The White House on May 17 announced a slate of new programs aimed at integrating US buildings into the clean energy economy. The initiatives include electrification programs for existing homes, workforce training for next-generation jobs in the buildings sector, and efforts to increase the adoption of efficient electric heat pumps and EV fast chargers.
Alongside the plans for job training and building electrification, the announcement also highlighted the Biden administration’s goals for grid-interactive efficient buildings — a less well-known approach that has significant potential to reduce carbon emissions.
In this blog post, we’ll explore what grid-interactive efficient buildings are and why they feature so prominently in plans for a clean energy future.
What Are Grid-Interactive Efficient Buildings?
A grid-interactive efficient building (GEB) continuously optimizes energy use by combining efficiency measures such as LED lighting, efficient heat pumps, and high-performance windows with smart technologies such as solar, battery storage, and integrated building controls. Rather than simply consuming energy from the grid based on the building’s baseline energy use and occupant demands, a GEB interacts with the grid to continuously manage its demand in response to key signals from the electric utility.
To save money, reduce strain on the grid, or limit carbon emissions from electricity generation, a GEB might shed load (e.g., automatically dimming LED lights throughout the building) or shift its load from one time to another (e.g., drawing from on-site batteries rather than the grid) in a practice known as demand flexibility, or load flexibility.
What Is Demand Flexibility?
Demand flexibility is a building’s ability to shed or time-shift its energy demand in response to near-real-time signals about conditions on the grid. Demand flexibility signals can include the current price of electricity, the availability of renewable energy sources such as solar and wind, and the carbon intensity of the current energy mix. For instance, a GEB might employ demand flexibility to shift its peak electricity demand to a time of day when solar energy is abundant and might otherwise be curtailed.
Demand flexibility offers significant promise for reducing the carbon emissions from building operations, especially as the grid integrates more distributed energy resources. But the benefits can extend beyond cost and carbon savings. As detailed in a new RMI insight brief, buildings that flex their demand can shift energy away from peak usage times, when utilities often rely on fossil-burning “peaker” plants to help meet surging demand. Demand flexibility can therefore reduce the need for these peaker plants, eliminating not only their carbon emissions but also their significant contributions to air pollution.
What Are the Potential Benefits of GEBs?
The potential energy, emissions, and cost savings from combining energy efficiency and demand flexibility in GEBs are substantial. Buildings account for more than 70 percent of US electricity consumption and at least one-third of US emissions, according to the US Department of Energy’s Building Technologies Office (BTO). A new GEB roadmap from the BTO estimates that smarter, more efficient buildings can eliminate 80 million tons of CO2 emissions annually by 2030, reducing the emissions of the entire US power sector by 6 percent. The emissions savings from GEBs would be equivalent to retiring more than 50 midsize coal plants or taking 17 million cars off the road.
Widespread adoption of GEB technologies would reduce peak loads on the grid, which would in turn reduce the needed capacity of the grid to meet those demands. The cost savings of GEBs would therefore extend beyond the owners and tenants of the GEBs themselves. By 2040, the BTO calculates, GEBs could save the US power system more than $100 billion in cumulative electricity generation and transmission costs.
What Are the New US Goals for GEBs?
In the GEB roadmap, released May 17 in conjunction with the White House announcement, the US Department of Energy laid out a goal of tripling the energy efficiency and demand flexibility of buildings by 2030, relative to 2020 levels. To reach that goal, the roadmap articulates 14 recommendations, from enhancing R&D for smart-building technologies to policy options for encouraging integration of GEB practices.
Among the roadmap’s recommendations is that government agencies should “lead by example” — deploying GEB measures in government-owned buildings to demonstrate the benefits and provide valuable insights and best practices for more widespread deployment. Already, the vast majority of US states have adopted requirements for energy usage or efficiency in government buildings, and demand flexibility could become a valuable tool for meeting those requirements.
At the federal level, the savings from GEBs would be significant. The US General Services Administration (GSA) is the nation’s largest landlord, with nearly 10,000 buildings and more than 375 million square feet of real estate under its control. In a 2019 cost-benefit analysis, RMI found that the GSA could save $50 million annually (about 20 percent of its energy expenditures) by implementing GEB measures across its portfolio of buildings. In all six locations that RMI studied in the GSA analysis, the payback period for GEB improvements was less than four years (and in some cases less than a year), demonstrating the soundness of the investment for the government and for taxpayers.
Next Steps at the Federal Level
A new report from the National Renewable Energy Laboratory (NREL) provides a blueprint for the GSA to select buildings that are ideal candidates for cost-effective GEB projects. The report also lays out strategies and best practices for integrating GEB measures into the various phases of contract development for energy-focused building retrofits.
The NREL report notes that the sheer number of buildings managed by the GSA would allow the agency to screen its real estate portfolio for the highest-value GEB candidates before applying the early lessons learned in implementing GEB measures in performance contracts. NREL also notes that the buildings with the greatest economic potential for grid-interactive efficiency tend to share features such as time-of-use energy rates, high demand charges for a building’s peak energy usage, or utility or state programs that incentivize utility customers to be responsive in their energy demand.
One of the challenges identified by the new reports from BTO and NREL is the maturity and availability of some technologies that would optimize GEB implementation. Systems for coordinated, whole-building automation in response to signals from the grid are among the emerging technologies that will be needed to maximize GEBs’ benefits. The GSA’s Proving Ground program is evaluating some of these building control systems in demonstration projects, and the learnings from those evaluations should help to further shape best practices for implementing GEB projects nationwide.
