With the Carbon Reduction Commitment (now CRC Energy Efficiency Scheme) turned into a flat tax and delayed by a year, many are questioning whether carbon regulation is real.  Last year, Mike Manos described a doomsday "CO2K" scenario similar to Y2K.  Now that some time has passed, governments have changed, and we've interviewed data center operations about the impact of carbon regulation, I'm weighing in on the issue.  Let's put it this way -- unless carbon tax is about FIVE TIMES the cost of electricity, there's no financial motivation to change behavior.  That means CO2K is more likely to be like Y2K -- essentially a lot of hype but ultimately a bust.
