It’s already irreversible, but it’s just disappointing to see how the U.S. administration has chosen to actively fight against it, while other countries like China are embracing reality.

It’s actually funny if you don’t think about it too hard. The U.S. president is trying to make us more reliant on fossil fuels, while starting a war in Iran that’s led to the global fossil fuel market to be negatively impacted, forcing most Americans to pay more for fossil fuels. Who could have seen that coming? We’re doing great!

Yes. But administration opposition can change that math, as they have with the tariffs.

some-guy•26m ago
Both NEM 2.0 and 3.0 have serious issues, but for different reasons. NEM 2.0 was basically a early adopter's rich person's subsidy that heavily distorted the market, and NEM 3.0 does not have nearly enough subsidies to justify the cost unless you pay cash up front for a large system. (For the record, I am on NEM 3.0 and got such a system).

At the end of the day, the best case scenario is large scale renewable / battery storage to bring costs down as much as possible, and for those of us who want battery backup / solar can choose to invest in it, but it shouldn't be "the" solution.

To be fair (and, somewhat ironically, rationally detached libertarian) that's the way it's supposed to be. We don't develop and deploy technology to make a bunch of too-online nerds rich.

(personally I like both but I can see some shortcomings - for example I have heard that ai datacenters are using gas at times because of its flexibility)

So what are some of the best talking points to "sell" solar and wind to the unconvinced?

Or will they just adopt it once it's seen everywhere?

mrhottakes•43m ago
If people have strong opinions about renewable energy, just don't waste your breath. You can't reason someone out of an opinion they arrived at unreasonably.
jahnu•30m ago
Keep hammering the point that they are cheaper. If they are open to more advanced discussion point to the amazing structural changes that batteries are only starting to bring. Tell them something that sounds mildly like science fiction but is in fact happening already and will be HUGE. E.g. the battery you’ll have in your AC/stove/car will save you money or even make you money when part of a smart mesh of DERs.

Maybe I’m too optimistic :)

mrhottakes•25m ago
"It's cheaper" is a good route, but a lot of these people have decided they don't care about objective facts in favor of what their favorite media personality says.
WarmWash•12m ago
Let me preface this that I am a huge advocate for renewables, and have been spending borderline unreasonable amounts on turning my home green.

The rub with "solar is cheaper" is that those values are almost always calculated using an ideal environment. Solar is cheapest when you are using flat barren land in Arizona where an acre costs $500, the sun shines 330 days a year, you are bulk buying 750 MW of panels, and the bureaucracy is a single rubber stamp. Those are the numbers that ultimately trickle to headlines.

Things get much more complicated (read: expensive), when you are in the North East, an acre costs $12,000, the sun shines 170 days a year, you're bulk buying a few dozen MW of panels, and the bureaucracy is 6 different government bodies full of permits and assessments.

In that situation, a gas plant that produces 10x more power on 10x less land becomes very appealing to people who are already getting crushed by soaring electricity bills. (My take: we're just going to have to deal with higher costs).

So I am all with you on abandoning fossil fuels, but to someone who is firmly in gas camp, they will have legitimate ground to stand on when balking at costs. "It's cheaper" is unfortunately not all encompassing.

blackjack_•19m ago
Multiple ways. One interesting one is huge sand batteries that are being heated up to massive temps, then having pipes run through there to collect the heat energy as hot water and doing the industrial processes that way.

Another way is using excess green energy to produce green hydrogen, which can be used as a fuel source in very high energy scenarios.

Past that, we recently have made electric arc furnaces and electric smelting furnaces for steel and aluminum, and several of these are fully solar powered.

It’s a shift to change the energy source for industrial production, but we have the technology and the ability. And the sun is free!

China having managed to position itself as the main driver of the green transition by investing into key industries illustrates the power of state planning.

*electricity . Gas is heavily used for heating , cooking & industrial uses (e.g. drying agriculture like hops, boilers etc).

I raise this point since policymakers get confused and try to ban gas, only to realize how critical gas is for food & industrial applications that consumers enjoy after the fact.

PaulDavisThe1st•5m ago
You're correct that this ought to say "electricity" and not "power".

But I think you're wrong to think that gas is "critical" to any of the things you've listed. "Currently used" ... yes. "Not replaceable by electricity" ... no (unlike, e.g. air travel).

philipkglass•9m ago
More good news from Ember, according to their Global Electricity Review 2026 [1]:

Solar power increased by a record 636 TWh to reach 2,778 TWh in 2025, a 30% increase from 2024.

