Why We’re Sticking with Renewable Energy Credits (for Now)

Written by Joe Kozlowicz on Tuesday, December 30th 2014 — Categories: Green Data Center

Bloomberg Businessweek posted an article this month about the seeming decline in popularity for Renewable Energy Credits (RECs) among large companies in the United States. Citing Walmart, Safeway, Hilton, and others, the piece claims RECs have little power to spur new renewable development and don’t really eliminate the carbon emissions that companies claim.

We’ve covered the What and Why of RECs here on the blog before. Basically, each REC stands as a record of one megawatt-hour of renewable energy added to the general pool traveling the electric grid. When a company or individual buys an REC, they claim credit for that green energy. The income stream from REC purchases travels through brokers and on to renewable energy development companies, who use the extra funds for new projects like wind farms or solar arrays.

Where RECs get tricky is when companies use them as part of their claims to be carbon-neutral, or as strictly a marketing trick. The Bloomberg piece makes this clear when it reports a Hilton VP as stating RECs weren’t “having a major marketing impact.”

Big data is the practice of locating patterns in enormous datasets to make better decisions. It enables intelligent decision-making across industries and applications.

Scalable cloud environments are great for big data platforms, but they come with their own set of planning and management concerns. In many big data environments, a hybrid solution may be the best fit. Let’s see what IT managers have to contend with to deliver the big data insights demanded by CIOs and CEOs.

Your Colocation Location Can Make All the Difference

There are plenty of factors when sizing up colocation providers: available space, power configurations, efficiency, support services, networking, etc. But one aspect makes all the difference, with ripple effects on many of these other factors: location. Depending on your infrastructure demands, you might need a data center nearby for low latencies or far away for disaster recovery; in either case, the location can also impact power pricing, energy efficiency, and connectivity.
