Everyone is getting tired of me checking the panel to see how many watts we're bringing in.
Next project, install a shunt and get a Raspberry Pi talking to it over USB. And then I'll be able to build a Grafana dashboard. :)
(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?
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.)
What I mean is say the grid demands 100. The grid is powered entirely by coal. You give it 120 for 20% redundancy. This is extremely reliable.
The grid demand is now 120. You now need 144 for 20% redundancy. You dont want to use coal. So you add solar and batteries.
Batteries are great because they normalize the volatility of solar generation over time, but they do not make solar truly on demand. So if you add 24 solar to the 120 coal you are increasing the risk on the grid. What often happens is you add 24 solar but you have 24 coal as a backup. Ideally the real-world use will be solar but in case of downtime your grid will not fail.
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.

the spite is the point
(do we survive past 2029? are you sure? I'm not)

One of the short-term issues in the US is going to be that a lot of utilities depend on natural gas and natural gas prices are going to keep rising beyond whatever happens in the Persian Gulf because of increased LNG exports (that directly raises domestic prices) and the increased use of gas turbines for AI data centers. Plus all the consumers are going to pay for the infrastructure buildout for electricity for those data centers.
So, despite a large Y/Y solar increase in the US, electricity prices are only going up.

Incredible gobsmacking amount of stored energy on display here. Great to see. https://bsky.app/profile/neilgrant.bsky.social/post/3mneo3to...
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.
China gets it, the USA doesn't.
I want to feed the balcony solar o/p back to the grid and not have a off grid system
Meanwhile I bought a 25W solar panel and a controller and am going to make a solar charger to charge my powerbanks
