Construction is underway in St. Paul, Minnesota, on a major affordable housing development that will combine solar, geothermal and all-electric appliances to create one of the region’s largest net-zero communities.

Twin Cities Habitat for Humanity broke ground in June on a four-block, 147-unit project on the site of a former golf course that’s being redeveloped by the city and its port authority, which made the decision to forgo gas hookups. 

Affordable housing and Habitat for Humanity builds in particular have become a front line in the fight over the future of gas. The organization has faced criticism in other communities for accepting fossil fuel industry money and partnering with utilities on “net-zero” homes that include gas appliances. It’s also built several all-electric projects using advanced sustainable construction methods and materials.

The scale of the Twin Cities project is what makes it exciting, according to St. Paul’s chief resilience officer Russ Stark. 

“We’ve had plenty of motivated folks build their own all-electric homes, but they’re one-offs,” he said. “There haven’t been many, if any, at scale.”

Stark added that the project, known as The Heights, was made possible by the federal Inflation Reduction Act. 

“I think it’s fair to say that those pieces couldn’t have all come together without either a much bigger public investment or the Inflation Reduction Act, which ended up being that big public investment,” he said.

A vision emerges

Port Authority President and CEO Todd Hurley said his organization bought the property in 2019 from the Steamfitters Pipefitters Local 455, which maintained it as a golf course until 2017. When no private buyers expressed interest in the property, the Port Authority bought it for $10 million.

Hurley said the Port Authority saw potential for light industrial development and had the experience necessary to deal with mercury pollution from a fungicide the golf course staff sprayed to kill weeds.

“We are a land developer, a brownfield land developer, and one of our missions is to add jobs and tax base around the creation of light industrial jobs,” Hurley said.

The Port Authority worked with the city’s planning department on a master plan that included housing, and it solicited developers to build a mix of market-rate, affordable and low-income units. The housing parcels were eventually sold for $20 million to a private developer, Sherman Associates, which partnered with Habitat and JO Companies, a Black-owned affordable and multi-family housing developer.

“Early on, we identified a very high goal of (becoming) a net zero community,” Hurley said. “Everything we have been working on has been steering towards getting to net zero.”

Twin Cities Habitat President and former St. Paul mayor Chris Coleman said the project met his organization’s strategic plan, which calls for building bigger developments instead of its traditional practice of infilling smaller lots with single-family homes and duplexes. The project will be the largest the organization has ever built in the Twin Cities.

Coleman said the Heights offered an opportunity to fill a need in one of St. Paul’s most diverse and economically challenged neighborhoods and “be part of the biggest investment in the East Side in over 100 years.”

The requirement for all-electric homes merged with Habitat’s goal of constructing more efficient and sustainable homes to drive down utility costs for homeowners, he said. Habitat built solar-ready homes and sees the solar shingles on its homes in The Heights as a potential avenue to producing onsite clean energy.

Zeroing in on net zero

Mike Robertson, a Habitat program manager working on the project, said the organization worked with teams from the Minneapolis-based Center for Energy and Environment on energy modeling.

“The Heights is the first time that we’ve dived into doing an all-electric at scale,” Roberston said. “We have confidence that these houses will perform how they were modeled.”

Habitat plans to build the development to meet the Zero Energy Ready Home Program standards developed by the U.S. Department of Energy. Habitat will use Xcel Energy’s utility rebate and efficiency programs to achieve the highest efficiency and go above and beyond Habitat’s typical home standards.

The improved construction only adds a few thousand dollars to the overall costs and unlocks federal government incentives to help pay for upgrades, he said.

The nonprofit will receive free or reduced-cost products from Andersen Windows & Doors and other manufacturers. GAF Energy LLC, a solar roofing company, will donate solar shingles for over 40 homes and roofing materials. On-site solar will help bring down energy bills for homeowners, he said.

Chad Dipman, Habitat land development director, said the solar shingles should cover between half and 60% of the electricity the homes need. Habitat plans to use Xcel Energy incentive programs to help pay for additional solar shingles needed beyond those donated. 

