  1. Priorities for renewable energies and energy efficiency technologies by 2020 Clemens SchneiderResearch Fellow Research Group Future Energy and Mobility Structures ETUI conference “Climate Change:An opportunity for social cooperation“ 29-30 March 2011Hotel Crowne Plaza, Brussels

  2. Contents • 2020: mid-term landmark on the way to a low carbon society • Why dealing with technologies? • Criterions to identify relevant technologies • Technologies of energy supply • Energy efficiency technologies • Buildings • Electricity consumption • Transport • Technologies and cooperation: local action and acceptance • Example “Innovation City Ruhr“: a social laboratory Clemens Schneider

  3. 2020:mid-term landmark on the way to a low carbon society • Aims for a 2020 economy: • binding targets for all sectors (radical CO2 cuts)(energy supply, industry, commerce, households, transport) • a more flexible energy supply relying on decentralized structures (on the way to CO2 neutrality) • usage of BAT (= best available technologies) concerning energy efficiency • taking the whole carbon footprint of products into account (“life cycle emissions“) Clemens Schneider

  4. Economic instruments in Climate Policy and “technology neutrality”. So why dealing with technologies? • Economic instruments in Climate Policy and “technology neutrality” • Economic instruments are supposed to be “technology neutral”. • Neo-classical economic theory supposes that most carbon efficient technologies will be used. • BUT there are some limitations: • Deficits in cooperation (large and small groups) • Information barriers • External costs and benefits • Natural monopolies •  Markets neglect important options:centralized structures prevail. Clemens Schneider

  5. Using revenues from ETS and green taxation to foster “decentral” technologies • Criterions to identify relevant technologies: • Risks in research and development • Security of supply and price risks • Lead times • Market potentials • Dependance on infrastructures • Cost efficiency • Path dependance • Potential to save energy • Climate protection potential • Value added and employment • Acceptance • Source: Fraunhofer ISI (2010), modified Clemens Schneider

  6. CO2-Abatement potentials and costs Source: IPCC (2007) Clemens Schneider

  7. Low carbon energy supply technologies • Central structures: • Offshore Wind (Atlantic & North Sea) • Water power (Norway) • Concentrated solar power (CSP) • [Coal power plants with Carbon Capture & Storage (CCS)]  “Electricity highways“ needed: High Voltage Direct Current (HVCD) to connect Europe‘s • Decentralized structures • Photovoltaics • Onshore Wind • Local heat: Combined heat and power (natural gas or biomass fired)  “Smart grids” needed: intelligent demand and supply management to come to grips with volatile feed-in of renewable power Clemens Schneider

  8. Energy supply - the vision 2020:decentralized and flexible on the way to climate neutrality • Combination of central and decentral elements Clemens Schneider

  9. Energy efficiency technologies: demand side potentials Source: Wuppertal Institute (2006) Clemens Schneider

  10. Energy efficiency technologies: buildings • Initial situation • Many actors involved • Low rates of refurbishment (1% in Germany) • In spite of rising energy prices and public co-financing shares of high efficient refurbishment remains low •  Cost acceptance of high efficient insulation appeared to be low • The vision 2020 • Local governments, local energy supplier(s) and house owners are implementing long term plans for refurbishment and heat supply of the buildings • Energy efficiency (i.e. mainly insulation) is priorized Clemens Schneider

  11. Energy efficiency technologies: electricity demand • Efficiency potentials when using best available technologies (BAT): • Office equipment: LED (monitor lighting) and „thin client“ computers • Lighting (LED): 90% (long term) • Cooling & Refridgerating: 30% • Dish washers: up to 50%*) • Cloth washers: up to 50%*) • Cloth driers: up to 50% (using heat pumps) • Motors & pumps (≈ 30%) • Energy savings of 20% until 2020 are economical • But: all households involved (very many actors) • *) when connected to central warm water supply Clemens Schneider

  12. Low carbon technologies in Transport • Technologies to foster system efficiency of transport • Extension and more efficient use (telematics) of rail (and light rail) infrastructures to support modal shift to railways • Efficient drive trains: • Internal combustion engines (ICE): downsizing • Electrification of drive trains: recuperation of braking energy, use of renewable electricity in plug-in-hybrid vehicles (PHEV) • Light-weight construction • Information & communication technology to support “smart mobility” (using the most efficient transport mode available) • preconditions for major changes in mobility have to be organized locally • Excursus: Air traffic will be part of EU Emission Trading System from 2013 on. However, airplanes are long term investments (≈ 40 years) and will thus be replaced only slowly in the fleets. Clemens Schneider

  13. Conclusions Technologies and cooperation:local action and acceptancCe • Central structures with large scale technologies may be organized easier top down but the impact of the used technologies is locally concentrated and they are more vulnerable to path dependance • Decentral low carbon energy technology solutions are mostly well-proven • Strategic behaviour in carbon markets is less likely when there is a plenitude of players • Cities are identified to be the adequate level to organize stable and sustainable energy supply according to specific local demands:not self-reliant but self-determined Clemens Schneider

  14. Example “Innovation City Ruhr“: a “social laboratory“ • Public private partnership to try out fast diffusion of energy technologies in a part of the German Ruhr Area (former centre of German coal & steel production) • Scope: 50,000 inhabitants • Effective solutions shall be transferable to other cities in the area and abroad • City of Bottrop has been chosen in a competion process • Aim to reduce CO2-emissions by 50% until 2020. • Core areas of action: • Refurbishment • Energy efficiency in commerce and industry • Public Transport and electric mobility • Decentral energy supply Clemens Schneider
