Biodiversity

:
Biodiversity, the variety of life and its composition, structure and function, is closely linked to a wide range of 'ecosystem services' that sustain and fulfil human existence.
Keyword(s):

Biomass

:
Recent organic material,either plant or animal. Its stored solar energy may be converted into useful energy either by direct combustion or by first converting it into more useful forms by such processes as gasification, fermentation/distillation, anaerobic digestion or pyrolysis.

C

Climate Change

:

Is any long-term significant change in the “average weather” that a given region experiences. Average weather may include average temperature, precipitation and wind patterns. It involves changes in the variability or average state of the atmosphere over durations ranging from decades to millions of years. These changes can be caused by dynamic processes on Earth, external forces including variations in sunlight intensity, and more recently by human activities.

G

Geosequestration

:
Is a particular case of carbon Dioxide capture and sequestration (CCS). It involves the storage of CO2 in underground geological formations, such as depleted oil and gas wells, salty aquifers, and deep unminable coal seams, at depths of at least 800m.

Green Organics

:

Green organics / waste

Organic waste from parks and gardens including grass, leaves, plants, branches and twigs, tree trunks and stumps and roots.

1. Water that is found beneath the surface of the Earth.

2. Water that occurs in an aquifer; a saturated subsurface geological formation of rock and soil

Keyword(s):

P

Photovoltaic cell

:
A material that directly produces electricity when exposed to sunlight.

S

Solar thermal electricity

:
Electricity generated by using the heat from sunlight to boil water to produce steam to turn a steam turbine.

Sustainable Development

:
to meet the needs of the present, without compromising the ability of future generations to meet their own needs.
