Green from the roots up, Sustainable from the top down
Google.org is the not-for-profit arm of Internet search company Google.
After hearing about some of their initiatives, I was curious to learn more about Google.org. I contacted my friend Vint Cerf, Google Vice President and Chief Internet Evangelist and asked him if he’d come on the show to talk about Google.org and Google’s sustainability projects.
Vint very graciously agreed to and so we have this video. Thanks Vint.

If Demand Response is such a good idea and will help get more renewables onto the grid, why isn’t it being embraced by the grid management companies?
Most grid management companies have been in business for decades managing a grid in which the supply is manageable and the demand is variable but reasonably predictable – typically daily demand is “this day last year +2.5%”!
Now grid management companies are faced with a situation where an increasing percentage of their supply is coming from variable sources (i.e. wind) – if the wind blows more than anticipated, too much electricity is generated and if it blows less than anticipated, the converse is true. This totally messes up their planning and consequently grid management companies hate wind, and think of it as unpredictable, negative demand!
Instead of having such a negative attitude to renewables and shutting them down in favour of fossil fuels they should be asking how can we facilitate the greater penetration of clean renewable energy sources onto the grid.
In the coming years, the demand for electricity will increase significantly as transportation goes more electric (electric and plug-in electric cars, bikes, trucks, etc.) and as heating moves more to electricity. This will add demand to the grid system but this increased demand is eminently movable – for the most part you don’t care if your car re-charges at 7pm or 4am as long as it is re-charged when you want to leave for work at 8am. Similarly with heating, if you use storage heaters (and they will become more common) you don’t care when they suck in the heat as long as they heat the house the following day.
If you can move the demand to a time when traditionally the requirement for electricity was low, you can deliver it over the same infrastructure, thereby selling significantly more electricity without having to massively upgrade the network.
The upshot of this is that an increasing movable demand (the ability to time shift consumption) should be a strong business case for a real-time electricity market. Let demand be guided by supply (as indicated by price). With a real time market for electricity you need never shut down wind farms in favour of fossil fuels, you sell more electricity and you enable a greater penetration of renewables onto the grid. Win, win, win.
Why hasn’t this happened already? Ask your local grid management company.
