In the first half of 2024, the US significantly boosted its electricity production from utility-scale solar energy, with an increase of nearly one-third compared to the same period in 2023.
Despite this increase, the potential environmental gains were offset by a sharp increase in overall electricity demand – much of which was met by an increase in fossil-fuel generated energy, too.
Published this week, the Energy Information Administration (EIA)’s electricity generation statistics for June provided a detailed snapshot of the energy landscape halfway through 2024. Though the data demonstrate’s the nation’s move toward renewable energy adoption, it suggests that this might be slower than needed.
Electricity Usage: First Half of 2024
In the US, electricity generation from utility-scale power plants reached 2.1 million gigawatt-hours between January and June – a 5% increase compared to the first half of 2023. This represents the largest percentage growth in decades when comparing the first half of one year to the same period the previous year.
Experts in grid planning have cautioned that the US is entering a period of rapid growth in electricity consumption, driven by the needs of data centers, factories, and other new developments.
Another significant factor contributing to this year’s energy consumption is the extreme heat, including what was the second-hottest June on record.
Dependency on Carbon-Free Sources
The rapid rise in electricity demand poses challenges for those addressing climate change, as it expands the amount of energy that new, carbon-free sources must cover and weakens the economic argument for retiring fossil fuel power plants.
Nevertheless, carbon-free energy sources made considerable gains in the first half of 2024.
Utility-scale solar power plants produced 102,615 gigawatt-hours, a 30 percent increase from the first half of 2023. Wind energy, both onshore and offshore, contributed 247,434 gigawatt-hours, an 8 percent increase.
Fossil fuel generation also grew. Natural gas plants, which dominate the US electricity mix, generated 857,023 gigawatt-hours, a 5 percent rise. Coal-fired plants added 303,027 gigawatt-hours, a 1 percent increase.
In simpler terms, natural gas and coal production increased by a combined 46,843 gigawatt-hours, while wind and solar combined for a rise of 42,698 gigawatt-hours.
Though this may seem discouraging, it’s worth noting that the total increase from carbon-free sources, including nuclear, wind, and solar, was 51,711 gigawatt-hours, surpassing the combined increase in fossil fuel generation.
The larger issue remains: the growth of carbon-free energy needs to outstrip fossil fuel generation by a much larger margin, and it isn’t yet happening.
New Power Plants
So far in 2024, the US has seen a substantial shift towards renewable energy in new power plant construction. Of the 375 new generating units that came online between January and July, 243 were utility-scale solar farms, and 75 were utility-scale battery systems, often paired with renewable energy. Seventeen were onshore wind farms, and one was an offshore wind farm—South Fork Wind off the coast of New York.
During the same period, 38 units burning natural gas or petroleum began operating, along with one new nuclear unit at the Vogtle plant in Georgia. No new coal plants were built.
The new installations have a combined capacity of 23,326 megawatts, with 76 percent of this total coming from solar and battery systems, and 95 percent from carbon-free sources such as solar, wind, and nuclear.
While it’s encouraging to see carbon-free sources dominating new construction, it’s essential to remain cautious. To make a meaningful dent in carbon emissions, solar, wind, and battery installations need to not just lead in new capacity but do so by a massive and sustained margin over many years. Simultaneously, fossil fuel-based electricity generation must see a long-term, substantial decline.
