But they’re less secure in a Republican administration than a Democratic one (although they did survive last year’s tax bill mostly unscathed).And I think it’s accurate to say that U.S. policy on renewables since the 1970s has been marked more by ambivalence than anything else.Which makes a certain amount of sense: Renewables are competitors to fossil fuels.The U.S. leads the global fossil fuels industry. It can be tough to dominate both an incumbent industry and the one that aims to disrupt it.That doesn’t mean it isn’t worth trying, though.Justin Fox, a Bloomberg View columnist, was the editorial director of Harvard Business Review. The wind industry is headquartered in Europe, and the solar industry increasingly in China.Last week, as I’m sure you have heard, the Donald Trump administration slapped a 30 percent tariff on imports of certain solar cells that the U.S. International Trade Commission found last fall to be an unfairly priced threat to U.S. manufacturers.Most media coverage of the decision has focused on the effect on the U.S. solar power industry, which is up in arms about a move that will raise its costs. Fair enough.But wouldn’t it also be a good thing for the U.S. to have a bigger solar-cell manufacturing industry?There are several reasons why it might be.The most discussed but probably least compelling one is that it would create factory jobs.Installing and maintaining solar and wind power equipment employs a lot more people than making it, and the Bureau of Labor Statistics projected last year that the two occupations with the fastest projected job growth in the U.S. over the next decade will be solar photovoltaic installers and wind turbine service technicians.

If jobs are the metric, then keeping solar panels cheap seems more important than having them made here.A better argument that Harvard Business School’s Gary Pisano has been making for almost a decade now is that manufacturing capabilities underpin innovation and economic growth.Let them go overseas, and much more is lost than just production jobs.In 2012, Matthew Stepp and Robert Atkinson of the Information Technology and Innovation Foundation, a bipartisan Washington think tank, argued that China’s use of subsidies, trade restrictions, currency manipulation and theft of intellectual property to give homegrown solar and wind equipment makers a leg up was hurting energy innovation not just in the U.S. but also worldwide.The best approach for the U.S. going forward, Atkinson says, is to look beyond current technologies.“The game should be, What’s the next transformative technology in solar? How could we be the world leader?”That’s easier to ask than answer, of course. Categories: Editorial, OpinionThe oil industry was born in Pennsylvania in 1859, and Americans have played a leading role in it ever since.Even after the U.S. lost its status as the world’s top oil producer in the 1970s, it remained the industry’s main source of equipment and expertise.In recent years, U.S. technology and entrepreneurship have even brought a production resurgence that has made this country again the world’s biggest source of petroleum and natural gas hydrocarbons and may soon even catapult it back into first place in crude oil production.In renewable energy, things have played out a bit differently. The U.S. does still seem to be fertile ground for starting innovative energy companies.As in the oil and gas industry, U.S. technological know-how and business dynamism can be an advantage.But it’s worth thinking about what else has enabled the U.S. oil and gas industry to play such a durable global leadership role.One obvious asset has been the presence of huge amounts of oil and natural gas under the ground and nearby ocean floor.Another has been more than a century of mostly supportive government policy.This support has taken the form of not just legal advantages (most mineral rights in the U.S. are privately owned, not government property as in other countries) and tax breaks (which go back at least to the Revenue Act of 1916), but also huge military expenditures to protect the interests of U.S. oil companies overseas.Since 2005, the tax preferences for renewable fuels have been bigger than those for oil and gas.
