SOS 314 ~ Unit 1 What is Energy: Part 1  The Centrality of Energy graph o Primarily biofuels prior to Industrial Revolution o Have only been able to control fire for about 9000 years, feed w/ biomass (aka wood,  animal dung) o Haiti vs. Dominican Republican in terms of forestation o Domestic animals used for fuel/biomass for about 7000 years o Higher per capita income generally means more energy consumption o Uses for energy: growing food, making stuff, transportation, leisure, communication,  climate control (mainly electricity and transport)  Energy is ability to do work (force x distance) over time (kilowatt hours)  Power (watts) is the rate at which energy (unit of time too) is used o Need to know how long and at what rate for energy o Joule = 1 Newton meter = 1 watt/second o BTU (British Thermal Unit) = energy required to heat 1lb of water 1°F  Quads = quadrillion BTUs o calories and kilocalories (nutrition)  Sources of energy­ content and density o Coal and Twinkies o Deuterium (isotope of hydrogen) used in fusion, very efficient energy Energy, Work, and Power reading  Work = causing an object to move into or out of some position, especially when it moves  against a resistance (force x distance) o Resisting gravity, frictions, natural strength of material, or generating electricity  Energy = capacity to do work o Can't do work without energy, transfers  Power = time rate of doing work aka (work/time)  Power = charge/time x potential, current x pot, or energy/time Watts = Amps x Volts so P = IV Energy = power x time 2 P = ohm x I  When work is does, energy is wasted often as heat (resistance heating)  Transformers increase or decrease voltage, but Pin= Pout What is Energy: Part 2  Thermodynamics­ how heat moves o 1st law: energy can't be created or destroyed  But can become less useful, generally when form changed or moved across  distance  Power plant energy leaves as waste heat and hot water, only get about 2%  from incandescent light bulb o  2nd law: all systems tend toward entropy (chaos)  Entropy works against weinermobile as friction with air, ground, in engine  Phases of useable energy o Extraction (oil rig and coal mine) o Refining­ narrowing to what you need, standardizing o Production­ primary sources to useable (coal fired plant and nuclear plant) o Distribution (gas station, electric grid) o Consumption­ use of energy (transportation, charging electronics)  Capacity Factor (how often you can use an energy source)  Actual/ideal running time given as percentage  Large range­ solar may have 20% in AZ, geothermal may have above 90%  Turn down when demand is low, how much fuel is available (intermittent or amount  purchased), efficiency, cost of fuel, maintenance Additional Info  Friction means that energy is lost in the form of waste heat. Remember that it's not  destroyed! The more places that friction occurs on a device (such as between the device and  air, device and ground, or in between parts of the device), the more energy is probably lost to friction.  That's why bikes are more energy efficient than cars.  Capacity factor measures how frequently a power plant is ran and to what extent. This is  generally given as a percentage.
