When it comes to energy efficiency, it's not only about cutting costs. It's about making smarter moves towards limiting the environmental impact of your business.
HP makes it easier to do with innovative and practical solutions that help you reduce energy consumption and costs. Read on to learn how you can expand energy efficiency across your company, from PCs, workstations and displays to notebooks, servers and printers.
HP LaserJet printers and new HP Inkjet printers automatically reduce power consumption after a set period of inactivity. With HP Web Jetadmin, you can remotely schedule sleep/wake-up modes or automatically turn off devices on nights and weekends.
You can also set duplexing as a default via Web Jetadmin and HP Universal Print Driver to consume up to 25 percent less paper.
Most HP LaserJet products require no more than 1 watt of power in off mode. And, by using HP printers with Instant-On Technology (IOT), you can get up to 50 percent energy savings over traditional fusing technology. The savings enabled by IOT since 1993 is the equivalet of removing 1.1 million cars from the road for one year — more than 5.25 million tons of CO2.
For graphic arts, the HP Scitex printer and ink technology can deliver reduced energy consumption through UV-cured printing, versus dryers used in solvent-based printing.
Desktops |

In May, HP Power Manager will be available as a free option on select configurations of HP desktop PCs. With it, users can be personally invested in reducing energy by custom-tailoring their PC power settings and viewing the estimated savings in real-world ways — such as with a comparison with CO2 emissions of a typical mid-size car.
HP business desktops also feature the latest energy-efficient processors. Many come pre-loaded with Verdiem SURVEYOR remote power management software(1) for centralized control over networked PC power settings.
Optional 80 PLUS power supplies available with many desktops extend energy efficiency further. Additionally, some models of 7000 series PCs have a solid-state hard drive. With no moving parts, that helps reduce energy consumption and cooling costs.
Further, HP thin clients can be up to 80 percent more power efficient than traditional desktop PCs with similar capabilities.(2)
Notebooks |
|
Many HP commercial notebooks leverage solid state drives and processors that can reduce heat and increase battery life. In addition, the HP Illumi-Lite display in select notebooks uses highly efficient, mercury-free LED screens, which can increase battery life by up to 90 minutes.(3)
Ambient light sensors on certain models help reduce power consumption by dimming the panel in low ambient light conditions.
And HP Smart AC Adapters have a built-in sensor that alerts the notebook when its power rating has been reached, allowing it to make power adjustments.
Workstations |
|
HP workstations have preset sleep states and adjustable fan speeds and power-saving processors. All 2008 models feature standard 80 PLUS efficiency power supplies. Soft power buttons make power down simple to reduce energy during idle time. The high-end model features the thermal efficiencies of HP liquid cooling technology.
Dynamic Smart Cooling can reduce energy consumption related to cooling by as much as 40 percent. It integrates data-center-wide sensors, intelligent control and automated provisioning, allowing the computing infrastructure to interact with the facilities that support the data center to optimize cooling.
Thermal Zone Mapping uses HP exclusive thermal metrics to highlight key physical attributes of air fluidity and heat transfer in a data center. It delivers a three-dimensional model of exactly how much and where data center air conditioners are cooling, so you can manage air conditioning for optimal cooling and energy efficiency.
A new HP ProLiant BladeSystem is 64 percent more power-efficient(4) than any other blade on the market. In fact, HP BladeSystem Thermal Logic technology can significantly reduce power, cooling and space costs.
If you're thinking about buying new technology, you can give your purchase the green light — with energy-efficient HP solutions from the desktop to the data center.

Savings based on a deployment of 1,000 thin clients, plus additional savings in air conditioning costs. Actual savings a customer could see will vary and is dependent on many factors, including but not limited to thin client usage patterns, electricity rates, desktops being replaced and manufacturing variability. |

Compared to standard cold cathode fluorescent tube (CCFL) display technology. Results achieved by comparing two similarly configured notebook PCs running on nine-cell batteries. Results are for the 2510p model and may vary for three- and six-cell batteries and for different applications, features and power-management settings. |
