We’ve worked hard to reduce the amount of energy our services use. In fact, to provide you with Google products for a month—not just search, but Google+, Gmail, YouTube and everything else we have to offer—our servers use less energy per user than a light left on for three hours. And, because we’ve been a carbon-neutral company since 2007, even that small amount of energy is offset completely, so the carbon footprint of your life on Google is zero.

We’ve learned a lot in the process of reducing our environmental impact, so we’ve added a new section called “The Big Picture” to our Google Green site with numbers on our annual energy use and carbon footprint.

We started the process of getting to zero by making sure our operations use as little energy as possible. For the last decade, energy use has been an obsession. We’ve designed and built some of the most efficient servers and data centers in the world—using half the electricity of a typical data center. Our newest facility in Hamina, Finland, opening this weekend, uses a unique seawater cooling system that requires very little electricity.

Whenever possible, we use renewable energy. We have a large solar panel installation at our Mountain View campus, and we’ve purchased the output of two wind farms to power our data centers. For the greenhouse gas emissions we can’t eliminate, we purchase high-quality carbon offsets.

But we’re not stopping there. By investing hundreds of millions of dollars in renewable energy projects and companies, we’re helping to create 1.7 GW of renewable power. That’s the same amount of energy used to power over 350,000 homes, and far more than what our operations consume.

Finally, our products can help people reduce their own carbon footprints. The study (PDF) we released yesterday on Gmail is just one example of how cloud-based services can be much more energy efficient than locally hosted services helping businesses cut their electricity bills.

Over the past few months, there have been a number of notable service quality incidents and security breaches of online services, including Sony’s PlayStation network, Amazon’s cloud service, Dropbox’s storage in the cloud, and countless others. The bar talk around “cloud” computing and online services would have you think that businesses and consumers are shying away from using hosted services, using Software as a Service (SaaS) applications, from storing their data “in the cloud,” or from migrating some or all of their computing infrastructure to virtual machines hosted by cloud service providers. However, there’s actually an uptick in the uptake of cloud computing in all of its various incarnations.

We (consumers and businesses) are using “cloud” services for all of the following kinds of activities:

1. Accessing and downloading media.

2. Accessing and downloading mobile apps.

3. Accessing and running business applications (CRM, hiring, ecommerce, logistics, provisioning, etc.).

4. Collaborating with colleagues, clients, and customers (project management, online communities, email, meeting scheduling).

5. Analyzing large amounts of data.

6. Storing large amounts of data (much of it unstructured, like video, images, text files, etc.).

7. Developing and testing new applications and online services.

8. Running distributed applications that need high performance around the globe. (All of the social media apps we use are essentially “cloud” applications—they run on virtual machines hosted in mostly 3rd-party data centers all over the world.)

9. Scaling our operations to handle seasonal and other peaking requirements—where we can take advantage of buying computing capabilities by the hour, rather than pre-paying for capacity we rarely need.

10. Back up and Disaster Recovery—keeping copies of our systems and data in remote locations, ready to run if a natural disaster impacts our normal operations.

In short, “cloud computing” in all of its instantiations—Software as a Service, Platform as a Service, Infrastructure as a Service, Cloud Storage, Cloud Computing, etc.—is here to stay. Taking advantage of the cloud (virtual computers running software in data centers distributed around the globe) is the most scalable and the most cost-effective way to provide computing resources and services to anyone who has reliable access to high bandwidth networking via the Internet.

What About Security and Back Up?
Most of us now realize that we’re responsible for the security and integrity of our information no matter where it sits on the planet. And we are better off if we have more than one copy of anything that’s really important.

SaaS and cloud providers have had a lot of experience helping IT organizations migrate some or all of their computing and/or storage to the cloud. And most of them report that most IT organizations’ data security practices leave quite a bit to be desired before they migrate to the cloud. Their customers’ data security and integrity typically improves dramatically as a result of re-thinking their requirements and implementing better policies and practices as they migrated some or all of their computing. (Just because data is in your own physical data center doesn’t mean it’s safe!)

It’s Time to Run Around in Front of the Cloud Parade
We’re now committed to living in the mobile Internet era. We treasure our mobility and our unfettered access to information, applications, media, and services. Cloud computing, in all its forms, is here to stay. Small businesses and innovative service providers have embraced cloud computing and services wholeheartedly and are already reaping the benefits of “pay as you consume” for software and computing and storage services. Medium-sized businesses are the next to embrace cloud computing, because they typically don’t have the inertia and overhead that comes with a huge centralized IT organization. Large enterprises’ IT organizations are the last to officially accept cloud computing as a safe and compliant alternative for corporate IT. Yet many departments in those same large enterprise organizations have been the early adopters of cloud computing for the development and testing of new software products and for the departmental (or even corporate) adoption of SaaS for many of their companies’ most critical applications.
