1
New cards
Nonrenewable energy sources
Energy sources that will be depleted faster than they can be replenished within one human lifetime.
2
New cards
Fossil fuels
Fuels that formed from the compression of dead biomass; require burning for energy and are not sustainable.
3
New cards
Renewable energy sources
Energy sources that can be replenished during a human’s lifetime.
4
New cards
Biofuels
Fuels derived from living organisms, such as plants, that can be used as alternatives to fossil fuels.
5
New cards
Cogeneration
The process of using leftover energy from generating electricity to heat a building, conserving energy.
6
New cards
Hubbert curve
A graph that shows the estimated peak and decline of oil production and consumption.
7
New cards
Energy return on energy investment (EROEI)
A measure of how much energy is gained for the energy invested in obtaining a resource.
8
New cards
Coal
A fossil fuel formed from the compression of peat and organic material over millions of years.
9
New cards
Natural gas
A fossil fuel created above oil reserves, often accessed through drilling and fracking.
10
New cards
Fracking
A method to extract natural gas by injecting high-pressure liquid into subterranean rocks.
11
New cards
Hydroelectric energy
Electricity generated by harnessing the kinetic energy of moving water.
12
New cards
Solar energy
Energy harnessed from the sun, can be passive or active, including photovoltaic systems.
13
New cards
Geothermal energy
Energy harnessed from the heat of the Earth's interior, can be used for heating and electricity.
14
New cards
Wind energy
Energy generated by turbines that convert wind movement into electricity.
15
New cards
Nuclear fission
The process of splitting an atomic nucleus to release energy, used in nuclear reactors.
16
New cards
Carbon neutral fuels
Fuels that do not add additional carbon dioxide to the atmosphere when burned.
17
New cards
Sustainable design
An architectural approach that minimizes resource use and energy consumption.
18
New cards
Biomass
Organic materials used as fuel; includes wood, crop residues, and animal waste.
19
New cards
Electricity generation
The process of generating electrical power from various energy sources.
20
New cards
Energy conservation
Efforts made to reduce energy consumption through various processes and technologies.
21
New cards
Petroleum
Crude oil that is refined and used to produce gasoline and other fuels.
22
New cards
Hydrogen fuel cells
Devices that convert hydrogen and oxygen into electricity, with water as the only byproduct.
