Intermittent data centres
<It is possible to power your data centre partly or completely by green power without having to make a massive investment.>
Not without backup plant to run it when the wind don't blow and the sun don't shine.
<Hosting provider Memset has, for example, opened a new facility on Dunsfold Park in Surrey – a business park powered entirely by green energy, which gets on average 37 per cent of its power from the sun, delivered via the grid.>
Bollocks. Double bollocks in fact.
First, this a patently untrue statement unless they have their own "personal" grid connected only to renewable sources.
Otherwise they're just pulling power from the grid in whatever mix happens to be co-generating at any given moment. Which leads into the second "bollocks". Even if the provider billing them has dedicated connection to solar generation with a nameplate capacity totalling 37% of the power used by the business park, the business park will not be supplied by 37% solar power at any time, ever.
They are connected to the grid like everyone else. Whoever bills them has fed them some bullshit to make them believe that all of the power they use will come from "green" sources, and they swallowed it saying "please, Sir, may I have some more?"
