Climate Change and our insatiable appetite for energy • This series is looking at the Environment, Climate Change and Global Warming. • Last week we saw that Climate Change is partly natural, but most effects in last 50 years have been from man’s activities – burning of fossil fuels for energy • Today’s talk will review what resources and their potential for the next 50 years. • Next Week we will go on to consider the hard choices facing us • Then: what can we do about it? • what should we as Christians do about it? • Keith Tovey (杜伟贤) M.A., PhD, CEng, MICE • HSBC Director of Low Carbon Innovation: • School of Environmental Sciences • Lay Chairman, Norwich East Deanery CRed

POTENTIAL OF ENERGY RESOURCES CURRENT AND PROJECTED USAGE Projected Saturation Population in 2050 -- 10000 M consumption averages current UK value Requirement in 2050 = 50 TW 50 billion kW. consumption reaches current USA value Requirement in 2050 = 100 TW i.e. 10 times current demand Range of forecasts 20 - 100 TW with a likely value in range 30 - 50 TW (say 40 TW).
To discuss now • Is 10 billion a realistic assumption for population? • Or will Bird Flu solve our problems and halve that figure? • Does 4 kW per person seem reasonable - 80% of our current level, 70% of European Level, 40% or US level • What exactly do we mean by renewable energy resources? • Are any of the following resources renewable? • Geothermal, Peat, Hydro?? • Gas, Oil, Coal??

PROJECTED LIFESPAN OF RESOURCES 1 trillion = 1 million millions decades:- centuries: millennia: projected average consumption of 40 TW annual consumption will be:- 350 trillion units (kWh) at present it is 90 trillion units Compare this to the Current World Proven Reserves:- Oil Reserves:- 1500 trillion units Gas Reserves:- 1500 trillion units Uranium:- 1000 trillion units Coal Reserves:- 7000 trillion units Uranium (Fast Breeder):- 25000 trillion units Fusion (Deuterium):- 275 billion trillion units Oil Shales 235U, Oil, Tar sands, Gas, Coal, Geothermal, 238U, D – T fusion, 232Th D – D fusion
"RENEWABLE ENERGY RESOURCES" Orders of magnitude only Practically Achievable:- 10 - 50 million kW – Tidal 100 – 500 million kW - Geothermal; OTEC; Biomass; Wastes 1 – 5 billion kW - Hydro; Wind; Waves 10 – 50 billion kW – Solar We will need all the renewables we can get Projected demand is 40 billion kW
