The United States has the potential to save more than $1.2 trillion in energy costs and cut consumption by 23 percent by 2020, according to a report released last week by global management consulting firm McKinsey & Co. The comprehensive energy-efficiency strategy cited in the report removes approximately 1.1 billion tons of greenhouse gas emissions annually — the equivalent of taking the entire U.S. fleet of light trucks and passenger vehicles off the roads. It also could produce savings that exceed California’s total annual energy consumption.
This is an article devoted to the idea that a revolution in software design is needed in order to produce software –or as insiders often refer to it: the code – that is both greener itself and that is designed to help other systems and products become greener… i.e. more energy and resource efficient, less wasteful, more adaptive to current conditions.
There are two often intertwined paths to follow, both of which are important for this discussion. Code itself needs to become greener; using virtual resources more efficiently and thus using fewer hardware resources and less power to accomplish the same computing tasks. Code should also be designed with a feature set that enables other products, running the code, to use less energy and to be able to time shift their energy requirements to off peak periods.
