Published on

Een presentatie van Ad van Wijk, duurzame energie ondernemer en buitengewoon deeltijdhoogleraar "Future Energy Systems" aan de TU Delft, over de trends binnen het energienet. Waar wordt energie verspild? Gebruiken we energie op de juiste manier voor bepaalde toepassingen zoals mobiliteit, verwarming en verlichting? Wat voor rol heeft de keuze voor AC-stroom ten opzichte van DC-stroom in de inrichting van ons energienet? Hoe kan dat slimmer en efficiënter?

Gegeven op dag 5 van Soundbites by Merford met als thema: Smart Grids.

Ad van Wijk - Trends in Energy; All electric, smart, DC

  1. 1. Trends in Energy;All electric, smart, DCProf. Dr. Ad van Wijk14-06-201219-11-2012 Delft University of Technology Challenge the future
  2. 2. There is no energy crisis• Energy efficiency world wide is about 2%• The sun gives us in one hour more energy than the world consumes in a year• Renewable energy is everywhere but dispersed Lezing door Ad van Wijk – Soundbites by Merford - Dag 5: Smart Grids 2
  3. 3. Our CarLezing door Ad van Wijk – Soundbites by Merford - Dag 5: Smart Grids 3

  8. 8. Where do we use energy for?World wide energy consumption % of totalClimate (heating, cooling,..) 25 - 30Transport 25 - 30Electricity 15 - 20Other 25 - 30 Lezing door Ad van Wijk – Soundbites by Merford - Dag 5: Smart Grids 8
  9. 9. Trends in Energy; All electric, smart, DC• Energy producing buildings• Clean Light• Electric Transport• Local energy production• Smart DC electricity grid• The Car as Power Plant Lezing door Ad van Wijk – Soundbites by Merford - Dag 5: Smart Grids 9
  10. 10. Energy producing buildings• Energy use for heating and cooling our buildings is roughly 25% of all energy.• But why do we use energy in our buildings? • In winter time it is too cold and we have to heat our buildings • In summer time it is too hot and we have to cool our buildings• It is not an energy problem it is a storage problem Lezing door Ad van Wijk – Soundbites by Merford - Dag 5: Smart Grids 10
  11. 11. The Closed GreenhouseTotal control of temperature, humidity and CO2 levels in a greenhouseAdvantages:• Produce, not consume, energy• re-use of irrigation water 90%• reduced use of pesticides 90%• increased crop production 25%• improved process control Lezing door Ad van Wijk – Soundbites by Merford - Dag 5: Smart Grids 11
