“Renewable Natural Gas” Is the Ultimate Red Herring
There are three fossil fuels we must stop burning if we are to save our planet: coal, oil, and methane (aka “natural”) gas. Coal is declining precipitously. Scientists think we hit peak coal in 2013, and American use of coal has fallen by over 50% in the last 10 years (though, we need to quickly nail this coffin closed considering how dirty and polluting coal is). Oil is seeing the writing on the wall as major automakers commit to electric vehicles. Many think 2019 may have been the year we hit peak oil, and EVs are expected to make the internal combustion engine a “historical technology” by 2040. The faster we historicize petroleum, the better, so please buy that electric car or e-bike today.
Natural gas (aka methane) now comes into sight as the next fossil fuel we need to banish in the quest to rescue ourselves from the most catastrophic climate catastrophe. Burning methane is currently responsible for nearly 25% of all carbon emissions in the US, and its use is growing. Methane is also deeply embedded in many of our homes, and this will make it a challenge to extricate. We aren’t anywhere near hitting peak natural gas usage on our current trajectory.
But, as of recently, some American cities, mostly in California, have recognized the need to eliminate gas and slowly get us off the fossil sauce. In 2019, these leading cities did something that had never been done in the history of our species — they started banning future use of methane in new construction. The idea has been to stop digging a hole that we have to quickly climb out of, so they legislated that no new homes or buildings should be built with methane hookups. This will avoid costly retrofits later. The city-led ban began in California, has reached over 50 cities, and is spreading up the West Coast like a good kind of wildfire.
Enter “Renewable” Natural Gas
Any entrenched industry will fight with all its might not to disrupt revenue streams, regardless of the effects of their products on humanity (see: oxycontin and tobacco). So, it is to be expected that methane peddlers will spend the next crucial decades resisting efforts to ban their product. They’ll use lots of arguments to slow humanity’s inexorable push towards a fossil fuel future. The most ingenious/insidious one that we must quickly debunk is that their carbon polluting fuel is actually clean or has the potential to become so.
Enter, stage right, “renewable natural gas,” or RNG, a brilliant buzzword for a product that companies are counting on consumers to believe in, to continue with business mostly as usual. Renewable natural gas is methane that comes from biological sources like human and cow sewage or landfills. It differs from current methane, which is fracked from the earth’s interior, some of which escapes through pipes, while the rest is burned, adding to our dangerous warming blanket. RNG harnesses methane being created anyway and thus, doesn’t add new layers to our greenhouse problem. A group of nonprofits in my region just released an in-depth look at renewable natural gas and the numbers aren’t good.
How to Make Renewable Natural Gas — Anaerobic Digestion and Gasification
Before we can examine how much RNG our society will be able to realistically produce, let’s briefly talk about the two ways to make renewable natural gas. Even though, as we’ll shortly see, RNG won’t come remotely close to meeting our current gas demand, it still has the potential to be an important, lower-carbon tool in reducing the emissions of hard-to-decarbonize applications (like industry).
The first way to make RNG is through anaerobic digestion technology. This is a process where bacteria eat waste in an atmosphere that doesn’t contain oxygen (anaerobic). Sewage treatment plants and pig farms use this process. They gather fecal matter, bring bacteria to a specific temperature, do a lot of other magic in pipes, and out comes methane gas. Landfills are another source of this methane as wasted food and other fun stuff are eaten by bacteria underground and methane is created as a byproduct.
The second way to make RNG is through thermal gasification, which “uses energy to turn agriculture and commercial forest harvest residues” into something called Syngas. Syngas can then be converted to methane with more processing. According to a large survey by the State of Oregon, “There are currently no commercial-scale thermal gasification plants in the United States that convert biomass into methane. The existing plants produce syngas, which is burned and used to generate heat and electricity.” So thermal gasification is a potentially important, but unproven technology that should not make us believe that we can simply keep burning gas in our homes.
How Much Renewable Natural Gas Could We Conceivably Produce?
