Renewables overtake coal in the reshaping of American electricity

Renewables overtake coal in the reshaping of American electricity

Built World
By Newzino Staff |

After a century as the backbone of the U.S. power grid, coal has been eclipsed by wind, solar, and hydro — and the gap is widening fast

October 16th, 2023: EIA reports renewables firmly ahead of coal in U.S. generation

Overview

For most of modern American history, coal generated the majority of the nation's electricity — roughly half of every kilowatt-hour consumed from the 1950s through the 2000s. In 2022, renewable sources surpassed coal-fired generation on an annual basis for the first time. By 2023, renewables produced about 22% of U.S. electricity while coal had fallen to 16%, a gap that is accelerating year over year.

Why it matters

The fuel that powered American electricity for a century now generates less than wind, solar, and hydro combined — and the shift is permanent.

Timeline

  1. EIA reports renewables firmly ahead of coal in U.S. generation

    Analysis

    The Energy Information Administration publishes updated analysis showing renewables generating about 22% of U.S. electricity compared to coal's 16%, with the gap widening as coal retirements accelerate.

  2. Renewables begin 121-day streak outpacing coal

    Milestone

    Renewables surpass coal in daily generation and maintain the lead for 121 consecutive days through June 4, demonstrating the durability of the crossover.

  3. Renewables surpass coal on an annual basis for the first time

    Milestone

    For full-year 2022, renewable sources generate more electricity than coal in the U.S. electric power sector for the first time ever. Coal's share falls to 20%; renewables reach 21%.

  4. Inflation Reduction Act signed into law

    Policy

    President Biden signs the largest U.S. climate investment in history, allocating $369 billion for energy and climate programs including 10-year extensions of solar and wind tax credits.

  5. Renewables briefly surpass coal in monthly generation

    Milestone

    In April 2019, U.S. electricity generation from renewables exceeds coal for the first time in a single month, driven by strong spring hydro and wind output.

  6. Natural gas overtakes coal as top U.S. electricity fuel

    Milestone

    For the first time on an annual basis, natural gas generates more U.S. electricity than coal, ending coal's decades-long reign as the dominant fuel.

  7. Coal generation drops 21% in a single quarter

    Market Shift

    In the first quarter of 2012, coal-fired generation falls sharply as cheap natural gas floods the market, accelerating plant retirements.

  8. U.S. coal-fired generating capacity peaks at 318 gigawatts

    Milestone

    Coal capacity reaches its all-time high. From this point forward, retirements consistently outpace new builds.

  9. Shale gas boom begins reshaping the fuel mix

    Market Shift

    Hydraulic fracturing and horizontal drilling unlock vast natural gas reserves, crashing gas prices and making gas-fired plants cheaper to run than coal.

  10. Coal generation peaks at 2.02 billion megawatt-hours

    Milestone

    Coal-fired power plants generate about 49% of all U.S. electricity, the highest absolute output the fuel will ever reach. Coal consumption hits 1.128 billion short tons.

Scenarios

1

Coal falls below 10% of U.S. electricity by 2030

Discussed by: Institute for Energy Economics and Financial Analysis (IEEFA), Ember, EIA Short-Term Energy Outlook

With over 80 gigawatts of coal capacity scheduled for retirement through 2030 and no new coal plants under construction, coal's share continues its steep decline. Cheap natural gas and rapidly expanding solar and wind — accelerated by Inflation Reduction Act incentives — capture the freed-up demand. Under this scenario, coal becomes a marginal fuel used primarily for grid reliability during extreme weather peaks.

2

Renewables reach 40% of U.S. electricity by 2030

Discussed by: Solar Energy Industries Association (SEIA), American Clean Power Association, Department of Energy projections

The Inflation Reduction Act's 10-year tax credit extensions trigger a sustained build-out of solar and wind capacity, with solar alone projected to add 160 gigawatts over the decade. Battery storage solves intermittency for an increasing share of demand. This scenario requires continued permitting reform, transmission expansion, and supply chain stability — all of which face political and logistical headwinds.

