1. What is sustainable energy? 2. How do we currently use energy in Georgia? 3. Which types of fossil fuels could / should we us
devlian [24]

1. Sustainable energy is the one that meets the needs of the present without compromising the possibility of future generations to meet their own needs for energy. This is actually an effective way of producing energy that has a little harmful effect on the environment. 

There are three conditions that some energy must satisfy in order to belong to the group: 

- ecologically: clean, renewable

- social: available for everyone  

- economic: provides at least the minimum profit

Sustainable energy includes the use of renewable energy sources such as hydropower, wind energy, solar energy, wave energy, geothermal energy, biomass energy.


2. In Georgia, the most of energy consumes transportation and industrial production is the second energy consumer in the country. There are many industrial plants that consume a lot of energy such as food and beverages, tobacco, chemical, plastics, wood, machinery and metal industry. Energy consumption by the population is almost identical to the consumption by industry.



3. We should use less coal and petroleum because they are the largest source of greenhouse gas emissions, like CO2 from fossil fuel combustion. Combustion of fossil fuels also produces other air pollutants, such as nitrogen oxides, sulfur dioxide, volatile organic compounds and heavy metals which damage our environment.


4. We should use more solar energy, wind energy, and geothermal energy. These sources of energy are inexhaustible and free, and the most important characteristic of the resources is that they do not pollute the environment. Also, it is a better choice to build own renewable energy facilities than import costly fuels.


5. In my area, I would propose next renewable energy sources: biomass, wind and solar power. Here, there is a flat land and during the year we have a lot of sunny and windy days. There is huge potential for producing the kinds of energy and it would be economically rentable. Also, it is a forest area with the great amount of biomass, which could collect and use for energy production instead of rotting on the ground.


6. We could do a lot of things to decrease energy consumption, starting from simple things like turning off the lights, using energy efficient light options (LED bulbs), unplugging electronics which use standby power, choosing energy-efficient items, better insulation of houses etc. Also, we could less drive own cars and use more public transport or ride bicycles.

Homeostasis is the property of living organisms in which internal systems are kept in balance. Plants stay cool in the desert heat through their reflective surfaces, reduced leaves, or leaves that are parallel to the sun.
