40% of US electricity is now emissions-free
40% of US electricity is now emissions-free
Good news as natural gas, coal, and solar see the biggest changes.
It is cheaper to operate and that has been it's selling point for the last years.
In case you're ever wondering, this is an example of your tax dollars at work. Thirty years ago solar and wind generation had to be heavily subsidized with government grants to make them viable in the energy market. Now the technology of both has advanced to the point that it's undercutting all of the other forms of electricity generation, without subsidization.
Government subsidies work. They're effective for getting new technologies off the ground.
Everything I find shows them as still being subsidized and receiving the lions share of energy subsidies, which is fine in my book.
A good chunk of that is nuclear which is not cheaper to operate.
It's worth pointing out that the renewables break down as such (% of all electricity):
- Solar: 6%
- Hydro: 6%
- Wind: 10%
- Nuclear: 18%
Nuclear energy is providing more than any other individual source, making up 45% of all renewable electricity.
Next time you hear someone "concerned about global warming" also fearmonger about nuclear energy, it's worth considering where their allegiances lie. Most people are misguided, but when it comes to politicians, it says a lot about how much they actually care about sustainability.
There have been studies (this one, for example) that suggest the total radioactivity-related health impacts from coal power exceed that of nuclear power by an order of magnitude. That's not all pollution-related deaths for coal -- just those associated with radon exposure inside of mines, and radioactive materials embedded in coal going out into the environment. For all the fear-mongering about nuclear, it's hard to find a less dangerous source of base load generation using present-day technologies. Maybe once grid-scale batteries are available at scale, they could replace nuke plants, but that's a solution ten years too late for an environmental problem we have to fix right now.
i wonder where the world we be today if we didnt stop funding nuclear, if gen 4 designs actually had proper money pushing them forward.
We'd be better suited to reduce emissions, that's for sure.
What is renewable about nuclear? It's not a fossil fuel, but uranium has to be mined and is a finite resource just like oil.
Uranium isn't the only fuel source, for one. Fusion reactors, if we can figure out the underlying science, world likely use hydrogen. New generation reactors can use Thorium, and breeder tractors are able to generate usable fuel from nuclear waste.
Not to mention, uranium is finite but we have enough supply of it to develop other technologies while we still reduce emissions via nuclear.
And this is discounting new technologies which could allow us to create a large artificial uranium supply.
Don't forget geothermal. California has a little of that
Geothermal is not quite to the point where we can represent it with a whole number percentage value, but it's getting there! If we're going to include sub-1% generators, burning wood has geothermal beat out at 0.8%. Geothermal is cool, though!
Nuclear has been at that supply level since the 1970s. Other parts of the world have much higher renewable mixes in their energy inputs. For example, Germany:
Nuclear is not necessary to meet climate change targets. In fact, it's so damned expensive to deploy and maintain, it will harm meeting those targets.

And because they shut down their nuclear plants, they had to start burning coal again, which is about as bad an energy source you can get when it comes to emissions and pollution. Their coal use % went up from 2021 to 2022. They may have a higher renewable mix, but they've also increased their emissions. Not to mention, they also significantly reduced their energy imports from France -- the majority of which is generated by nuclear energy. They are replacing clean energy with coal.
France is actually a significant counterpoint as well. They've got 65%+ nuclear energy, and renewables just add to the percent of clean energy sources. Considering they're doing much better than Germany in terms of not using fossil fuels, I believe they are an example to follow over Germany -- which means nuclear is critical to meet our climate goals.
The only thing that's keeping carbon-free power from growing faster is natural gas, which is the fastest-growing source of generation at the moment, going from 40 percent of the year-to-date total in 2022 to 43.3 percent this year. (It's actually slightly below that level in the October data.) The explosive growth of natural gas in the US has been a big environmental win, since it creates the least particulate pollution of all the fossil fuels, as well as the lowest carbon emissions per unit of electricity. But its use is going to need to start dropping soon if the US is to meet its climate goals, so it will be critical to see whether its growth flat lines over the next few years.
Uh... So, listen. I work in the Nat Gas sector. And while I'm happy to confirm that its far cleaner, easier/safer to transport, and more efficient than coal and liquid oil, I'm going to have to pump the breaks on the enthusiasm. We are definitely not "emissions-free". One of the larger investments we've made, in the last few years, has been in detecting gas leaks along our existing lines and plugging them. And we definitely still flare off excess and lose reserves during transit as circumstances dictate.