Habitat will install electric resistance heating technology into air handlers to serve as backup heat for extremely cold days. Dipman said that the air source heat pumps will also provide air conditioning, a feature not available in most Habitat properties in Minnesota.  

Phil Anderson, new homes manager at the Center for Energy and Environment, has worked with Habitat on the project. He said the key to reducing the cost of heating and cooling electric homes is a well-insulated, tight envelope and high-performance windows. Habitat will build on its experience with constructing tight homes over the past decade, he said.

“Overall, the houses that we’ve been part of over the last almost ten years have been very tight homes,” Anderson said. “There’s just not a lot of air escaping.”

Habitat’s national office selected The Heights as this year’s Jimmy & Rosalynn Carter Work Project, named after the former president and his wife, two of Habitat’s most famous supporters. The work project begins September 29th and will receive as visitors Garth Brooks and Trisha Yearwood, who now host the Carters’ program.

Robertson said thousands of volunteers from around the country and the world will help put up the homes. The Heights project “raises a lot of awareness for Habitat and specifically for this development and the decarbonization efforts that we’re putting into it,” he said.

The Heights’s two other housing developers continue raising capital for their projects and hope to break ground by next summer. Habitat believes the project will meet its 2030 completion deadline.

As more energy intensive industries take root, we must protect our residents from both the increases in our power needs and our monthly power bills.

The following commentary was written by Sophie Loeb, policy analyst at the Center for Progressive Reform, and Michelle Carter, director of clean energy campaigns at the North Carolina League of Conservation Voters. See our commentary guidelines for more information.

If your energy bills seem high this very hot summer, brace yourself. Without drastic measures to curb pollution, summers will be hotter and staying cooler will be more expensive. Unfortunately, the biggest strain on our future electricity bills isn’t our air conditioning, our electric cars, or even our businesses — it’s artificial intelligence (AI).

Data centers have been consuming power all over the country since the 1960s. As the Internet has rapidly been integrated into our lives, so too have data centers. Big data’s assault on North Carolina continues unabated, creating more demand on our energy system and raising our bills.

The new wave of artificial intelligence has the power to change the very nature of our society, in many ways for the worse. Data centers running AI require a constant and consistent power supply, something the utilities in the Southeast have struggled with for decades. These centers raise our bills while providing virtually no benefits to our communities.  Data centers across the nation have been given tax incentives, lower electricity rates, and have created few jobs for the amount of resources they use.

As more energy intensive industries take root, we must protect our residents from both the increases in our power needs and our monthly power bills. Unfortunately, Duke Energy’s plans to meet the growing needs of industry expose us to further financial and health risks. Duke Energy claims that their plan, which proposes the biggest methane gas build out in the nation, is needed to meet growing demand, particularly for data centers.

Duke has also warned that ratepayers’ bills will rise if they don’t build these plants, but the opposite is true. Building out solar and utility-scale battery storage instead of gas would yield $8 to $12 billion in electricity savings by 2030 and $18 to $23 billion in savings by 2050. An Environmental Defense Fund (EDF) analysis shows that, for Duke Energy Carolinas customers, increases in fuel costs account for roughly 67 percent of rate increases since 2017. The research is clear: more dirty methane gas means higher energy bills, both now and in the future.

According to Goldman Sachs, data centers will require a $50 billion expansion in electricity generation infrastructure to meet the industry’s demand. This money to build big power plants will come directly from North Carolina consumers like you and me without proper protections from the state.

Why should residential customers, particularly those who struggle to pay their energy bills, pay for these costly plants? Who really benefits from the environmental, social, and economic burdens of artificial intelligence?

Unfortunately, protections from the pressures of data centers are nowhere to be found — for now. Duke Energy has undertaken deals with Microsoft, Google, and other major power consumers to expand renewable generation and protect our grid. Through these agreements, large customers can transition to clean energy while lessening the burden of their power demands on the rest of Duke’s consumer base.

