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.

Republicans introduce bill that would hand US EV lead to China

Republicans introduce bill that would hand US EV lead to China

Republicans have introduced a bill to eliminate the US EV tax credit in the Inflation Reduction Act, with the effect of slowing US progress on EV manufacturing, thus handing the lead in EV manufacturing to China.

How the Inflation Reduction Act helps American health, economy & manufacturing

The Inflation Reduction Act included hundreds of billions of dollars of climate spending, much of which was allocated to EV tax credits, both for personal and commercial vehicles. These credits were an extension and expansion of the $7,500 EV tax credit first introduced in 2008.

But those credits were limited to 200,000 cars per manufacturer, a cap which some manufacturers had hit and more were going to hit. So the Inflation Reduction Act improved access to those credits, removing the cap and setting up a way for the credits to be available upfront at the point of sale, meaning that lower-income buyers can qualify for the credits and get them immediately instead of waiting to file their taxes.

However, it limited the credits in some important ways as well – namely, by ensuring domestic production of electric vehicles in order to qualify, and setting limits on high-income buyers so the credits go to people who need them rather than those who don’t.

It also added a $4,000 used EV tax credit, which is limited to even lower income groups.

There are ways around some of these limitations and some restrictions have been loosened to allow industry to catch up. But these restrictions have nevertheless fueled a renaissance in American auto manufacturing, with many manufacturers announcing new factory investments in the US.

In fact, since President Biden started his EV push, oer $210 billion has been invested in new or expanded factory projects, which will create EV 250,000 jobs, with more to come.

These commitments stand to make the US into an EV manufacturing powerhouse – we’re already doing pretty well in EV production, largely led by Tesla. But Chinese EV production and demand are rising rapidly and automakers are waffling in the face of it – so government must be clear that we are committed to building this industry long-term.

The IRA also represents the largest climate commitment made by any country in the world, ever, by dollar value. The hundreds of billions of dollars allocated, largely to EV-related tax credits but also to many other climate programs, are a commitment still unmatched by any other country. As an added bonus, the bill actually brings in more revenue than it costs due to tax reforms targeting wealthy corporate and individual tax cheats.

Republicans are lying about their bill’s effects

So, no wonder that republicans, a party that seems to actively oppose anything that would benefit American manufacturing or the environment that Americans live in, would introduce an act to eliminate much of the benefit from the Inflation Reduction Act.

The new act, fittingly called the “ELITE” Vehicles Act (surely named for republicans’ elite fossil fuel donors which it aims to benefit at the expense of everyone else), aims to eliminate the clean vehicle credit for new, used, and commercial electric vehicles.

The act was introduced by John Barrasso, a republican senator from Wyoming who has received $526,425 from the oil & gas industry in this senate election cycle. Not only that, but Wyoming’s main industries are all tied to oil, putting the lie to the assertion that this act is intended to do anything more than benefit an industry which is responsible for millions of deaths per year.

The act’s advocates say that IRA credits – which are limited to lower-income buyers, particularly the used EV credit – are a giveaway to the wealthy (who don’t qualify for them), and that the credits allow Chinese EVs into the US (which they in fact explicitly disallow through the domestic manufacturing provisions mentioned above).

Notably, the act doesn’t do anything to get rid of the $760 billion in subsidies received by polluting industry each year in the US. This could be done through making polluters pay for the pollution they cause. If subsidy elimination were the act’s main concern, then that’s a rather big target that the act ignores – because, of course, the fossil fuel industry wouldn’t like it if their free license to harm the health of Americans were revoked.

The actual effect of rolling back these credits would be to make EVs less affordable for Americans, to ensure that those same Americans have more misery forced on them by pollution from the industry that bribes Barrasso, and to discourage American EV manufacturing and consumer uptake which would have the effect of handing over the lead in global EV manufacturing to China.

How Chinese auto benefits and the US is harmed by repealing the EV credit

Chinese EV manufacturing and consumer demand are both currently skyrocketing, and China is rapidly increasing exports of EVs to overseas markets – particularly Europe at the moment.

But Chinese companies would love to sell EVs in the US, and would likely love to see the government tack $7,500 onto the price of US-built EVs, which would only make Chinese-built EVs much more competitive to the pocketbooks of the American consumer. Barrasso’s bill would do exactly that – make Chinese EVs more competitive, and the US auto industry less so.

And since EVs provide local air quality benefits, which stands to reason and which we’ve already seen in areas with high penetration, reducing EV adoption would also make Americans sicker and fill up American hospitals more.

While Barrasso claims that the bill would do the opposite of the things that it would actually do, it’s hard to believe that anyone would be ignorant enough to believe it would actually have the effects he claims. We don’t think that even he thinks that – we think he’s just playing politics, and saying whatever will make his fossil overlords happy.

In short, John Barrasso, author of the act, is lying to protect the industry that bribes him.

So far, the act has only been introduced in the Senate, and has not made it through committee or to a vote. It is sponsored by 19 republican senators, many of whom come from states with significant oil industry presence. If somehow passed, it would almost certainly be vetoed by President Biden, so it is not likely to make it into law under the current government (though that could change in November, which is something to keep in mind when filling out your ballots).

But even if it doesn’t make it into law, it still functions as a way for republicans to show their intent – to cost you money, to harm your health, and to hand the keys of the future of the auto industry over to the country which the US considers its main geopolitical rival.

Record number of EV chargers installed in the UK last quarter

A record number of public electric vehicle charging stations were installed in the UK this quarter, as charging companies struggle to keep up with the growing number of plugin cars on British roads.

Almost 6,000 new EV chargers were installed in the UK during the first three months of 2024, according to quarterly figures from data company Zapmap and published by the UK’s Department for Transport. Approx. 25% (about 1500) were DC fast chargers.

There were nearly 60,000 public vehicle chargers energized and active in the UK as of April 1st, up nearly 49% compared to 2023 and nearly 2x the number of public chargers available in 2022. Ben Nelmes, CEO of automotive think tank New AutoMotive, says the recent expansion of the UK’s electric vehicle charging infrastructure has brought public charging to areas that had previously been poorly served. This is thanks, in part, to local governments gradually taking advantage of central government grants to put more EV chargers in the ground.

“I think there is a coming together of two things,” Nelmes told The Guardian. “Some of the barriers have been mitigated. And the private sector has woken up to the opportunity.”

Another tidbit from that Guardian article was a survey conducted by the Electric Vehicle Association of some of the UK’s one million plus EV drivers. The survey found that only 6% of EV drivers in England reported experiencing range anxiety either very often or fairly often, while 94% of EV drivers said they had range anxiety occasionally, rarely, or never.

Electrek’s Take

Electric Cab London
The all-electric TX Black Cab: Credit: LEVC

More than half of the more than 15,000 famous London “black cabs” are now electrified (effectively EVs with range-extending ICEs on board), with the majority of London’s largest taxi and minicab services committed to operating fully electrified fleets by 2025.

Let that serve as your gentle reminder that EV sales are down, except at Ford, Cadillac, GMC, Kia, Hyundai, Toyota, Nissan, Honda, Acura, Volvo, Chrysler, etc. …
