Power Usage Effectiveness (PUE) is a metric measure created by the Green Grid to determine the energy efficiency of a datacenter.

PUE是由绿色网格组织推出的一个测量数据中心能源使用效率的指标。

A new law on green energy gives few clues as to how new producers can sell power to the grid, or whether the incumbents have to buy it.

新出台的绿色能源法案几乎未说明，新发电商通过何种渠道向电网出售电力，也未说明现在的电力供应企业是否要购买新能源电力。

A smarter grid will not only help people save energy or use it more efficiently, but will also promote the adoption of all kinds of green technologies, including wind, solar and plug-in vehicles.

更为智能的电网不仅能帮助人们节省能源或更有效地利用能源，还能推动使用各种绿色能源，包括风能、太阳能、电动车。

It is similar to the PUE rating (Power Use Effectiveness) developed by The Green Grid a few years ago, but it arguably is more targeted toward measuring power consumption and actual operations.