Way back in the 1970s a small upstart energy company known as Exxon had one of its engineering departments estimate the ecological impact of drilling into the East Natuna gas field off the coast of Indonesia. This was primarily a natural gas reserve, accessible without the modern fracking and cracking techniques used throughout the Permian and Delphi Basins.
Senior scientist of Exxon, James Black, authored a report estimating the impact of drilling and burning off the fuel in the East Natuna reserve, and concluded it would result in a significant increase in global temperatures. This lead Exxon to commission further studies, in the late 70s and early 80s, to estimate the full impact of their drilling and refining practices. The end result was a model of climate change that has mapped neatly to current climate trends
I say this because while natural gas is relatively cleaner, it is by no means clean. And with the increasing rate of energy consumption occurring globally, our reliance on natural gas is decidedly not contributing to an emissions free future.
I don't think anyone is under the illusion that natural gas is emissions-free.
6% Solar + 6% Hydro + 10% Wind + 18% Nuclear = 40% "emissions-free"
They certainly exist. There was a Dutch guy in another post bragging about his micro-nation being 100% emissions free because he kept seeing his government bragging about being "100% green energy," while the supermajority of their electricity was generated with natural gas (being the only significant fossil fuels they had and it being relatively easy to source from neighbors)
The point isn't there was one guy who fell for it, the point is there will be people mistaking natural gas for actual green energy instead of just being less harmful, or being unaware of what's actually producing their electricity simply because there is a deliberate effort to mislead people about it by, among other things, conflating terminology like "green" and "emission free."
The article doesn't do a good job of explaining the 40%, you have to infer it. But when you do, it isn't natural gas, but solar + wind + hydro + nuclear.
This is actually fantastic news. 40% renewable, 40% natural gas, and 20% coal is a huge step in the right direction.
Thanks for continuing to prove why weevils are the best beetles.
This is economics now, not politics. US can go full crazy Trump, but the grid will just keep getting greener as greener is cheapest. He can rant and rave about global warming being a conspiracy or anything else, but it's unstoppable now.
No, the grid won't get greener if Trump is elected because he WILL go full dictator. And he will revert everything that is being done currently.
Still plenty that can be done to stop it. Preventing transmission lines, giving even bigger subsidies to fossil fuels, putting large tarrifs on imported solar panels and wind turbines. Just look at California the power monopoly is in with Gavin Newsom and they created rules that protect their profits above all else and now solar installs is at 20% what it was before.
That's a very cool article, I didn't know the US was actually making the change so quickly.
Weirdest part of the article is the included pie chart from the US Energy Information Agency showing the usage of different types of energy, but the entire pie is orange, like every slice of different energy is orange.
They need one art guy, just one.
I didn't mind the pie chart, the slices are labeled clearly, no need to use coloring like you have to read a legend.
Kind of you
It's better than nothing. Hopefully we can speed this up in next couple of years.
That’s actually better than I thought.
In my city they had everyone switch to renewable energy, they sent Mail out stating that your energy source will automatically change unless you opt out.
LOL how are they going to change the energy source that powers an individual house if they "opt out" ??
Did they run separate power lines to every house that is on a switch between the power sources? It's not like a network packet that you can route to a destination, it's going to go down the lines the same way unless the circuit is broken.
My state separates power “distribution” as the responsibility of the utility, from “generation” as an attempt at a competitive market. I choose my source f power by choosing what generation company I pay. Clearly, electrons are electrons, but for the power I use I pay a 50% renewables company to generate
If 90% of households have clean energy selected, and 10% prefer to pollute, the city will buy the relevant amount of clean energy.
My city gave no option. It only buys clean energy
it's "ghost" economics, if for example i live in a house that choose to pay for coal power over hydro power, my money goes to the coal power plant (or at least not to the hydro plant) if i choose to pay for hydro, that money goes to the hydro plant instead (most likely not the coal plant)
if you actually dig into power co-ops and whatever other shenanigans you find, in the US at least, you will find there are multiple layers between "the utility" and who generates the power. For example, here where i live, we have a local power utility, who buys power from a power co-op, who buys power from power plants, and possibly other power co-ops? It's really disorganized, basically the TL;DR is that it wouldnt matter even if there were separate distribution lines. It's completely irrelevant based on the complexity of the actual market anyway lol.
Suppose Provider A is 100% renewable and Provider B is 100% fossil. Both providers generate power and feed the same grid (which is managed separately from the various energy providers). The same grid powers all homes. Householders get to choose whether to buy from Provider A or Provider B. If you support renewables then you buy from Provider A; their share goes up and B's share goes down. And vice versa for B. In addition the government juggles A,B as well as C,D,E,etc to provide the overall service to the country.
