1 Park Lane Methodist Church Sunday 14 th May 2006 Climate Change and the Environment Keith Tovey Н.К.Тови М.А., д-р технических наук Energy Science Director CRed Project Our Insatiable Appetite for Energy POTENTIAL OF ENERGY RESOURCES 14

2 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 mans activities – burning of fossil fuels for energy Todays 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 ( ) M.A., PhD, CEng, MICE HSBC Director of Low Carbon Innovation: School of Environmental Sciences Lay Chairman, Norwich East Deanery CRed Climate Change and our insatiable appetite for energy

3 Climate Change: Arctic meltdown Summer ice coverage of Arctic Polar Region –Nasa satellite imagery Source: Nasa 20% reduction in 24 years CRed Climate Change and our insatiable appetite for energy

4 POTENTIAL OF ENERGY RESOURCES CURRENT AND PROJECTED USAGE Projected Saturation Population in 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 TW with a likely value in range TW (say 40 TW). CountryEnergy Requirement PopulationPer Capita World12.0 TW6000 M2.0 kW USA 3.0 TW 300 M10.0 kW Europe 2.0 TW 350 M5.7 kW UK 0.3 TW 60 M5.0 kW

5 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?? To discuss later Are there differences in our meaning of Renewable with Solar, Wind, Biomass? What is needed to bring our use of resources into harmony with nature on Gods planet? To discuss now Is 10 billion a realistic assumption for population?

6 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: trillion units Gas Reserves: trillion units Uranium: trillion units Coal Reserves: trillion units Uranium (Fast Breeder): trillion units Fusion (Deuterium):- 275 billion trillion units D – D fusion Coal,Geothermal, D – T fusion, 232 Th 235 U, Tar sands, 238 U, Oil Shales Oil, Gas,

7 "RENEWABLE ENERGY RESOURCES" Orders of magnitude only Practically Achievable: million kW – Tidal 100 – 500 million kW - Geothermal; OTEC; Biomass; Wastes 1 – 5 billion kW - Hydro; Wind; Waves 10 – 50 billion kW – Solar Projected demand is 40 billion kW We will need all the renewables we can get

8 POTENTIAL OF ENERGY RESOURCES TheoreticalPracticalRealised to date TWGW NON- SOLAR Tidal3501France, Russia, China 1 TW = 1 billion kW 1 GW = 1 million kW

9 4. POTENTIAL OF ENERGY RESOURCES GW TW Realised to date PracticalTheoretical France, Russia, China 1503Tidal NON- SOLAR Italy, Iceland, USA, New Zealand Geothermal 1 TW = 1 billion kW 1 GW = 1 million kW

10 POTENTIAL OF ENERGY RESOURCES GW TW Realised to date PracticalTheoretical France, Russia, China 1503Tidal NON- SOLAR Italy, Iceland, USA, New Zealand Geothermal USA, Israel: third world 10*30000 (on land) SOLAR Direct Normal hot water circuit Solar Circuit Solar Pump

11 POTENTIAL OF ENERGY RESOURCES - Solar House in Lerwick, Shetland Isles - less than 15,000 people live north of this in UK! It is all very well for South East, but what about the North?

12 POTENTIAL OF ENERGY RESOURCES TheoreticalPracticalRealised to date TWGW SOLAR Indirect Wind and rising rapidly USA, Denmark, Germany, Netherlands, Spain ~ 1500 MW in UK 1 TW = 1 billion kW 1 GW = 1 million kW

13 POTENTIAL OF ENERGY RESOURCES 1 TW = 1 billion kW 1 GW = 1 million kW

14 POTENTIAL OF ENERGY RESOURCES GW TW Realised to date PracticalTheoretical USA, Denmark, Germany, Netherlands, Spain ~ 800 MW in UK 20 and rising rapidly Wind SOLAR Indirect

15 POTENTIAL OF ENERGY RESOURCES GW TW Realised to date PracticalTheoretical USA, Denmark, Germany, Netherlands, Spain ~ 800 MW in UK 20 and rising rapidly Wind SOLAR Indirect UK, Norway, Japan Waves USA OTEC Pelamis: 750 kW device installed August 2004: Orkney Operated for 10 days – was in dock for 9 months at Lyness 1 TW = 1 billion kW 1 GW = 1 million kW

16 POTENTIAL OF ENERGY RESOURCES TheoreticalPracticalRealised to date TWGW Hydro USA, Brazil, Canada, Scandinavia, Switzerland, Malaysia etc. Biomass/ Wastes ?Various Brazil - Bioethanol SOLAR Indirect Transport Fuels: Biodiesel? Bioethanol? Hydrogen????

24 View from Thorpe Station The STAR will be 50% higher than the pylons which will be demolished

25 To discuss Are there differences in our meaning of Renewable with Solar, Wind, Biomass? What is needed to bring our use of resources into harmony with nature on Gods planet?
