In a recent blog post David Jacobowitz, Google's Program Manager, Green Engineering and Operations, says cloud-hosted gmail is many times more energy efficient than privately hosted corporate email systems. He says:
"We compared Gmail to the traditional enterprise email solutions it’s replaced for more than 4 million businesses. The results were clear: switching to Gmail can be almost 80 times more energy efficient than running in-house email."

Sustainability, environmental issues and "green" have long since moved from "nice to have" parts of Corporate Social Responsibility, often part of the Corporate Communications (PR) portfolio, toward the center of management of the firm. A sign of this is the increasing involvement of the Chief Financial Officer (CFO) in sustainability issues. Most sustainability and environmental data is like financial data. It is financial data in many cases. (See this previous post for a discussion of the type [..]

Companies have many kinds of data that they have to manage, and from which they try to learn how to run their businesses better. "Green" or "sustainability" data is a relatively new category, at least compared to financial data which companies have been dealing with for centuries.
Here are some of the current and future sources of the data filling the Green Data firehose. Companies are at early stages of figuring out how to manage and benefit from many of these data streams. Essentially every c [..]

The always-excellent Economist blogger Babbage posts
about Facebook's new Prineville, Oregon, datacenter. Why did Facebook
opt for a location where most of its electricity will be generated by
coal? Google, for example, built on the Columbia River and has access to
cheap, renewable hydropower.

The answer, apparently, is that Facebook prefers the desert environment of Prineville because it allows ambient outside air to do most of the cooling without the need for energy- [..]

Datacenters world wide use 1.1-1.5% of all electricity, according to a new study. In the U.S. the figure is 1.7-2.2%. Over the period 2005-2010 global electricity use by datacenters grew by around 56%, and in the U.S. by about 36%. Both global and U.S. electricity use by datacenters had doubled between 2000 and 2005, so this is a significantly slower growth rate over the more recent period.

This weekend's disruptive construction event on the I-405 freeway through the Sepulveda Pass in Los Angeles will, theoretically, increase the capacity of this vital artery. More cars will use it to take advantage of that increased capacity until it is as crowded and choked as it was before.
