According to the report titled “How Dirty is Your Data?” Apple is still largely dependent on thermal power for most of its server sites. With US being a leader in the nuclear power field over 50% dependence on coal based power has been termed unfortunate by the report.
If that wasn’t all, the new facility too would be powered largely by coal. The report pegs Apple’s current dependency on coal based power at 54-percent while the same for Facebook and IBM has been pegged at 53 percent and 52 percent respectively.
It is not a legal requirement in the US to disclose the power usage by large corporations – at the same time, companies are wary of making their energy consumption reports public either. There is no data on the energy consumption required to power services like Gmail which are essentially in the cloud.
It is estimated that as the demand for services like these grow, electricity consumption by Data Centers which is currently pegged at 1.5 to 2 percent of world electricity consumption, will grow to four times in the next decade. In the US, 3% of all the electricity produced is already being consumed by data centers.
