Microsoft, Apple, Google Power Data Centers with Renewable Energy
It takes a lot of energy to enable web users to stream videos, downloads books and other online activities—about the same amount it would take to power 30 nuclear power plants.
Data centers around the world use about 30 gigawatts, or 30 billion watts of electricity, according to Green House Data. U.S. data centers account for nearly one-third of that amount, according to estimates compiled by The New York Times.
Stanford University research fellow Jonathan G. Koomey told the publication that U.S. data centers used about 76 billion kilowatt-hours in 2010, which equates to about 2 percent of the electricity used by the entire country that year.
Powering data centers with renewable energy sources like wind or solar is an obvious solution to global energy problems. Here are three companies who have announced plans to power their data centers with renewable energy:
The software corporation announced Monday that it would buy 110 megawatts (MW) of energy from a wind farm 70 miles northwest of Fort Worth, Texas to power its San Antonio data center. The 20-year agreement marks the first time the company will power a data center with clean energy.
"For Microsoft, signing a long-term [power purchase agreement] for wind energy is a significant milestone in our commitment to carbon neutrality," Robert Bernard wrote on the company's Green Blog. "It also underscores how the carbon fee is changing the way Microsoft does business globally. By placing a dollar value on a metric ton of carbon, Microsoft is building environmental sustainability into our long term business planning and creating a blueprint for more purchases of renewable energy like this one."
- An increase in the percentage of renewable energy, from 35 percent to 75 percent, over the last three years at corporate facilities.
- Apple opted out of default grid mix program in Prineville, OR in order to power its under-construction data center with wind, hydroelectric and solar.
- Like existing data centers in Maiden, NC and Newark, CA, a new Reno, NV site will be completely powered by renewable energy
Google purchased 48 MW of wind energy in 2012 to power a data center in Oklahoma that helps store Gmail, Google Docs and search engine results, Greenpeace reported. The company was faced with using a 50-percent coal mix before striking a power purchase agreement with the local utility.
Google also has a habit of investing millions in renewable facilities. The company Google announced its 13th renewable energy investment in three years last month by helping to fund a 265.7 MW solar project in California. The company pledged $103 million to Silver Ridge Power’s Mount Signal Solar project, which will power 80,000 homes and create 900 construction jobs. Google's clean energy investment portfolio—which has eclipsed $1 billion—also includes projects in Germany and South Africa.
“We invest in these projects because they make business sense, because they help put more renewable energy on the grid and because they have a positive impact on the local economies where they operate,” Google corporate finance head Kojo Ako-Asare said.

For centuries, the delicate silver dove has been a symbol of love and fidelity.
Biodiversity and Habitat Loss<p>Their near extinction is a symbol of the <a href="https://www.dw.com/en/global-biodiversity-outlook-targets-extinction-summit-new-york-pledge/a-54932895" target="_blank">biodiversity crisis</a> in the UK, largely driven by habitat destruction. Britain is now one of the countries with the most <a href="https://www.wwf.org.uk/future-of-UK-nature#:~:text=The%20UK%20is%20one%20of,than%20half%20are%20in%20decline" target="_blank">depleted nature</a> in the world according to the World Wildlife Fund. Half its plant and animal species are in decline and more than <a href="https://www.rspb.org.uk/about-the-rspb/about-us/media-centre/press-releases/let-nature-sing-wales/#:~:text=a%20natural%20tragedy.-,Over%2040%20million%20birds%20have%20vanished%20from%20UK%20skies%20in,unaware%20of%20the%20impending%20danger" target="_blank">40 million birds</a> have vanished in just half a century.</p><p>"[Turtle doves] are the canary in the [coal] mine because there are all these other species before it and after it," said Tree. "It's an umbrella for all the other species that are heading that way."</p><p>Turtle doves migrate south through Europe to sub-Saharan Africa between July and September, ending up in dry woodland and farmland areas of countries like Mali and Senegal for winter. </p><p>Droughts in West Africa and the Sahel region are believed to have contributed to the fall in turtle dove species recorded in northern Europe, with low rainfall reducing supplies of the seeds and insects the birds rely on for energy for the long journey home.</p>
Conservation and Farming<p><a href="https://www.operationturtledove.org/" target="_blank" rel="noopener noreferrer">Operation Turtle Dove,</a> a partnership project of charities including the Essex Wildlife trust, works with landowners and farmers to actively build turtle dove habitat.</p><p>Outten works with <a href="https://www.ebws.org.uk/birdsites/blue-house-farm-ewt-north-fambridge" target="_blank">Blue House Farm</a>, a 660-acre nature reserve in the UK county of Essex, where they have replicated weedy fallow plots. </p><p>"We work on it every year to make sure it's in the condition it needs to be with plants such as clovers and black medic," Outten said. "These plants are native to the landscape and produce the seed the birds feed on." </p><p>The birds eat a wide range of seeds from various plants that would have been abundant 50 or 100 years ago, added Guy Anderson, program manager for species recovery with The Royal Society for the Protection of Birds (RSPB). </p><p>"But it's simply true that with the gradual process of <a href="https://www.dw.com/en/farming-without-pesticides-how-can-we-make-agriculture-greener/a-52216796" target="_blank" rel="noopener noreferrer">intensifying our agricultural production</a>, the availability of those seeds has dropped and dropped," said Anderson.</p><p>Part of the project includes supplementary feeding — providing sources of food in the form of seed or grain. Under the Countryside Stewardship Scheme in England, farmers can receive financial support to create a turtle dove habitat. </p><p>Though they haven't recorded an increase in doves across the sites in the four years of working on the project, Outten said they are seeing improvements in how landowners and farmers manage habitat for the birds. </p>
A Turtle Dove Haven<p>The 3,500-acre Knepp Estate in West Sussex is another project taking a different approach and one of the few places where turtle dove numbers are increasing.</p><p>Isabella Tree and her husband Charlie Burrell converted their intensively farmed land into a rewilding project almost 20 years ago. They have let the land return to nature.</p><p>Just one year after they'd finished <a href="https://www.dw.com/en/uks-most-talented-architects-are-not-human/a-35952128" target="_blank">rewilding</a> the southern part of their property, they heard turtle doves for the first time. It's now a breeding hotspot for the birds with an estimated 19 pairs. Knepp is also home to <a href="https://www.rewildingbritain.org.uk/rewilding/rewilding-projects/knepp-estate" target="_blank" rel="noopener noreferrer">2% of the UK's population</a> of nightingales. </p><p>Tree is critical of supplementary feeding schemes that, in her view, are short term. She questions the chances of turtle doves getting to feed on scattered seeds before other mammals eat them first.</p>
