Executive Summary (Part I)
• Things were bad in energy (for 3 decades)• Deng Xiaoping came to power
— A group of academics suggested a new approach to energy— Deng listened!
• Things were much better (for 2 decades)• The market became king
— Energy went off track again• There are solutions
— The Chinese government and Communist party areresponding, somewhat in the manner of Deng

Part I: China’s Energy History in Three Acts
“Soviet Style” Energy Policy (1949-1980)
Deng’s Initial Reforms (1981-1992)
Transition Period (1993 to 2001)
5
“Soviet Style” Energy Policy (1949-1979)
• Single objective was rapid energy supply growth• Energy prices greatly subsidized• Central allocation system provided energy primarily to heavy industry• No attention to environment• Result: one of the world’s least efficient (and fastest growing) energy systems

Deng’s Initial Reforms (1980-1992)
• Key meetings among more than 100academic energy experts in 1979and 1980 stated:— China energy policy in crisis— need for radical reform— major changes identified:
(1) energy price reform, and(2) serious attention to energy efficiency
• Government quickly implementedreforms in Sixth Five-Year Plan(1981-1985)

Energy-conservation policies & measuresin Phase II
• Energy Management—factory energy consumption
quotas—factory energy conservation
monitoring—efficient technology promotion—close inefficient facilities—controls on oil use
• Financial Incentives—low interest rates for efficiency
project loans—reduced taxes on efficient
product purchases—incentives to develop new
efficient products—monetary awards to efficient
enterprises
• R D & D– funded strategic technology
development– funded demonstration projects
• Information Services– national information network– national, local, and sectoral
efficiency technical servicecenters
• Education & Training– national, local, and sectoral
efficiency training centers– Energy Conservation Week– school curricula

Transition Period (1993 to 2001) and After
Rapid movement towards market-based system…—Dramatic energy price reforms (raised all energy prices to
consumers)—Enterprise reforms increased price sensitivity
…but past successes in improving energy efficiency werebased on mechanisms that were disappearing…
—Elimination of energy quotas—Low incentives for monitoring in industry—Difficulty in continuing energy efficiency loan subsidies—New tax code (1994) eliminated tax breaks for efficiency

Part II: Energy Crisis inChina: 2001 to present
repeat of much earlier “inglorioushistory”??
13
Executive Summary (Part II)
• China faces a serious new energy crisis— Most Chinese see the energy shortage as the crisis— The real crisis is in energy policy (just as in 1979)
• A key issue: how can investment be attracted to energyefficiency and how can government policy spur suchinvestment?
• A failure to rein in energy demand growth will have seriousimpacts— The environmental consequences of energy policy failure are truly
frightening— Rapid energy growth portends economic consequences of equal
concern
14
Current Energy Crisis
• Energy demand growing very, very fast• In 2004, widespread power shortage (24 of 31 provinces)• Soaring coal prices• Transportation bottlenecks for coal• Significant economic losses• “Surge” in oil imports especially as oil is used in place of coal
15
Since 2001, energy use has grown much fasterthan GDP, reversing patterns from 1980 to 2000

Growth in heavy industry has beenextraordinary in past five years:
industrial efficiency especially critical
• Consumes >60% of energy• Technical complexity: many different types of processes• Extraordinary growth in past five years• Existence of many old, legacy industrial facilities

Part III: The FutureWhat might happen? What is to be done
to end the crisis?
28
Executive Summary (Part III)
• Things could get worse— Very unlikely, but they could continue on the present path
for some time
• Things could get better— There is some chance!!
29
China’s National Energy Strategy
“Energy development and efficiency haveequal role (emphasis on efficiency)”
• But supply investment at RMB 424 billion ($ 50B)while energy conservation investment at RMB 23billion ($3B) in 2003 !!
30
Energy Investment
• Energy supply investment is ~18 times energy efficiency investment
• Energy efficiency investment needs to increase from $3B to $25B per year (avg over next decade)
_______________________________________________________________
China’s government now recognizes the urgency ofenergy efficiency
• The reform period (1980-2000) showed that energy efficiency wasessential to achieve economic goals (Deng Xiaoping)
• The current leadership recognizes the same imperative (Plenary of theCommunist Party, Nov, 2005)—Premier Wen Jiabao:
“Energy use per unit of GDP must be reducedby 20% from 2005 to 2010”
• Statement reiterated by the National Peoples Congress (March 2006)
• National Development and Reform Commission creating and re-creating aggressive energy efficiency policies and programs
32
The loss of control led to imposition of new 2010target of reducing energy/GDP intensity by 20%

Policies• Microeconomic policies (targeting energy efficiency)
— targets for energy efficiency for industries, with strong incentives(carrots) and penalties (sticks)
• Key supporting policies: information and technical guidance; strengthening localenergy conservation service provider network; and subsidies directly connectedto achieving industrial targets
— enhanced enforcement of tighter building energy standards,— tighten and assure compliance with appliance efficiency
standards,— strict enforcement and strengthening of auto fuel economy
standards,— initiation of demand-side management programs of scale in
several electric utilities, and— investment in mass transit alternatives.
36
Policies (cont)• Macroeconomic Policies
— Revisiting of energy prices to better reflect costs and taxes to betterachieve social/political objectives
— Re-creation of successful approach (during 1980s and part of 1990s)of subsidizing investments in energy efficiency
— Policies that result in additional closings of energy inefficientfactories
— We also recommend exploration of ways in which macroeconomicpolicies can lead to structural changes favoring lower energy use.