Wind saw the second-largest increase, growing 205 TWh (+8.2%)

Driven by record solar growth, low-carbon power generation increased by 887 TWh in 2025, outpacing electricity demand growth of 849 TWh. Solar power alone met 75% of the net increase in electricity demand. Together with wind, the two sources met almost all (99%) demand growth.

For the first time in 100 years, renewables (33.8%, 10,730 TWh) overtook coal power (33.0%, 10,476 TWh) in the global electricity mix as continued rapid growth in solar and wind pushed the share of renewables above a third of global generation. Coal power dropped 63 TWh (-0.6%) in 2025, marking the first fall since the Covid-19 pandemic in 2020. Combined with continued electricity demand growth, this meant coal fell below a third of global generation for the first time in history.

For comparison, I have collated information from the International Atomic Energy Agency's Power Reactor Information System. The fastest that nuclear power generation ever grew was 213 TWh added in 1985. Since the year 2000, the fastest growth year was 2004, with 111 TWh added.

mtmickush•7m ago
This is exciting news but the term power here should really be replaced with electricity which is clarified early on in the article.

Electricity only accounts for roughly 20-25% of all power / energy used and the vast majority of the remaining 75% is fueled by gas (cars, ships, heating, construction, ect.)

Tade0•3m ago
That is true, but a lot of that, if replaced by electricity, would use considerably less energy overall, so it's not a 1:1 comparison.

Residential heating in particular would use anywhere between a third to half the energy, if we only transitioned to heat pumps.

nielsole•2m ago
Important to consider that your stat is likely comparing primary energy, not secondary energy. E.g. an electric car or a heat pump use less primary energy than the fossil equivalent.
Wacari•2m ago
no. if you work in the industry you'll know power/electricity are used interchangeably, and energy is treated as the superset.

And roughly 2/3rds of that is lost as waste heat, so really only another 25% is actually useful.

I mean, there is money to be made. CATL stock (the major producer of EV batteries with 50% market share, with billions of contracts for stationary batteries) rose 48.81% over the last 6 months, for example.

But I agree that news about renewables goes unnoticed. I only see news about renewables because I actively seek out channels and websites that cover it. I wonder if it is because most companies in the industry are Chinese and don't focus on PR in the West as AI companies do.

Every kWh your panels make from sunlight that you use immediately (or store "behind the meter"), you don't have to buy from the grid.

In fact, it's very easy to reason them to change their minds:

1. Take statistics from any of these excellent solar power plants for, say, five years time span

2. Find the worst week in terms of energy production in these statistics

3. Explain to the renewable energy skeptic how this 20+ times drop in productivity will be compensated for users

4. The skeptic is successfully convinced and becomes a renewable energy proponent

tialaramex•25m ago
> some places it doesn't

I can see this for wind, but not solar. PV turns sunlight into electrical energy. The whole damp rock gets sunlight on the outside, why not build panels anywhere?

For wind yeah, if you live one of those boring flat places which gets tornadoes a wind turbine is definitely a bad idea, it won't make much energy and then a tornado turns it into scrap and possibly destroys nearby things with chunks of debris.

I believe this is one of those having your cake & eating your cake scenarios.

Because there's better alternatives same places. Norway has legendary well-suited topography for hydro power (>90% of electricity), and it's reliably windy (>8% of electricity). It's also so far north that the sun doesn't shine very much for half the year, and it's notoriously cloudy.

So yes, it will probably never make much sense to build a lot of solar panels in Norway. Same for Greenland, Iceland (substitute geothermal), and probably some parts of Canada, Alaska and Southern Argentina.

But also, yes, there's almost nobody living in those places. They're not terribly relevant in the grand scheme of things. Probably significantly less than 50M people in total.

wat10000•6m ago
Tornadoes are not actually very common in terms of how often you'd expect a structure to be hit by one. You're looking at hundreds or thousands of years between tornado hits even in the most tornado-prone areas. They're numerous, but small.

I spent a good chunk of my life in the Pacific Northwest. You get very long stretches of cloudy skies through most of the winter that are poor for solar. However, there are alternatives in that region like hydro that may be more suitable choices.

You need to include batteries in the equation: solar, wind, water and batteries.

What California and others have shown is that you can replace natural gas peaker plants (literally - tear out natural gas turbines) with batteries and get both superior cost dynamics and "dispatchability" (aka turning them on and off). Batteries have millisecond level dispatch, peaker plants have hours level dispatch.

There's a lot of selective concern.

PyWoody•7m ago
> They'll be outraged about the environmental damage from mining and manufacturing needed for panels, but ignore the orders of magnitude worse damage from burning fossil fuels.