Data centers must be subject to these same agreements — and more — to keep North Carolina ratepayers safe from massive price increases. Consumers deserve transparency and accountability with any new data center project in our state.

In lieu of data centers, North Carolina should invest in good, clean energy manufacturing jobs that promote economic development, resilience, and environmental sustainability. Already, the Inflation Reduction Act is slated to create almost 40,000 jobs by 2030. Tech companies could support these efforts with electric vehicle manufacturing plants, solar panel and battery storage manufacturing facilities, and further build the Southeast as a hub of clean energy manufacturing.

To better center people over tech companies and promote an affordable energy transition:

  1. Utility commissions should require utilities to highlight explicit data on load growth from data centers so additional capacity is not passed on to residential customers.
  2. Regulators should prohibit data centers from receiving subsidized industrial use rates.
  3. The General Assembly should pass legislation enhancing stronger consumer protection laws for electricity ratepayers.
  4. The state should form an Office of the People’s Counsel to protect customers from absorbing rate increases from industrial customers like tech companies.

As temperatures get hotter, there is no doubt our energy bills will go up. However, we must do everything we can to prevent massive projects from raising our bills even more. Investing in energy-draining artificial intelligence data centers not only increases electric rates for everyone, it takes away valuable jobs for rural communities. It’s time to invest in people over profits in North Carolina!

Massachusetts awards $53 million to help affordable housing operators cut emissions and make homes healthier https://energynews.us/2024/08/02/massachusetts-awards-53-million-to-help-affordable-housing-operators-cut-emissions-and-make-homes-healthier/ Fri, 02 Aug 2024 09:59:00 +0000 https://energynews.us/?p=2313740 A view of downtown Boston.

The latest round of grants will improve insulation and electrify heating and cooling systems as the state aims for net-zero emissions by 2050.

A view of downtown Boston.

Massachusetts has awarded $53 million — and announced plans for additional funding — to allow affordable housing operators to execute energy efficiency retrofits that are expected to reduce carbon emissions, cut energy bills, and create healthier, more comfortable homes for residents. 

The state in late July announced the second round of awards in the Affordable Housing Decarbonization Grant Program, allocating $26.1 million to five organizations to improve insulation, tighten building envelopes, and switch to heat pump heating and cooling systems. These grants come seven months after an initial round of $27.4 million was awarded to seven affordable housing operators statewide. 

“This has been a really critical funding stream for moving forward critical energy projects at some of our family public housing sites,” said Joel Wool, deputy administrator for sustainability and capital transformation at the Boston Housing Authority, which received grants in both rounds.

Along with the most recent round of awards, the state also announced it would invest another $40 million into the program in anticipation of giving out another set of grants in the fall.

The program was designed to address two major policy goals: decarbonization and addressing the state’s affordable housing crisis. 

Massachusetts has set the ambitious goal of going carbon-neutral by 2050. Buildings — which contribute 35% of the state’s carbon emissions — are a particularly important sector to target for decarbonization. This means finding ways to retrofit the state’s existing housing stock, much of which is drafty, heated by fossil fuels, and decades — or even centuries — old. 

At the same time, Massachusetts is experiencing an acute housing crisis. State officials estimate at least 200,000 new homes are needed to accommodate demand by 2030. Finding an affordable home is even more challenging for lower-income residents faced with soaring rents and home prices — and often, high energy bills. 

“We have such a housing crisis in Massachusetts that we want to do anything we can to create more housing, but also to make the housing we have now a better place to live,” said state Energy Department Commissioner Elizabeth Mahony. “These are investments in our infrastructure.”

Nonprofit Worcester Common Ground received an $820,000 grant in the latest round that it will use to complete deep energy retrofits on four buildings that were last updated some 30 years ago. The money will allow the renovations to include air sealing, more energy-efficient windows, and extra insulation. The grant will also allow the buildings to go fully electric, including with air source heat pumps that will provide lower-cost, more comfortable heating and cooling.

