Each year, about 50,000 new homes are sold in Colorado, and more than half of these are single-family homes. Most of these new homes continue to rely on natural gas for heating, and are generally built to the minimum efficiency standards of the local building code. This status quo aspect of the new homes market only exacerbates the climate crisis. Although a modest trend at this point, some builders and developers are building new homes that are more energy-efficient, with better indoor air... More

Last month, Colorado’s transportation planning agencies officially updated their plans and project lists to meet the Colorado Department of Transportation's (CDOT) new greenhouse gas (GHG) reduction targets. The new plans spend significantly less money on highway expansions and redirect billions of dollars toward multimodal projects like transit, biking, and walking infrastructure to make these low-carbon transportation options more convenient, safe, and affordable for Coloradans. By giving... More

Tomorrow, October 5, is Energy Efficiency Day. Want to celebrate by doing something impactful to decrease your home’s energy use and carbon emissions while saving money in the process? Pledge to make your next air conditioner (AC) a heat pump. Many homeowners are already aware of the benefits of installing more efficient LED light bulbs, or of a programmable thermostat that adjusts the air-conditioning or heating when nobody is home. With the recent passage of the Inflation Reduction Act... More

Now that the Southwest state legislatures have adjourned, it’s time to recap our progress and look to opportunities in 2023. Despite challenges posed by the lingering COVID pandemic and growing inflation, we’re proud to report numerous significant wins achieved in legislative chambers led by both Republicans and Democrats across the region. Here are some of the key legislative gains in efficiency and clean transportation from around the Southwest in 2022: Colorado had another banner... More

When we burn gas to keep our homes warm and heat our hot water, or burn gasoline to power our cars, most of us don’t think about how these fuels are produced or the additional emissions involved in the “upstream” oil and gas production. But the upstream carbon pollutant emissions are significant, and there are ways to reduce and minimize them. Colorado and New Mexico are two of the leading states in oil and gas production, and carbon emissions from oil and gas production accounts for more... More

We at the Southwest Energy Efficiency Project (SWEEP) join the loud chorus of voices across the country opposing the United States Supreme Court’s June 30th decision in the West Virginia v. EPA climate case as both illogical and ill-advised. The high court chose to hamstring the Biden Administration’s efforts to meet our climate goals. The majority turned its back on the wishes of the American people, the overwhelming majority of whom support more aggressive national action to reduce... More

Although there may be supply chain constraints on some heat pump products, new rebates and tax incentives make this year — or next — an excellent time for homeowners to consider adding a new heat pump. Heat pumps are very similar to central air conditioning (AC) systems, but they have a reversible valve that allows them to provide both heating and cooling. Because Colorado’s electricity is becoming more and more renewable-based, heat pumps significantly reduce the home’s carbon emissions... More

If you are looking for a way to reduce your personal contributions to carbon emissions, a good place to start is switching to an efficient electric heat pump to heat and cool your home. For homes in Utah, this will have about the same impact as switching your car (or truck) to an electric vehicle. The Southwest Energy Efficiency Project (SWEEP) just released an updated study of the benefits of heat pumps and heat pump water heaters (HPWHs) for Southwest homes, about 65% of which currently...

The Southwest Energy Efficiency Project just released an updated study of the benefits of heat pumps and heat pump water heaters (HPWHs) for Southwest homes, about 65% of which currently use gas for heating. Gas prices have increased significantly in the last six months, and as a result heat pumps and HPWHs are now much more cost-effective than they were one or two years ago. In addition, heat pump and HPWH performance and availability have continued to improve. For homes in Las Vegas and... More

If you are looking for a way to reduce your personal contributions to carbon emissions, a good place to start is switching to an efficient electric heat pump to heat and cool your home. For Arizonans, this also reduces the home’s annual heating costs by about 40%. The Southwest Energy Efficiency Project just released an updated study of the benefits of heat pumps and heat pump water heaters (HPWHs) for Southwest homes, about 65% of which currently use gas for heating. Gas prices have... More