In the 2018 Oregon study cited above, (which had many gas industry officials involved in its writing) researchers looked at what we could optimistically hope for from RNG production. The numbers aren’t good. The potential for anaerobic digestion is 4.6% while the potential for thermal gasification is 17.5% of current natural gas usage in the state. So RNG could potentially cover 20% of the methane gas we use today, assuming significant investments in technology and distribution systems that do not exist today – in other words and not anytime soon.Think about it. We could work our tushies off over the next couple, crucial decades, to try to decarbonize natural gas pipes, while the planet is heating up and wildfire smoke is crossing our country coast to coast, and after crucial time and work, we’d still be using 80% fracked, fossil natural gas. If that’s not backing the wrong horse, then I don’t know what is.
Oregon’s numbers are similar to national numbers. Another study found that, nationally, we could hope for about 16% renewable natural gas, and again, this is far in the future and only if we invest heavily in RNG.
Compare that to electricity as a fuel, and you’ll see a stark difference. Right now, the national electric grid gets 20% of its power from renewables and 20% from nuclear, making electricity 40% carbon free. Biden wants to get to 100% by 2035. Oregon recently passed a law to get to 80% clean electricity by 2030 and 100% by 2040. Wind and solar are carbon neutral and are the cheapest and most installed forms of new energy generation. We have the roadmap and the tools to completely decarbonize electricity over the next 10–20 years and are doing so faster than anyone expected. Clean electricity is real, proven, happening and the horse we should be backing.
Electrifying our house and capping our natural gas pipe was one of the best things my family has done for the climate.
Other problems with renewable natural gas
There are other significant problems with renewable natural gas which are highlighted in depth in this brilliant article by Laura Feinstein and Eric de Place. Renewable natural gas isn’t even zero carbon. It is true that it often comes from existing sources of methane, but often those sources of methane could be avoided. Take landfills for example. When we toss food scraps into landfills it creates methane. We could capture that methane to make renewable natural gas or we could compost the food scraps like many cities and nations do, and avoid making that methane in the first place and get the benefits of richer, healthier soil in our communities. Relying on renewable natural gas could thus lock us into wasteful, inefficient practices when other options exist.
Another significant problem is that RNG costs a lot to make. A million BTUs of methane gas currently costs $3. The median cost for the equivalent amount of RNG is about 6 times that, at $18. Yipes! Imagine telling consumers that their gas bills are going to sextuple, and you’ll start to see how viable RNG is as a long term solution.
Scratch the surface, and it’s easy to see how RNG meets the classic definition of a red herring; “something that misleads and distracts us from a relevant or important question.” There won’t be very much of it, and it’s going to be very expensive. Let’s not get sidetracked from real climate solutions. When our local methane suppliers use the word “renewable” to keep pumping fossils into our homes, we need to understand that this is at best a stalling tactic and a greenwash to distract from the dangers of methane gas. Let’s stay focused on more realistic solutions for heating our homes and addressing the climate crisis like electrification.

Over the next two years, homebuilder Lennar is outfitting more than 1,500 new Colorado homes with Dandelion Energy’s geothermal systems in one of the largest residential geothermal rollouts in the US.
The big draw for homeowners is lower energy bills and cleaner heating and cooling. Dandelion claims Lennar homeowners with geothermal systems will collectively save around $30 million over the next 20 years compared to using air-source heat pumps. Geothermal heat pumps don’t need outdoor AC units or conventional heating systems, either.
Geothermal systems use the sustained temperature of the ground to heat or cool a home. A ground loop system absorbs heat energy (BTUs) from the earth so that it can be transferred to a heat pump and efficiently converted into warmth for a home. Dandelion says its ground loop systems are built to last for over 50 years and should require no maintenance.
Dandelion’s geothermal system uses a vertical ground closed-loop system that is installed using well-boring equipment and trenched back into the house to connect to a heat pump. The pipes circulate a mixture of water and propylene glycol, a food-grade antifreeze, that absorbs the ground’s temperature. A ground source heat pump circulates the liquid through the ground loops and it exchanges its heat energy in the heat pump with liquid refrigerant. The refrigerant is converted to vapor, compressed to increase its temperature, then passed through a heat exchanger to transfer heat to the air, which is circulated through a home’s HVAC ductwork.
