Why Trump's cabinet won't derail renewables' growth
As Donald Trump's cabinet nominees have their confirmation hearings, global clean energy market momentum shows no signs of stopping.
When he nominated Oklahoma Attorney General Scott Pruitt as EPA director, former Texas Gov. Rick Perry as energy secretary and Exxon CEO Rex Tillerson as secretary of state, many perceived that Donald Trump put down his marker for fossil fuels and against renewables.
Yet in their confirmation hearings, they went out of their way to distance themselves from that notion. Tillerson was upbeat about the U.S. stepping up on renewables. Pruitt said climate change was not a hoax and indicated general support for renewables. Perry disavowed his position in the 2012 election that the Department of Energy should be abolished, and cast doubt on reports the Trump administration intended to defund the Department of Energy office of Renewable Energy and Efficiency.
So where does that leave us? Should we be bearish on the near-term future of clean energy? Hardly. Of the many forces influencing it, national politics is not one of the stronger ones. The Trump administration may have little interest in decarbonization, but markets have a great deal of interest in it. Based on the signals it has sent so far, the administration seems to have little incentive or appetite for getting in the way.
Global renewables investment is enormous — China alone invested $100 billion last year. In many countries, solar and wind are reaching cost parity with fossil fuels. We’re rapidly surging toward a multi-trillion-dollar global clean energy market — the largest in history.
In the U.S., renewables generate more energy than in any other country except China. They are about 15 percent of our domestic energy mix and ramping up fast. Since 2008, U.S. wind power tripled, while solar increased thirtyfold. Domestic demand for renewable energy is skyrocketing, and the number of tariff programs to deliver it to large corporate customers, such as Facebook’s new data center in New Mexico, doubled in 2016.
Many U.S. states and cities are reaffirming and progressing toward ambitious decarbonization goals. Half of U.S. renewable generation investments in the last five years exceeded state requirements under Renewable Portfolio Standards. Those investments owe nothing to policy incentives, and yet cut carbon emissions by 100 million tons annually, or about 5 percent of the U.S. electricity sector’s total emissions.
Beyond solar and wind, new, promising renewable energy markets are emerging, such as renewable natural gas. RNG is nearly identical to geologic natural gas. It burns as cleanly, and can be transported in the same pipelines and burned in the same power plants, boilers and vehicles. But it’s not a fossil fuel. It’s made from biogas emitted by decomposing organic materials such as farm waste, food waste and municipal wastewater, which are renewable, ubiquitous resources.
Capturing and refining that biogas turns what otherwise would be greenhouse gas pollution into clean energy for heat, electricity or transportation. As a transportation fuel, over its lifecycle RNG can be net carbon-negative, meaning it actually results in less atmospheric greenhouse gas than if the organic wastes were just left to rot and outgas. The more RNG we make and use to displace diesel and gasoline, the lower net emissions go.
Electrification currently can't deliver the energy density that 18-wheelers need, but RNG can. And while they are only 4 percent of all U.S. vehicles, heavy-duty buses and trucks represent a quarter of domestic road fuel use and a quarter of transportation’s greenhouse gases. Running them on RNG slashes those emissions deeply.
RNG already fuels UPS delivery vehicles, Santa Monica’s entire Big Blue Bus fleet, and soon it will power the world’s largest natural gas vehicle fleet, L.A. County Metro. Last year, almost 20 percent of natural gas used in transportation was waste-derived RNG, including over 50 percent in California. Production is rising fast. Measured in terms of how much diesel or gasoline it displaces, domestic RNG production went from 20 million gallons in 2013 to nearly 150 million gallons last year.
That’s remarkable growth, but it still isn’t easy for emerging renewables such as RNG to scale up in energy markets heavily dominated by fossil fuels. They can benefit enormously from market-based policy incentives such as EPA’s Renewable Fuel Standard, which includes tradable credits for RNG producers. It has helped drive the recent surge in RNG use as a transportation fuel, and new investment and job creation in the RNG sector.
Would the Trump administration end such incentives? It seems unlikely. When Ted Cruz called for the RFS to be repealed, candidate Trump defended it. Pruitt in his confirmation hearing this week expressed general support for EPA's RFS program. That's a shift away from his statements as Oklahoma Attorney General, which were critical of the RFS. But as an Oklahoma legislator, he also supported alternative energy development, including biomass. For that matter, as Texas governor, Perry presided over a massive expansion of wind power. And as Exxon CEO, Tillerson repeatedly affirmed support for a carbon tax.
While we don't yet know the new administration’s renewables policy, we do know jobs are a top Trump priority. 2.5 million Americans and counting work in the renewables and energy efficiency sectors. Hundreds of thousands of non-exportable jobs in "red" states come from production of domestic, non-petroleum fuel. There are more U.S. solar jobs than oil/gas/coal extraction jobs, and solar jobs are growing 12 times faster than overall job creation. Would Trump and colleagues want to undermine that kind of growth for political reasons?
Whether they do or don’t, as they’d say in Texas or Oklahoma, the horse is out of the barn. Progress on renewables is picking up speed and the market momentum behind them is strong. They still need policy incentives and all the impetus clean energy advocates can give them. But they will continue to make progress — and money — regardless of who makes or executes energy policy in Washington.
