Why Grid-Interactive Efficient Buildings Feature Prominently in Joe Biden’s Plans
Originally published on RMI.org.
By John Matson
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.
In a bid to get it above the $1.00/share NASDAQ-required minimum, fledgling EV brand Polestar ($PSNY) is rumored to be considering a 1:30 reverse stock split that could see the per-share price rocket up to nearly $16.
Geely-owned Volvo spinoff Polestar is working as hard as Tesla to prove that stock prices have little or nothing to do with traditional business fundamentals in 2025.
That’s because Polestar posted a 36.5% increase in retail sales and a heady 48.8% increase in revenue (to $2.17 billion) over the year before, Polestar’s share price has plummeted more than 35% in a matter of a few weeks – culminating in an unwelcome nastygram from NASDAQ threatening to delist the company’s shares from the NASDAQ if they didn’t climb back up above $1.
It looks bad
To goose the share price, CarScoops is reporting that Polestar aims to move forward with the reverse stock split before the end of 2025. The expected 1:30 reverse split would boost the PSNY price to an estimated $15.90 per share at current prices, keeping the brand well out of risk of a delisting.
In a reverse stock split, each share of the company is converted into a fraction of a share – so, if a company announces a one for ten reverse stock split (1:10), every ten shares that you own will be converted into a single share. In a 1:30 reverse split like the one rumored here, every thirty shares in Polestar would become a single share.
The reverse split increases share price, but it’s not without risk:
A company may declare a reverse stock split in an effort to increase the trading price of its shares – for example, when it believes the trading price is too low to attract investors to purchase shares, or in an attempt to regain compliance with minimum bid price requirements of an exchange on which its shares trade … investors may lose money as a result of fluctuations in trading prices following reverse stock splits.
That’s especially relevant because, despite the increased sales and revenue, the company is also posting increased losses. Through September, the brand posted a $1.56 billion net loss compared to an $867 million loss in the first nine months of 2024. The company is also getting hit hard by Trump-imposed tariffs in the US and increased downward pressure on pricing coming from aggressive post-tax credit discounts from rival brands like BMW and Kia.
If the split does happen, here’s hoping Polestar can make the most of their borrowed time and they don’t end up like Lordstown Motors or Faraday Future – two brands that have pulled similar reverse stock splits with dubious results.
Electrek’s Take
Product-wise, at least, Polestar’s future appears to be bright. The new 3 crossover is a viable competitor to the industry-leading Tesla Model Y, and the upcoming Polestar 4 and 5 models seem like winners, too. To drive that point home, Polestar is promoting up to $18,000 in lease incentives to lure Tesla buyers into their showrooms.

With its sleek, uncluttered styling and more than 100 miles of battery-electric range before the extended range electric sedan’s gas engine kicks on, maybe the new Nissan N6 really should have been the next Maxima!
Struggling Japanese carmaker Nissan is dealing with an aging lineup and a brand identity driven more by subprime financing than any suggestion of reliability or sportiness here in the US – but overseas? The brand is rolling out hit after hit, and the latest Nissan N6 plug-in sedan promises exactly the sort of entry-level panache that could change its American fortunes.
“Under our Re:Nissan plan, we are redefining what Nissan delivers today and beyond,” explains Nissan President and CEO Ivan Espinosa. “It’s about strengthening our core, reigniting Nissan’s heartbeat, and creating products that inspire excitement and trust. It is about a sharper, more focused product strategy, a stronger brand, and a renewed commitment to our customers. Integral to this transformation is China — an essential market whose speed, technological leadership, and customer insights are setting the pace for the global auto industry.”
Developed by the Nissan Dongfeng JV in China, the new N6 is more compact that the well-received N7 BEV. In fact, the new Nissan N6, at 190.1″ long, compares nicely to the 192.8″ length of the most recent (and largest-ever) US Maxima, discontinued in 2023. Like the Maxima, the top-shelf version features modern, near-luxe features like soft, leather-like surfaces, LED mood lighting, multi-way adjustable seats, and mimosas or something.
Mimosas or something
The four or five passengers inside the N6 are propelled down the road exclusively by the car’s 208 hp electric motor, which is efficient enough to take you 112 miles on a full charge of its 21.1 kWh LFP battery. Once that charge is depleted, a 1.5L gas engine kicks on as a high-efficiency generator to keep the good times rolling.
Nissan says the N6′ exterior design, “features a V-Motion signature grille and expressive LED lighting at the front and rear.” And says that the car’s crisp lines give it, “a confident, dynamic presence.”
All of which sounds good on its own, but sounds absolutely miraculous when you consider the car’s Chinese price: ¥106,900 – or about $15,000 US for the base Nissan N6 180 Pro, as I type this.
Even with a nearly 100% markup to give it a $29,990 price tag in the US, I think the N6 would be a huge hit in the North American market. And – good news! – thanks to Canada’s apparent willingness to give Chinese carmakers a shot, we might find out if I’m right somewhat sooner than later.
Check out the Nissan N6 image gallery, below, then let us know what you think of the car’s US and Canadian appeal in the comments.
