The broad acceptance of Power Usage Effectiveness (PUE) as a measure for data center energy efficiency is to be welcomed. After all, if we don’t measure it, we won’t improve it. However, the limits of PUE are widely recognized. Amongst the most glaring anomalies is the fact that improving the efficiency of your IT equipment, without

Most would agree that smart grid is the most happening sector in the clean tech industry right now. It is trying to revamp our outdated and inefficient electrical grids through digital technology. The goal is a green grid which will bring us power savings and lower carbon dioxide emissions.

Of late we have seen many companies trying to take on the energy management challenge from the user’s end. Home energy management products that control appliances at consumers’ homes to save energy, reduce cost and increase reliability and transparency is an integral part of smart-grid strategy.
