Marketing impacts
Acquiring a Green-E certification allows an organization to employ green marketing, which has become increasing popular as consumers are becoming even more environmental conscious. This gives them an edge in the market over other web hosting sites.
Efficiency on servers
Organizations participating in green web hosting tend use advanced cooling systems and allow air flow through the servers, which allows the servers to work at an optimum as the servers never over heat thus increasing efficiency.
Pros
The ability to provide a healthier and safer environment for the future generations as it is estimated that with the current emissions of the web hosting industry by 2020 the industry will be at par with the airline industry. Green web hosting provides an organization with the ability to tap into new niche i.e. green consumers. The improved efficiency is a great plus while lowered cost only sweetens the deal. Green hosting is the best deal that is saving many users by protecting our environment.
Cons
Green-e certification requires an organization to adhere to strict environmental regulations which can be costly to implement plus the purchase of one and carbon offsetting is cost also.
Limitations
Alternative energy sources and energy saving equipment can at times reduce on speed and efficiency.