Fly into Denver International Airport (DIA) in the daylight and you can look down on acres of open land being groomed for sprawling single-family development. In 2021, over ¾ of lots under development in the Denver region were in Adams, Arapahoe, and Douglas Counties, mostly single-detached homes built on undeveloped land far from jobs, shopping, and other destinations. This type of low-density, auto-centric growth is incompatible with Colorado’s air quality and climate goals, and will only... More

In response to devastating wildfires in Colorado and other climate change-driven extreme weather around the county, more and more Coloradans are asking, “what can we do to reduce our carbon footprint?” A good place to start is switching to an efficient electric heat pump to heat and cool the home. This switch would have a similar impact to switching from a gasoline-powered car or truck to an electric vehicle. The Southwest Energy Efficiency Project (SWEEP) just released an updated study of...

Energy efficiency is also an economic engine, amassing a U.S. workforce of nearly 2.4 million by the beginning of this... More

These are challenging times for Arizona. Record drought has caused another horrendous wildfire season and another summer of scorching temperatures and record heatwaves from Phoenix to Tucson. It’s also triggered the unprecedented decision to cut back Arizona’s share of water from the Colorado River, which will significantly impact our state’s hard-working farmers. In addition, intense heat exacerbates air quality problems, resulting in dozens of ozone alerts this summer and signaling unhealthy... More

Now that the 2021 legislative sessions have gaveled to a close in state capitals across the Southwest, it’s time to celebrate what we accomplished on energy efficiency and clean transportation. While most eyes were on the new leadership in Washington, D.C., important progress was being made in both Democrat- and Republican-led legislative chambers throughout the region. These successes came in the form of bills to eliminate wasteful energy use, cut air pollution and climate altering emissions,... More

The Colorado legislature adopted a wide range of new policies to advance clean energy and cut greenhouse gas (GHG) emissions in its recently concluded 2021 session. In addition to approving new policies to lower GHG emissions in the utility, transportation and oil and gas sectors, the legislature approved several innovative policies that will increase energy efficiency and decarbonize energy use in Colorado’s buildings. Here’s a summary of these new policies. SB21-246 advances... More

This week, Colorado Governor Jared Polis signed Senate Bill 260 (SB260) into law, marking the passage of the most comprehensive transportation funding package in decades. The legislation will raise $5.4 billion over the next 10 years through a combination of general fund transfers and new fees on gasoline, diesel, electric vehicles (EVs), residential deliveries, and rideshare trips to repair and expand our decaying transportation system and clean up its air pollution. While not perfect, the ... More

We surveyed builders from across Colorado to uncover examples of new, all-electric homes — a trend far more common in other parts of the country, but finally gaining a foothold in southwestern climates thanks to some impressive technology advances. In SWEEP's recently-published fact sheet, we profiled 11 examples of all-electric construction either recently built or underway — including large master-planned developments, custom-built single-family homes, multifamily buildings, and a pre-K-12...

The Southwest Energy Efficiency Project (SWEEP) is disappointed in the 2021 New Mexico State Legislature’s failure to pass House Bill 206 (HB206), the Utility Affordability and Relief Act. Despite receiving full support of many lawmakers, the New Mexico Public Regulation Commission (PRC) Chair, low-income advocates, social justice organizations, and environmental groups, the Senate Finance Committee refused to hold a hearing on the bill. After passing two committees in the House, the House... More

There’s a critical need for additional housing in northern Nevada as the area sees rapid job growth associated with economic diversification. Charles Bluth, an entrepreneur who since 1969 has specialized in land acquisition and developments in California, Nevada, and Arizona, has helped respond to the local demand for multi-family housing with his 768-unit project, The Lakes at Lemmon Valley. This project notably avoids natural gas for space and water heating and cooking. Instead of fossil... More

After months of meetings, emails, articles, and hours of testimony and concerns voiced about the validity of a new concept, the International Code Council (ICC) Board has decided to move the International Energy Conservation Code (IECC) from the ICC code development process to the ICC standards development process. The concern with moving to the standards development process was the potential for the IECC to roll back progress made on efficiency, which would undermine states’ and municipal... More

Local governments around Colorado are making the GoEV City commitment — a pledge to electrify 100% of the cars, trucks, and buses in their communities over the next few decades.
