Flashcards in Chapter 13 Vocab Deck (31):
1

Biodiesel

Diesel substitute produced by extracting & chemically altering oil from plants

2

Biofuels

Liquid fuels created from processed/ refined biomass

3

Carbon neutral

An activity that does not change how much CO2 is in the atmosphere

4

Active solar energy

Energy captured from sunlight with intermediate technologies

5

Ethanol

Alcohol made by converting starches and sugars from plant material into alcohol and CO2

6

Electrolysis

Application f an electric current to water molecules to split them into hydrogen & oxygen

7

Fossil carbon

Carbon in fossil fuels

8

Flex fuel vehicles

Vehicle running on either ethanol or gasoline

9

Energy conservation

Implementation of methods to use less energy

10

Hydroelectricity

Electricity from water

11

Nonrenewable

A source that is gone once used up

12

Modern carbon

Carbon in biomass the was recent in the atmosphere

13

Nondepletable

A source that cannot be used up

14

Passive solar design

Construction designed to take advantage of solar radiation without active technology

15

Peak demand

Greatest quantity of energy used at any one time

16

Potentially renewable

Energy source that can be regenerated as long as not over harvested

17

Net removal

Process of removing more than is replaced by growth, typically used when referring to carbon

18

Smart grid

Efficient, self regulating electricity distribution network that accepts any source of electricity and distributes it effectively to users

19

Run of the river

Hydroelectricity generation in which water is retained behind a low dam or no dam

20

Renewable

Source that is either potentially renewable (renewable unless over harvested) or nondepletable (can't be used up)

21

Tiered rate system

Billing system by electric companies
User uses more their rate increases

22

Thermal inertia

Ability for a material to keep its temp.

23

Water impoundment

Storage of water in a reservoir behind a dam

24

Siltation

Accumulation of sediments, normally silt, on bottom of a reservoir

25

Tidal energy

Energy from movement of waves (gravitational pull from moon)

26

Wind energy

Energy from the kinetic energy of wind

27

Wind turbine

Turbine that converts wind energy into electrooty

28

Photovoltaic solar cells

System of capturing energy from sunlight & converting it to electricity
(Ex: Mirrors reflecting light onto pipes of liquid)

29

Ground source heat pumps

Transfers heat from ground to a building

(Ex: antifreeze pipes)

30

Geothermal energy

Heat energy that come from the radioactive decay of elements deep in earth

(Ex: geysers)

31

Fuel cell

Electrical chemical device that converts fuel (like hydrogen) into an electrical current
