Characteristics of City




CHARACTERISTICS OF A CITY TO IMPLEMENT IT
Generally all cities have an impact on in their consumption patterns in its regions and ecosystems. A sustainable city will need to have accountability and responsibility, for increasing consumption patterns. Cities need to work in responsibility by adapting a policy to reduce, recycle, and re-use consumed goods. Other kind of cities will need to control unsustainable consumption patterns. By examining the characteristics of a sustainable community, a better understanding can be reached about defining a sustainable community. Cities can be characterized by a number of different properties. These properties may change across countries and geographical regions.
The five basic elements to community include:
Affordable housing supporting pride & self-reliance;
Diversified economic development;
Life-long learning;
A self-governing, self organizing community; and
Stewardship of the environment.
Characteristics of Sustainability include:
The formulation of goals that are rooted in a respect for both the natural environment and human nature and that call for the use of technology in an appropriate way to serve both of these resources;
The placement of high values on quality of life;
Respect of the natural environment;
Infusement of technology with purpose;
Optimization of key resources;
Maintenance scale and capacity;
Adoption of a systems approach;
Support of life cycles;
Responsiveness and proactiveness;
Value for diversity; and
Preservation of heritage

Recomendations

For a country to develop this energy we recomend: 
  •  That the country have the resources to sustain a plant
  • Space to cunstruct the plant
  • Natural elements like trees and things that can be use to generate the fuel  

Usage

A country that already use this energy is Australia.


This is a picture of the Bioenergy plant in Australia.


This is the bioenergy plant of Australia.

  

Process

 Bioenergy - fuel created from materials like wood, sugarcane, corn or algae - is often touted as an environmentally friendly alternative to oil, coal and gas. But as our latest ‘Living Forests’ report makes clear, there are big potential risks too - we’ll need strong safeguards to protect people and the planet from unsustainable bioenergy expansion.
 Process:
  1.  Feedstock Sources: Homes, Businesses, Industry
  2. Receiving: Indoors With Emissions Management
  3. Wet Pre-treatment: Pulping & Contaminant Removal
  4. Anaerobic Digestion: Creates Biogas, Solids & Liquids
  5. Biogas Production: To Create Community Based Bioenergy Solids & Excess Liquids In Local Markets Automated Systems & Process Control
  6. Beneficial Use By-Products: Solids & Excess Liquids In Local Markets
  7. Operations Management: Automated Systems & Process Control

Advantages and Disadvantages of Biological Energy


ADVANTAGES

1.- Clean sustainable energy accessible to practically anyone (given the sufficient technology coverage). Since it is made from organic wastes, every home in the world can make up its own biological energy and have an endless choice of uses for that energy.

2.- Cheap energy and medium range energy ratio (25-30%). The process of decomposition of organic wastes is known especially for its work in fertilizing plants and other organisms, but not too long ago, scientists managed to convert that same energy for human purposes, and given those advances, human can now use it to produce electrical energy with a ratio of 25-30%.

3.- Opportunity to participate in the coming hydrogen economy. As many experts and economists have suggested, the energy of the future will no longer be produced from fossil fuels as today, but it will be exploited from organic matter, water and almost everything that contains hydrogen. Using biological energy, can give you the advantage of gaining participation in this market.

DISADVANTAGES

1.- The costs of labor, transportation, and storage are higher. Biological energy is of most convenience only when the mass of organic matter is high and concentrated, given that, storage of garbage is expensive specially because no economies of scale exist here at the time.
2.- The components that make bio energy may be scarce in certain places. It is very small part of the population in which biological products are super scarce, but in those areas, it is impossible to generate any energy from that energy.

3.- There isn´t a high demand on it. At the time, given the lower costs of consuming fossil fuels, most companies and governments do not demand for clean sources of energy, and this affects all types of renewable sources and clean energies.
