Definition of Energy4BC - energy derives from Greek ἐνέργεια (energeia) = activity, operation1600s - Gottfried Leibniz (vis viva) product of the mass of an object and its velocity squared 1807 - Thomas Young 1st to use the term “Energy”
Primary Energy Secondary Energy
Energy consumable
Energy expanded
Net Energy (NEG) = EnergyConsumable − EnergyExpended
DefinitionLow energy - uses less energy, from any source, than a traditional or average
contemporary house Passive - require little energy for space Zero - zero net energy consumption and zero carbon emissions annually
(requires the use of onsite renewable energy technologies ) Net zero - produces as much energy as it uses over the course of a year Plus Energy – produces more renewable energy than it consumesEnergy Conservation – usually comes in the form of codes and standards

Exergy?ENERGY is motion or ability to produce motionEXERGY is work (= ordered motion) or ability to produce work. When exergy reaches the earth, it is gradually destroyed, but on the way it manages to drive, among other things, the water/wind system, and life on earth

Relationship between Spatial distribution and Energy
Future of Energy• If energy cant be created nor destroyed why is there an energy
crisis?• Perhaps we need a better quality of exergy. Thus, leading to the
creation of new energy technologies and way of life of the future.
