limiting energy consumption
With their increasing technical capacities, computers in use today consume more
and more energy. As a result is energy costs can represent up to 40% of a company’s
total IT budget (power supply to equipment, air conditioning for rooms with computers,
etc.). Another consequence: emerging energy supply problems for companies.
Companies can thus no longer afford not to adopt approaches for sustainable management
for energy resources. By offering companies adapted management tools, Green IT
can enable them not only to reduce costs, but also to secure their energy supplies.
In this context, relying on renewable energy sources and “positive energy” buildings
can be part of the solution.
Positive energy buildings produce more power than they consume (by using solar
panels, for example). "Companies should rely on renewable energy sources to bring
down the cost factor by at least 50%, and secure at least 50% of their power supply,”
Philippe Eon suggests.
prioritizing concentration, virtualization and paperless process
It is also essential to directly alter how information systems are organized.
Through access to remote servers grouped in “green data centers” managed by service
providers, companies can equip their employees with lighter PCs. The advantage
is that using computers with limited storage capacity consumes less power, and
their life expectancy is longer. “The financial and ecological savings measured
in terms of greenhouse gas emissions are immediate and considerable,” underscores
Philippe Eon.
Beyond concentrating servers, there are countless possibilities in terms of virtualization
and dematerialization. Video-conferencing can be used for meetings and interviews,
invoicing can be managed electronically, etc.
leave no stone unturned
Beyond actions aimed at minimizing the impact of ICT, and capitalizing on their
potential for environmental savings, Green IT initiatives can be accompanied by
complementary measures. They include:
- changing day-to-day behavior,
- creating products and solutions that save energy and reduce carbon dioxide emissions,
- designing recyclable products,
- encouraging the reuse of products,
- involving company partners and suppliers in the initiatives.
