Real estate is a key puzzle piece in achieving the U.S.’ climate goals, according to federal officials.

Residential and commercial buildings account for 31% of the nation’s greenhouse gas emissions, after accounting for “indirect” emissions like electricity use, according to the Environmental Protection Agency. That’s more than other economic sectors like transportation and agriculture.

The Biden administration has adopted various policies to cut residential emissions.

The Inflation Reduction Act, enacted in 2022, offers financial benefits including tax breaks and rebates to homeowners who make their homes more energy-efficient, for example. The White House also recently issued guidelines for buildings in order to be considered “zero emissions,” meaning they are “energy efficient, free of onsite emissions from energy use and powered solely from clean energy,” according to the Department of Energy.

Morgan Wojciechowski, 33, is among the first homeowners to get that federal “zero emissions” label. (That assessment was bestowed by the third-party firm Pearl Certification.)

Wojciechowski, her husband Casey, and their three dogs — Dixie, Bo and Charlie — moved into the newly built residence in Williamsburg, Virginia, in August 2023.

Wojciechowski, who is also the president of Healthy Communities, a local real-estate developer focused on sustainable construction, spoke with CNBC about her new home, its financial benefits and how consumers can best upgrade their homes to be more efficient.

The conversation has been edited and condensed for clarity.

Greg Iacurci: What does it mean for your home to be considered ‘zero emissions’?

Morgan Wojciechowski: It’s a very, very, very highly efficient home that’s all-electric. Those are kind of the first two bullet points of the White House definition.

The third part is we are part of the green energy program with [our power provider] Dominion. Not only am I producing solar [energy] and any excess is going back onto the grid, but the power from the grid coming into my home is clean and sustainable. It’s about $10 extra a month for me to get that clean energy.

GI: How much did your house cost to build?

MW: Like $1.1 million.

GI: And how big is the house?

MW: 5,800 square feet.

It’s a large home. But mine is not what everybody’s doing. My home was my personal project because I believe in sustainability and wanted to do it in a home that would be my forever home. But one that’s more replicable would be like what [Healthy Communities] builds at Walnut Farm, which is like 1,500 square feet. We’re selling it for $433,000.

GI: Can you break down your home’s estimated savings?

MW: Our utility bills are projected to be about $917 a year with [solar] panels, or around $80 a month.

The annual savings are $7,226 [relative to an average U.S. home, according to rater TopBuild Home Services]. That’s just from the efficiency of the home with solar.

If you took the solar production away, I would be saving $5,431 annually. The solar offsets it.

GI: What do you mean solar offsets it?

MW: You create energy. Your home uses that energy and sends excess energy back to Dominion. Those credits are stored in an account, and then those credits offset your bill. It’s called net metering.

GI: So the power company is paying you that money?

MW: Those credits are applied to your next billing cycle. They offset your overall utility bill, and that’s where your savings come in.

Solar panels only make sense if you build an energy-efficient home that’s really all-electric.

GI: Why is that?

MW: You have to have a home that’s constructed energy-efficiently enough or retrofitted — by replacing your windows with higher-grade windows, adding insulation — so that you will need fewer panels on your rooftop, so you have a quicker return on your investment. Solar only makes sense if you’re going to have a return on your investment within a few years.

GI: That makes solar more attractive?

MW: If you don’t do energy-efficient upgrades to a pre-existing home or if you don’t build a home that’s energy-efficient enough, you have to add more panels to compensate for the lack of energy efficiency. And if that number gets too big it turns people upside down.

Solar has to make sense with the home that you’re putting it on, or else, don’t do it. Maybe just upgrade your windows, add insulation, condition your crawl space, upgrade your mechanical systems.

There are a lot of things consumers can do. You don’t have to do it all at one time. You don’t have to have a solar home to be zero emissions; you have to have an energy-efficient house that’s all-electric, and you have to buy renewable energy from your utility company.

