Future superavits in Energythaca

On one hand, the rise of renewable energy, even before the 100% goal, will bring superavit of power. This means there will be excess power that is not required in the system. It already is happening and it will be even more so. This power can be stored, but of course, using it directly is more efficient and thus, preferable.

On the other hand, the penetration of robotics and software will change the jobs available for humans, as is in discussion in Davos these days. This means there will also be a superavit of productivity.

We will have Superavit of Power and Superavit of Productivity, that we must use wisely to Sigue leyendo


Google energy storage

I’m surprised Google Energy has still not got it…

How did they create the most competitive data centres in the world to grow so fast? How could they build the most competitive energy storage centres in the world?*

If you know the answer to the first one, you probably know what I mean in the case of energy storage.

The key was and is to use inexpensive harware. With servers, rapid obsolescence meant they wouldn’t need to repair the PCs used for their servers, many of the servers wouldn’t ever work, and the design had to be optimized to work around these failures. Of course now they are interested in the most energy efficient server systems, as that is the main cost for operating data centres, but the cheap and fast concept remains.

In the case of battery storage, Sigue leyendo
