The national clean car standards, which limit tailpipe emissions from cars, represent one of the biggest steps the federal government ever has taken to reduce energy use and greenhouse gas emissions. The Obama administration adopted the clean air rules in 2012, when automakers agreed to a set of standards requiring them to gradually reduce pollution and improve fuel economy. Under this plan, by 2025 the average car would have about double the fuel economy and emit only about half the carbon... More

Download a PDF version of this article Every one of Colorado’s 333 local jurisdictions is responsible for adopting its own local building code. That diversity gives us a comprehensive picture of how energy codes are perceived, considered, adopted, amended, and enforced across different parts of the state, and how they change over time. Here are five trends we’ve seen shaping the status of our energy codes in Colorado so far in 2018. These themes appear in many other home-rule states, too, so ... More

Energy codes matter: In 2016, the residential and commercial sectors devoured about 40 percent of total U.S. energy consumption (or roughly 39 quadrillion British thermal units), the U.S. Energy Information Administration said in a May 2017 report. That voracious appetite can be reduced, though, if homes and commercial buildings include the latest efficiency technologies, such as “smart” thermostats, high-quality insulation, and advanced heating, ventilation, and cooling systems. Whether... More

The state of Colorado has just released a bold new electric vehicle plan that builds on the state’s work to date and shows the way to an electrified future. The plan (developed by the Colorado Energy Office, the Regional Air Quality Council, the Colorado Department of Public Health and Environment, and the Colorado Department of Transportation), was spurred by Governor Hickenlooper’s Executive Order from July of 2017, “Supporting Colorado’s Clean Energy Transition.” The plan lays out...

Indoor cannabis grow operations can be very energy intensive, using about ten times the amount of energy per square foot as a typical office building. In states where either medical or recreational cannabis is legal, utilities can achieve big energy savings by proactively engaging with these customers. SWEEP just released a new report on this topic, “A Budding Opportunity: Energy efficiency best practices for cannabis grow operations.” Three leading utilities in the Northwest are reaping... More

The buzz at the 2017 Solar Decathlon proved infectious, thanks to the human energy and excitement of the college students worldwide who participated in the October event in Denver. And as a professional in energy-efficient buildings, I was impressed by what the young people demonstrated: new concepts, some pretty amazing technology, well-designed and cool-looking houses, and their willingness to "stretch the envelope" (pun intended). The competition also gave me an opportunity to reflect on... More

Reno embraced Nevada’s newly re-invigorated push toward cleaner energy when the city launched REENERGIZE RENO, its ambitious program to improve the efficiency of municipal, commercial, industrial and multifamily buildings by 20 percent by 2025. The move shows how local governments, coupled with forward-looking state policies, can reduce pollution, conserve water, curb climate change, and create jobs even as they help consumers and businesses save money. REENERGIZE RENO is part of the U.S.... More

SWEEP’s full paper, reviewing the history and effects of these programs, can be read here. Some of the information deserves emphasis and is summarized in this blog. The fact sheets and paper demonstrate that electric utilities in the region have generated enormous... More

The Colorado Department of Public Health and the Environment (CDPHE) has released a draft plan on how the state will allocate approximately $70 million in funding that the state will receive as part of the settlement of the VW emissions cheating scandal. The settlement funds are designed to reduce air pollution from vehicles, in order to mitigate the effects of the non-compliant, diesel-fueled Volkswagens. During a 2016 public comment period, the public overwhelmingly told the department... More

Each year, the U.S. Department of Energy (DOE) recognizes the Zero Energy Ready Home (ZERH) program builders with the department’s Innovation in Housing Awards. Only the top 1 percent of builders in the nation receive these prestigious awards. But this year, builders from SWEEP states won the Innovation in Housing awards in four of the five categories: Affordable Home, Multi-Family Home, Production Home and Custom Home (Buyers). The Custom (Spec) category was the only housing category without a ... More

Federal energy efficiency programs within the U.S. Department of Energy (DOE) and Environmental Protection Agency (EPA) are threatened with devastating budget cuts proposed by the Trump Administration. Should citizens, businesses, and elected officials in the Southwest care? Absolutely! According to a 2017 DOE report, Southwestern states (AZ, CO, NM, NV, UT, and WY) are home to 123,000 energy efficiency jobs -- more jobs, in fact, than any other segment of the energy industry including oil... More

