Abstract
As the credit crunch, and rising costs, squeeze the wallets of almost every
business, the need to cut costs and improve efficiency is more important now
than at any point in the last few decades. Together with uncertainty around
the impact of human activities on the climate, these pressures are driving a
move towards ‘green' or ‘energy-efficient' computing. Best
Practice in Green IT: Implementing Green IT in the enterprise and its cost
benefits is a new report published by Business Insights that examines the
impact that business and IT is having on the environment, and why this is
becoming a board-level issue. It also provides a guide to how organisations
can cut their energy consumption, and therefore carbon footprint and annual
energy costs, throughout the organisation and over the lifecycle of IT
equipment, from the desktop and office consumables to the data center and the
recycling of electronic equipment. Understand how legislative responsibilities
of organisations regarding the environment and e-waste, provides a
comprehensive guide to the growing trend of ‘Green IT' with this new
report.
