Like I said he grossly understates the energy demand we use in the United States for heating during the winter.
I believe a lot of that demand is due to there being no incentive to increase energy efficiency.
Fun fact, 12 million hectares of land of used to produce corn used for ethanol which is used to produce gas. I'll let you draw the conclusion. https://news.cornell.edu/stories/2025/04/trading-some-corn-e...
The article is just wrong. And only mentions energy used for heating in passing. Heating requires MASSIVE amounts of energy. I should know bc I have a whole house battery and solar system (almost 30 kWh battery and 24kW solar). It keeps the lights on, but not heating. I live in a mild climate. The reality is that battery/solar requires major quality of life and activity time shifting trade-offs.
I don’t know where all that energy was going. I expected some improvement but not anywhere near that much.

People still build houses like energy is cheap and abundant. A properly insulated house in any temperate climate require very little heating or cooling. Spend 50k on insulation that will last the life of the building instead of 50k on heating and cooling devices which will need constant maintenance and replacement + fuel and end up costing 10x more over the life of the building. A modern house with modern insulation…
Yes you're right and I don't disagree. But a 500w heater isn't going to cut it when it's 20F outside. You actually have to run the heat as hard as possible when the sun is shining so you have some thermal momentum going into the evening. The end result is you're going to make big lifestyle changes to accommodate the energy. For example everyone sleeping in 1 bedroom and only cooking with an electric pressure cooker o…
There are passive houses built at 2000m altitude in the Alps, some are made of wood and have literal strawbales for insulation, there are no excuses left in 2026 not to build good houses, it's more economical, more practical, more comfortable, more ecological

I live in a northern climate and I know multiple people who are net zero with solar+basic battery. Proper insulation and good windows go a very long way. For instance, I set my heat to 66F during the day and 60F at night. When I wake up in the morning, the register is usually still above 60F.

Net zero. But not effectively zero. They sell energy during the day when no one needs it and buy it an night when we all need it. If we all switched to solar and heat pumps there would be blackouts and an energy crisis
What? They store the surplus in their batteries during the day and use it at night. I genuinely do not understand why people are so afraid of solar. It's baffling.

> I should know bc I have a whole house battery and solar system This is not really a qualification to speak on how the grid works, at all. Actually having panels on your roof doesn't give you unique insight into how solar panels operate - there is extensive data out there, any PV installation can become a data source trivially. > The reality is that battery/solar requires major quality of life and activity time shif…
What about STORING excess power and delivering it during the day at a same level ? That is a critical part! I remember last time it was too expensive.
