ADEME Energy and Climate Visions 2030-2050 Eric Vidalenc – Economics and Foresight Department ADEME - French Agency for Environment and Energy Management Objective and context • Objective of this morning session : • Focus on methods used to frame scenarios (less on emphasizing the outcome of a given model or approach) Example: ADEME Visions 2030 2050 • Context : work launched by the President of ADEME in 2012 (ADEME CEO F.Loos before the DNTE – National debate leaded in 2013) • A collaborative exercise (a small coordination team and about sixty experts involved) • Visions…and not scenarios (roadmap with political steps…) built on our core skills : renewable energies and energy efficiency. • 4 tools/models used for quantification issues : • Technical : MEDPRO • Electrical system: EOD • Agriculture and land use : Mosut • Macroeconomic evaluation : 3ME 2 Visions 2030 2050 :A kind of tryptic • A technical description (2012) • A social translation in the daily life of households (2014) • A macroeconomic evaluation (2013) 3 Two Visions Same scope… • Energy consumption: buildings, transportation (but international air and maritime bunkers), agriculture and industry • Renewable energy production …yet distinct perspectives • 2030: current trends « + » a significant increase in energy efficiency and renewables : exploratory , « what if », foresight, positive method • 2050: the 75%-decrease-target is set, then achievement conditions are identified : « how » to reach it, backcasting, normative method • At last, there is an issue to identifie a possible gap between the 4 two perspectives Methodology Technical scenarios (model : MEDPRO, MOSUT, EOD) 1. Inventory of renewable resources and energy efficiency potential with sectoral experts 2. Definition of a set of possibilities, with respect to technical and economic criteria (ROI identified) 3. Identification of values and consistency checking 4. Energy consumption and renewable energy production projections Economic conditions and macroeconomic impacts (model: THREEME) 1. Identification of necessary price-signals 2. Simulation of the macroeconomic impact Social translation 1. Identification of type of households to describe 2. Quantification of all the daily actions in terms of energy and CO25 Summary Distinct perspectives • 2030: an ambitious yet realistic vision • 2050: a 75%-decrease (compared with 1990) in GHG emissions Focus: energy (consumption and production) and GHG emissions Key-messages • 2030: energy efficiency and the share of renewables could increase significantly • 2050: the fourfold decrease in GHG emissions is achievable with efficiency, renwables and some change in our habits and behaviour Remarks • Sources of figures 2010: INSEE, CCTN, SOeS, CEREN 2030 - 2050: ADEME estimates (but exogeneous variables) • Reference years: 2010 for energy; 1990 for GHG emissions 6 Main results Energy GHG emissions • -40% by 2030 • -75% by 2050 7 Exogeneous variables vs ADEME’s assumptions Exogeneous variables Macro 2010 2030 2050 References Population (m) 62.9 68.5 74.1 INSEE Number of person/household (*) 2.3 2.17 2.05 INSEE Brent (US$2010/bbl) 78 135 230 IEA GDP (%/year) New homes (m/year) Sectoral 1.8% 0.310 Energy-intensive industrial output (t/year) Share of nuclear power 0.35 CAS 0.3 depends on the product 77% 48% DGEC DGEC 18%-48% (*) henceforth « hh » ADEME’s assumptions • Unit consumption: energy efficiency • Demand: organizational efficiency, non-disturbing changes in ways of living (ex: miles/year/cap, number of TV sets/hh, etc.) 8 2030 - Residential Urban planning: share of multi-family new buildings increases (from 42% in 2010 to 50%) Thermal uses • Energy-efficient retrofitting: 0.5 m homes/year • Comfort: unchanged, if not improved (e.g. air-conditioning) • Equipment Heat-pumps (20% of space heating useful energy consumption), Thermodynamic water-heaters, solar water heaters (5% of hot water useful energy consumption) Electrical appliances: • Stock of conventional appliances (fridge, washing-machine, TV,etc.) as efficient in average in 2030 as today’s most efficient appliances • Complementary electricity consumption (cell phone, IT’s, etc.) is constant (1,000kWh/year/household) 9 2030 – Residential - Results Per-use consumption Type of delivered energy 10 2030 – Commercial and public services buildings Organisation: floor area/employee is constant Thermal uses • Building stock thermal performance and equipments are significantly improved • Comfort is increased (50% of employee work in air-conditioned buildings) Business-related electricity consumption • 10% decrease per employee by 2030 compared with 2010 Result: a 16% decrease in final energy consumption 11 2030 – Transportation Paradigm: constant individual mobility and modal split Freight: a 20% increase in transported mass (tkm) 12 2030 – Transportation Passenger transportation: emergence of mobility services (account for 10% of intra-city passenger flows ) Results in terms of sales and stock : 13 2030 – Transportation - Results Final energy consumption Type of energy 14 2030 – Industry Assumption: industrial recovery • Energy-intensive products: pre-crisis (physical) output quantity is recovered, if not slighlty increased • Other industries: grow roughly according to GDP growth Energy-efficiency: 20% in average (less than 1%/year) 15 2030 – Industry - Results Recycling (materials as well as heat losses) taken into account Result: a 10% decrease in final energy consomption 16 2030 – Food, forest and agriculture No-regret changes of habits • A 2/3 decrease in food wastages • Current trends are protracted (e.g. decrease in meat consumption) Energy efficiency: a 25% decrease in energy consumption of agriculture buildings, 20% decrease use of synthetic nitrogen fertilizers Land management : land sealing pace is two-fold decreased, + 0,2 Mha of forest in 2030 Results : - 11% in livestock related impacts (CH4, N2O), and an low decrease in energy consumption 17 2030 – Energy production (1) Resources: • Solid biomass and methanization are both significantly increased • Land use competition is not exacerbated (3Mtoe of biofuels, compare to 2,4) 18 Renewable power 2030 – Energy production (2) Focus on electrical system • Wind: On-shore (34 GW) and off-shore (12 GW) • PV: 33 GW (very close to RTE New mix in terms of installed capacity but with 20% less on demand) Remark: the load curve hourly matches power generation 19 2030 – Energy production -

TNO Method : Define a baseline reference scenario, consider the technical assumptions 28 • Signal-price / Carbon tax • Energy balance • 325€/tCO2 in 2050 • Total : 750€/tep in 2050 (must be compared to the current implicit tax level : 243€t/CO2 on gasoline) 29 Investments 30 • GDP • Jobs 31 Concluding remarks Beyond energy and GHG • NOx, SO2,PM2.5 and COVNM three-fold decreased by 2030 • Likely (yet not quantified) reduction in other externatities : • Transportation: noise, road casualties, congestion, health (cycling) • Buildings: thermal comfort • Food: meat-overconsumption-related deseases Economics • An additional 300€/tCO2 price-signal is required by 2050 (in ADEME scenario, not in absolute terms) • Macroeconomic impacts: • Recessionary: increase in energy prices (loss of competitiveness) and decrease in conventional energy production • Expansionary: decrease in fossil energy imports, increase in new business activities (renewables, high-quality building retrofitting) 32 • THREEME-based macroeconomic simulations show that the global impact on both GDP and employment is positive by 2050 Social translation Just released • A description of the daily life and behaviour of 8 families in different context (age, children or not, localization, income…) • 4 pages of narrative description and an energy balance (kWh and CO2) for each household compatible with the global ADEME vision 33 Attempt to conclude : Science for energy scenarios ? • Scenario is a way (with differents tools) to look forward • And if science is : • Rigorous and checkable method investigation • Open to criticism and discussions • Probably Yes • But if science is : • Reproductible … • Maybe not • Because between two periods : we can see huge changes in knowledge, technologies (V2G, PtG…), values, belief, learning cost curve… 34
