Renewable vs Nonrenewable
This renewable energy sources uses heat from inside the earth
Geothermal energy
This mining meathod digs large holes into the ground
Open-pit mining
Water is heated into this before spinning turbines to create electricity
STEAM
This renewable energy source uses sunlight to create energy
Solar Energy
These bulbs use less electricity than traidtional bulbs
LED Bulbs
This fossil fuel is mainly used for transportation and gasoline
Oil/petroleum
This sticky semi-solid petroleum material is found in tar sands
During electricity generation, this greenhouse gas is released when fossil fuels burn
CO2
This alternatve fuel creates water vapor as its main emission
Hydrogen Fuel Cell
What is peak demand?
This occurs when electricity demand becomes very high (usually mornings and evenings)
What are the 3 major fossil fuels?
Coal, oil, and natural gas
This term describes leftover waste material often stored in ponds
Tailings
Coal power plants are ____% efficient?
36-40%
This nonrenewable energy source uses uranium
Nuclear Energy
This happens when electricity demand becomes greater than the supply
rolling blackouts
Explain why wind and solare are considered intermittent energy sources
They depend on weather/time of day
This term describes commerically valuable concentrations of minerals
ORE
Put the steps of electrical generation in order:
Generator, combustion, turbine, steam
Combustion, steam, turbine, generator
This renewable energy source can block fish migration and flood habitats
This effect causes cities to become warmer than surrounding rural areas
Urban heat island Effect
Explain why biomass is renewable but can still be envrionmentally harmful
Biomass can be replensihed, but overuse can cause deforestation and pollution
Name 2 envrionmental impacts of mountaintop removal mining
Habitat loss, erosion, stream burial, particulate pollution
What is co-generation?
Using fuel to generate electricity PLUS heat!
Tell me one small scale and one large scale energy conservation example
Small-scale = individual actions like LED bulbs; large-scale = government/public transit programs
What are two ways you could build passive solar into a house?
plant decidious trees, south facing windows, energy efficient windows, insulation and sealing, or rain barrels
