6. 2 nd International Conference on Nuclear and Renewable Energy Resources Nuclear Fusion Energy – Mankind’s Giant Step, 4 - 7 July 2010, Gazi University, Ankara, Turkey S Lee & S H Saw 5 Trends in population growth and energy per capita consumption growth  AD 1500 World population (estimated) 450 million  AD 1900 1.6 billion [1]  End 2009 6.8 billion.  Past 100 years world population grew 4 times, whilst energy consumption grew 10 times.  Thus energy consumption grew faster than population growth;  in other words energy consumption per head grew more than 2 times.  This trend of per capita energy consumption growth will continue as the rest of the world attempts to catch up with the best standard of living in the world.

7. 2 nd International Conference on Nuclear and Renewable Energy Resources Nuclear Fusion Energy – Mankind’s Giant Step, 4 - 7 July 2010, Gazi University, Ankara, Turkey S Lee & S H Saw 6 Exponential Growth of Population and Energy Consumption  Past 100 years the doubling time of world population was 50 years  whilst the doubling time of energy consumption was 30 years.  Were this trend to continue, world population would reach 27 billion in another hundred years  whilst energy consumption would increase another 10 times.

8. 2 nd International Conference on Nuclear and Renewable Energy Resources Nuclear Fusion Energy – Mankind’s Giant Step, 4 - 7 July 2010, Gazi University, Ankara, Turkey S Lee & S H Saw 7 Exponential Growth is Unsustainable  Unsustainable; as the world is already near the critical point when supply of energy barely meets the demand.  Energy resources are limited and supply trends are estimated to peak in a few short decades from now.  This realisation underlies demographers’ projections that world population growth must slow down in the near future.

13. 2 nd International Conference on Nuclear and Renewable Energy Resources Nuclear Fusion Energy – Mankind’s Giant Step, 4 - 7 July 2010, Gazi University, Ankara, Turkey S Lee & S H Saw 12 Present Energy Resources not sufficient  All energy resources are being depleted by the exponential growth of population and of average world per capita consumption  New energy resources are not being developed fast enough  Renewables are too diffused: low energy collection density and poor net energy output; projection of renewables do not show the ability to sustain historical rates of human population growth combined with growth of per capita consumption.

14. 2 nd International Conference on Nuclear and Renewable Energy Resources Nuclear Fusion Energy – Mankind’s Giant Step, 4 - 7 July 2010, Gazi University, Ankara, Turkey S Lee & S H Saw 13 Incremental Steps Important but not Sufficient- New Source needed  What Mankind needs is not small increments extracted from energy conservationism or diffuse renewables  What Mankind needs is one Giant Step A new clean limitless energy source

49. 2 nd International Conference on Nuclear and Renewable Energy Resources Nuclear Fusion Energy – Mankind’s Giant Step, 4 - 7 July 2010, Gazi University, Ankara, Turkey S Lee & S H Saw 48 The Scenario-with Fusion Energy  Just into the next century fusion energy will take up the slack and allow Mankind to continue its progress and growth (curve 2, available energy, with fusion energy).  The scenario shows that there will be several decades when the constraints of energy shortage will be severely felt. Note the flattening of the energy consumption from around 2040 to 2100. (curve 2, with fusion energy).  Such a period of stagnation in energy and corresponding stagnation in world population (curve 4 showing world population scenario, with fusion energy) seems unavoidable even with the development and rapid adoption of fusion energy.  Without fusion energy the scenario is as shown by the curve 1, depicting a severe downturn in the fortunes of Mankind with world population dropping below 5 billion (curve 3, world population scenario, without fusion energy).
