Overview
Challenges for sustainable energy in developing and industrialized countries
What is possible? - What is needed?Target oriented scenarios and policies („Back Casting)
The green pillars for sustainable energy: Efficiency + Renewables + Co-/Trigeneration
A sustainable world energy strategy: efficiency inrease by 2% p.a. plus diversifying,greening and decentralizing supply
German case study: 80 % CO2 reduction (2050) plus nuclear phase out is affordable
Energy efficiency needs highest priority to buy down the costs of renewables
Fostering eco-efficiency: a new paradigm for technological progress

Sustainable Energy Systems: Challenges for IC and DC
Industrialized Countries (IC)
Absolut decoupling of primary energy consumption and wealth (GDP growth)Only moderate growth of energy services „New models of wealth“: Eco-efficiency, service orientation, sustainable life styles, „qualitative“ growth
Developing Countries (DC)
Relative decoupling: Lower the annual growth rates of energy consumption (energy costs), increase living standards, accelerate qualittative GDP growthMore energy services with less energy through increasing efficiency ("leap frogging)
Comparable Challenge:
Sustainable energy systems based on „three green pilars“: RUE, REN and CHP„Greening“ energy supply, decentralisation, liberalisation, democratisation!

Projected Impacts of the Kyoto Protocolon Emissions of Greenhouse Gases from Annex I Parties
Note: The estimateof emissions without the Protocol is based on five projectionsfrom internationalorganisations.Emissions in 1995have declinedrelative to 1990because of changesin economic growth in countries with economies intransition.

Recommendations of the German Environmental Advisory Council on Climate Protection Goals
•Global temperature increase: only 2o C should be allowed
•Rate of temperature increase: not higher than 0.2o C / 10 Years
•Increase of C02 concentration: below 450ppm
•World energy related C02-emissions: reduced by 45-60% up to 2050
•Industrialized countries should take the lead and reduce their C02-emissions by 20% (2020) up to 80% (2050)
•GHG per capita emissions: IC should reduce by 2/3 - 3/4; DC should limit the increase so that per capita emissions converge in 2050

Costs of Sustainable Energy Systems: Results of the German Enquete-Commission (without external costs)
“The share of system costs within a reference scenario will be 12,5% of GDP (2010) and can be reduced to 9,2% (2050)”
“Within a sustainable energy scenario (phase out of nuclear; 80% CO2-reduction) the share of system costs to GDP in 2050 will increase to 9,4-10,4%”
Within all calculated energy paths “the range of additional costs is relatively low and don’t differ much; therefore the calculation of the additional costs are relatively robust”
Recognizing the benefits from these additional costseven the highest additional costs “are socially acceptable - especially when external costs are taken into account”

Lessons learned from German Enquete-Scenarios
80% C02 reduction up to 2050 is technically feasible with different technological options on the supply side
But: 60-75% of C02-reductions must be realized by energy efficiency
Risk minimisation ( climate protection plus nuclear phase out) can be financed with moderate incremental costs
Greatest challenges for implementation:
decentralisation of the power sector - highly concentrated supply sidestrategic policies for energy efficiency increase in all sectorsconsensus building on sector and target group specific policy mixes

Targets for German nuclear phase out
• Based on a contract between government/producers
• 19 nuclear power plants are to be phased out
• Nuclear electricity generation (164,8 TWh/a):
• substituted by efficiency/climate friendly new capacities
• Limitation of the further nuclear electricity generation
to 2.623 TWh (from 01. 01.2000)
• Normally a nuclear power plant will be phased out after 32 years of operation
• Opportunity to change generation budgets from one plant to an other
• Prohibition for reprocessing of nuclear waste
• Use of intermediate stores while decisions on how to come to a final disposal are on the way
• The last nuclear power plant will be phased out between 2020 and 2025

