As a conference hall or business center isn't being used,it means that the only power that is used is the power used by the participants' personal computers.Similarly conference organizers don't have to arrange for food or overnight accommodation (住宿) for participants of their conferences. All this means that less energy is used.
Often in business some companies actively choose to do business with other companies that do many things to reduce their negative impact on the environment.And Web conferencing helps you show other businesses that you are willing to work hard for the green cause.
So Web conferencing is much cheaper and greener and more people are willing to host and attend a Web conference.
