2. What is Green Economy? Green Economy is an economic model based on sustainable development and knowledge of ecological economies.

3. We can define green economy as based on: Renewable energy Green buildings Sustainable transport Water management Land management

4. Renewable energy Renewable energy comes from resources which are continually replenished such as sunlight, wind, rain, tides, waves, geothermal heat and waste.

6. 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.

7. 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.

8. 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.

9. 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.

10. 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.

11. Green buildings A 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.

12. 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.

13. 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.

15. Land management Land management is the process of managing the use and development (in both urban and rural settings) of land resources.

16. Environmental policy refers to the commitment of an organization to the laws, regulations, and other policy mechanisms concerning environmental issues and sustainability.