That’s extremely approachable. Lots of people can do that. Everybody can join in at their level of sustainability.

GI: How do you recommend people get started?

MW: I would tell a consumer, why don’t you start with windows and doors. That’s a very easy one. Do that and see how you notice any [efficiency] changes.

In a lot of older homes windows are very old and they leak. Air is coming in and out. If you think about it, a house is like an envelope. You you want to seal the inside of your home the best that you can.  

I would hit insulation next.

A lot of older homes have HVAC systems, duct work inside of their attic. Insulate it so that it’s a conditioned space, so that those building systems don’t have to work in overdrive to keep up with really hot temperatures or really cold temperatures. That keeps it more energy efficient.

And there are tax incentives [available] for energy-efficient upgrades to your home. Consumers can get and write them off, so that’s attractive to people as well.

GI: If you’re a renter, there are certain things that are out of your control. I suppose you can ask your landlord.

MW: Depending upon what your rental situation is. I feel like that’s a little bit more daunting, to change someone else’s mind. Once you get to your own home, eventually, then you have more say of what you can do.

Until then, you could be mindful about the energy you use. Turn lights off. I mean, that’s a real thing. People don’t turn lights off. I mean, even though I have a really efficient home, I have timers on things because I don’t want to be wasting energy. That’s an easy one that anybody could do.

Here's our best look at the Kia EV4 so far, including the interior [Video]

Kia confirmed it will launch the EV4 this year as it fills out “a full lineup of popular EVs.” According to Kia, the EV4 is “an entirely new type of EV sedan with a distinct style and sports car-like proportions. However, it’s expected to be much cheaper than your average sports car. With its official debut around the corner, we are getting a closer look at what we can expect from the Kia EV4, including the inside. Check it out below.

The EV4 was revealed as a concept in October 2023 alongside the EV3 and EV5 as part of Kia’s new mass-market electric vehicle lineup.

After launching the EV3 in Korea, it’s now arriving in Europe and other overseas markets. The EV5 was initially launched in China, but Kia will bring the lower-priced electric SUV to Europe, Korea, Australia, and other regions in 2025.

Kia announced earlier this week that “the sedan-type electric vehicle EV4 will be launched sequentially around the world” after reporting Q4 and full-year 2024 earnings.

The EV4 will join the EV3, EV5, EV6, and EV9 to complete Kia’s “EVs for all,” with prices ranging from around $30,000 to upwards of $80,000. At the time, Kia said it plans to “significantly” and “rapidly” expand its electric car lineup, and it’s already making good on its promise.

Check out the Kia EV4, inside and out

Although we’ve already seen it a few times in public, including in the US late last year, a new video from HealerTV gives us a better idea of what to expect from the Kia EV4, including its interior.

One of the first things you will notice is the unique exterior profile. It appears to maintain much of the concept’s design with bold character lines and a streamlined silhouette.

Although not shown, the EV4 will feature Kia’s new ccNC (connected car Navigation Cockpit) infotainment system with dual 12.3″ driver display and infotainment screens.

The video shows what appears to be a spacious interior despite its expected smaller size. You can see how a car seat fits in the back seat with plenty of space.

Although prices and other specs will be revealed closer to launch, the EV4 is expected to start at around $30,000 to $40,000, depending on the market. Like the EV3, it’s also based on Hyundai’s E-GMP platform, which should deliver around 375 miles (WLTP) range, if not more, with the larger 81.4 kWh battery.

A hatchback EV4 model was also spotted out in public last year. The variant will likely be aimed at the European market.

Would you buy Kia’s electric sedan for around $35,000? Let us know in the comments below.

This cool tech will turn existing fiber optics into smart sensors on Minnesota’s grid

This cool tech will turn existing fiber optics into smart sensors on Minnesota's grid

Not-for-profit power cooperative Great River Energy, which serves 1.7 million people across Minnesota and Wisconsin, has partnered with Prisma Photonics to roll out real-time monitoring technology across 90 miles of transmission lines in northern Minnesota. Prisma Photonics will provide its PrismaPower system to track threats like wildfires, ice, wind, and physical damage to the Minnesota grid.

