Text of Urban Self Sufficiency with sustainable energy and clean mobility (ICLEI World Congress 2009)

  • Urban Self-Sufficiency with Sustainable Energy & Clean Mobility

    Gustav R. Grob. F.IP (F.EI)International Sustainable Energy Organization ISEOChairman ISO/TC203/WG3 Energy Systems Analysis

    President International Clean Energy Consortium ICEC

  • The complexity of the future global sustainable energy system intelligently interlinking a multitude of decentralized clean energy sources with efficient

    stationary users and electric vehicles with millions of buffer batteries

  • Energy supply for a growing population is facing fundamental change for three reasons:

    1 - The economic supply of the mineral energy resources oil and gas is ending in a few decades.

    2 - Health hazards, risks and global warming causedby emissions from combustion engines.

    3 - Imperative conservation of the fossil resourcesfor the chemical and metallurgical industries.

  • Prevention of catastrophic global warming by clean

    Global Warming Forecasts by prominent scientists of Meteorological Institutes

  • To cope with these serious problems, benign,

    renewable energy systems must be multiplied

    to replace conventional combustion

    Smart grid electricity is the ultimate concept

  • Geothermal EnergyBorehole systems

    a) Hydraulic fracturing by high pressure Brunnschweiler system with safely controlledwith relatively small energy yields closed primary water cycle in insulated well

    or andb) Boreholes to geothermal aquifers secondary steam turbine cycle with co-generation

    in open systems with limited energy for district heating, AC, greenhouses, industry

    Advantages:No yields by hazard ! Super performance (GW).No fuels or waste problems.Excavated materials re-used.Base load power plus heat

    Energy cost: 24 $/kWh

    Disadvantages:

    a) Water is finding way of lowest resistance= limited Energy yield

    b) Only in hydro geologic strata often far from consumers.Often high energy transport cost.Often limited to heat production only.

    Energy cost: 5-10 $/kWh

  • Advantages of geothermal deep well energy co-generation

    Produces electricity and heat (suitable also for AC) Much lower net cost than any other energy source Can be built near agglomerations and substations Less energy transmission line cost hence also

    less transmission losses than other power plants Invisible, no air or water pollution and no noise Ideal power source for clean electric vehicles No radiation risks or other health hazards Creates new clean sustainable jobs No waste disposal problems ! Lasts forever !

  • Typical locationsExample NRW Subsitution of Nuclear & Coal

  • Finite Nuclear Power (to be replaced)

  • Sucess Story: Barcelona Solar Ordinance

    One of the first cities to oblige owners to equip roofs with solar collectors ! To heat all the domestic sanitary water by solar energy it is necessary to cover

    1.62 % of municipal surface or 2.82 % of built surface, representing1.07 m2/capita > 2.4 m2/appartment > 20.15 m2/residential building

    Evolution of solar collector surface since ordinance enforcement:

  • Conclusions of the ISEO Energy Study1. There is more affordable renewable energy available on Earth than

    humankind ever needs at the foreseeable population growth rate.

    2. Most renewable energy systems like GEOCOGEN are competitive with the depleting non-renewable sources - even more so, if the full costing polluters-pay principle and smart grids are applied.

    3. All nations and cities are able to become energy self-sufficient with renewables and thus can drastically reduce pollution by cleaner, more efficient power plants and transport modes.

    4. The remaining finite mineral energy resources can and must be conserved for higher added value purposes in the chemical and metallurgical industries.

  • Transportation absorbs over 1/3 of World Energy Production

    i.e. over 50 % of World Oil Production

    European Shares of Energy for Transportation

    The bulk of energy is usedfor inefficient road transportationtoo many trucks and underutilzedcars with low-efficiency engines

  • SUSTAINABLE

    TRANSPORTATION

    OF THE FUTURE

  • Clean Rapid Mass Transit and inter-modal freight systems are indispensable for the efficient flow of people and goods in highly populated regions, but also clean and safe individual transport is required to satisfy the needs of humans living or working in remote, scattered locations and for their leisure time.

    Solutions are electric trains for goods and people, clean fuel trucks and ships for inter- modal transportation, cleaner aero-planes and efficient 2, 3 & 4-wheelers driven by clean fuels or electricity from RE sources.

  • Rapid Mass Transit Systems

  • vv People Transportation vvmust evolve towards combined Road-Rail

    Mass Transit Systems. Excellent example:the saving

    unproductive time of travellers, traffic fines, parking and fuel cost, pollution, reducing

    traffic congestion and improving social life among the passengers in transit

    Electric Swiss Rail Network

  • Example: Electric Schoolbus with Supercaps

    Inductive Re-Charging

  • Individual Transportis, however, one of the basic human urges.

    It must be satisfied for professional and leisure purposes. I characterized the car of

    the future 1992 in Rio as follows:

    Comfortable, Light, Zero-Pollution,Quite, Safe, Long-Life, Recyclable,

    Low Maintenance Cost& Modern Navigation System
