Fuel cell
A fuel cell can generate an electrical current by converting the chemical energy of a
fuel directly into electrical energy. These differ from conventional electrical cells
because the active materials, such as fuel, are not within the cell but are supplied
from an outside source. Also, they do not contain an intermediate heat cycle, like
most other electrical generation sources.
Fugitive emissions
These are unintended leaks of gas from the processing, transmission, and/or
transportation of fossil fuels.

Geothermal Energy
Geothermal energy is heat within the earth. More specifically, it is the hot water or
steam that is extracted from geothermal reservoirs from the earth's crust. This can
be used for heat pumps, water heating, or even electricity generation.
Geothermal Power Plant
A geothermal power plant uses hydrothermal resources that have both water and
heat to generate electricity. These power plants require extremely high-temperature
(300 to 700 degrees Fahrenheit) hydrothermal resources that are derived either from
dry steam wells or hot water wells often in rocks. Wells can be as deep as 2 miles
into the earth's surface!
Global warming
This refers to the gradual increase in Earth's overall atmospheric temperature.
Historically, global warming occurred due to natural influences, however, in today's
society, the term is generally attributed to the effect of greenhouse gases caused by
pollutants like carbon dioxide.
Global Warming Potential (GWP)
The GWP is an index developed to compare the global warming impacts of different
gases. For example, GWPs are a measure of how much energy the emissions of 1 ton
