Behind Everyday Energy
Six short courses in the physics of energy and one table of units, assembled from what NASA, NIST, the Energy Information Administration and a few university departments publish for the public.
A word on the address
Physicists like to say that nothing about energy is magic, yet a kettle boiling on electricity made by spinning magnets a hundred miles away still feels a little like it. That feeling is the only magic intended. The web address once belonged to an unrelated practice; this site is about physical energy, not energy healing, and it has no connection with whoever ran the earlier site.
What is on the shelf
| Page | The idea it follows |
|---|---|
| Forms of energy | Potential and kinetic energy, and the everyday forms within each. |
| Conversion and conservation | Why energy is never used up, only changed, and what efficiency measures. |
| Sunlight and radiant energy | Fusion in the Sun, light as waves and photons, and the spectrum. |
| How electricity reaches a home | Electrons, generators, transformers and the grid, in order. |
| Energy at home | Power versus energy, the kilowatt-hour, and estimating appliance use. |
| Energy in food | The calorie as a unit of energy, in joules and in everyday terms. |
| Units table | Every unit and conversion factor on this site, in one table, with its source. |
Every quantity here can be measured in joules. Anything called "energy" that cannot be is left alone.
Who it suits
Someone who has seen "kWh" on a bill or "kcal" on a cereal box and wondered what either one really counts. Arithmetic is enough; formulas come with a sentence saying what they mean and a worked example with invented round numbers. Because most of the documents behind the guides are American, the household examples use 120 volt sockets and the British thermal unit. Joules behave the same in every country.
How the pages were put together
An AI system wrote the drafts, with the documents listed at the end of every guide as its raw material. Those documents come from the Energy Information Administration, NIST, NASA, Virginia Cooperative Extension, Penn State's College of Earth and Mineral Sciences and a Gettysburg College physics text hosted on LibreTexts. On 2026-10-26 a script downloaded each of them once and looked for the specific facts the guides borrow; the checking page gives the numbers and the gaps.
No person has edited these pages, and no physicist has read them. Where a guide and its source disagree, believe the source.
The pictures are vector drawings written as code, by hand: a sun, a pendulum, a meter on a wall. They are diagrams, so they show no actual product, building or person.
Left out on purpose
- Shopping of any kind: no store, no affiliate links, no brand names, no sponsored pages, no adverts.
- Ties to a power company, appliance maker, retailer or public agency. There are none.
- How-to steps for wiring, repairs or installing equipment, or any engineering judgement.
- Diet and health advice. The food guide stops at what a calorie measures.
- Cookies, analytics and tracking code.
Getting in touch
You can't, for now. The site has no form, no email address and no phone line. Should a way to write in ever be set up, it will be announced on this page first.
