Although Trump snatched away the solar and wind industry’s beloved tax credits, projects that officially commenced construction by July 4 can still avail themselves of “safe-harbored” tax credits if they wrap up over the next four years. Rhodium expects developers will complete around 50 GW of solar, storage, and wind annually during this time. That outlook holds steady even in the more conservative scenarios, although it’s worth noting the firm’s model might not capture the extent to which the Trump administration’s permitting blockades may thwart development.
Past the bonanza of the late 2020s, those supporting tax credits disappear for wind and solar, and the predictions diverge wildly. The 2030s will come down to a battle for power sector supremacy between renewables-plus-storage and natural gas.
“When you have tax credits, you push up on what’s possible,” Kolus said. “Without them, you let energy markets take over, and then it becomes really a matter of what does clean technology cost and what are natural gas prices — those are the two things that are really driving the divergence in outcomes after 2030.”
In Rhodium’s low-emissions scenario, the low-carbon sources continue to romp, reaching 53 GW of annual installations through 2040 while holding new gas plants to just 5 GW annually. In the high-emissions scenario, the inverted price dynamics elevate gas to 16 GW of annual deployments and suppress clean energy construction to just 3 GW per year. In the middle scenario, renewables fall to an average of 16 GW annually in the first half of the 2030s, then rebound to 45 GW for the second half; annual gas additions meanwhile sit at about 9 GW over the course of the decade.
That high-emissions case would be devastating to the clean energy industry: The plummet from 50 GW of annual construction to 3 GW would decimate the pace of industrial activity, slashing construction jobs, infusions to local tax bases across the country, and new clean power for the states and customers that want it.
Tailwinds for clean energy
Rhodium’s findings square with what I’ve heard while interviewing clean energy professionals: There’s a ton of building to do in the next four years, but anything beyond that is too far off to predict. The energy landscape post-2030 will hinge on who’s in the White House. If that person restores supportive policies, the outlook will shift radically once again.
In the meantime, there are a few reasons to be optimistic that clean energy will avoid the worst-case scenario.
First and foremost, solar, wind, and batteries have a yearslong track record of beating the expert predictions of how cheap they’ll get. Given a range of cost projections, this history would suggest you bet on the low end. That alone could stave off the more dour scenarios described in the report.
Then there’s the changing nature of the U.S. fossil fuel industry. The country has been shipping more and more of its natural gas overseas via liquefied natural gas terminals. So much new export capacity has been approved and entered construction that LNG exports will rise dramatically in any of Rhodium’s scenarios. So far, this growth has had a muted effect on domestic gas prices, because producers have extracted more each year in lockstep with new export demand. But if the industry hit a bust cycle and couldn’t keep pace, basic economics suggests the domestic price would surge as U.S. consumers compete with foreign buyers willing to pay far more. That could weaken the case for gas generation in the 2030s.
Another source of hope for the clean energy contingent is that the modeling may underestimate how fast battery storage will reshape the power sector.
Rhodium notes that storage meaningfully takes off only in its low-emissions case, when lots of new renewables are getting built. But Kolus acknowledged that the analysis focuses on picking the lowest-cost option for new power capacity, whereas developers may build batteries for other reasons. For example, a firm could opt for batteries because they are less polluting than gas combustion turbines, or because they can be built more quickly. Batteries have already appeared in many deals specifically serving demand for data centers, to help tech giants with their climate goals and bring AI computing online faster.
When batteries do arrive in large numbers, they reliably take market share from gas plants. Gas generation in California is plummeting now, because stored solar power is a much cheaper source of nighttime electricity than burning fossil fuels. The broader cleanup of the U.S. power sector, then, will hinge on how quickly other states go the way of California in making batteries a prime source for on-demand energy.
