One of President Obama’s first actions has been to announce his intentions to build a ‘smart grid’ for the US energy infrastructure. WorldChanging explains the concepts behind the buzzphrase, and I’ll paraphrase their five broad categories here:
- End-user smart metering to use energy more efficiently
- Systems to integrate electricity generation with electricity storage
- A communications network that shares data on performance, demand and availability of power
- An ‘application platform’ that allows third-party utilities to connect the above systems together in useful ways
- Monitoring and controlling systems that allow the grid to respond to service interruptions in a self-healing manner
In other words, it’s a lot like an internet for power, if you will – not to mention a far cry from the crude lacework of cables and substations we have at the present time. There’s a lot of work to be done, but the benefits of investing the time and money promise to be immense. I wonder what our lot in Whitehall are doing about the UK grid at the moment?
