The US solar industry's new growth region: Trump country

By Nichola Groom

LOS ANGELES, Oct 12 (Reuters) - President Donald Trump's administration has vowed to revive the coal industry, challenged climate-change science and blasted renewable energy as expensive and dependent on government subsidies.

And yet the solar power industry is booming across Trump country, fueled by falling development costs and those same subsidies, which many Republicans in Congress continue to support.

Data provided to Reuters by GTM Research, a clean energy market information firm, shows that eight of the 10 fastest-growing U.S. solar markets between the second quarters of 2016 and 2017 were Western, Midwestern or Southern states that voted for Trump, with Alabama and Mississippi topping the list. And solar firms are ramping up investments in these regions, signaling their faith that key renewable energy incentives will remain in place for years to come. [GRAPHIC: http://tmsnrt.rs/2ylpJwn ]

The industry's sunny outlook illustrates the complexity of green power politics in Washington and casts doubt on whether the administration can boost the coal and nuclear sectors while subsidies continue to the fuel growth of competing wind and solar.

Solar expansion in the middle of the country is offsetting its slowing growth in the maturing California and Northeast markets. That marks a big shift for an industry that has historically relied on politically liberal coastal states where renewable energy development is mandated to combat air pollution and climate change.

With falling development costs, solar firms now see strong prospects in conservative states with no such mandates.

"Climate change has never come up in any discussion about why we would do a project," said Matt Beasley, chief marketing officer for Silicon Ranch Corp, a solar developer based in Nashville, Tennessee. "It is always about the economics."

The estimated costs of solar power generation have dropped 85 percent since 2009, making its unsubsidized cost competitive with natural gas in the sunniest locations, according to a report by Lazard, an asset management firm.

Still, the sector's growth continues to rely on public support. The U.S. Congress’ Joint Committee on Taxation earlier this year estimated that solar projects would receive $12.3 billion in tax breaks between 2016 and 2020.

Trump has never specifically proposed repealing those incentives but has expressed skepticism about the viability of solar and wind, calling both "very, very expensive".

The president's Energy Secretary Rick Perry last month called for new rules to subsidize coal and nuclear energy, arguing that the rise of weather-dependent solar and wind power would make the grid less reliable.
