3. Meeting the energy challenge

4. Megatrends are causing a rise in Energy Demand URBANIZATION +2.5B people in cities by 2050 Source: United Nations, DESA DIGITIZATION Source: Cisco 50B connected things by 2020 INDUSTRIALIZATION +50% Energy consumption by 2050 Source: IEA

5. Resources in the next 40 years Energy consumption will grow by 50% CO2 emissions need to be halved ×1 ÷2 We have to become 3 times more efficient 3×.5 Note: Forecast for 2050 compared to 2009 levels

6. Required ‘energy transition’ will profoundly change the energy ecosystem The grid is aging in developed countries. Some of the country’s existing electrical infrastructure dates back to late 1800s. 27% increase in global energy consumption from 2000 to 2035 (source AEI BP stat review) 70% of new installations will come from solar and wind between 2012 and 2040
