What is the relationship between information technology and environment?

The relationship between information technology and the environment is sort of mixed.  In some ways, IT is good for the environment, but in other ways it is bad.

Bad: The main problem with IT is the fact that, as we get more and more IT, the demand for electricity rises (as more people want to use electronics in more ways).  This, of course, means more fossil fuels will be burned to make the electricity.  In addition, some compnents of electrical devices are very harmful to the environment if not properly disposed of.

Good: Ideally, IT can be used to help reduce stress on the environment.  A good example of this is the "smart grids" that are under development.  These would, it is hoped, help us use electricity much more efficiently, thus reducing the demand for electricity and the amount of resources used to produce that electricity.

I hope this is the sort of thing you meant by your question.