The Path to 2030 and Beyond
By integrating energy efficiency, distributed energy generation technologies, and demand flexibility into its buildings, the GSA can help to advance the state of the art in grid-interactive efficient buildings. The proof points from GEB projects in the federal government’s building portfolio will not only help advance the DOE goal of tripling demand flexibility and efficiency measures by 2030. They should also make for a cleaner, more resilient grid powering smarter, more efficient buildings—all while saving taxpayers money.
For a while it seemed like a bit of a hail mary, as many thought that most of the industry was already committed to the SAE CCS standard for fast charging.
For a time, though, VW was a holdout. It wasn’t until December 2023 – half a year after Ford’s announcement – that VW committed to switching to NACS in 2025 (though really, they were just waiting for SAE’s certification of the standard, which was completed a few days prior).
Well, now we’re here in 2025, and VW says they’re ready to step up.
Today at CES, VW PR director Mark Gillies confirmed to PC Magazine that “we get access to the network in June/July, when we have an official VW adapter.”
Currently, VW isn’t even listed on Tesla’s NACS page, which mentions that Ford, Rivian, GM, Volvo, Polestar, and Nissan vehicles can all charge on Tesla’s charging network. The only manufacturer currently listed as “coming soon” is Mercedes-Benz, and generally manufacturers have spent a few months on that page before gaining access.
So this is a bit of a surprise announcement from VW, but certainly welcome. Then again, we have witnessed miscommunications in this respect before, so maybe Tesla just didn’t want to jump the gun again, like it did with Nissan. (Update: It turns out VW jumped the gun this time, as a previous version of this article quoted VW saying it will get access in March, not June).
VW’s confirmation today doesn’t specify whether its sub-brands, Audi and Porsche, would be on the same timeline. But since the three brands committed to NACS in a joint announcement, it stands to reason that they could be on the same timeline to get access and adapters.
Update: A previous version of this article stated that VW cars will get access in March, and adapters in June. It turns out, both access and adapters will come in June.
Electrek’s Take
Given that VW was one of the last manufacturers to officially adopt NACS, it’s nice to see them keeping to their timeline – and possibly beating some other manufacturers to the punch too.
This could also be a sign that we’ll start seeing more of a flood of manufacturers getting access soon. The transition is supposed to happen “throughout 2025” after all, and, well, that’s where we are. But the casual nature with which VW has confirmed this timeline suggests that perhaps this transition is really about to get on a roll.
So, look forward to having a lot more interesting sights to see at Superchargers, as the menagerie gets more varied throughout the year.

US EV sales will continue to grow in the year ahead, accounting for 1 in 4 vehicles sold in 2025, according to Cox Automotive’s 2025 Outlook.
Cox Automotive is kicking off 2025 with a bright outlook for the auto market. After wrapping up 2024 on a high note, the US auto industry seems to be on a solid path forward, despite some uncertainties. In fact, Cox is predicting that it’s going to be the best year for the auto market since before the pandemic, in 2019.
With the exception of Stellantis and Tesla, nearly every automaker posted higher sales year-over-year overall in 2024. General Motors was the top-selling automaker in 2024, while Honda and Mazda delivered strong growth.
The US market posted record EV sales in 2023 and 2024, and this trend is expected to continue in 2025. Cox Automotive predicts that EVs will account for approximately 10% of the market total in the year ahead, up from roughly 7.5% in 2024.
Hybrids and plug-ins will account for about 15% of the market, and sales of ICE vehicles will tumble to 75% of total volume, the lowest level on record.
EV growth will be supported by around 15 additional EV models entering the market, consumers deciding to buy before the Trump administration cuts the $7,500 tax credit, and state-level incentives countering potential federal cuts. The rapid expansion of the EV charging network is also contributing to this growth.
Cox asserts that “consumers are feeling better about the road ahead, as the US election was smoothly settled, interest rates are below their peaks, and the job market has stabilized.”

With more models hitting the market and massive incentives, electric vehicles are more affordable than ever. However, with Trump’s transition team reportedly planning to end the EV tax credit, the savings may soon disappear. Here are the EVs you can still lease for under $300 a month in January.
2024 was another record year for EV sales in the US. Many automakers, including GM, Ford, Hyundai, Kia, and Honda, sold significantly more electric cars last year than in 2023.
According to Cox Automotive, electric vehicles are expected to represent 7.5% of all US auto sales in 2024. Although all December and full-year 2024 sales numbers have yet to be released, EV sales hit a record in November. With over 116,000 units sold, electric cars achieved an 8.5% market share.
A big reason behind the growth was new models, like the Honda Prologue, which was the third best-selling EV in the US in November. That’s after deliveries began in just March.
Honda sold over 33,000 Prologues in the US last year, with nearly 7,900 in December alone. With over 114,000 EVs sold, GM outpaced Ford’s roughly 97,900. Meanwhile, Hyundai, Kia, and others reported record EV sales in 2024.
Although a big reason behind the sales surge is due to new options, massive incentives have made EVs even cheaper to lease than gas-powered cars.
What EVs are for lease for under $300 in January 2025?
With additional discounts on top of the $7,500 federal EV tax credit, some discounts are reaching as high as $10,000 to $20,000 off MSRP. In Q3, EV incentives averaged over 12% of the average transaction price (ATP), nearly double the industry average of 7%.
Despite having a starting MSRP almost double that of a Civic Sedan, you can lease a Honda Prologue for less in many parts of the US.
The 2024 Honda Prologue is listed at just $229 for 36 months in California and other ZEV states. With $1,299 due at signing, the effective monthly payment is $265. That’s for the EX (FWD) trim, which has a range of up to 296 miles.
In other parts of the country, don’t worry — Honda is still offering Prologue leases starting at $249 per month. You can also opt for a 0% APR.
