. It does not work, aside from ruining our fields and valleys and killing all the birds. Being very weak and expensive, all made in China. I have never seen a wind farm in China. Why is that?

The assertion that wind power 'does not work' is contradicted by extensive evidence showing wind energy as a viable and growing source of renewable electricity worldwide. While there are some environmental concerns such as bird mortality and local impacts, these are generally considered manageable and do not negate the effectiveness of wind power. The New York Times fact-check highlights that claims about wind farms ruining property values or being ineffective are dubious.

Regarding cost and strength, wind energy costs have decreased significantly over the years, making it competitive with or cheaper than fossil fuels in many regions. The characterization of wind as 'very weak and expensive' ignores these economic trends and the substantial contribution of wind to energy grids.

The claim that all wind turbines are made in China is inaccurate. While China is a major manufacturer of wind turbines and components, many countries including the U.S., Germany, Denmark, and others produce turbines domestically or import from various suppliers. The global wind industry is diversified.

The statement about never seeing a wind farm in China is misleading because China has the world's largest installed capacity of wind power, with numerous onshore and offshore wind farms across the country. This fact contradicts Trump's personal claim.