3

Coal stabilizes near current levels as data centers spike demand

Discussed by: Grid operators (PJM, MISO), coal industry groups, energy analysts covering AI-driven electricity demand

A surge in electricity demand from data centers, artificial intelligence computing, and re-shoring of manufacturing outstrips new renewable capacity additions. Grid operators extend the life of coal plants to maintain reliability, and political pressure in coal-dependent states slows retirements. Coal doesn't recover market share but its absolute generation stabilizes rather than continuing to fall.

4

Policy reversal slows renewable growth, extends coal lifelines

Discussed by: Congressional Research Service, energy policy analysts, utility industry publications

A future administration or Congress rolls back Inflation Reduction Act incentives, tightens permitting for wind and solar, or actively subsidizes coal to preserve jobs in producing states. Renewable capacity additions slow while existing coal plants receive regulatory extensions. The crossover still holds — coal doesn't regain dominance — but the gap narrows rather than widens.

Historical Context

United Kingdom closes its last coal power plant (2024)

September 2024

What Happened

The Ratcliffe-on-Soar power station in Nottinghamshire shut down, making the United Kingdom the first major economy to fully exit coal power. Britain had been burning coal for electricity for nearly 150 years. At its peak in the 1980s, coal generated roughly 70% of British electricity.

Outcome

Short Term

The UK eliminated coal from its grid without reliability disruptions, relying on a mix of natural gas, wind, and nuclear to fill the gap.

Long Term

The UK's coal exit became a reference case for other industrialized nations, demonstrating that a wealthy economy can retire its entire coal fleet within a generation.

Why It's Relevant Today

The U.S. is on a similar trajectory but roughly a decade behind. The UK example shows what full coal exit looks like in practice and suggests the U.S. shift is unlikely to reverse, even though America's larger and more geographically diverse grid makes the timeline longer.

Natural gas overtakes coal as top U.S. fuel (2016)

2016

What Happened

Natural gas surpassed coal as the largest single source of U.S. electricity generation for the first time, driven by a decade of plummeting gas prices from the shale revolution. The shift happened without any government mandate — market economics alone made gas cheaper to burn than coal in most regions.

Outcome

Short Term

Coal plant retirements accelerated as utilities found it uneconomic to maintain aging coal plants against cheap gas competition.

Long Term

The gas-for-coal substitution cut U.S. power-sector carbon emissions significantly, even as total electricity demand held roughly steady. It also established the precedent that fuel transitions can happen quickly when economics align.

Why It's Relevant Today

The 2016 gas-coal crossover set the stage for the renewable-coal crossover. Coal didn't lose to renewables directly — it first lost to gas, which shrank coal's share enough that renewables could leapfrog it. Understanding this two-step displacement is essential to grasping why coal's decline has been so rapid.

Germany's coal phase-out debate (2018–present)

2018–present

What Happened

Germany convened a coal commission in 2018 and legislated a coal phase-out by 2038, later accelerated to 2030 in some proposals. Despite strong renewable growth, Germany struggled with the transition because it simultaneously decided to close its nuclear plants, temporarily increasing reliance on coal during the 2022 European energy crisis.

Outcome

Short Term

Germany briefly reopened mothballed coal plants in 2022 when Russian gas supplies were cut, highlighting the risks of retiring baseload capacity too quickly.

Long Term

Coal-fired electricity in Germany fell by nearly two-thirds from 2014 to 2024, but the path was rockier than the UK's, demonstrating that energy transitions depend heavily on what replaces coal, not just the decision to close plants.

Why It's Relevant Today

Germany's experience illustrates the tension the U.S. faces: retiring coal is straightforward when cheap gas and growing renewables fill the gap, but demand surges or supply disruptions can complicate the timeline. The U.S. benefits from abundant domestic gas, which Germany lacks.
