Q

Greenhouse effect

A

any system where a barrier causes the inflow of
energy to outpace the outflow of energy, leading to a warming of the
interior. Specifically, this refers to the warming effect on Earth due to
atmospheric greenhouse gases that prevent radiant heat emitted from the
surface from escaping into space

Q

Greenhouse gases

A

atmospheric gases such as water vapor, carbon
dioxide, and other gases that absorb infrared radiation (a form of heat) that rises
from Earth’s surface

Q

Milankovitch Cycles

A

systematic patterns in the shape of Earth’s orbit, and
the tilt and direction of Earth’s rotational axis over 26,000–100,000-year cycles

Q

Hydrocarbons

A

such as oil and natural gas are made of strands of hydrogen and carbon
molecules derived from the photosynthesis of ancient microscopic organisms in oceans
and lakes.

Q

biofuels

A

which are derived from living things, for warmth, light, and
cooking

17
Q

proven reserves

A

the amount of a
resource that can be profitably accessed with current technology and prices

18
Q

Jevons paradox

A

affects gains in efficiency. Increased efficiency leads to lower
costs, which leads to new applications for the energy, thereby increasing
consumption

19
Q

hydraulic
fracturing (fracking)

A

Prepared by Horizontal drilling which can access more oil and prepares the rock

20
Q

Tar sands

A

type of loose-grained rock deposit that contains oil, which is released
through the application of steam and direct heat.

21
Q

Photovoltaic (PV) solar panels

A

use sunlight to directly produce electricity They can
be used at many scales, from phones to hundreds of acres on a solar farm

22
Q

Concentrated solar thermal (CST) plants

A

use huge mirrors to focus sunlight toward
liquid-filled pipes or a power tower that holds liquid. The heated liquid turns water to
steam, which turns generators to produce electricity

23
Q

Ethanol

A

is an alcohol produced by fermenting sugars (those in corn and sugarcane)
which is blended with gasoline

24
Q

Cogeneration

A

systems capture waste heat from
power plants and use it as an additional source of heating or cooling

25
municipal solid waste (MSW)
waste from households and businesses
26
life-cycle assessment
accounts for all the environmental impacts of all the steps involved in making and disposing of a product in a “cradle-to-grave” approach
27
Basel Convention
signed in 1989 by 121 countries to restrict transboundary movement of household and hazardous wastes from developed to developing countries. The United States has not ratified this agreement
28
Combustion
involves burning waste, which reduces its volume and provides heat but causes serious fires and air pollution
29
Incineration
uses controlled combustion with pollution controls in place. Waste volume is reduced 80-90%
30
Geologic disposal
injects or places waste in rock and other formations beneath Earth’s surface
31
Containment buildings
store hazardous waste in secured concrete structures with air-lock doors, liquid collection drains, and negative air pressure and dust-control systems. They allow constant monitoring and retrieval of waste.
32
Waste-to-energy facilities
use incineration to generate heat, which turns water into steam to heat buildings or turn a turbine to produce electricity. Landfills filter out the methane from landfill gases and burn it to produce steam or convert it into vehicle fuel
33
Primary (closed-loop) recycling
involves materials being processed into the same sort of product from which they came
34
Secondary (open-loop) recycling
converts materials into different products
35
recycling rate
describes the percentage of MSW that is recycled
36
Conspicuous consumption
designed to be seen and to project particular identities in society
37
Producer responsibility laws
e-waste require that manufacturers of products and packaging take responsibility for collection, recycling, reuse, or disposal