Same AFAIK -- Akron, OH.
This makes electric cars less polluting with every passing day as this percentage increases.
Car manufacturing is, itself, a messy process. And we'd all be better off (for a whole host of reasons) if we could move to a public transit system and away from the messy, overly-complex, extraordinarily expensive highways-and-byways personal vehicle system.
Electrified rail and Multi-family homes would dramatically reduce both energy consumption AND housing costs, if we were willing to invest in it at rates comparable to what we spend subsidizing new fossil fuel wells, road expansion/maintenance, and policing of the homeless.
Ride sharing and self driving are a natural combo . A ride sharing system for self driving electric cars & light trucks would be a game changer for 'last mile' and intra suburban transport ,
And ride sharing would reduce the manufacturing cost of providing a fleet of these vehicles for a city since fewer vehicles would be needed for the same number of people.
Here are several use cases where it would be ideal.
1: Transport to your residence or place of work from a mass transit station in inclement weather , or for people with heavy things to carry or the disabled who find travel to the mass transit station impractical or impossible.
The vehicle would be stationed in a parking lot/recharging station at the mass transit station and be available for rent via an app , it would then return to the parking lot autonomously and connect to the recharger to be ready for the next person. or conversely it could be summoned via the app and drive autonomously to the customer to be used .
2: An electric light truck variant could be used for moving or furniture delivery.
3: Disabled individuals could have access to accessible electric vehicles on an 'on demand' basis making trips to the stores or friends far easier for them. And stores would not need dozens of disabled parking spots or even a parking lot at all , they would only need one or two accessible general use loading and unloading areas near the entrance. and the acres and acres of land that was once a parking lot could be repurposed as a park or community space of some kind , or perhaps rezoned to provide extra housing for an over populated area.
Great except the military pollutes more than 140 countries and there are several wars ongoing. If you really want the climate to stop changing we need to reel in the international shipping industry, the fashion industry, and also the global war machine.
You also have to admit that the US covers for most of the worlds military. Most of nato and many Asian allies have very low defense spending, because the US will cover them. Most of the time when there is a global crisis or localized crisis the US is involved in one way or another.
we need to reel in the international shipping industry, the fashion industry, and also the global war machine
Believe you mean "modernize" and not "reel in," because ending international shipping would be catastrophic worldwide.
If we're being pedantic, the post said "reel in" international shipping, not "ending".
Finally some good news.
There's a lot if you look for it, recent developments in tidal are incredibly positive and we're absolutely going to see a rapid uptake in marine electrification as existing technology progresses through the market. Most people never really think about the resources used and pollution caused by small boats but one of the big destructive forces at play is the infrastructure requirements - small boats need big boats to supply their fuel stations.
Transitioning away from this system and instead using costal tidal generators to charge electric ferries and barges could be a total game changer in many areas, especially many of the highly trafficked and polluted tidal basins like in north Brazil, Nigeria, or island clusters like in the Philippines. Also the intercoastal waterways around the US and other leisure spots.
We're making great progress in many areas and I really think it's important to acknowledge this and cheer it on least we get so caught in a false sense of doom that we just give up.
Its not good news at all, electricity prices have gone up a lot since this net-zero insanity took over. Morons are clapping their hands like trained seals at their bank accounts being drained by corporations and politicians.
All prices have gone up in the same window you describe!
This is due to corporate greed. Solar and wind are the cheapest sources of energy in the history of the world.
That's very surprising, in a good way.
I'd be really curious to see the dollar per kilowatt hour on each one of these.
60% of US electricity still isn't emissions-free
This is the best summary I could come up with:
But some of the trends now seem locked in for the year: wind and solar are likely to be in a dead heat with coal, and all carbon-emissions-free sources combined will account for roughly 40 percent of US electricity production.
Weather can also play a role, as unusually high demand for heating in the winter months could potentially require that older fossil fuel plants be brought online.
This is in keeping with a general trend of flat-to-declining electricity use as greater efficiency is offsetting factors like population growth and expanding electrification.
Its output has been boosted by a new, 1.1 Gigawatt reactor that come online this year (a second at the same site, Vogtle in Georgia, is set to start commercial production at any moment).
But that's likely to be the end of new nuclear capacity for this decade; the challenge will be keeping existing plants open despite their age and high costs.
The explosive growth of natural gas in the US has been a big environmental win, since it creates the least particulate pollution of all the fossil fuels, as well as the lowest carbon emissions per unit of electricity.
