As carbon emissions from fossil fuels keep warming the planet, eco-conscious consumers may wonder if there’s a way to buy electricity from renewable sources without installing technology like solar panels or windmills on their property.

In short, the answer is yes.

However, the option isn’t necessarily available to all homeowners and renters. It also often comes with a slight price premium, experts said.

Few people are aware they can buy green energy

Renewable energy sources — including wind, solar, hydropower, geothermal and biomass — accounted for about 21% of U.S. electricity generation in 2023, according to the U.S. Energy Information Administration.

Most, 60%, came from fossil fuels like coal, natural gas and oil. These energy sources release carbon dioxide, a greenhouse gas that traps heat in the atmosphere and contributes to global warming.

The White House aims for electricity generation to be free of greenhouse gas emissions by 2035.

How wave power could help drive the clean energy revolution

A growing number of individuals and organizations are opting to shift away from fossil fuels: About 9.6 million customers bought 273 Terawatt hours of renewable energy through voluntary green power markets in 2022, according to the National Renewable Energy Laboratory. That’s up fivefold from 54 TWh in 2012.

In the voluntary market, customers buy renewable energy in amounts that exceed states’ minimum requirements from utility companies. Over half of U.S. states have policies to raise the share of electricity sourced from renewables, though most targets are years away.

Voluntary purchases accounted for 28% of the renewable energy market (excluding hydropower) as of 2016, according to the Environmental Protection Agency. They help increase overall demand for renewable electricity, thereby driving change in the energy mix, the EPA said.

The bulk of the increase is from corporations, according to NREL estimates. Residential sales have grown, too, but more slowly.

Just one in six U.S. adults know that they may have the option to buy renewable power, either from their electric company or another provider, according to most recent NREL survey data on the topic, published in 2011.

“The market does continue to grow every year in terms of sales and customers,” said Jenny Sumner, group manager of modeling and analysis at NREL, a national laboratory of the U.S. Department of Energy.

“But very few people are aware” they can opt in to green programs, she said. “It’s just not something that’s top of mind for most people.”

How consumers can buy green power

Power companies may offer “green pricing programs,” for instance.

Customers in these programs — also known as utility green power programs — pay their utility a “small premium” to get electricity from renewable sources, according to the U.S. Energy Department.

The cost generally exceeds that of a utility’s standard electricity service by about 1 to 2 cents per kilowatt hour, Sumner said.

That may roughly translate to about $5 to $15 more per month, Sumner said. It will ultimately depend on factors like program price and household energy use, she added.

Nearly half of Americans, 47%, said they were willing to pay more to get their electricity from 100% renewable sources, according to a 2019 poll by Yale University’s Program on Climate Change Communication. On average, they said they would be willing to pay $33.72 more per month.

Green power marketing programs

Consumers in some states can also opt into “green power marketing programs.”

Such states have “competitive” energy markets, meaning consumers can choose from among many different companies to generate their power. (Unlike with “green pricing programs,” the company generating the renewable power may not be the customer’s utility, which distributes the power.)

Residential green power options are available in these states with competitive (also known as “deregulated”) markets: California, Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Texas and Virginia, according to the U.S. Energy Department and EPA.

These also tend to come with a premium, though in some regions they “may be price competitive with default electricity options,” the agencies wrote.

Community choice aggregation

With “community choice aggregation” programs, local governments buy power from an alternative green power supplier on behalf of their residents.

The municipality essentially operates as the supplier for the community’s electricity, Sumner said. These programs are especially prevalent in California, she said.

Unlike the other program types, residents generally don’t have to opt in to community choice programs; it’s typically automatic and consumers can opt out if they wish, Sumner said.

How renewable energy certificates (RECs) work

Just because a consumer opts for renewable power doesn’t mean the electricity being pumped into their home is coming from those renewable sources.

This may sound strange. But it’s due to the physical nature of electricity and its movement through the shared electric grid.

“Once the electrons have been injected into the grid, there’s no way of tagging that these are ‘green’ electrons and these are not green,” said Joydeep Mitra, head of the power system program at Michigan State University. “Nobody knows which electrons are going where.”

Green energy programs instead rely on “renewable energy certificates,” or RECs.

The certificates are essentially an accounting mechanism for the generation and purchase of renewable energy, Mitra said.