Daniel Yates, Dandelion Energy’s CEO, called the partnership with Lennar a “new benchmark for affordable, energy-efficient, and high-quality home heating and cooling.” By streamlining its installation process, Dandelion is making geothermal systems simpler and cheaper for homebuilders and homeowners to adopt.
This collaboration is happening at a time when Colorado is pushing hard to meet its clean energy targets. Governor Jared Polis is excited about the move, calling it a win for Coloradans’ wallets, air quality, and the state’s leadership on geothermal energy. Will Toor, executive director of the Colorado Energy Office, said that “ensuring affordable access to geothermal heating and cooling is essential to achieve net-zero emissions by 2050, and we’re excited to be part of such a huge effort to bring this technology to so many new Colorado homes.”
And it’s not just about cutting emissions – geothermal heat pumps help reduce peak electric demand. Analysis from the Department of Energy found that widespread adoption of these systems could save the US from needing 24,500 miles of new transmission lines. That’s like crossing the continental US eight times.
Colorado is making this transition a lot more attractive through state tax credits and Xcel Energy’s rebate programs. These incentives slash upfront costs for builders like Lennar, making geothermal installations more financially viable. The utility’s Clean Heat Plan and electrification strategy are working to keep energy bills low while meeting climate goals.

Polestar has removed the Polestar 2 from its US website header in an early sign of how new tariffs will restrict choice and competition for American consumers, thus increasing prices.
The Polestar 2 is Polestar’s first full EV – the original Polestar 1 was a limited-edition plug-in hybrid.
It started production in 2020 in Luqiao, Zhejiang, China, where Polestar and Volvo’s parent corporation, Geely, was founded.
And there’s the rub: while Polestar’s newer EV, the 3 (which we just drove the new single motor version of last week), is built in South Carolina, the 2 is not.
Unfortunately, that interacts with some news that has been getting a lot of play lately: tariffs.
The US has been gradually getting stupider and stupider on the issue of tariffs, apparently determined to increase prices for Americans and decrease the competitiveness of American manufacturing in a time of change for the auto industry.
It is widely acknowledged (by anyone who has given it a few seconds of thought) that tariffs increase prices and that trade barriers tend to reduce competition, leading to less innovation.
It started with 25% tariffs on various products from China, implemented in the 2018-2020 timeframe. Then, in 2024, President Biden implemented a 100% tariff on Chinese EVs, effectively stopping their sale in the US. These tariffs included some exceptions and credits based on Volvo’s other US manufacturing, which Polestar had used to keep the most expensive versions of the 2 on sale in the US, while restricting the lower-priced versions from sale. Nevertheless, they were a bad idea.
Now, in yet another step to make America less competitive and inflate the prices of goods more for Americans, we got more tariff announcements today from a senile ex-reality TV host who wandered into the White House rose garden (which he does not belong in). These tariffs do not include the same exceptions as the previously-announced Biden tariffs.
Apparently this has all been enough for Polestar, as even in advance of today’s tariff announcements, the company suddenly removed its Polestar 2 from its website header today.
The change can be seen at polestar.com/us, where only the Polestar 3 and 4 are listed in the header area. On other sites, like the company’s Norwegian website or British website, the car is still there. The Polestar 2 page is still up on the US website, but it isn’t linked to elsewhere on the site (we’ll see how long it stays up).
We reached out to Polestar for comment, but didn’t hear anything back before publication. We’ll update if we do.
It makes sense that the Polestar 2 would still be for sale elsewhere, as it only started production in 2020. Most car models are available for at least 7 years, so this is an earlier exit than expected.
So it’s likely that all of the tariff news is what had an effect in killing the Polestar 2.
Then again, this is also just the second day of a new fiscal quarter. Perhaps the timing offers Polestar an opportunity to make a clean break – especially now that the lower-priced version of its Polestar 3 is available.
