Green hosting: what the bar shows

Your website is on 24 hours a day, so it uses power 24 hours a day. At Daylit that power comes as much as possible from our own solar panels: directly during the day, at night from our own battery, which we fill with solar power during the day. Only when the battery is empty do we use power from the grid. The bar on the homepage shows how that went, hour by hour.

What the colours mean

Green: sun. Power that came straight from our solar panels.
Yellow: battery. Solar power from earlier that day, stored in our battery.
Red: grid. Power from the grid, when sun and battery were not enough.
Grey: no figures for that hour (yet).

Each block is one hour of the day, from 0:00 to 24:00. A block can have several colours: in the evening it is often partly battery and partly grid. Point at a block for the exact split. Once there is a full week, month and year of measurements you also see the average per hour over that period.

Honest about the grid

We do not claim to run on solar power all the time, because we do not. In winter the sun is short and weak, and after a long night the battery is sometimes empty. Then you see red in the bar. We do not buy certificates to make that power green on paper: what you see is what really happened.

How we measure

Meters record every quarter of an hour how much power came from the solar panels, the battery and the grid.
We split the power our servers use over the sites running on them. In My Daylit you see per site how much energy it uses and where it came from.
On the website we only show percentages: how much of the power came from sun, battery and grid.
For the CO₂ of grid power we use 200 grams per kWh (the average Dutch power mix). For comparison we count "ordinary hosting" as a data centre on grid power, with the average extra cooling and losses of data centres.

Why choosing on purpose helps

Hosting is invisible, but not free for the climate. Choosing a host that shows where its power comes from makes it visible and gets others thinking. You can show it too: with a green site at a fair price, without teaser prices.
