In-brief analysis

June 4, 2025

U.S. production of renewable diesel and biodiesel fell sharply in the first quarter of 2025 (1Q25) because of uncertainty related to federal biofuel tax credits and negative profit margins. We forecast production of both fuels to increase as the year progresses but biodiesel production to remain less than in 2024.

Renewable diesel and biodiesel are biomass-based diesel fuels that can replace petroleum-based distillate and be used to comply with renewable volume obligations in the Renewable Fuel Standard (RFS) administered by the U.S. Environmental Protection Agency (EPA). Renewable diesel can be used in diesel engines in any concentration because it is chemically equivalent to petroleum-based distillate fuel, and biodiesel is typically blended with petroleum distillate at concentrations of 20% or less for vehicle consumption because of some chemical differences.

In January 2025,

Note: L48=U.S. Lower 48 states

Onshore crude oil production in the U.S. Lower 48 states (L48) has more than tripled since January 2010, driven by tight oil production growth in the Permian region. Onshore crude oil production is made up of both legacy oil production, primarily from vertically drilled wells, and newer tight oil production, primarily from horizontally drilled wells.

Legacy production decreased from 2.6 million barrels per day (b/d) in 2010 to 2.1 million b/d in 2024. Over the same period, tight oil production increased from 0.8 million b/d to 8.9 million b/d, accounting for 81% of total onshore L48 oil production in 2024. The Permian accounted for 65% of all

Data source: Wards Intelligence

About 22% of light-duty vehicles sold in the first quarter of the year in the United States were hybrid, battery electric, or plug-in hybrid vehicles, up from about 18% in the first quarter of 2024. Among those categories, hybrid electric vehicles have continued to gain market share while battery electric vehicles and plug-in hybrid vehicles have remained relatively flat, according to estimates from Wards Intelligence.

These different vehicle types affect the broader energy sector in different ways. Battery electric vehicles and plug-in hybrid vehicles can consume electricity from isolated power sources or, more commonly, from the grid. So, their use can affect electricity demand. By comparison, hybrid electric vehicles do not have plugs, so they don’t directly affect grid-delivered electricity demand.

May 28, 2025

The California Independent System Operator (CAISO), the grid operator for most of the state, is increasingly curtailing solar- and wind-powered electricity generation as it balances supply and demand amidst rapid renewables capacity growth.

Grid operators must balance supply and demand to maintain a stable electric system. The output of wind and solar generators is reduced either through price signals or, rarely, through an order to reduce output during periods of:

Congestion, when power lines don’t have enough capacity to deliver available energy Oversupply, when generation exceeds customer electricity demand

In 2024, CAISO curtailed 3.4 million megawatthours (MWh) of utility-scale wind and solar output, a 29% increase from the amount of electricity curtailed in 2023.

Solar accounted for 93% of all the energy curtailed in CAISO in 2024. CAISO curtailed the
