The most cost-effective energy efficiency investments you can make — and how the new Inflation Reduction Act could help

Jasmina Burek, The Conversation • November 8, 2022

Energy efficiency can save homeowners and renters hundreds of dollars a year, and the new Inflation Reduction Act includes a wealth of home improvement rebates and tax incentives to help Americans secure those saving.

It extends tax credits for installing energy-efficient windows, doors, insulation, water heaters, furnaces, air conditioners or heat pumps, as well as for home energy audits. It also offers rebates for low- and moderate-income households ’ efficiency improvements, up to US$14,000 per home.

Together, these incentives aim to cut energy costs for consumers who use them by $500 to $1,000 per year and reduce the nation’s climate-warming greenhouse gas emissions.

With so many options, what are the most cost-effective moves homeowners and renters can make?

My lab at UMass Lowell works on ways to improve sustainability in buildings and homes by finding cost-effective design solutions to decrease their energy demand and carbon footprint. There are two key ways to cut energy use: energy-efficient upgrades and behavior change. Each has clear winners.

Stop the leaks

The biggest payoff for both saving money and reducing emissions is weatherizing the home to stop leaks. Losing cool air in summer and warm air in winter means heating and cooling systems run more, and they’re among the most energy-intensive systems in a home.

Gaps along the baseboard where the wall meets the floor and at windows, doors, pipes, fireplace dampers and electrical outlets are all prime spots for drafts. Fixing those leaks can cut a home’s entire energy use by about 6%, on average, by our estimates. And it’s cheap, since those fixes mostly involve caulk and weather stripping.

The Inflation Reduction Act offers homeowners a hand. It includes a $150 rebate to help pay for a home energy audit that can locate leaks.

While a professional audit can help, it isn’t essential – the Department of Energy website offers guidance for doing your own inspection.

Once you find the leaks, the act includes 30% tax credits with a maximum of $1,200 a year for basic weatherization work, plus rebates up to $1,600 for low- and moderate-income homeowners earning less than 150% of the local median.

Replace windows

Replacing windows is more expensive upfront but can save a lot of money on energy costs. Leaky windows and doors are responsible for 25% to 30% of residential heating and cooling costs , according to Department of Energy estimates.

Insulation can also reduce energy loss. But with the exception of older homes with poor insulation and homes facing extreme temperatures, it generally doesn’t have as high of a payoff in whole-house energy savings as weatherization or window replacement.

The Inflation Reduction Act includes up to $600 to help pay for window replacement and $250 to replace an exterior door.

Upgrade appliances, especially HVAC and dryers

Buildings cumulatively are responsible for about 40% of U.S. energy consumption and associated greenhouse gas emissions, and a significant share of that is in homes. Heating is typically the main energy use.

Among appliances, upgrading air conditioners and clothes dryers results in the largest environmental and cost benefits; however, HVAC systems – heating, ventilation and air conditioning – come with some of the highest upfront costs.

That includes energy-efficient electric heat pumps , which both heat and cool a home. The Inflation Reduction Act offers a 30% tax credit up to $2,000 available to anyone who purchases and installs a heat pump, in addition to rebates of up to $8,000 for low- and moderate-income households earning less than 150% of the local median income. Some high-efficiency wood-burning stoves also qualify.

The act also provides rebates for low- and moderate-income households for electric stoves of up to $840, heat-pump water heaters of up to $1,750 and heat-pump clothes dryers of up to $840.

Change your behavior in a few easy steps

You can also make a pretty big difference without federal incentives by changing your habits. My dad was energy-efficient before it was hip. His “hobby” was to turn off the lights. This action itself has been among the most cost-saving behavioral changes.

Just turning out the lights for an hour a day can save a home up to $65 per year. Replacing old lightbulbs with LED lighting also cuts energy use. They’re more expensive, but they save money on energy costs.

We found that a homeowner could save $265 per year and reduce emissions even more by adopting a few behavioral changes including unplugging appliances not being used, line-drying clothes, lowering the water heater temperature, setting the thermostat 1 degree warmer at night in summer or 1 degree cooler in winter, turning off lights for an hour a day, and going tech-free for an hour a day.

Some appliances are energy vampires – they draw electricity when plugged in even if you’re not using them. One study in Northern California found that plugged-in devices, such as TVs, cable boxes, computers and smart appliances, that weren’t being used were responsible for as much as 23% of electricity consumption in homes.