I always try to point out that, after all of the "environmental damage" done to create the solar panels, the panels will exist for 30 years before they can be recycled into new panels. Whereas, after all of the environmental damage done to produce gas and coal, it will lead to a one time use only energy output that has to be repeated until the end of time.

It makes zero sense environmentally or cost-wise to prefer fossil fuels.

dimitrios1•5m ago
I am against it for one reason only, but it's very solvable, IMO, and it's the amount of space they take up.

I live next to 200+ acres of solar farms. A part of me cries a little when I see so much beautiful land and trees cut down and these lifeless panels taking up so much space. We have so many buildings, and structures already (think parking decks, tops of apartments, homes, offices, even parking lots) that we could put these, but instead we cut down acres of trees or use up perfectly usable farmland.

Kon5ole•4m ago
>I don’t know how you can be against solar unless you’ve been given some uninformed talking points.

One understandable (not saying it's good, just understandable) reason is if your business is selling electricity from a source more expensive than solar. Which is just about every source.

I think power producers will eventually have to combine power generation with activities that generate money separately from selling electricity. Like heavy industry, datacenters etc.

The problem is every good argument for renewables will always inevitably have someone come up with some kind of counterpoint that on the surface may seem reasonable to those without the time or inclination to deeply research it all.

Energy is complicated.

FWIW I agree with a sibling poster who said to just say "its cheaper".

- cheaper - much less upfront capex, lower operating costs

- removes nasty geopolitical dependencies on eg gulf state oil and gas; costs are more predictable

- easier to plan and build because the base units are much smaller

Variability remains a valid objection, to which the main answer today is "batteries. Lots of batteries. And other cheaper longer duration storage, like sand heat storage, vanadium flow, and good old pumped hydro."

let me guess... they sell oil?

Increasing utility energy prices worked for me. I wasn't anti-solar, but it didn't seem worthwhile for me. When the utility price doubled over three years (or just about), the math makes sense now. I'm not looking for solar to acheive grid independence though, I already have a whole house generator for that, because utility power is two nines reliable around here.

We have already reached the point where solar and wind produce new MW of power cheaper than any other power source you can build.

Of course that energy generation comes with the caveat of being variable with sun and wind. It can still be a net benefit to the grid but the variability means alternative energy sources are still needed.

The cost trend of installing solar/wind plus enough storage capacity to provide steady grid power will eventually cross over to also being cheaper than other sources of energy. At which point the only reason to be against it is if you prefer artificially subsidizing another energy source.

A few different things would help.

First would be to be clear and unambiguous when it comes to building gas/oil thermal power plants in order to deal with the intermittence problem of solar and wind. Political strategies in wind and solar is built on trust, and people will quickly become unconvinced when politicians are dishonest/ambiguous about the requirements that is needed to support a grid with a high ratio of wind and solar.

Using fossil fuels as the reserve energy for when the weather is bad allows the producers of reserve energy to demand high market prices, to the point where a whole month in EU can cost as much as a full year. Even if solar and wind would put the grid costs to zero for 90% of the time, it doesn't make the cost for the consumer any lower if the fossil fueled "reserve energy" can increase their price by 10x. Selling solar and wind require some kind of solution here.

Reserve energy also want to be paid if they are expected to stand-by 365 days a week, which is a big reason why EU subsidizes to fossil fueled thermal power plants are not decreasing when the ratio of wind and solar goes up. That costs is then added as a grid fee/taxes, hiding the true cost. Paying first to keep the fossil fueled power plants warm and ready when solar and wind is producing, and then pay them a second time for whatever the market price is when they are producing is a very costly way to operate a grid.

And last is the transmission costs. Switching between multiple different energy sources depending on the weather has a high demand for a very flexible infrastructure in terms of transmitting energy from where it is being produced to where it is being consumed. In south of Sweden as an example, the cost of transmission infrastructure and the cost of reserve energy is now the majority of consumers electricity bill, with cost associated with production of energy being a small minority.

Solving those issues is what will convince people of the viability of wind and solar.

You can't "sell" the opposite to someone who is expressing a loyalty belief. If their tribe believes in the opposite, then no amount of logic will change their minds - only a change of their or their group's allegiance will change their minds.

Ensure that the prices decrease for people with existing contracts. The hatred comes from people being told that it's better and cheaper now while the price is significantly higher than before.

If I didn't have solar panels on my roof that basically cover all my energy needs, I'd be absolutely furious seeing politicians pat themselves on the back for shutting down nuclear power plants and talking about how energy is now cheaper at some foreign exchange where I can not buy while I pay more and more every month.