“Even though it’s a higher upfront cost, the hope is that maybe it reduces expenses going forward,” said Timothy Gilbert, project manager for Worcester Common Ground. “It might sound a little cheesy but we really do care about the well-being of the folks who live in our houses.”

In most cases, the grant money is being combined with other funding to allow more complete — and even downright ambitious — upgrades. In Worcester, other funding sources will pay for rooftop solar panels that will make the newly energy-efficient buildings even more cost-effective and environmentally friendly. The Boston Housing Authority is using its latest $5.8 million award as part of a larger project that aims to completely decarbonize the Franklin Fields housing development in the Dorchester neighborhood by combining energy efficiency upgrades and Boston’s first networked geothermal system. 

In the Boston neighborhood of Roxbury, the Madison Park Development Corporation is receiving $13.5 million from the Affordable Housing Decarbonization Grant Program to do work at its 331-unit Orchard Gardens development. But it is also seeking out other sources to meet the $20 million expected cost of the planned sustainability upgrades.

“It’s a big property and the heart of one of Boston’s oldest, most diverse, most underserved neighborhoods,” said Oren Richkin, senior project manager for the organization. “This grant money is pivotal for this project.”

Supporters of the program are expecting it to strengthen the state’s ability to respond to climate change in the future as well. Switching affordable housing units from fossil fuel heating to heat pump heating and cooling will allow residents to stay comfortable and safe in their own homes during increasingly hot summers, Wool said. 

The funding could also help nudge the ideas of deep energy retrofits and electrification more into the mainstream, Mahony said. 

“We are essentially socializing these programs — the more we do it, the more people will get used to the ideas,” she said. 

As the recipients of the first round of grants begin their projects, the state is starting to learn how to operate the program more effectively. The state has already, for example, started providing some technical assistance to organizations interested in applying for future rounds of funding. Continued conversations with building owners and nonprofits will be essential to creating an even stronger program moving forward, Mahony said.

“We’re setting ourselves up for success in the future,” she said.

Federal clean energy program unlocks benefits for Wisconsin schools https://energynews.us/2024/06/24/federal-clean-energy-program-unlocks-benefits-for-wisconsin-schools/ Mon, 24 Jun 2024 09:55:00 +0000 https://energynews.us/?p=2312631

Efficiency upgrade funding from the Inflation Reduction Act will help schools that have had to skip improvements amid budget cuts.

Along with new tax breaks for families and businesses in return for investing in clean and more efficient energy, the federal government is for the first time offering support to schools and other nonprofits that make those investments.

“Direct support” payments from the Internal Revenue Service will pay back school districts, churches and other nonprofit organizations for part of what they spend on energy renovations that cut their energy use and replace fossil fuels.

For schools the program represents an opportunity to make energy upgrades that many have had to skimp on, according to Nathan Ugoretz, secretary-treasurer of the Wisconsin Education Association Council.

As state school funding falls behind the rising costs public school districts face, “funding for maintenance and improvements have been put on the chopping block,” Ugoretz said Thursday. School districts across Wisconsin have held referendum votes to raise property taxes to support ongoing expenses.

“This leaves no resources for overhauling outdated electrical systems or investments to cut energy costs,” Ugoretz said.

Ugoretz spoke at Forest Edge Elementary School, a Fitchburg school that has been singled out for its strides in improving energy efficiency. In 2021, the school, after operating for just one year, was recognized as the first Net Zero Energy school in Wisconsin — producing and returning to the power grid as much energy as it used.

The BlueGreen Alliance, an advocacy group that combines the interests of the labor and environmental movements, chose the school Thursday for a presentation on how clean energy and energy efficiency tax credits under the 2022 Inflation Reduction Act are available to more than just taxpayers, whether individuals or businesses.

Direct IRS support that passes those tax credits on to nonprofits will help accelerate the spread of green technology to more users, participants in Thursday’s event said.

“That is a really, really big deal — not only because we get to model for our students what a clean energy economy looks like, but because utility costs for schools are one of the biggest demands on school budgets,” said Kristina Costa, deputy assistant to President Joe Biden for clean energy innovation and implementation. “And when energy costs go up, that leaves fewer resources available for everything else that students need to do.”