Start with a passive solar home

If you’re looking for a home to rent or buy, or even to build, you can make an even bigger difference by looking at how it’s built and powered.

Passive solar homes take advantage of local climate and site conditions, such as having lots of south-facing windows to capture solar energy during cool months to reduce home energy use as much as possible. Then they meet the remaining energy demand with on-site solar energy.

Studies show that for homeowners in cold climates, building a passive design home could cut their energy cost by 14% compared with an average home. That’s before taking solar panels into account.

The Inflation Reduction Act offers a 30% tax credit for rooftop solar and geothermal heating, plus accompanying battery storage, as well as incentives for community solar – larger solar systems owned by several homeowners. It also includes a $5,000 tax credit for developers to build homes to the Energy Department’s Zero Energy Ready Homes standard.

The entire energy and climate package – including incentives for utility-scale renewable energy, carbon capture and electric vehicles – could have a big impact for homeowners’ energy costs and the climate. According to several estimates , it has the potential to reduce U.S. carbon emissions by about 40% by the end of this decade.The Conversation

Common Sense for the Eastern Shore

US Wind, Oceantic Pitch Offshore Wind Future Amid Trump Attacks

By Jan Plotczyk • September 10, 2025
 At Shore Progress’s monthly meeting last week, the tension between national politics and local opportunity was on full display. With President Donald Trump escalating his attacks on offshore wind, representatives from US Wind and the Oceantic Network made their case directly to members gathered in Salisbury. From the outset, the presenters stressed the scale of what’s coming to the Eastern Shore. “This project is the equivalent of building two nuclear power plants off our coast,” US Wind representative Dave Wilson said, pointing to plans for 114 turbines and four offshore substations. Together, he said, the project will generate two net gigawatts of clean energy, enough to power approximately 26% of the homes in Maryland. The presentation walked members through the timeline: a four-phase buildout beginning in the southeast corner of the lease area, with each phase, including its own export cable, routed through Indian River Bay into the regional grid at the Indian River Power Plant in Delaware. Environmental safeguards on display Slides showed how US Wind plans to minimize negative effects on wildlife. The company will use an aircraft detection lighting system to keep turbines dark until a low-flying aircraft approaches, reducing night-sky light pollution. Marine protections include bubble curtains to dampen noise during pile driving, visual and acoustic monitoring for whales, and strict shutdown zones if animals enter construction areas. Lights will be on less than 1% of the time in any given year, underscoring their view that offshore wind can coexist with migratory birds, commercial fishing, and marine transit. Economic promise for the Shore The discussion turned quickly to what the project means locally. US Wind pledged hundreds of jobs for the Shore, with commitments to use union labor and partner with minority, women, and veteran-owned businesses. Officials noted that the Lower Shore Workforce Alliance has already received $700,000 from Maryland Works for Wind to build training programs, while community colleges are adjusting trade curricula to educate the next generation of turbine technicians. A planned operations and maintenance facility in West Ocean City will house technicians and crew transfer vessels, bringing steady employment and infrastructure investment to the harbor. A national fight with local stakes The meeting didn’t shy away from politics. Several members noted Trump’s repeated attempts to derail offshore wind projects including his latest push to revoke US Wind’s federal permit. US Wind officials acknowledged that such lawsuits could delay progress but insisted that the project’s federal approvals are on solid ground. “This is the Eastern Shore's moment,” Shore Progress Chair Jared Schablein said, referring to a slide that showed more than $815 million in offshore wind investments statewide. “The question is whether politics will slow us down, or whether we keep building for the Shore’s future.” The presentation had a clear message: Offshore wind is not just about clean power, but also about jobs, investment, and opportunity for Eastern Shore families.

