Cloud computing leads to more efficiently run computers, so it must be green, right? But, how many companies are promoting their energy utilization information?  It seems most organizations are dragging their feet when it comes to publishing energy consumption details.  This leads some to believe the cloud is in fact highly inefficient and not at all green.
Other research suggests the cloud will continue to become greener.  Data centers today account from about 2% of all energy consumption, and that percentage is growing.  According to Pike Research, because of the migration to large aggregated cloud data centers, it is estimated that by 2020, data center energy consumption will drop by 31% from the energy consumption levels of 2010, resulting in a savings of $16 billion in energy costs.  This report also forecasts greenhouse gas (GHG) emissions from data centers should drop by 28% over the next 10 years.
What do you think, is the cloud actually green, or is this just Hype?
