MGI offers an in-depth look at what's driving soaring global demand for energy in different countries and end users (including commercial and residential buildings, road and air transportation, energy-intensive industries such as chemicals and aluminum, less-energy-intensive ones such as food processing, and electrical generation). Using a proprietary economic model, MGI provides a glimpse into how global energy will grow to 2020 with current policies and sizes the substantial opportunity to curb this growth and, with it, GHGs. It also includes a detailed discussion of the reasons why available opportunities to raise energy productivity are not being captured and what policies are needed to ensure they are.