Gov. Moore Signs “Housing Starts Here” Order to Tackle Maryland’s Affordability Crisis

By Gren Whitman • September 10, 2025
Standing at the Legacy at Twin Rivers apartment community in Howard County, Maryland Gov. Wes Moore signed an executive order aimed at addressing his state’s deepening housing crisis. Titled Housing Starts Here, his order is designed to accelerate construction of affordable homes and cut through what Moore called years of “no and slow” decision-making in state housing policy. Maryland is facing a shortage of at least 96,000 housing units, according to state estimates, a gap that officials say has driven up prices, pushed families out of the state, and stifled economic growth. “Building pathways to wealth for Marylanders, creating jobs, attracting new businesses and residents, growing our economy, and securing our future all start with housing,” Moore said at the signing. “We need to be the state of yes and now.” Five guiding principles The executive order lays out five core priorities for state housing policy: Use state land for housing . Agencies must identify surplus properties and land near transit stations that can be converted into new housing developments. Cut red tape. State permitting processes will be streamlined, with new rules allowing third-party reviewers to accelerate approvals. Strengthen partnerships. A new State Housing Ombudsman will serve as a liaison to help coordinate projects between state agencies, local governments, and developers. Set clear goals. By January 2026, the state will publish housing production targets for each county and update them every five years. Incentivize affordable housing. Jurisdictions that meet housing targets or pass pro-housing policies will be recognized with new Maryland Housing Leadership Awards, making them more competitive for state funding. Speed as the priority State officials said the new framework is focused on cutting delays that can hold back projects for years. By digitizing applications, engaging multiple agencies simultaneously, and allowing outside reviewers, the state aims to expedite project completion while upholding environmental and community standards. What could this mean for us on the Eastern Shore? Moore acknowledged that housing affordability consistently ranks as Marylanders’ No. 1 concern. For young people in particular, high costs and long commutes are major reasons they leave the state. The order seeks to reverse that trend, tying housing growth to job creation and transit access. On the Eastern Shore , where rental availability and starter homes are limited, Moore’s order could open opportunities for mixed-use, transit-oriented projects on state-owned land, as well as accelerate approval for affordable housing initiatives backed by nonprofits and local developers. What comes next The Department of Housing and Community Development will publish the state’s first set of production targets by Jan. 1, 2026, followed by annual progress reports starting in 2027. Agencies have until March 2026 to implement many of the new permitting and funding acceleration rules. Moore framed the executive order as a generational investment. “Making housing more affordable is not just about building shelter, it’s about building a legacy,” he said.

Alsobrooks Leads Push to Remove RFK Jr. From HHS, Citing “Costs, Chaos, and Corruption”

By Gren Whitman • September 10, 2025
Sen. Angela Alsobrooks (D-Md.) has intensified her calls for Health and Human Services Secretary Robert F. Kennedy Jr. to step down, releasing a detailed report that she says proves his tenure has been a disaster for American families. The first senator to demand Kennedy’s resignation in May, Alsobrooks joined Senate Finance Committee Ranking Member Ron Wyden (D-Ore.) in unveiling a 54-page report that chronicles what they describe as the “costly, chaotic, and corrupt” record of Kennedy’s first 203 days at the department. Released before Kennedy’s Senate hearing last week, the report outlines examples of alleged mismanagement for each day since he was sworn in on Feb. 13. “Robert Kennedy’s tenure as America’s chief health officer has been higher costs, more chaos, and boundless corruption,” Wyden said. “His actions are endangering children, leaving parents confused and scared, and forcing families and taxpayers to pay more for their health care.” Echoing that assessment, Alsobrooks cited testimony from scientists at the National Institutes of Health in Maryland who she says have watched critical cancer research grind to a halt under Kennedy’s leadership. “His actions are increasing Americans’ health care costs, causing chaos, and furthering the Trump administration’s endless stream of corruption,” she said. The report argues that Kennedy has: Driven up costs by backing the Trump administration’s budget plan, which Alsobrooks says strips health coverage from 15 million Americans while handing tax breaks to the wealthy and corporations. Created chaos by dismantling HHS programs, undermining research institutions, and promoting vaccine misinformation. Engaged in corruption by using the office to advance personal and family financial interests, particularly around limiting vaccine access. Public Citizen, a consumer advocacy group, praised Alsobrooks’ leadership. “President Trump and Senate Republicans made a grievous error when entrusting Kennedy with our nation’s health,” the group said in. “It is far past time that President Trump rectifies this error by firing Kennedy before more lives are unnecessarily put at risk.” Alsobrooks appeared on the Morning Joe TV show on to discuss the findings and to reiterate her demand that Kennedy resign or be removed. “This is about protecting families and protecting science,” she said. “Our nation’s health system cannot afford another day under Robert Kennedy’s reckless watch.” As a community organizer, journalist, administrator, project planner/manager, and consultant, Gren Whitman has led neighborhood, umbrella, public interest, and political committees and groups, and worked for civil rights and anti-war organizations.

