Google & Siemens Show What's Possible in Green Energy
The IntegralBlade design has no glue joints in the turbine blade. The commercial version of this rotor will have a diameter of around 154m and a total sweep area of 18,600 square meters. (Source: Siemens)
Due to the lackluster way green energy is stored, I think the real innovation is how energy is stored in the system. The difficult part is storing the energy after creation. Demand and generation will never match up perfectly with green power. Renewable energy certificates, Green Tags, are the only way to trade in green energy. The non-tangible ticket is traded on the market. It might be required to buy them in some industries.
But I question the connection to actual energy produced. Where is it stored on the grid? Regulation areas? Ones that act just like a buffer to the grid. They do not have infinite storage. So, I am going to assume that the energy is lost somewhere in the power chain. This will require more research on my part.
Cabe, data centers use a lot of technology to lower their energy costs. Combined Heat and Power (CHP) where the heat from electricity genration is used for cooling can have a great impact. Generally some 40% of eclectricity costs in a data center go to heat rejection. There is a lot that data center operators can do to lower their elecrticity cost. All those savings go right to the bottom line.
This is one of my pet issues and I'm so happy to see the big guys finally getting it and throwing serious support behind alternative energy. Also Apple is investing in wind turbine technology, too. Hope it's just the beginning!