You may not be getting the green power — but someone, somewhere is. And RECs keep track of it all.

Any consumer — even one who doesn’t have access to a green power program through their utility — can also purchase a REC as a separate, stand-alone product. It’s a way to provide extra funding to a renewable energy project, typically sold by a broker or marketer rather than a utility, Sumner said.

Buying these certificates separately doesn’t impact a consumer’s existing utility service relationship.

How to verify your electricity is green

Experts recommend choosing a green power option or REC that has been verified by an independent third party.

That’s because the voluntary sales and purchases of renewable energy aren’t subject to government oversight, according to the EPA and U.S. Energy Department.

One such independent body is the Center for Resource Solutions, a nonprofit that oversees the Green-e certification standard, the agencies said.

For example, Green-e polices the disclosures energy suppliers make to consumers about renewable energy, and verifies the purchase of that energy isn’t being counted toward state energy mandates, among other things.

2024 Cadillac LYRIQ buyers could score ,500 in discounts

The all-electric Cadillac LYRIQ was an Electrek favorite when it first made its debut two years ago. Now, LYRIQ buyers who have been waiting for a deal can score more than $10,500 in discounts on the Ultium-based Caddy.

Our own Seth Weintraub said that GM had come in, “a year early and dollar long at $60K” when he first drove the Ultium-based Cadillac LYRIQ back in 2022. He called the SUV “a stunner,” too, heaping praise on the LYRIQ’s styling inside and out before adding that the EV’s ride quality really impressed on long journeys.

Well, if the first mainstream electric Cadillac was a winner at its original, $57,195 starting price (rounded up to $60K for easy math), what could we call it at $10,500 less?

That’s a question that’s suddenly worth asking, thanks to huge GM discounts on the LYRIQ that prompted the automotive pricing analysts at CarsDirect to name the 2024 LYRIQ one of the industry’s “Best New Car Deals” this month:

A slew of incentives can enable you to save big on a 2024 Cadillac LYRIQ. First, EVs eligible for the federal tax credit qualify for $7,500 in Ultium Promise Bonus Cash from GM. Additionally, competing EV owners can score $3,000 in conquest cash.

Meghan Carbary | CarsDirect

With more than 100 kWh of battery capacity and 300-plus miles of real-world driving range (plus available 190 kW charging capability) the Cadillac LYRIQ ticks all the boxes – but you don’t have to take just my word for that.

Volvo CE rolls out autonomous equipment at Volvo Days 2024 [part 2]

Volvo CE rolls out autonomous equipment at Volvo Days 2024 [part 2]

Volvo Days 2024 packed a lot of innovative new products into a few short days, but the company’s autonomous construction robots still managed to stand out.

A global shortage of qualified operators is impacting job sites everywhere, precisely at a time when demand for housing, mineral mining, and renewable energy construction is going from peak to peak. That’s why companies from Caterpillar to Tesla to Einride are pushing to advance autonomy the way they are.

And, like they’ve done with semi truck electrification, Volvo Group’s vision for the future has them firmly in a leadership role as the construction industry automates.

CX01 autonomous hybrid compactor

Volvo CE Unveils CX01 Single-Drum Asphalt Compactor Concept

First revealed as a concept in 2021, Volvo CE’s CX01 autonomous “single drum” asphalt roller concept has seen continuous development in the years since. Making its Volvo Days debut, the CX01 has shed the original single drum design for a “split drum,” with each half being controlled by an internalized, independent electric motor.

The CX01’s electric motors not only help to propel and steer the roller, they also vibrate the drums individually, using some trick software calibration to effectively “cancel each other out,” delivering all the benefits of vibrating drum rollers without the noise.

It’s so smart, you guys

It’s also worth noting that the CX01 is something of an “extended range” EV, instead of a “pure” BEV. That’s because it uses a small, 1.4L diesel engine to spin a generator that powers not batteries, but capacitors (those blue things, above right). Those capacitors can be charged on grid power (or from an accompanying TC13 trench compactor), but they’re much better than batteries at releasing energy really quickly, enabling the diesel to operate at its maximum efficiency while maintaining extremely precise, high-torque movement from the motors.

