So the increase was 3.1% and it was "fourth largest in the last decade", which means, "barely above average growth rate". Considering that economy growth rate was the fastest in a decade except 2021 which was a covid recovery year, it doesn't really show anything abnormal at all.

All that work and we still have a broken economy, go figure.

What's broken about it?

It's easier to coordinate N electricity suppliers when N is small.

My point is that scaling coordination issues exist for everything, including all sources of energy production. Singling out solar and continuing to not prioritize it will inevitably lead to ongoing grid issues. Whereas this has been mostly solved for other sources, due to lobbying and legacy. Thus my confusion about the OPs half-baked point.

If you go up the thread, this is the context we're in:

"Solar can be deployed by hundreds of thousands of individual efforts and financing at the same time, with almost no bureaucracy."

N>100000 is a lot harder to coordinate than the ~15,000 established power plants, which have come online over the last hundred or so years.

We are indeed living in more comfortable homes. Americans are migrating to the sunbelt because of ample AC in the summer and the winters are pleasant. that’s a big part of why we have many fewer heat deaths per capita than Europe: https://www.thetimes-tribune.com/2025/08/02/opinion-us-heat-...

Europe is so backwards when it comes to annual heat deaths that they manage to have more heat deaths per year than the US has gun deaths + heat deaths combined. You won't hear about that from Europeans though, it'd make them seem barbaric. 175,000 heat deaths per year in Europe according to the WHO. It's a staggering genocide of technological primitiveness. Imagine having millions of people die because you can't be b…

You sent me to the books because this is such a fascinating stat. It's true! Heat deaths in the US: 5 per million people. Italy: 500+ per million people. I had no idea.

Solar is highly distributed. At the most basic level with a solar & battery system the production and consumption and CONTROL are all yours. You own it and it's literally on your property. Refinements on ways to sell it to neighbours / recharge various EV's / use it for new purposes are all up to you. There are lots of analogies to self hosting or concepts around owning and controlling your own data, when it's owned…

Cost. Useful life. I thought about an off grid system. Batteries are expensive. Also, unless you live in a dry place in the equator, You'll need to account for things like winter, long rainy spells, so either you add more batteries to account for multiple days (weeks? months?) of low generation, or you'll need a diesel/gas generator, or have a hybrid system instead, which basically means you're using the utilities ga…

No need to go off grid. You getting solar and battery already positions you to be able to ‘exit the grid’. The experience in Australia has been that the major retailers keep charging infrastructure costs to those who still rely on them. The mass of solar adoption grid and off-grid shifts the playing field.

What is NG good for? Induction cook tops perform better than gas ones, heat pumps do better than gas heaters. The only gap I can think of are just in time hot water heaters.

Gas cooktops are good for still being able to cook when the power is out.

I am not sure where you live, but I cannot remember the last time our power went out (Western Europe).

I have gas-cooked since I was a kid (living in an area with a lot of natural gas, so houses were connected to gas since the 50ies), but induction is so much nicer that I'm happy to not be able to cook during a once in a ~10-20 year outage. Also a lot safer (it still happens quite frequently that a house blows up because of a gas leak, just this week there was a huge explosion in Utrecht what was presumably a gas leak).

Of course, the equation may change for countries with less stable power.

> the fourth‑largest annual rise of the past decade Really doesn't sound like much of a surge then!

Hey, that still means it's higher than the median annual rise AND higher than most years!

> higher than the median annual rise

Of that we cannot be sure... Because maybe 6 years saw a fall - so there would only be 4 rises, of which this is the smallest!

Did "demand surge" or was excess peak power sold of for nearly 0 to people that can spin up and turn off load on the turn of a dime (crypto)? We have had negative pricing (they pay you to take the power) to stabilize the grid due to solar/wind peaks.

In Vancouver, Canada natural gas was completely phased out as of the beginning of 2025 in most new construction.

What is NG good for? Induction cook tops perform better than gas ones, heat pumps do better than gas heaters. The only gap I can think of are just in time hot water heaters.

I think NG outperforms in high efficiency heaters when the outside temperature is around 1-4 degrees Celsius with humidity as it causes ice buildup on the external unit which then has to be cleared using resistive heating. Also if only little hot water is required sporadically, heating it just in time with gas is more efficient than keeping a buffer heated for long times.

Also, heat pumps do best when the temperature differential is lower. So in older housing without floor heating or duct heating, it is typically not as efficient to use a heat pump when the water to heat has to be above 55 degrees Celsius.

For any new residential construction I think there is very little value in natural gas.

Gas cooktops are good for still being able to cook when the power is out.

Batteries or Generators don’t just let you cook and stay warm when the power is out but do everything else such as keep food cold as well.

We see that quite often here in the summer as the energy price sometimes drops to minus 60ct/kWh (more often it hovers around -5 to -10). It is pretty much "please use everything now" to avoid grid issues. It often happens on very clear days with lots of wind.

Mine bitcoin, run LLM inference, smelt aluminum, make synthetic fossil fuels from atmospheric CO2.

The problem is the capital cost of any of that type of equipment sitting around idle or under-capacity, ready to go when the electricity price goes down. It's likely more profitable to run them most of the time, even with positive electric rates, and then only stop using them when rates are exceptionally high ("load shedding").

This is why you see most opportunistic electricity consumption systems doing resistive heating - this equipment is inexpensive.