Colorado Governor John Hickenlooper signed an executive order on July 11, 2017, in which he pledged that Colorado would meet the Paris climate targets, and set goals for reducing emissions through more renewable energy, ramping up utility energy efficiency programs, making buildings greener, and accelerating the adoption of electric vehicles (EVs). In order to meet these emissions targets, the state will need to ramp up electric vehicle adoption, and do it fast. While the EV market in... More

Two of Colorado’s most important political leaders recently adopted plans that encourage greater adoption of electric vehicles (EVs), both as a strategy to help curb climate change and to improve the air that Denverites breath. Governor John Hickenlooper signed an executive order on climate that includes the development of a statewide EV plan, while Denver Mayor Michael Hancock released a Mobility Action Plan, which calls for multiple steps to encourage EV adoption. Now, a new report ... More

The Powder River Basin in Wyoming is the largest coal-producing region in the U.S. There are tens of thousands of oil and natural gas wells as well as over 1,900 wind turbines operating on the Eastern Plains of Colorado. Eastern New Mexico is a major oil and gas producing region, and large-scale solar power plants are sprouting up across the desert Southwest. But which segment of energy industry supports the most jobs in the energy-rich Southwest? Answer: It’s the energy efficiency industry, ... More

This Zero-Energy home in Durango, Colorado, keeps residents warm even in winter at an elevation of over 6,500 feet. More than 60 percent of the most energy-efficient homes built today in the country have been constructed in the Southwest. What’s more, nearly two-thirds of the homebuilders who make these highly efficient houses also are based in this region. The reasons for this success could serve as a model for other parts of the nation seeking to improve the efficiency and quality of... More

When President Donald Trump recently walked away from the Paris Climate Agreement, his decision spurred many states, cities and businesses nationwide to step up their own push to reduce greenhouse gas emissions, regardless of what the federal government does or doesn’t do. One key area for action is transforming America’s transportation systems. Cars and trucks are now the largest source of carbon pollution in the United States. Emissions from electricity generation are declining due to the... More

Colorado lawmakers are debating a proposal to eliminate tax credits that encourage consumers to buy cleaner, energy-efficient electric vehicles (EVs) and other alternative fuel vehicles. Opponents of the program, notably the Independence Institute and Americans for Prosperity, are feeding legislators incorrect information about how much most consumers can benefit from the program. Despite the opponents’ claims, EVs are not toys for the rich. More than three-quarters of EVs sold in Colorado have ... More

The best time to plan for an electric vehicle (EV) charging station is before most consumers even know that they will want one. Communities that require builders to install EV charging capabilities in new apartments, single-family homes and commercial offices will make the transition away from gasoline-powered cars easier for their residents. Moreover, these 21st Century building codes will encourage consumers to consider purchasing EVs and help the communities take an important step toward a... More

On the eve of Donald Trump's inauguration as 45th President, he has nominated Rex Tillerson as Secretary of State, Scott Pruitt as EPA Administrator, and Rick Perry as Energy Secretary. If the adage "personnel is policy" holds true, energy efficiency and clean energy will face a tough four years with respect to federal policy. While it's too early to know what specific actions the Trump Administration will take, it's reasonable to assume that the Clean Power Plan will fall by the wayside; use... More

What's the benefit to a local community of incorporating the newest energy efficiency measures into the building code? For one Colorado town, it’s already worth $1.2 million. The lessons from Parker (located southeast of Denver) underscore how local leaders can help their residents, businesses, homebuilders and commercial real estate developers recognize that spending a little money upfront can lead to big savings in the long run. Can your town, city or county show similar, positive results?... More

Salt Lake City is one of 19 cities that participated in the U.S. Department of Energy’s Energy Data Accelerator initiative, which tasked local governments to collaborate with their utilities to provide businesses with a whole-building, automated energy benchmarking program. The goal was to find a way to connect businesses’ utility accounts with building energy databases such as the nation’s most popular (and free) ENERGY STAR Portfolio Manager®. Salt Lake City and its partners were... More

The Environmental Protection Agency (EPA) included many references to energy efficiency as a strategy to achieve Clean Power Plan (CPP) compliance and encouraged states and utilities to pursue this path. Even though the Supreme Court of the United States has issued a “stay” on the CPP, some states are moving ahead with CPP planning and/or related efforts. We appreciate these efforts as the CPP represents a significant step forward in our nation’s efforts to mitigate against climate change. ... More
