# Greenhouse - Lighthouse, but for web that doesn't use fossil fuels

Lighthouse is a nice tool for helping you workout how to make a site more accessible, performance or mobile friendly.

But given climate change is a thing, what about making websites planet friendly too?

### The general plan

- Point lighthouse at a url.
- Analyse the rendered page
- See which domains in use run on renewable power, by checking against the Green Web Foundation API, or seeing what's returned at `carbon.txt`
- Compile this info into information you could present in a lighthouse run, so tools that provide lighthouse as a service can _also_ do this.

### Usage

```
node index.js https://domain.com/some-page/
```

This will generate a file, `lighthouse-check-output.json` listing all the domains, as well as whether each domain referenced in the site is green, or grey.

### Other bits that would be cool

If take a second to consider that sending data users servers and networks, which use electricity, which is mostly generated by burning fossil fuels, then it means that *page weight budgets are defacto carbon budgets*. Yes, there is a moral argument for WPO!

Also, so we know that a site we can to connect to can be green or not. But what about the hops in between?

Try this:

```
node tracingCheck.js domain.com
```

It'll create a json file, called `domain.com-latlngs.json`, showing the hops along the way, and whether they're green or grey.

Make this an actual custom audit for lighthouse

After reading up a bit more, I think the proper way to do this is make this custom audit, so the checks on domains can be presented using the cool scoring thing, and people can incorporate it as simply as calling npm install some-greenhouse-npm-thingo.

This tutorial outlines the steps:

But…

Every time I tried making this, I've missed something obvious, and the way I'm looking through the artefacts in the code seems to be different to what the custom audit suppports.

But I'm pretty sure it can be done, and it shouldn't be all that complicated (hoho)/
