1 Faculteit Techniek, Bestuur en Management Technische Universiteit Delft 1 Topics & teachers

2 Faculteit Techniek, Bestuur en Management Technische Universiteit Delft 2 Introduction basic physics and electricity energy and power current voltage power Boyle: chapter 1 Boyle: Appendix A2: Units and conversion factors

3 Faculteit Techniek, Bestuur en Management Technische Universiteit Delft 3 summary Energy sources : solar = x world energy consumption Geothermal also huge ( in fact nuclear source) Earth moon gravitational system. Potential energy plus kinetic energy. Also huge Fossil energy : limited: ~40 to 300 years of supply (conventional fields) Gas hydrates (~1000 years of supply) scale gas (not exactly known but also large >100 years for sure)

4 Faculteit Techniek, Bestuur en Management Technische Universiteit Delft 4 summary Energy paradox in spite of the huge availability of renewable energy it is very hard to develop fully RE systems. Energy scenarios Energy balance and mass balance 1e law of thermodynamics: energy conservation: E in = E out 2nd law of thermodynamics :  S > 0 power = energy per unit time The non-equilibrium situation ‘ wants’ to move to an equilibrium, than something is moving or flowing from which energy can be extracted. Examples hydropower, salt and freshwater, electric potential difference.

5 Faculteit Techniek, Bestuur en Management Technische Universiteit Delft 5 summary potential energy: E pot = m. g. h ; g=earth acceleration 9.8 m/sec 2 electric energy: E el = q.V q= charge [Coulomb]; V=potential (Volt) Electric power: P = E el /sec = (q/sec).V = I.V ; I=current [Amp] Chemical energy: enthalpy  H (kJ/mole) nuclear E = mc 2

6 Faculteit Techniek, Bestuur en Management Technische Universiteit Delft 6 summary potential energy: E pot = m. g. h ; g=earth acceleration 9.8 m/sec 2 electric energy: E el = q.V q= charge [Coulomb]; V=potential (Volt) Electric power: P = E el /sec = (q/sec).V = I.V ; I=current [Amp] Chemical energy: enthalpy  H (kJ/mole) nuclear E = mc 2