Cutting those costs by boosting energy efficiency “frees up those precious dollars to improve our schools and in other ways to enrich our kids’ education,” Costa added.

Spurred by the Inflation Reduction Act, businesses have invested $1.7 billion on clean power projects in Wisconsin through May 2024, according to the White House.

“This is a win, win, win,” said Rep. Mark Pocan (D-Town of Vermont) — for improving education resources, for labor and “more professional job development to have good wages and benefits. Pocan praised the Biden administration for taking  “the high road,” adding, “it’s a win for the environment because ultimately we’re addressing climate change through addressing the rising cost of energy.”

Forest Edge school was built well before the Inflation Reduction Act was signed into law, but as Wisconsin’s first net-zero energy school, “it’s an example of what’s possible for schools across the state,” state Carly Eaton, Wisconsin policy manager for BlueGreen Alliance.

From the start the Oregon School District facility was developed to be as energy efficient and clean-energy focused as possible, school district officials said.

A total of 1,704 solar panels line the flat rooftops of the building, providing enough electricity that the district is able to sell some of it back to the power grid, according to Andy Weiland, Oregon School District business manager. Walls of glass maximize natural light in the building, while the panes are specially treated to darken automatically in sunlight to prevent the building interior from heating up.

Geothermal energy, which draws heat from deep below the earth’s surface,  and heat pump technology warm the school — and also keep it cool when the weather outside is warm.

“For the most part we don’t have to use any fossil fuels at all,” Weiland said as he gave a tour of the building Thursday.

Had the district been able to use the Inflation Reduction Act’s direct support program when it was building the school, the savings, Weiland speculated, “would have been several million dollars.”

Beyond the savings that the act promises for people and organizations that use its incentives to upgrade their energy systems, the legislation has also been championed for provisions that require contractors to pay employees prevailing local wages on projects that qualify for the full values of tax credits. It also requires projects to employ participants in licensed apprenticeship programs.

The two requirements help stabilize the construction workforce, said Emily Pritzkow, executive director of the Wisconsin Building Trades Council, which represents about 40,000 Wisconsin members in several construction unions.

“By utilizing competitive labor standards, including an area’s standard wages, benefits and training opportunities, we are ensuring the economic impact of these projects stays in our local community for generations to come,” Pritzkow said.

Study: Vermont’s warming winters ‘not the whole story’ for declining fossil fuel use https://energynews.us/2024/06/18/study-vermonts-warming-winters-not-the-whole-story-for-declining-fossil-fuel-use/ Tue, 18 Jun 2024 09:59:00 +0000 https://energynews.us/?p=2312492 A large red barn sits in a golden field streaked with just a bit of snow

The analysis finds that warming winters explain most but not all of Vermont’s drop in fossil fuel sales, as improvements like heat pumps and weatherization are starting to have a greater impact.

A large red barn sits in a golden field streaked with just a bit of snow

A new analysis says Vermont is not on track to meet its 2025 target for reducing greenhouse gas emissions, with declines in thermal fossil fuel use driven mostly — though not entirely — by warming winters. 

The study, released last month by the Vermont nonprofit Energy Action Network, also shows signs of progress: Though rising temperatures are still the main driver of lower heating fuel sales, weatherization and electric heat pump adoption are starting to have a greater impact.

“Vermont’s efforts… are, ironically, being aided by the very global heating that we are working to do our part to help minimize,” the study says. “Relying on warmer winters to reduce emissions from fossil heating fuel use is not a sustainable strategy. … What [the warming trend] means for temperatures — and therefore fuel use — in any given year is still subject to variation and unpredictability.”

Like most other New England states, Vermont relies heavily on heating oil and, to a lesser degree, propane and utility gas, to heat buildings. This makes the building sector a close second to transportation in terms of the biggest contributors to planet-warming emissions in Vermont and many of its neighbors. 

