At yesterday’s Investor Summit on Climate Risk, McKinsey’s economic research arm, the McKinsey Global Institute, released the report The Case for Investing in Energy Productivity (lead authors Jaana Remes and Diana Farrell).

The report finds that global investments on the order of $170 billion annually through 2020 ($38 billion in the US) in energy efficiency (what they call “energy productivity”) would deliver annual returns at a rate of 17 percent. Furthermore, these investments would reduce energy demand at half the cost of building out infrastructure to meet that demand. (For a sense of scale, $170 billion is 1.6 percent of global fixed-capital investment today.)

MGI finds some key energy-market failures that block the needed capital outlays:

Fuel subsidies that directly discourage productive energy use; a lack of information available to consumers about the kind of energy productivity choices that are available to them; and agency issues in high-turnover commercial businesses.

The report’s top-line recommendations for repairing these failures:

• Set energy efficiency standards for appliances and equipment
• Finance energy efficiency upgrades in new buildings and remodels (see Architecture 2030)
• Raise corporate standards for energy efficiency
• Invest in energy intermediaries (such as energy service companies aka ESCOs)