Despite the lower $67.5k base price of the new Polestar 3 variant, that represents a big increase in price for the brand, which had sold the base model Polestar 2 for around $50k originally, before all of these tariffs.
Update: Polestar got back to us with comment, but understandably, it doesn’t say much:
Polestar is a three-car company and Polestar 2 is available for customers now. There are a select number of Polestar 2s in stock at retailers that can be found on Polestar.com, but Polestar 3 and Polestar 4 will be the priority in the North American market.
Electrek’s Take
This isn’t the first car that America has been deprived of due to tariffs. The Volvo EX30, one of our most anticipated vehicles, and Electrek’s Vehicle of the Year for 2024, had its American availability pushed back due to tariffs.
Volvo decided to build the car in Belgium and export it to the US, but now that new tariffs apply to the EU as well, maybe that low-priced, awesome, fast, small EV will instead stay in Europe instead of being shipped overseas.
This shows how mercurial tariff fiats from an ignoramus are bad for manufacturing, as they mean that companies can’t make plans – and if they can’t make plans, eventually, they’ll probably just write the country making the random decisions out of their plans so they don’t have to deal with the nonsense.
And we’ve heard this from every businessperson or manufacturer representative we’ve talked to at any level of the automotive industry. Nobody thinks any of this is a good idea, because it objectively is not. All it does is make business harder, make the US less trustworthy, make things more expensive, and overall just harm America.
Yet another way that Americans are getting screwed by this stupid nonsense. 49% of you voted for inflation, and 100% of Americans are now getting it. Happy Inflation Day, everyone.

Lucid Motors (LCID) has now had six straight quarters with higher deliveries. The delivery record comes just as Lucid prepares to begin delivering its first electric SUV, the Gravity, to customers by the end of this month.
Lucid sets sixth straight delivery record in Q1 2025
Lucid delivered 3,109 vehicles in the first quarter, up 58% from last year and topping its previous record of 3,099 set in Q4 2024.
The company also produced 2,213 vehicles at its Casa Grande, Arizona, plant in the first three months of 2025, an increase of 28% from last year. Another 600 vehicles were in transit to Saudi Arabia, where they will be assembled at its new AMP-2 plant, Lucid’s first international manufacturing facility.
At this pace, Lucid will easily top the roughly 10,200 vehicles it delivered last year in 2025 at around 12,500. Lucid will likely see even more growth this year, with customer deliveries of its first electric SUV starting soon.
During the Gravity SUV’s “celestial arrival” last week in NYC, Lucid’s interim CEO Marc Winterhoff said the EV maker is “nearly finished building all the vehicles that we wanted to build to put them into our studio and for test drives.”
| Q4 2022 | Q1 2023 | Q2 2023 | Q3 2023 | Q4 2023 | Full-year 2023 | Q1 2024 | Q2 2024 | Q3 2024 | Q4 2024 | Full-year 2024 | Q1 2025 | |
| Lucid EV deliveries by quarter | 1,932 | 1,406 | 1,404 | 1,457 | 1,734 | 6,001 | 1,967 | 2,394 | 2,781 | 3,099 | 10,241 | 3,109 |
Winterhoff added, “by the end of April, we will resume customer deliveries of the Gravity.” Lucid delivered the first models in December, but they were for employees, friends, and family.
Lucid calls the Gravity a “no compromise” SUV with a range of up to 450 miles, 120 cubic feet of interior space, advanced technology, and sports car-like performance. The Gravity Grand Touring starts at $94,900, while the Touring model will arrive later this year at $79,900.
The new delivery record comes after Winterhoff told Fox Business last week that Lucid has seen a “dramatic uptick over the past two months” in orders from former Tesla drivers.
Currently, “50% of all the orders we have are from former Tesla owners,” Lucid’s CEO said. Winterhoff added that many are “looking for an option to not continue having a Tesla.”
Will we see the trend continue? Tesla announced earlier today that it delivered 336,681 vehicles in the first quarter, far less than the 390,000 Wall Street analysts expected.
