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.
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.

The BYD “Shenzhen” set sail on its first voyage overseas this week. With 9,200 parking spots, or about enough to fill 20 football fields, BYD’s new car transport ship is now the world’s largest.
BYD’s largest car carrier sets sail for Brazil
BYD’s Shenzhen is on its maiden voyage to Brazil after setting sail on April 27. The vessel is carrying over 7,000 new energy vehicles (NEVs), including electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs). It’s the largest single batch of NEVs exported from China so far.
The new vessel is BYD’s fourth car transport ship and the world’s largest, capable of carrying 9,000 vehicles. According to the company, that’s enough to fill about 20 football fields.
BYD launched its first car carrier, the Explorer No 1, in January 2024. It has already completed several trips to Germany, Spain, and Brazil.
Its second, the BYD Changzhou, set sail in December 2024, followed by the Hefei earlier this year. All three vessels can carry up to 7,000 vehicles, making the Shenzhen the largest so far.
The Shenzhen is named after the automaker’s hometown and demonstrates “BYD’s firm determination to promote sustainable development in Brazil.”
BYD is preparing to launch two more vessels, the Changsha and Xi’an. The Changsha is expected to launch soon, while the Xi’an was introduced on April 2.
The new car carriers will help accelerate BYD’s aggressive overseas expansion. In the first three months of 2025, the company sold over 206,000 NEVs overseas, more than double the number it sold last year.
BYD sells a wide range of vehicles in Brazil, including the low-cost Dolphin Mini, starting at around $20,000 (99,800 BRL). In October, it launched its first hybrid pickup truck, the Shark, starting at 379,800 BTL ($66,900).
Brazil is only one overseas market that BYD is targeting. BYD’s sales are expected to double in Europe in 2025, with significant growth in other key regions like Southeast Asia, Japan, Mexico, and South Korea, to name a few.

‘Tesla homes’ in a Houston neighborhood where all the homes have Tesla solar roofs and Powerwalls went for sale.
7 out of the 11 homes have reportedly already sold.
Tesla neighborhood is a term that is being used for new developments where all the homes integrate all or part of Tesla’s power ecosystem, including the Powerwall home battery pack.
The best example is a giant new development project in Austin, Texas, by Brookfield Asset Management and Dacra in which up to 12,000 new homes are to be built and offering Tesla solar roofs and Powerwalls.
However, since the announcement, it looks like only some of the homes in the new neighborhood have Tesla energy systems.
In 2022, Tesla also announced a similar project in Las Vegas.
A year later, the company claimed to have deployed “over 600 solar neighborhoods” worldwide, with a total capacity exceeding 100 MW.
One such ‘Tesla neighborhood’ is a small block of 11 townhouse homes featuring Tesla solar roofs and Powerwalls in Houston, Texas.
The homes were recently completed and went on sale, starting at $544,900.
Here are some pictures from the listings:
Utopia Homes, the developer behind the project, described the properties (via Chron):
Step into modern elegance expertly crafted by Utopia Homes. This property showcases groundbreaking Tesla Solar Roof Shingles and Power Wall technology, ensuring 100% energy security and eliminating electric bills for a truly sustainable lifestyle.
The house has proved popular according to the real estate agents, with 7 out of 11 homes already sold.
As we recently reported, Tesla’s solar roofs have proven to be a more expensive and niche product than the company previously presented.
Tesla has largely stopped discussing it, but it is still being deployed through some third-party installers, such as in this case, on new homes.
However, its Powerwall product remains a very popular solution for homeowners seeking greater energy independence and protection against outages, which have been a frequent problem in Texas.
More homeowners are turning to generators, and alternatives like home battery packs are gaining popularity.

Canadian electric propulsion specialist Vision Marine continues to graduate beyond advanced outboard motors into a provider of all-electric boats. This month, Vision introduced two new electric pontoon boats – the 12-passenger V24 and 15-passenger V30, each capable of a range up to 90 nautical miles.
Vision Marine Technologies ($VMAR) is a Canadian technology company with over 25 years of experience in the marine industry. The company made waves (literally) by introducing its E-Motion turnkey powertrain system, which it has since integrated into a catamaran speedboat, which set a speed record of 109 mph in 2022.
Since then, Vision has introduced six hp two-cruiser vessels – the Fantail 217 and Volt 180, each capable of transporting 10 passengers via its E-Motion technology. Most recently, Vision Marine has integrated the full power of its 180 hp electric powertrain technology into two additional vessels, both electric pontoon boats.
Earlier this month, the company officially began sales of the Vision V24 and V30, which you can view below.
Vision Marine brings power and range to electric pontoons
According to Vision Marine Technologies, orders for its two new electric pontoon boats are now open, and they are touting the same E-Motion technology that put the company on the map a few years ago.
The first model is the V24, a 12-passenger electric pontoon that is 24′ 8″ in length and has 180 hp. The ultra-quiet E-Motion powertrain is powered by a standard 43 kWh marine battery pack, offering 40 nautical miles (46 miles) of all-electric range on a single charge. For added range, Vision sells a version of the electric pontoon with a second battery pack, totaling 86 kWh and delivering up to 90 nautical miles (104 miles) of range.
While the V24 offers more of a classic attempt at the pontoon boat, Vision’s additional new vessel, the all-electric V30, is a tad sportier and provides room for more passengers aboard (15). This 30′ vessel features the same E-Motion powertrain options, complete with the same two battery configurations to offer the same ranges as the V24.
However, the V30 has additional features such as 4 x 6.5″ interior speakers and cool-touch seats. Both models feature an integrated onboard charger that supports both 120- 240V (30 to 50 amps) for seamless charging, no matter the dock plug while moored.
The Vision V24 starts at $99,995 for the standard battery pack version, while the V30 starts at a higher price of $139,995. As previously mentioned, both electric pontoon boats are available to order today.