A strategic energy efficiency initiative is needed!
Complete the liberalized markets (“level playing field”) on the demand side
Let efficiency compete with energy supply to deliver least cost energy services (“low bills” instead of only “cheap kilowatthours”; life cycle cost analysis)
Create a competition neutral incentive scheme for utilities and new actors to invest in cost effective energy efficiency technologies (“NEGAWatts”)
Combine national/ regional energy efficiency funds with e.g. DSM-schemes, procurement, rebates, standards, labelling, contracting/’TPF

A breakthrough for efficiency policies: the new EU-directive on energy efficiency and energy services (10/12/2003)
Potential for cost effective savings: 15-35%; correspond to over 200 million tons of oil/aAverage cost of saving electricity: 2.6 Euros/kWh compared to 3.9 Euros/kWh for delivered electricityEmerging markets for energy efficiency and energy services: to be worth 5 to 10 bn Euros per yearRemoval of current obstacle (e.g. lack of information/financing; institutional and legal barriers) with low transaction costs
Compulsory energy efficiency targets:a) Member States should save each year 1% more (compared with average of

Energy Efficiency - a „win-win-win“ - option
Increasing energy-efficiency contributes to several societal goals:
Competitiveness of the economy
Security of supply of energy services
Decrease import interdependencies
Protection of the environment
Positive employment effects
Increased welfare (lower energy bills)
Reduced geostrategic risks („war on oil“)

Reduce market barriers and market failures!
Split markets• no functioning competition between energy efficiency and energy supply• competition for “cheap and risky” power instead for least cost energy services; Asymmetrical market power• ´David-Goliath´-constellations: no fair “level playing field”• grids as “natural monopolies” Different requirements for return on investment (’pay back gap’)• Electricity suppliers: 15 years, industry: 2 – 3 years, households: 1 year• Separation of running costs and investments in public budgetsElectricity generation asymmetry• newcomer’s full costs vs. short run marginal costs of electricity suppliers• dumping prices of great utilities against newcomersInvestor/user dilemma/split incentives• rented building sector

Policy instruments for saving electricity
Federal energy efficiency funds:
• Invite tenders for energy saving projects or DSM programmes (e.g. rebate programmes, free give-away, direct installation programmes, conversion of electrical heating to gas or district heating)
• Evaluation of the programmes• Financing according to the Danish or English example; e.g. by ‘Public Benefit Charge’ (additional charge on electricity network prices) or eco-taxes
Public procurement
Federal energy agency/ ESCO/ Professional training programmes(e.g. Swiss RAVEL)

Lessons from experiences in European countries
There are highly efficient energy efficiency programmes by energy companies and other actors in the liberalised EU-energy market
A supportive framework is needed to achieve a broad implementation of energy efficiency
Mechanisms in conformity with the market and with a funding neutral to competition are established in UK, Denmark, NL and 20 states in the US
Possible result of energy efficiency programmes and services in the EU
=> 10% electricity and gas savings within 10 years possible; net economic gain: around 10 billion # per yearThe new “EU-Directive on energy efficiency and energy services” (10/12/2003) is a big step forward

Independent dedicated funds
Financed from levy neutral to competition (e.g. 0,15 c#/kWh electricity; 0,05 bis 0,15 c#/kWh gas for the domestic and the small commercial sector; similar percentages for other customer groups) or from part of the ecotax-> leads to lower energy bills!
Tender for innovative energy efficiency activities+ application scheme for energy companies (e.g., 50% of the funds)

E-Parliament -Initiative: Limit Standby Power to 1 Watt! Policy options and best practice for 25.000 parliamentarians
“Did you know that standby mode is consuming a growing share of the electricity generated in your country – often as much as 5% already?”
Facts:
• Producing electricity for machines to do nothing is costing billions of dollars and is emitting hundreds of millions of tons of carbon dioxide
• A standard of 1 Watt would save 300TWh p. a. in OECD households up to 2030 and 300TWh/a in all sectors up to 2020
• Some governments are already taking action:a) US: by requiring a 1 Watt maximum stand by power for many
appliancesb) Australia: active process of voluntary measuresc) Denmark: combining public education with labelling