Vermont’s statutory climate targets, adopted in 2020, aim to cut these emissions by 26% below 2005 levels by next year, with higher targets in the coming decades.

“It’s technically possible” that Vermont will meet its thermal emissions goal for next year, but “at this point, primarily dependent on how warm or cold the fall and early winter heating season is at the end of 2024,” EAN executive director Jared Duval said. The transportation sector would need to see a nearly unprecedented one-year decline.

On the whole, EAN says it’s “exceedingly unlikely” that Vermont will meet its 2025 goal. 

Warmer winters ‘not the whole story’

EAN found that heat pump adoption and weatherization are not happening fast enough, and what’s more, the current trend sets Vermont up for a Pyrrhic victory at best: Rising temperatures in the upcoming heating season would have to be at least as pronounced as in last year’s record-warm winter in order to reduce fuel use enough to meet the 2025 target for the thermal sector. 

Either way, warming alone won’t get Vermont to its 2030 target of a 40% drop in emissions over 1990 levels, Duval said. The state wants to end up at an 80% reduction by 2050. 

“The only durable way to reduce emissions in line with our science-based commitments is to increase the scale and pace of non-fossil fuel heating solutions and transportation solutions,” he said.

The EAN study found that fuel sales tend to decline alongside heating degree days: a measurement of days when it’s cold enough to kick on the heat. Vermont is seeing fewer of these days overall as temperatures warm. 

“The reduction in fossil heating fuel sales as winters have been warming is not surprising,” Duval said. “Historically, fossil heating fuel use and therefore greenhouse gas emissions have largely tracked with heating demand, with warmer winters corresponding with less fossil fuel use and colder winters with more fossil fuel use. The good news is that’s not the whole story.”

In recent years, he said, fuel sales have begun to “decouple” from the warming trend to which they were once more closely linked. From 2018 to 2023, EAN found that Vermont fuel sales declined 12% while heating degree days only declined 8%.

“Fossil heating fuel sales are declining even more than you would expect just from warmer winters alone,” Duval said. “And that’s because many non-fossil fuel heating solutions are being adopted.” 

Upgrades needed to accelerate progress

From 2018 to 2022, EAN found, Vermont saw a 34% increase in weatherization projects and more than 50,000 more cold-climate heat pumps installed in homes and businesses, with a 3.3% increase in the number of homes that said they use electricity as their primary heating fuel. 

The upshot: The number of cold days explains 50% of Vermont’s declining fuel use from 2018 to 2023, while heat pump growth explains as much as 28% and other efficient upgrades explain a further 15%. The remaining 7% of the decline couldn’t easily be broken down and could partly be from people shifting to wood heat during periods of high fuel prices, Duval said.

“In order to achieve thermal sector emissions reduction targets without relying primarily on an abnormal amount of winter warming, significantly more displacement and/or replacement of fossil heating fuel… will be necessary,” the study says. Upgrades like heat pumps will lead to more sustainable emissions cuts, it says, “no matter what the weather-dependent heating needs in Vermont will be going forward.” 

EAN is nonpartisan and doesn’t take policy positions, but research analyst Lena Stier said this data suggests that expanding Vermont’s energy workforce and tackling heat pumps and weatherization in tandem would spur faster progress on emissions cuts, while keeping costs low.

EAN based its estimates of fuel use and emissions impacts from heat pumps on the official assumptions of a state-approved technical manual, which Duval said may be overly optimistic. But Stier said the reality could differ.

“We’ve heard anecdotally that a lot of people who have installed heat pumps in their homes… are kind of primarily using them for cooling in the summer,” she said. “So our kind of assumption is that, in reality, it would be a smaller share of that (fossil fuel use) reduction coming from heat pumps.” 

While fuel use declined overall in the study period, he said this came mostly from people using less heating oil specifically — propane sales actually increased in the same period.

Duval noted that propane is cheaper than oil on paper, but actually costs more to use because it generates heat less efficiently than oil does. 

“Once you look at that, then heat pumps become that much more attractive,” he said.
