The electric bus market is booming. As of September, more than 200 transit agencies nationwide had purchased more than 2,000 electric buses. Colorado’s Regional Transit District (RTD) has one of the largest electric bus fleets in the country with 36 all-electric MallRide buses traveling up and down the 16th Street Mall in downtown Denver. Electric buses have zero tail-pipe emissions and produce about half as much global-warming pollution as diesel buses making them better for public... More

Conversations centered on transportation electrification continue to pick up steam across the Southwest. This is especially true in Arizona since the Arizona Corporation Commission approved two electric vehicle policies in January 2019 and July 2019. Heightened interest in transportation electrification policies is one reason why SWEEP, Plug In America, and Arizona State University’s Energy Policy Innovation Council, recently organized the first annual Arizona Transportation Electrification...

As SWEEP reported earlier, energy efficiency jobs are booming in the Southwest, growing almost 5% between 2017 and 2018 according to the 2019 U.S Energy and Employment report. Increasing energy efficiency reduces greenhouse gas emissions, saves customers money on their energy bills, and provides a significant source of employment. A new report provides more detail on the key role of energy efficiency jobs in the Southwest and highlights the differences among states based on recent policy and ... More

The town of Basalt, Colorado had a big problem. The local school district was struggling to attract and retain quality teaching staff due to low wages (30% less than comparable schools) and high local housing costs (30% more). But an innovative solution arose from this difficult situation that has resulted in an incredible community collaboration to build Basalt Vista, an all-electric, net zero, affordable housing community. Roaring Fork Valley (RFV), Habitat for Humanity (H4H), and... More

Denver’s cannabis growing facilities (which are mostly indoor grows) account for about 4% of Denver’s total electricity consumption, while producing over 50% of the state’s supply of marijuana. Indoor grows are fairly energy intensive, consuming about ten times as much energy per square foot as a typical Denver office building. There are also many cost-effective opportunities to improve energy productivity (grams of product per unit of energy consumption) including more efficient lighting,... More

Electric vehicles (EVs) are becoming more popular by the day as the technology rapidly matures. The potential benefits over conventional gas-powered vehicles are numerous - they reduce emissions of carbon dioxide and other pollutants, reduce fuel costs, are easy to maintain, fun to drive, and are quickly becoming cost-competitive with traditional vehicles. For these reasons, many companies and local governments are quickly adding electric vehicles to their fleets. But what about... More

Most states adopt consistent and standard statewide building codes. But a handful of states – including the southwest states of Arizona, Colorado, Nevada, and Wyoming – leave code adoption up to each and every local jurisdiction, creating a patchwork of confusing and often-outdated codes. In Colorado, for instance, even though most high-construction areas have up-to-date codes, more than 150 jurisdictions have an energy code from 2009 or earlier, and another 50 jurisdictions have no building...

In 2018, new Governors were elected in Colorado, New Mexico, and Nevada. Likewise, state legislatures either remained in Democratic control or flipped to Democratic control in all three states. With new leadership, policymakers in these states made energy efficiency, renewable energy, and climate action priorities in 2019 legislative sessions. The advances for energy efficiency policy are noteworthy. In Colorado, the state legislature adopted minimum energy- and water-saving standards for 15 ... More

The Southwest region (Arizona, Colorado, New Mexico, Nevada, Utah and Wyoming) added 6,127 jobs focused entirely or partially on improving energy efficiency in 2018 according to the newly released 2019 U.S. Energy and Employment Report. Energy efficiency remains the top sector for energy jobs in the Southwest, ahead of oil and natural gas production, electric power generation, and other energy supply sectors covered in the report. The chart below shows the number of energy efficiency jobs in ... More

In the last few years, electric vehicles (EV) have emerged as the most promising clean transportation alternative to conventional gasoline and diesel-fueled vehicles. Pro-EV policies designed to accelerate the global transition to electric transportation have played a critical role. Automakers and other vehicle manufacturers have responded by shifting their investments toward the development of new electric vehicles – from sedans and SUVs, to pickup trucks, delivery vans, school buses, and...

As state and local officials tackle building energy code issues in 2019, they likely will hear discussions about how solar photo voltaic (PV) power should fit into the energy code, and if solar energy can “trade off” for energy efficiency. Some interest groups want policymakers to weaken the efficiency requirements for new homes if the houses also have solar energy, but those requests fail to understand three things: Solar energy and efficiency are not the same thing, and cannot be traded...

In November, 2018, Colorado joined 12 other states and the District of Columbia in adopting the California Low-Emission Vehicle (LEV) standards. The standards require the average real-world fuel economy of new vehicles to reach 36 mpg by 2025. Currently, the California LEV standards are identical to federal standards, but the Trump Administration is attempting to rollback the federal fuel efficiency standards and freeze the requirements in 2020, which will increase both pollution and fuel costs ...

One of energy efficiency’s many benefits is that it reduces greenhouse gas (GHG) pollution by decreasing the amount of electricity that utility companies must generate to meet customer demand. So, let’s look at just how big a role efficiency can play in cutting climate change pollution. In its recently released data on energy-related GHG emissions, the U.S. Energy Information Administration (EIA) showed a continued decline in nationwide GHG emissions from electricity generation. Nationally, EIA ... More

Imagine that you just bought a new condo and, since you care about saving the planet while saving yourself money, you’re also thinking about buying a new electric vehicle (EV). You check your new parking lot for an electrical outlet, only to find that there isn’t one. With persistence, you ask the property owner about installing an EV charging station in the parking lot for communal use, but after reviewing the building plans together, you discover that the property does not have the electrical ...

Just about every day I open the paper and read about some new technological or business development regarding driverless cars. Most of these stories come with breathless anticipation of all of the great things that autonomous vehicles will bring: fewer crashes, less congestion, more access for people who can’t drive. In some authors’ telling, personal car ownership will quickly become a thing of the past, replaced by electric “robo” taxis called up on a moment’s notice, paving the way for a... More

This fall, Colorado voters will make important decisions about transportation funding, but they need the facts to reach the right choice. The hard reality is that just building more highway lanes won’t solve either the urban traffic mess or the economic struggles in rural areas. Instead, Colorado needs a healthy mix of ways to get around – some road work, certainly, but also more buses, bike lanes, carpooling, and similar efforts, as well as a combination of state and local projects. Recent... More

Coloradans can help untangle their transportation woes by supporting a ballot measure, currently called Initiative 153, but they shouldn’t be fooled by a go-nowhere alternative that does nothing to solve the complex problem. SWEEP endorses one measure that appears to have made the ballot. On August 6, organizers from Let’s Go Colorado delivered 198,000 signatures to the Colorado Secretary of State for Initiative 153, which will let voters decide whether to raise the sales tax rate by 0.62...

The International Energy Conservation Code, or IECC, is one of a suite of model national building codes adopted by state and local jurisdictions to ensure a bare minimum of durability, quality, health, and safety. Once in a while, we hear building officials mistakenly say they don’t adopt or inspect for the energy code, “because it is not a... More

Yes, unfortunately an energy-inefficient building can make you sick, lead to premature death, and inflict social injustice. But the building industry and public housing officials can reduce this human suffering by taking steps to improve – wait for it – energy efficiency. That’s because efficiency improves air quality inside and out of homes and apartments, while also helping residents survive extreme weather events, heat waves, and cold weather. Moreover, energy efficiency reduces the need for ... More
