How, in most cases, is electricity produced? -
What is the difference between alternating current and direct current? -
Who was the "champion" of current and direct current? -
In the early stages why did AC win out in the current wars? -
What was the early use of electricity that enhanced economic development? -
The difference between load and demand - Load= overall demand
Demand=
How demand differs from overall demand and sector-based demand. - Residential=2
peaks, 1 in morning, one in afternoon
Commercial=peaks during day
Industrial=static
Why demand is an important part of infrastructure development. - Drives the investment
in the infrastructure
Nuclear - Significant amount of storage
Coal / oil - Combust some kind of fuel
Natural Gas - Turbine is stationary, combustion cycle directly spinning the turbine
Jet engine directly connected to generator
No H2O
Natural Gas Combined Cycle - Lot of heat, put heat through H2O to create steam and
pushes turbine
, Why is NG different than coal, nukes and other thermal sources? -
Hydro -
Wind -
Fuel Cells -
Solar -
Geothermal Electricity -
Concentrated Solar. -
What is different about solar and fuel cells than other forms? - No moving parts on solar
Not a lot of maintenance
Three major components of the grid and their relation to billing/investment and regulation -
Transmission - Big lines
Allow utilities to have monopolies
Regulated by the regional level
Generation - unregulated
Distribution - States regulate it
How can we say some fossil fuel plants have "storage" versus other plants (such as natural gas)?
Why is this important? -
What are some of the environmental and sustainability impacts of our energy decisions?
Consider the following: . -
Generation. - Combusting releases emissions
Wind- Sound, bats and birds, aesthetics
Solar- taking up fields
Extraction - Pollutant
Disposal - Coal Ash
Resiliency and Security - Having one grid can get hacked
