Global Electrification: Trends and Challenges David G. Victor Program on Energy & Sustainable Development Stanford University presented at: Chinese Academy of Social Sciences 18 March 2005
What is Electrification? At least three definitions: 1.Access to Power 2.Use of Power 3.Pervasiveness of Electricity in the Economy I will focus on #1 and #2.
PESD studies on “Energy Transitions” China: CASS Partnership –What explains China’s success with rural electrification? South Africa: ERC Partnership –MARKAL/TIMES; market failure analysis; new modeling tools; data assimilation India: several partnerships –Energy and Agriculture: general equilibrium modeling –Assessing electrification policies and patterns: peri-urban and rural –For profit distributed generation (India & Mexico) –Advanced metering and rural grid control
This talk: three points Broad Patterns in Electrification –Global, Regional, National & Household Evidence on the Causes and Consequences of Electrification Industrial Organization & Electricity Policy
1. Broad Patterns in Electrification
Global Access to Electricity: 1970 to 2030 People with Access to Electricity People w/o Access to Electricity 2000 – Total population 6B Source: World Energy Outlook 2002, IEA 1.6B/27% 1.4B /17% 2030 – Total population 8.2B 1970 – Total population 3.7B 1.9B /51%

Some Additional Issues: Measurement & Theory Measurement: –(eg.) Village vs. Household electrification in India: »85 % villages electrified »37% households electrified Theory: –(e.g.) Is theft an electrification strategy?
