Document Summary
300 years ago - local energy sources concentrated/traditional energy - versatile, transportable, worldwide. Advantages : how concentrated it is, versatility, safety, availability. 20% of world"s population use 60% of world"s energy sources. Us consumption : 20% of world total energy (2014) Offices : superinsulation; south facing windows; insulated glass; no furnace; zero net energy buildings (produce as much/more energy than consumed) Power companies - demand side management; benefits customer + electric company. Cash rewards/incentives to customers with energy efficient technologies. Energy companies: give away free energy efficient appliances + tools. Losses : combustion as heat; braking, idling, friction with road, moving weight of car, bad driving habits (waste gas) Industry : cogeneration: production of two useful forms of energy from the same fuel. National appliance energy conservation act (naeca) - national efficiency standards for appliances. Allow product prices to reflect true cost of production (energy costs) Electricity : the flow of electrons in a wire.
