Unit 6 Flashcards
List the different types of resources to power the world
Coal, Biomass, Nuclear energy, fossil fules, hydrogen, hyrdoelectric, solar, wind, and geothermal
What is the most used renewable energy
Biomass
What is the criteria of energy
Produce heat, power life, or produce electricity
What is fuel
Matter that stores energy
List 4 fossil fuels
coal, petroleum, natural gas, nuclear fuel
List renewable energies
Bioenergy, hydropower, solar, geothermal
How much energy do developed countries use
20% of people use 50% of all the energy
How is methane and ethanol produced
digestion of biomass
What are hybrid tanks made out of
gas and electric
How do I figure out the kWH with watts and time
time multiplied by watts divided by 1,000
what do all nonrenewable resource power plants use heat for
produce steam to turn electric generators
Explain geothermal and its effects
Using heat stored from earth. 97% less acid rain and 99% C02
Explain conservation methods and its results
Public transport. Green building. Hybrid vehicles. Save money and health benefits
Explain biomass and its effects
Organic material being burned like wood, food, garbage, ethanol, and biodiesel. Combustion CO2, ethanol substitutes gas
Explain hydrogen fuel and its effects
High energy content per unit but more expensive. Low impacts no co2
What happened at 3 mile island
A valve was turned off realeasing radiation
What happened at chernobyl
Nuclear reaction caused radiation which blown over Europe’s
What happened at Fukushima
Earthquake tsunami which caused radiation
What are the effects of radiation
Cancer. Infant mortality rate. Plants an agriculture
Explain wind and its effects
Wind turbines collect kinetic energy. No pollution no C02 no water needed. Large scale and expensive
Explain solar and its effects
Different solar panels like photovoltaic cells. No pollutants no C02 but very expensive and takes a lot of land
Explain hydroelectric and its effects
Flow and height determined energy. Dams collect and spin turbines in rivers. No pollution but obstructs fish migration and changes temperature of water