The multi-year project will install PrismaCircuit and PrismaClimate across five key transmission lines connected to four substations using existing fiber optic lines. The goal is to strengthen the grid ahead of Minnesota’s next winter season. These lines, spread across central and northern Minnesota, will now be under constant surveillance without the need for traditional sensors.

“We’re leveraging innovative new technologies that maximize our existing infrastructure investments,” said Priti Patel, vice president and chief transmission officer at Great River Energy. “This solution allows us to utilize our current fiber optic network in a new way to increase resilience in areas of northern and central Minnesota.”

Instead of installing physical sensors on power lines, Prisma Photonics’ technology taps into fiber optic cables already in place, transforming them into an advanced sensing system. Here’s how the company’s works:

Prisma Photonics Fiber Sensing works by connecting an optical interrogator unit into a standard single-mode optical fiber. It is one fiber, part of a cable laid alongside the monitored asset, probably for communications purposes. The Interrogator transmits optical pulses that propagate down the fiber. A minute fraction of the light is reflected from each point along the fiber. The Interrogator measures the reflected light to determine the strain, temperature, pressure, and other quantities over hundreds of kilometers of fiber with sub-meter resolution. The fiber is turned into a continuous acoustic sensor – as if there were tens of thousands of microphones spanning hundreds of kilometers.  

Prisma Photonics says this means faster deployment, no service interruptions, and no need for specialized crews in all weather conditions.

Dr. Eran Inbar, CEO of Prisma Photonics, said, “Our partnership with Great River Energy demonstrates how utilities can extract additional value from their existing infrastructure to enhance grid resilience while avoiding traditional sensor-based solutions’ complexity and maintenance requirements.”

Mitsubishi will finally launch its first EV in the US in 2026 and it may twin with the Nissan LEAF

Mitsubishi confirmed plans to finally launch its first EV in the US in 2026. The new electric car is expected to look similar to Nissan’s next-generation LEAF, which will debut later this year.

Mitsubishi plans to launch its first EV in the US in 2026

After notching its highest sales in the US since 2019 last year, Mitsubishi intends to keep the momentum going with a revamped lineup, including its first electric vehicle.

Mitsubishi told US dealers during a meeting earlier this week (via Automotive News) that the brand’s first EV will arrive in the US in 2026 alongside a new Outlander model.

According to sources, it will be a small electric crossover, similar to what the next-gen Nissan LEAF is expected to look like. Nissan is updating the iconic hatch with a new style closer to the Ariya, its electric SUV.

The new LEAF will use the same CMF-EV platform that underpins the Nissan Ariya. Nissan said its Chill-out concept from 2021 previewed the next-gen LEAF model. It will be more of a crossover coupe rather than the hatchback we are used to seeing.

Nissan is expected to unveil the new model later this year. Earlier this month, the new LEAF was spotted testing in the US, giving us our best look at the new EV so far.

Although RC Hill, chairman of the Mitsubishi National Advisory Board, said US dealers would “embrace” the brand’s first EV, it’s not expected to replace the Mirage. “It’s probably a solution to the OEM problem, but not a solution to move volume,” he explained.

The Mirage was the brand’s second-best-selling model in the US last year, behind the Outlander, but Mitsubishi ended production in December. To make up for it, Mitsubishi may cut Outlander Sport prices and introduce a new lower-priced trim ahead of its first EV arriving.

Although Mitsubishi was initially included in Nissan and Honda’s EV merger plans, the automaker is reportedly considering backing out.

With a wave of new electric crossovers and SUVs arriving in the US from Hyundai, GM, Volvo, Rivian, and several others, will Mitsubishi be able to stand out? Would you buy a Mitsubishi EV? Let us know in the comments below.
