Bruce Worthington: Power Efficiency in Windows 8 and Beyond

Charles — Tue, 29 Jan 2013 21:28:25 GMT

In developing Windows 8, power efficiency was a primary engineering theme. This means that all aspects of the system were designed and developed with efficient power usage in mind. It's paid off—Windows 8 is the most power efficient version of Windows to date.

In this video, Windows Development Lead Bruce Worthington, an OS power and performance expert who leads a team of engineers working on Windows power management fundamentals, sits down with us to share the story of power efficiency in Windows 8. The renewed focus on power has paid off and is evident across the Windows ecosystem—from Windows on tablets, notebooks, hybrids, and desktops to Windows running in the data center.

Huge thanks to Bruce for this excellent conversation!

Tune in.

BUILD Expo: Intel on Windows Server 8

Son VoBa (SVoBa) — Tue, 27 Sep 2011 00:34:05 GMT

Aman Kansal: Inside Joulemeter

Charles — Tue, 14 Sep 2010 17:56:00 GMT

Joulemeter is a software-based Microsoft Research project designed to measure the energy usage of virtual machines (VMs), servers, desktops, laptops, and even individual software programs running on a computer.

Joulemeter estimates the energy usage of a VM, computer, or software by measuring the hardware resources (CPU, disk, memory, screen, etc.) being used and converting the resource usage to actual power usage based on automatically learned realistic power models.

Here, we talk to MSR research scientist Dr. Aman Kansal about what Joulemeter is and how it works.

Mark Aggar: Energy Smart Software

Charles — Tue, 14 Sep 2010 00:00:00 GMT

Ensuring that applications work well with Windows Power Management is a vital step in providing a solid end user experience and reducing IT energy costs. Developers need to ensure their applications are Energy Smart.

Here, we visit Mark Aggar, a Director in the Environmental Sustainability organization at Microsoft to get some insights into what energy efficient computing means and why it matters. Further, since Channel 9 is a comfortable place for developers, we discuss developing Windows applications that work in concert with Windows Power Management to effectively and efficiently use energy resources.

In some sense, energy efficient computing, like trustworthy computing and software security, is a journey that will continually evolve over time. The concept of energy smart software has only recently hit the general purpose computing mainstream. Of course, in the IT world, system administrators are always trying to maximize energy efficiency in large datacenters and have energy conscience for a some time. But what about developers?

NOTE: The Adobe Flash Player power management issue Mark mentioned during the conversation was fixed in version 10.1 and you should update.

Power Management features for energy efficiency in Windows 7

Adam Kinney — Tue, 16 Jun 2009 17:00:00 GMT

This is an interesting post from Microsoft's Environmental Sustainability blog on Power Management in Windows 7. Features smart things like scaling down hardware power needs when they're not in use. Your network card doesn't need full power when its not in use, right? More details are available in the post.

New Power Management Features : Windows Server 2008 R2

Phil Pennington — Thu, 21 May 2009 01:07:00 GMT

Windows Server 2008 R2 (i.e. "Windows 7 Server") introduces significant advancements in Server Power Management capabilities. You may never win a Nobel prize for building an application that plays well with Server Power Management policies nor by configuring a power-optimized data-center, but you'll gain lots of respect for returning real green cash savings for your customers. We think that makes lots of of sense for both Developers and IT Professionals.

Gain insight into new and future power management features and learn more about Windows system Power Management via additional resources listed at MSDN Code Gallery.

Verdiem: Using Software to Curb Energy Abuse

Charles — Tue, 26 Jun 2007 17:46:53 GMT

Global carbon regulation is arguably the largest risk and opportunity most corporations will face in the beginning of the 21st century. It has been estimated that turnover in the global carbon marketplace could exceed a trillion dollars in the next five to ten years. Voluntary and mandatory reporting protocols are emerging. How can an organization know its true carbon footprint and exposure? What options are available to manage corporate carbon risk? What impact can energy efficiency programs have on reducing a corporation’s carbon footprint?

Verdiem provides power management software for PC networks; their Surveyor software provides measurable energy and cost savings through network level control over pc and monitor power settings administered via windows services that to date translates to:

over US$32 million in customer ROI
over 324,500,000 in kwh saved
energy saved by Verdiem customers is equal to taking 34,00 cars off the road and reducing Greenhouse emissions by 277,555.44 tons

Verdiem really puts into perspective how we are all effecting the world around us, and how the global marketplace is shaping up to address these issues.

Here, we chat with Bruce Twito, Verdiem CTO and VP of Product Development about how Surveyor works, the impact Surveyor has on global carbon reduction, and we get unfiltered feedback for the Microsoft technologies that Verdiem relies upon for their core business offerings.