Wicomico Officials Advance ICE Partnership Amid Community Opposition and Rising Concerns

By CSES Staff • September 10, 2025
Wicomico County leaders have announced plans to move forward with the federal government’s controversial 287(g) program, entering into an agreement with U.S. Immigration and Customs Enforcement (ICE) that would deputize local officers to serve immigration warrants inside the county jail. Under the model selected, known as the Warrant Service Officer program, specially trained deputies at the detention center would be allowed to serve civil immigration warrants on individuals already in custody. County Executive Julie Giordano and Sheriff Mike Lewis emphasized that deputies would not conduct street-level immigration enforcement. “Public safety is our top responsibility,” Giordano said. “The Warrant Service Officer program provides our sheriff’s office with the tools they need to address individuals already in custody who may pose a risk to our community at no additional cost to the county.” Lewis added that the program “gives our deputies the ability to safely and lawfully carry out their duties while ensuring that Wicomico County remains a secure place to live, work, and raise a family.” Community pushback The announcement drew swift opposition from civil rights and community organizations, including the ACLU of Maryland, the Wicomico NAACP, and local grassroots groups such as Crabs on the Shore, who have warned that the agreement will harm immigrant families, sow fear, and erode trust between residents and law enforcement. Opponents also criticized the process, arguing that the decision was rushed through without meaningful public input despite repeated calls for hearings. “This is being framed as an administrative detail, but it has huge consequences for our neighbors,” one advocate said. Concerns about cost and precedent Supporters of the WSO model have emphasized that the partnership comes “at no additional cost” to Wicomico taxpayers, but critics point out that other jurisdictions have found otherwise. Anne Arundel County canceled its own 287(g) agreement, citing high costs and community backlash. The Camden Police Department in Delaware withdrew from a similar partnership after public protests in May. Advocates note that the federal government does not fully reimburse counties for the time, training, and legal exposure associated with 287(g) programs, leaving local taxpayers to shoulder hidden expenses. First on Delmarva If finalized, Wicomico County would become the first government or police agency on the Delmarva Peninsula to formally enter into a 287(g) agreement with ICE. Supporters say that distinction demonstrates a commitment to accountability and public safety. Opponents warn it risks branding the county as hostile to immigrant communities that have long been central to the Shore’s workforce, particularly in poultry processing and agriculture. The county’s decision comes amid a broader national debate about local involvement in federal immigration enforcement, with critics warning that partnerships like 287(g) make communities less safe by discouraging victims and witnesses from coming forward. For now, the final agreement is pending federal approval. But with strong opposition already mobilized, the fight over Wicomico’s new partnership is likely only beginning.

Wicomico Democrats Silent as County Leaders Advance ICE Agreement

By CSES Staff • September 10, 2025
Wicomico County Republicans have moved forward with an agreement to join the federal 287(g) program, aligning the county with the U.S. Immigration and Customs Enforcement (ICE). County Executive Julie Giordano and Sheriff Mike Lewis are backing the program to train county officers at the detention center to help ICE identify non-citizens for deportation proceedings. The agreement has triggered strong pushback from immigrant advocates, civil rights groups, and community leaders who warn that this partnership will erode trust between residents and law enforcement, risk racial profiling, and allot local tax dollars to assist federal immigration enforcement. Yet amid the growing controversy, the Wicomico County Democratic Central Committee has issued no response to the ICE agreement, even as residents voice frustration that the Democratic establishment’s silence has ceded the conversation to Republicans. Moreover, the Central Committee has remained silent with regard to recent comments by Democratic Councilwoman April Jackson, who told the Washington Post that the poultry industry should reduce its reliance on immigrant workers. Jackson also said, “a lot of Americans aren’t employed because the Haitians are taking our jobs.” Jackson’s remarks have drawn widespread criticism from immigrant advocates. For many residents, the Democratic leadership’s silence is as much of a concern as the county government’s new partnership with ICE. As the county waits for federal approval of the 287(g) agreement, the absence of a Democratic counterweight has left immigrant families and community organizers to carry the opposition on their own.
