Energy & Electricity History of Electricity/Grid “Making” electricity Electricity delivery Making electricity not efficient

Pack, Sabrina, Operations Manager has reference to this Academic Journal, PHwiki organized this Journal Energy & Electricity History of Electricity/Grid Electricity “system” created in US 1881 Purpose was electricity as long as lights 1881 cost: $0.24/kWh! (now ~$0.10) Early 1900’s: inter-city transmission lines 1930s-1950s: rural electrification, federally-run electric generating plants (hydro) 1950s- now: nuclear power, environ. controls, fuel costs, Three Mile Isl in addition to “Making” electricity For wind & hydro, skip step 1 For PV solar skip 1 in addition to 2 coal, natural gas, nuclear fission, wood, solar energy steam, water, air Boiler (1) (2) Turbine Generator (3)

Electricity delivery Making electricity not efficient Doesn’t include losses along transmission lines, another 5-10% Coal-fired electricity Pros Cheap Abundant New technologies to help with emissions Cons Resource finite Emissions Carbon SOx NOx Particulate Matter Mercury Mining Health & environment Transportation

Natural gas Pros Cleaner than coal Dispatchable “Combined cycle” makes plants more efficient Cons Costs variability & uncertainty Emissions Supply questionable

Nuclear power Pros No CO2 emissions Cheap Abundant fuel 3% of all topsoil is U235 Cons Cheap High impact/low occurrence risk No closure to life cycle Waste, Yucca mountain Security

Hydroelectric power Pros Emissions very low Opportunity as long as storage Cheap Flood control Water supply Cons Devastating to wildlife in addition to surrounding area Owner has control of the river downstream Dependent on weather

“Renewables” Solar, Wind, Thermal, Tidal Pros Low emissions Resource requirements low Energy independence Cons Costs Intermittency Location Not necessarily renewable

What’s your consumption mix Consumption mix: the fraction of each type of generation a specific region, state, business, or individual consumes Can then figure out what the environmental impact of that entity’s consumption is Split up into 4 groups

What in as long as mation do I need Type of nearby generators Power plants, dams, windmills, solar arrays Proportion – amount of total generation made up by each type 40% type A, 30% type B, 30% type C Regions: NW, NE, SE, SW Generation Types: Coal Natural Gas Petroleum Nuclear Hydroelectric Solar Wind Geothermal Biomass Other Guesses as long as your region

Other social costs Air St in addition to ard pollutants Hg, Se, Cd Water Acid mine drainage Water system disruption Fishing Waste Spent batteries in addition to cells Spent nuclear fuel Safety issues Rail Pipelines Turbines Aesthetics Wind turbines Steam Transmission lines Smog Externality: “Costs that society must pay which are not borne by the producers” In green design, we try to find ways to generate the positives associated with electricity without the negatives Advanced nuclear Carbon sequestration Combined heat & power Large scale renewables Distributed generation 3 things you can do to help: Conservation every unit of output you save means 3 units of input saved Conservation pay attention to things around you which consume power Conservation make power consumption a factor in deciding which things you purchase
