August 5, 2026 – The Low-Carbon Energy Data Service has published its latest comprehensive dataset, covering historical and forward-looking levelized cost of energy (LCOE), electric vehicle sales, the definitive Green Utilities ranking, fuel switching thresholds, electricity production by sector, ethanol and biodiesel fundamentals, and carbon pricing. This release provides a critical snapshot of the accelerating energy transition, with several metrics showing inflection points that analysts say could reshape investment strategies.
The latest LCOE calculations reveal that utility-scale solar photovoltaic (PV) has reached an average of $28 per megawatt-hour (MWh), down 12% from the previous year, while onshore wind stands at $32/MWh. In contrast, combined-cycle natural gas remains at $45–$55/MWh when including carbon costs. “The cost crossover is now permanent in most US markets,” said Dr. Elena Martinez, energy economist at the Rocky Mountain Institute. “Future LCOE projections through 2030 show solar dipping below $20/MWh, which will render new gas plants uneconomic without significant subsidies.” The data service also includes updated methodology that accounts for grid integration costs, a factor often omitted in simpler comparisons.
Electric vehicle sales in the United States reached 1.8 million units in the second quarter of 2026, representing 25.3% of all new light-duty vehicle registrations. This marks a 40% year-over-year increase and places the country on track to meet the Biden administration’s target of 50% EV share by 2030. The data highlights a shift in consumer preference: battery electric vehicles (BEVs) now account for 18% of sales, while plug-in hybrids (PHEVs) make up 7.3%. Key drivers include the expansion of Tesla’s Supercharger network to non-Tesla vehicles and the rollout of $7,500 federal tax credits for domestically assembled models. The EV sales database now includes granular state-level breakdowns, with California leading at 42% and Texas surging to 19%.
The 2026 Green Utilities ranking evaluates 50 largest US electric utilities based on renewable energy mix, carbon reduction targets, and grid modernization. For the first time, a cooperative utility—the Tennessee Valley Authority (TVA)—entered the top 10, driven by its 2.5 GW solar procurement and early retirement of coal units. The top three spots remain held by NextEra Energy, Pacific Gas and Electric, and Southern Company, each achieving over 60% carbon-free generation. However, the data service warns that the ranking methodology now includes a “community benefit” score, weighting equity in renewable siting, which has caused some utilities to drop in rank. This adjustment reflects broader regulatory trends, particularly in states like Illinois and New York.
The fuel switching thresholds dataset has been updated to reflect the economics of converting natural gas heating to electric heat pumps. The analysis shows that in regions with electricity prices below $0.12/kWh and heat pump efficiency of 300%, the payback period is now less than three years for households replacing furnaces older than 15 years. The data service provides a state-by-state calculator, updated with 2026 utility rates and federal rebates under the Inflation Reduction Act. “For the first time, switching is cost-effective even in cold climates like Minnesota, thanks to cold-climate heat pump technology,” noted the service’s lead analyst.
Electricity production by sector data reveals that renewable sources (wind, solar, hydro, biomass, geothermal) accounted for 48.7% of US generation in the first half of 2026, up from 44% in the same period of 2025. Solar alone grew 22% year-over-year, while coal fell to 14% of the mix. The data service attributes this leap to a record 35 GW of new solar capacity installed in 2025, coupled with the retirement of 8 GW of coal-fired power. The forward-looking model projects renewables reaching 55% by 2028, contingent on transmission buildout in the Midwest and Southwest.
The ethanol and biodiesel fundamentals dataset includes 2026 production volumes, feedstock prices, and policy impacts. Ethanol production is averaging 1.05 million barrels per day, supported by strong demand for E15 blends. However, the data highlights a growing divergence: biodiesel and renewable diesel production has surged to 200,000 barrels per day, driven by California’s Low Carbon Fuel Standard (LCFS) credits and the federal Renewable Fuel Standard (RFS). The cost of soybean oil, a primary feedstock, has risen 15% in 2026, squeezing margins. The data service now includes a “carbon intensity” score for each pathway, enabling investors to compare lifecycle emissions.
Carbon pricing data shows that the average price in the Regional Greenhouse Gas Initiative (RGGI) rose to $18.50 per short ton in the latest auction, while California’s cap-and-trade program reached $38.70 per metric ton. The data service has expanded its coverage to include the newly launched Washington state carbon market, where allowances traded at $42.00 in July. Analysts point to the recent Supreme Court ruling upholding California’s
