What is Green Economy?
Green Economy is an
economic
model
based on sustainable
development and
knowledge of
ecological economies.
We can define green economy as based on:
Renewable energy Green buildings Sustainable
transport Water management Land management
Renewable energy
Renewable energy comes
from resources which
are continually
replenished such as
sunlight, wind, rain,
tides, waves,
geothermal heat and
waste.
Solar energy
Solar energy applies energy from the sun in the form of solar radiation to heat or to generate electricity. Solar powered electricity generation uses either photovoltaic or heat engines .
Geothermal energy
Geothermal energy is from thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter.
Wind power
Wind power is the conversion of wind energy into a useful form of energy, such as the one used with the turbines to make electrical power.
Biomasses
Biomasses are renewable energy sources, because the energy they contain comes from the sun. Biomasses function as sorts of natural batteries to store the solar energy contained in plants.
Hydropower
Energy in water can be harnessed and used. Since water is about 800 times denser than air, even a slow flowing stream of water, or moderate sea swell, can yield considerable amounts of energy.
Green buildingsA green building, also known
as green construction or
sustainable building,
refers to a structure which
uses a process that is
environmentally
responsible and
resource-efficient.
Sustainable transport
Sustainable transport refers to the broad subject of transport that is or approaches being sustainable. It includes vehicles, energy, infrastructures, roads, railways, airways, waterways, canals, pipelines, and terminals.
Water management
Water resource management
is the activity of planning,
developing, distributing and
managing the optimum use
of water resources. It is a
subset of water cycle management.
Water cycle
Land management
Land management is the process of managing the use and development (in both urban and rural settings) of land resources.
Environmental policy refers to the
commitment of an organization to the
laws, regulations, and other policy
mechanisms concerning environmental
issues and sustainability.
