One of the keys to improving anything is having enough information. This has been widely discussed in environmental circles, and recent innovations such as the Kill-A-Watt and the awesome hack the Tweet-A-Watt have lead to a more widespread appreciation for just *knowing* the amount of energy your appliances, computers, and home entertainment systems are consuming. In addition to being surprising, the reality is that all too often assumptions are made about where to focus effort to fix a particular problem – or worse, you don’t even know a problem exists. But what to do with this information? At home it’s as easy as putting your devices on a power bar – such as your home theater – and turning it off when you’re not using it. Having the data enables you to make a decision – the decision to save money because all of the sudden it’s tangible.
These kinds of details can be applied at a really big and small scales too. What if you could measure the amount of power went into making your car? The amount of energy each Google search takes? The amount of energy for every tweet? Would knowing a tweet kills a tuna make you think twice? Would it enable you to make better decisions about the products you consume? Would it allow your customers to make better decisions about their energy efficiency?
This can apply to the hosting world too. Computers currently use more energy than the entire airline industry, and that’s expected to double within the next 5 years. Data centers consume a whopping 2-3% of the power in the United States alone. Hosting companies charge flat rates for collocation, virtual servers, shared hosting, etc. Bundled into that are the charges for electricity, and the electricity required to power the cooling. Unless you’re really close to the physical infrastructure, there’s no way to measure how efficient the servers are, or how much power your server is consuming. If we could measure the amount of power a server uses then you could incorporate that into the pricing of the server, and display the information separately. As a hosting company you would be able to make better decisions about which hardware, software, etc to use. As a hosting customer, you would be able to choose locations that are more power efficient. A slew of other possibilities exist. Due to power deregulation and trading markets in many locations, what costs a dollar during the day might cost 10 cents in the middle of the night.
Data centers are built for peak capacity, but there should be an incentive for customers to adopt more energy efficient solutions. Being able to measure (in)efficiencies also means that making decisions about moving to a container might be easier to justify.
