Among other devices, Keelog sells a line of replacement power supplies for retro computers, from the Commodores to Amigas to Ataris. They are all brand new designs engineered with longevity and safety in mind.
This is a little sun powered board with ultra low power consumption and zero maintenance. It measures temperature, humidity, pressure and sends it every 15 minutes with a RF module. The small solar panel (8 x 6 cms) harvest energy to charge two small and cheap super capacitors of 5F each. It can run alone almost forever, at least until the caps die. But supercapacitors have a much longer lifespan than batteries. It can survive without sun about 80 hours, more than 3 days! I tested it with the solar panel disconnected. This is also environmental friendly as it produces it's own energy and don't use batteries with it's 'dangerous good regulations' (DGR) for handling, disposing, etc.
It seems like this project would be a good way to learn about using supercaps to run things.
PowerOutage.us is an ongoing project created to track, record, and aggregate power outages across the United States. This site has tracked some major events, including hurricanes, grid failures, and other weather events. You can view some detailed information about them here.

Data is updated site wide approximately every ten minutes.
They have a REST API but there is no free tier.
It's not that other energy monitors are bad, but they are different in that they are mostly closed systems that provide limited data and require that you use their cloud and phone app platforms. IoTaWatt collects many more metrics and stores that usage history locally. With it's integrated web-server you can manage setup, view real-time status or create detailed graphs using the browser on your computer, tablet or phone. It's your data, in your own home, and subject only to your own privacy and retention policy. You don't need the cloud to get a handle on your hot-tub, EV, solar or heat-pump.
IoTaWatt can, however, easily upload usage data to any of several third party databases with associated apps and analytic tools. For instance PVoutput is a free service that connects easily with IoTaWatt and provides world-class solar energy analytics. There is full support for uploading to influxDB. There is also an API interface for those who want to query data for their own applications or to use in spreadsheets, and there are integrations available for home automation software like Home Assistant.
Can be used to monitor just about any power system on the planet. USian 120/240VAC, European, 230 VAC single-phase, 230VAC three-phase in Australia, Germany, and Norway.
IoTaWatt measures each circuit using a passive sensor that clips around one of the insulated wires. The output of each of these current-transformers is very low-voltage and plugs into any one of IoTaWatt's 14 inputs. Sensors plug into the unit with regular phono plugs.
Fully tested and in compliance with regulatory and safety standards of North America and Europe.

If you only want to monitor power for the whole house, you only need the base kit and two induction sensors (one for each side of the split-phase). $260us
Automatic CPU speed & power optimizer for Linux based on active monitoring of laptop's battery state, CPU usage, CPU temperature and system load. Ultimately allowing you to improve battery life without making any compromises.
One of the problems with Linux today on laptops is that CPU will run in unoptimized manner which will negatively reflect on battery life. For example, CPU will run using "performance" governor with turbo boost enabled regardless if it's plugged in to power or not.
Issue can be mitigated by using tools like indicator-cpufreq or cpufreq, but these still require manual action from your side which can be daunting and cumbersome.
Using tools like TLP can help in this situation with extending battery life but it also might come with its own set of problems, like losing turbo boost. With that said, I needed a simple tool which would automatically make "cpufreq" related changes, save battery like TLP, but let Linux kernel do most of the heavy lifting. That's how auto-cpufreq was born.
Please note: auto-cpufreq aims to replace TLP in terms of functionality and after you install auto-cpufreq it's recommended to remove TLP. If both are used for same functionality, i.e: to set CPU frequencies it'll lead to unwanted results like overheating. Hence, only use both tools in tandem if you know what you're doing.

The California Independent System Operator (ISO) maintains reliability on one of the largest and most modern power grids in the world, and operates a transparent, accessible wholesale energy market. The organization works diligently around the clock to meet the electricity needs of consumers, while increasing the amount of renewable energy to usher in the clean, green grid of the future.
The California ISO provides open and non-discriminatory access to the bulk of the state’s wholesale transmission grid, supported by a competitive energy market and comprehensive infrastructure planning efforts.
Things of interest: Emergency notifications, daily briefings, API, power grid status, and electricity pricing.
I really need to figure out how to monitor this.
Open Infrastructure Map is a view of the world's infrastructure mapped in the OpenStreetMap database. This data isn't exposed on the default OSM map, so I built Open Infrastructure Map to visualise it. If you want to edit the data and you're new to OpenStreetMap, check out learnOSM.
If you already have some OSM experience and want to start tagging infrastructure things, take a look at the tagging guidelines for power and telecoms.
How to configure later-generation nVidia drivers to do their own power management now that it's supported on some models.
Applicable to Turing GPUs and Coffee Lake CPUs. Windbringer does not have the former (the GTX 1050Ti is a Pascal architecture, not a Turing architecture). Still, there are options.
This is the PSU board for all your retro modding needs like making a GameBoy Zero with any of the Raspberry Pi products and it’s Clones like Orange Pi, Banana Pi etc, it has even powered Robots. This board has all the features the modding community wants and needs for their build into a small and powerful package. Outputs up to 6A @ 5.20v. i2c enabled, so the power cells can be monitored.
This project is a software defined radio receiver for these messages. We make use of an inexpensive rtl-sdr dongle to allow users to non-invasively record and analyze the commodity consumption of their household. Designed with ERT-compatible smart meters i mind.
A python tool to shutdown your computer by removing an USB device. Originally intended to be run on RaspberryPi to prevent brutal shutdown.
A set of scripts for Retroflag's RasPi cases that make the power and reset buttons functional in ways considered safe for live Linux machines. Requires the GPIO pins.
Be sure to follow the instructions for the correct Retroflag case!