Volvo CE engineers envision a team CX01 rollers units deployed on larger job sites that could work together and communicate with other pieces of equipment on the site. The connected equipment could help survey the job site, report on the conditions of the mat (density, temperature, and passes), and leverage AI to determine when and where to compact without the need for human operators.

All of which is great, sure – but they had me at “giant OneWheel.”

Volvo TA15 autonomous electric haul truck

Part of Volvo CE’ “TARA” line of autonomous products, the “production ready” TA15 autonomous electric haul trucks are already part of a number of pilot programs on Volvo customer job sites. Being autonomous, they’re ideally suited to performing repetitive routes, dozens of times per day, without exposing human operators to fatigue or injury.

Big robot dumper

The Volvo TA15 is a fully automated electric dumper designed to operate on busy job sites with tight tolerances. With the TA15, Volvo says customers will be able to replace larger, diesel-powered vehicles with a fleet of smaller, “right sized” Volvo TA15s. The electric haul bots offer cleaner, quieter operation and increase efficiency.

“TARA enables you to downsize and replace larger diesel-powered vehicles with a fleet of autonomous electric Volvo TA15s capable of running 24/7,” reads the official TARA release. “This not only helps you cut emissions and increase productivity, it will also help you rightsize your machinery and optimize your hauling routes.”

And that brings us to the real topic at hand: sustainability.

Electrek’s Take

Volvo SD110 single drum roller, via Volvo CE.

As we’ve often discussed on The Heavy Equipment Podcast, there are two types of sustainability, and both are important. The first is the “classic” version of sustainability, in that our choices need to sustain the planet and environment we live in. The second is sustainability of the business – the ability to keep doing business in a way that ensures the survival of the business, itself.

Looking at the conventional Volvo SD110 conventional roller, above, you can see the incredible amount of materials – of steel, rubber, plastic, glass, etc. – that simply isn’t needed to produce the CX01 roller we started this article with.

All that added mass has a massive hidden carbon cost. The cost of getting those materials out of the ground, the need for bigger, heavier roads to support the weight of the machine, and the bigger, burlier trucks and trailers needed to transport it. Heck, even the operator’s commute to and from the job site adds to the carbon cost of the SD110, over and above the harmful emissions from its diesel engine’s exhaust stack.

The CX01? It’s objectively more sustainable than the SD110 roller in every way, and does pretty much the same job.

The Volvo TA15, too, is lighter and more compact than a conventional rigid haul truck. That reduced mass enables job sites and mining operations to maintain narrower haul routs that are less expensive to build and easier/cheaper to maintain, all while contributing to carbon reductions all across even the broadest scope of job site operations.

That’s both sustainable, and sustainable – and just another reason why forward-thinking fleet buyers will be watching this space closely.

JB Hunt launches first electric aftermarket semi truck route in Arizona

Following successful inbound implementations in the Pacific Northwest, North Carolina, and Mexico, Daimler Trucks North America (DTNA) is expanding the reach of its electric semi fleet into Arizona with long-time associate JB Hunt.

JB Hunt will add the new Freightliner eCascadia electric semi to its Arizona fleet immediately, and put it to work delivering aftermarket truck parts from DTNA’s parts distribution center (PDC) in Phoenix to multiple DTNA dealers along a dedicated route.

The electric Freightliner truck is expected to cover approximately 100 miles in a given day before heading “home” to a Detroit eFill charger installed at Daimler’s Phoenix facility.

This milestone marks the first all-electric route in the DTNA aftermarket parts distribution network, significantly reducing carbon emissions and setting a precedent for future sustainable outbound logistics operations.

“This solution with DTNA is a great example of our commitment to supporting customers’ efforts to reduce their carbon footprint and work towards energy transition,” explains Greer Woodruff, executive vice president of safety, sustainability and maintenance at JB Hunt. “JB Hunt owns and operates several eCascadias on behalf of customers, and our drivers have really enjoyed their in-cab experience. As customer interest continues to grow, we are here to enable their pursuit for a more sustainable supply chain in the most economic means possible.”

Daimler is analyzing future expansion opportunities throughout its internal parts distribution and logistics with an eye on electrifing additional routes and further reducing the carbon footprint of its logistics operations.

JB Hunt will evaluate its utilization of the charging station for other customers in the area, eventually enabling fully integrated zero-emission vehicle solutions into its 3PL fleets.
