10. World’s need for energy likely to double before 2050.

11. Alternative energy sources needed, but insufficient.

12. HC fuels continue to be needed for primary energy.

13. Demand will exceed supply for HC’s in 3-5 decades.

14. Conservation may provide ~25 years more time.

15. Scale of required infrastructure is immense.

16. Use of HC energy leads to concern with atmospheric CO2Conclusion Human society faces a serious challenge for energy supply with concommitment to environmental sustainability 9

17. 10 Needed Conservation to gain time. Smart, intensive, and extensive engineering to address the huge scale of infrastructure and operational requirements. Transformational research to develop ultimate source(s) of primary energy. Coordinated developments to insure environmental sustainability. Sense of urgency. 10
