22
Q

geothermal ehat comes from

A

radioactive decay of minerals within the earth

23
Q

base load electricity

A

minimum amount of electric power needed to be supplied to the electrical grid at any given time

24
Q

solar power

A

most abundant enrgy source in world

25
Q

how to get sunlight into electivity

A

solor photovoltaic- using semiconductors it can be transferred directly into electricity DC

Solar thermal- utilizes heat energy from sun as heating or electricity

26
Q

solar thermal tower

A

can collect light into heat

TOWER AND MIRRORS

27
Q

SOLAR PANELS ARE PART OF

A

SOLAR PHOTOVOLTAIC CELLS

28
Q

WATER ENERGY

A

HYDROPOWER

TIDAL POWER

29
Q

HYDROPOWER
define
2 types

A

conversion of electricity from flowing water to electricity

-dams and run of river

30
Q

dam

A

hydropower

large barrier controlling water flow!

31
Q

run of river hydropower

A

natural waterflow is only slightly distorted! not as much land destruction

32
Q

damn dangers

A

can be catastrophic

33
Q

is tidal power form the sun

A

yes gravitational pulls

34
Q

is wind power from the usn

A

yes because uneven heating creates uneven atmospehric pressure!!

35
Q

what is used to convert wind to electricity

A

turbine

36
Q

wind issues

A

land use
noise
bird disruptions

37
Q

biomass

A

energy from organic matter (liiving, recently living, dead)

38
Q

feedstock

A

any thing that is used as biomass inital!!!

39
Q

feedstock under goes what?

A

a process to turn it into energy!!

40
Q

what is biomass made into?

A

ethane often!

41
Q

biomass issues

A

deforestation land abuseQ!

42
Q

biofuel

A

combustible fuels crated from biomass

ethanol and biodeisl

43
Q

biodiseal and ethanol used as

A

replacement for regular oil gas

44
Q

how has global energy use increased over the years

A

exponentially

45
Q

how has population increased over the year

A

exponentially

46
Q

why is per capita energy use different from total energy use in countires

A

because not all of the population has access to the same resources

47
Q

GDP

A

The total market value of all goods and
services produced by the country in one
year

48
Q

INCREASED GDP

A

INCREASED ENERGY CONSUMPTION

49
Q

ENERGY INTENSITY

A

COMPARES a countrys gdp with its energy use

TJ/$

50
Q

Sustainable

A 
capable of being maintained at
length without interruption, weakening, or loss of
essential characteristics (such as matter and
energy)
51
Q

sustainable development

A 
the
development of industrial and
natural resources that meets the
needs of the present generation
without compromising the ability of
future generations to meet their own
needs
52
Q

3 measures of sustainability

A
