Congressman Tom Reed, a rare Republican member of the US House of Representatives who openly advocates for taking steps to mitigate climate change, has warned the renewables industry that the preservation of the phase-out of their key tax credits is “not a done deal” as Congress tackles tax reform.

The US renewables sector breathed a tremendous sigh of relief in January when, during his confirmation hearing, now-Treasury Secretary Steven Mnuchin indicated he supported the scheduled phase-out of the wind production tax credit (PTC) in an exchange with Republican Senator Charles Grassley of Iowa, who is an outspoken supporter of the wind industry.
