  1. Arab Climate Resilience Initiative The Pursuit Towards Sustainable Energy- Resources, Challenges and Opportunities A Quest for Another Perspective ……… Sarfraz H DairkeeLEED AP, CEM, CEA, CBCP, PSAT

  2. Unlimited Demands

  3. Limited Resources

  4. What is the solution ?

  5. The Engineer’s View Supply Management Generate more electricity by increasing production or improving efficiency of conventional technology.

  6. The Economist’s View Demand Management Reduced Demand By Increasing Price

  7. Are these the only ways? Are we forgetting something?

  8. What we are forgetting is that all the forms of energy are not equal or alike. Some forms of energy may be better suited to be directly applied to demands rather than through conversion to and expenditure of electricity. Matching appropriate energy supply to end use is the answer.

  9. Broadening Our Perspective Why is it that we only think of electricity when considering Energy? Energy = Exergy + Anergy Electricity is the highest form of energy; it is Exergy itself. Practically, due to imperfect efficiency, electricity usage leads to both Exergy and Anergy.

  10. Are we forgetting something again ? ? Consumers don't demand energy, they demand goods and services. Electricity is not an end in itself. It is only ONE of the means of ensuring delivery of these needs.

  11. The other ways… There are various other forms of energy available to our disposal such as solar, wind, hydel, tidal, diurnal differentials Conventional wisdom is to use these renewable forms to generate electricity.

  12. The quality of different forms of energy

  13. Energy Exergy Efficiency

  14. The 'Energy Crisis' does not stem from a lack of energy… …but from a failure to match forms of energy to the real requirements of the consumer Amory Lovins

  15. The Softpath ApproachProposed by Amory Lovins A soft energy path is one that is pliable, one that matches the energy source to the energy demand. There is no demand for electricity, oil or Uranium. The demand is for needs and comforts. The soft path approach is about supplying the most appropriate energy in the most energy efficient way to meet those needs directly.

  16. Features of Soft-energy PathsProposed by Amory Lovins • - Rely upon natural energy flows • - Are diverse, thus not over-dependent upon any one source • - Are flexible using local resources and materials • - Are matched in scale to end use needs • - Are in harmony with environment aligning with nature rather than controlling it • - Are matched in energy type and quality to end use needs • - Are resilient

  17. Practical applications forbuilding designs in the Middle East Indoor illumination and water heating using solar insolation. Natural ventilation using wind energy to ensure healthy indoor air quality. Temperature control and cooling using diurnal variation of humidity, temperature and wind conditions.

  18. To sum it up… Think beyond electric/grid power. There’s more to energy than electricity. High Exergy solutions may be the most convenient but are not the most optimum and sustainable. Matching appropriate forms of energy directly with needs can yield significant efficiency gains. The environment is your ally. Work with it rather than against it!

  19. We must remember that … ‘There is no free lunch’ let us try that our future generations do not have to pay for our mistakes. Elegant and Sustainble Solutions are at the "Bottom Of Exergy Pyramid" Promising Sustainability with Harmony and Quality of Life
