(Also, this would cost A LOT!, It would be much better if they removed setup fees. and helped the customer.

They could however, outsource and offset their carbon by building wind turbines elsewhere, which could easily generate that amount.

The power from solar panels is DC, so would have to be converted to AC, to then go back to DC to power servers. (Lol.)

I think the coolest thing they could do is use the heat generated from servers to heat up their offices or nearby buildings.
Or they could accept that global warming is probably a load of bollocks, considering there's evidence of fraud and other shenanigans at some research institutes. Then they could not offset their carbon output and pass the savings on to us.

Like Andy said, I guess one solution to the energy storage issue would be to sell the excess energy to EDF (or whoever provides energy there) and then buy it back when it's needed. This way you eliminate the energy storage requirement, you still get a good deal (I take it that the difference between buy/sell of energy is minimal - especially if you generate more than you need on average) and you continue to do your bit to reduce carbon emissions. Not sure if the French energy providers buy power from individuals though...


Sorry I meant that solar is not efficient per se ( it has a low % of usability counting the amount of received sun).

Yep, thats good idea but I think that the electric generated would be sub-par of what they need and they would always need to get some from the grid. Of course that if they invest a big amount the will be quit independent from the grid unless they place a DC close to a river or similar.

You would probably end up having to go "grid tied" rather than running directly from a renewable source, as this would cut out the need for batteries (which cut your efficiency in half almost) and off-set the electricity bill. It also allows it to use power from the grid with no switching over should your renewable energy output drop below your usage, while still offsetting the power bill with what power is available from renewable sources. If you provide more than you use then the power grid will pay you instead
Having a combined electric (eco friedly) supply would be very f.. sweet . No provider has such IIRC, right?

Power grid paying I think has to do with countries policies

would 10 MW cut down your power requirements?

It is still in development, testing and in use on 1 server, but at the moment just charges a set of batteries. Which is not as efficient as we would like it, since the batteries do take up a bit of room.

what happened to no power project?
