I like design and building stuff with no-code tools. Into energy and climate, sports, stuff outside.

@AdamSinger I’m all for solar and batteries but you should run power to it if you can. To go truly off-grid for the whole year you’d have to significantly over-size the PV and battery system for outlier events- so it still works during heat waves and long cold snaps

Get a mini split plus ERV

https://t.co/vWyZNtz27l

[John @lerchJE]

@bytecrafter_1 @levelsio Bump to this. ERV/HRV is the way to go. Don’t event need it on a sensor, just let it bring in fresh air efficiently on a timer 45min on / 15 min off.

@ben8128 Loved the series on coal. Looking forward to this one

@JessePeltan Is anyone going after this space?

The use of primary energy on the vertical axis is an old trick by the fossil fuel industry to mislead people into thinking that one unit of fossils = one unit of renewables. In fact, one unit of primary energy for wind or solar electricity is the equivalent of three units of fossil fuels for electricity.

Another trick is to pretend we need all those fossils if we switched to renewables. In fact, if we switch to renewables, 12% of the fossil fuel energy disappears because that is how much energy is used to mine-transport-refine fossil fuels+uranium for energy, and we wouldn't need to do that anymore

A third trick is to pretend we need so much energy if we go to all electricity powered by renewables. In that case, because EVs use 75% less energy than gasoline/diesel vehicles, heat pumps use 75% less energy than combustion heating, etc., energy demand goes down another 42%.

In sum, this plot illustrates the real story of where we are and where we need to go. The proper metric is end-use energy, not primary energy.

@everestchris6 Roof

[Chris @everestchris6]

this OpenClaw bot finds warehouses with old roofs, renders solar panels on their actual building, and books the owner a call, all on autopilot...

here's how commercial roofers can close $2M+ deals before the solar tax break ends:

- scans thousands of commercial roofs via satellite
- scores each building by roof age & urgency
- pulls exact panel count from Google Solar API
- finds the real owner (not the property manager)
- calculates their federal credit to the dollar
- renders a video of panels materializing on their roof
- ships a personalized proposal
- fully automated end to end
every day that passes is money off the table.

reply "ROOF" + RT and i'll send you the full breakdown so you can build this too (must be following so i can DM)

.@fervoenergy signs deal with Turboden for 1.7 GW of 50 MW "geo blocks," standardized organic Rankine cycle power plants. Standardizing and scaling surface plant manufacturing is a key driver of the experience curves we expect to see driving down enhanced geothermal costs as the technology scales, as detailed in prior ZERO Lab research led by @wilson_ricks https://t.co/Tm68Ph9fFy

In less than a year, we managed to get more than 13M organic views on Reddit.

It brought over 100,000 people to our website without spending a cent.

We put together a Reddit Strategy Playbook that gets me 1M+ organic impressions/month… and makes my posts show up consistently inside AI outputs (ChatGPT, Gemini, etc.).

Here’s what’s inside the playbook:

😈 How We grow my SAAS gojiberryAI with Reddit

🔥 The 3+1 post formats that always go viral

🚫 How to get traffic from 100 subs → without getting banned

🔎 Our Reddit SEO method to rank in AI-generated answers

⚡ The automation flows we use to convert views into demos

🏴‍☠️ A little bonus just for you

Want the full 1M Views/Month Reddit Strategy (100% Organic)?

Here’s how to get it:

✅ Repost this post
✅ Comment “REDDIT”

I’ll send it straight to you.

Google is now the first cloud provider to integrate 1 GW of flexible demand into long-term utility contracts. Our ability to shift or reduce our energy demand when it’s needed can help utility companies balance supply/ demand and plan for future capacity needs.

This is a big milestone for responsible data center growth and helps keep costs lower for local communities.
