Why Green IT is not happening?

Since every business want profit, business works on profit, so you have to explain them profit of "GREEN IT". 

You will get the result.

There is no proper energy management both in terms of capacity and cost and this can only be effective through advanced monitoring, modelling and measuring techniques and processes which the concerned IT managers are not doing. Though managers talk about green all the time, but when it comes to implementation there is nothing happening from their side, and this non implementation of Green IT trend is mostly seen in datacenters where the IT managers are not paying attention for measuring, monitoring and modeling the energy use, and in many client conversations reveals that although the green IT and datacenter energy issue has been on the agenda, but then many managers feel that they have to deal with more immediate concerns before focusing attention on their supplier's products.

Nowadays, we all need to be able to do our business 24/7. That means that offices will have to be able to access the data around the clock as well. The majority of the energy-consumption is taken up by servers that need to be running day and night. Allowing several hours of downtime each day will make a lot of difference

I reckon "Green IT" was never much more than IT industry generated hype in the first place - just another marekting label aimed at getting people to buy new technology.  Now we've got "virtualisation" and "clouds" to keep us occupied, Green IT can go whence it came . . .

Sorry if you find this cynical but the IT industry is in a class of its own where gimmicky marketing is concerned.

Green IT only works if everone in the office is willing to participate in shutting down equipment when it is not needed. A lot of computers and monitors keep running just because it 'takes too long to shut down/start up'. Ensure that the participants are willing to shut down the machine and wait a few minutes for it to start up.

While Green-IT is always a good thing to mention during sales-pitches, there is always a matter of cost. Green IT doesn't have that much revenue (and it sometimes even costs money) in respect to the money that is made outside the company. Only the very large and the very small companies benefit from Green IT. Those in the middle have the least effect for themselfs, but would have the largest impact in total (because of sheer numbers)

People are preoccupied with day to day operations and people does not want to waste time in Green IT.

Business are still in the old ways of "profit concept" only now are the days for "profit with honor" deeply understanding social responsibility...unless this thing deeply understood Green IT will have it's way.

May be the managers are not aware of how much energy is getting consumed by their data - centers each day. Suppliers and clients should work together to find a solution that is green and cost efficient, which would be a value add for the organisation.

Some study (cant remember the article/link) reveals that less than 50 % of the managers insists on switching off the monitors/ work stations at night!,

More than 25% of those "committed green"s are not aware of their options available. All what they need are awareness and a little push, that can drive them ahead to a more greener environment at their disposal.

Make them understand that the green IT make their IT Green, along with their pocket. Rise in profit with reduced cost means greener face for your competition!
