Transport: opportunity & challenge
11Energy Efficiency/ICT
e-Mobility
- 60% of world oil consumed in transport
- Electric drive much more efficient than combustion engine
- Cost of electricity/km 3-4 times lower than petrol/km
Technological Challenge
- Battery technology
- Charging
Electronics in electric vehicles
12Energy Efficiency/ICT
Solution: NRGspot – a Public Ultra-Fast Charging Infrastructure
- Based on Lithium-ion batteries and
advanced power electronics
- Charging systems provided by Epyon
(spin-off of TU Delft)
- Charge points located at strategic
places (near shopping centres),
supply 100% green electricity
- Access open to subscribers via
intelligent interface
- Ultra-fast charging within 5-60 min.

14Energy Efficiency/ICT
Electric Drives
- Electric drives account for 65% of industrial electricity consumption
- Converting to variable speed drives permits almost 50% reduction
- Most important area of application: pumps and fans
Technological Challenge:
- Flow / pressure control

16Energy Efficiency/ICT
Solution: Variable Speed Drives
Example: Pietarsaari’s water supply
- 30% reduction of energy consumption
- Water pressure much more stable
(reduces leaks, maintenance needs,...)

The Future
19Energy Efficiency/ICT
“given the right mix of investment‐led policies that drive what we call a 
Semiconductor‐Enabled Efficiency Scenario, the market could facilitate 
productivity gains that reduce electricity use below current levels ”
