URBAN ENERGY SYSTEMS

Course Aim..

Classes: Monday (8 – 9 pm); Thursday (8 – 9 pm)

▪ Understanding of the Energy Systems that can be used for planning Cities.

▪ Conservation of these Energy Systems by means of Planning.

▪ Concepts: Sustainability, energy Consumption Patterns, Technology appraisal, Financial Viability, …

Cities: Population Density

Cities: Population Density

Urban Agglomeration..

▪ Skilled, talented labour.

▪ Higher wages, higher rate of innovation and productivity.

▪ Lower water, energy consumption (per capita)

▪ Higher levels of happiness.

Urban Agglomeration..

▪ Increased Noise.

▪ More traffic congestion, air pollution..

▪ Less nature▪ Increased

crime, drug use▪ More diseases..

Energy Consumption..

Consumption and Planning..

Eco/Green/Smart/Low Carbon City

Energy

▪ Energy is the ability to do work and work is the transfer of energy from one form to another. In practical terms, energy is what we use to manipulate the world around us, whether by exciting our muscles, by using electricity, or by using mechanical devices such as automobiles.

▪ Energy comes in various forms- heat (thermal), light (Radiant), Mechanical, Chemical, nuclear, etc.

Classification of Energy..

▪ Primary and Secondary energy.▪ Commercial and Non-Commercial

energy.▪ Renewable and Non-renewable

energy.

Urban Analytics Use of Urban Systems- Governance

Primary and Secondary Energy..

▪ Primary energy sources: found and stored in nature.

▪ Coal, oil, natural gas, biomass (wood), nuclear energy from radio active sources, thermal energy stored in earths interior, potential energy due to earths gravity, etc.

▪ Primary energy are converted into Secondary energy sources.

▪ Coal, oil, gas- is converted into steam and electricity.

Major Primary and Secondary Sources..

Commercial and Non-commercial Energy

▪ Commercial Energy: Energy sources available in the market at a definite price.

▪ Eg. Coal, lignite, oil, natural gas (refined petroleum products).

▪ Commercial energy forms the basis of industrial, agricultural, transport and commercial development.

Commercial and Non-commercial Energy

▪ Non-Commercial Energy: Sources not available in commercial market.

▪ Solar energy, animal power for transport, wind energy for lifting water, Fuels such as firewood, cattle dung, agricultural waste, which are traditionally gathered, and not bought at a price, used especially in rural households.

▪ Often ignored in energy accounting.

Renewable and Non-Renewable Energy

▪ Renewable Energy: obtained from inexhaustible sources.

▪ Can be harnessed without release of harmful pollutants.

▪ Eg. Wind power, Solar power, geothermal, Tidal, Hydro-electric, etc.

▪ Non-renewable energy is the conventional fossil fuels such as coal, oil, gas; which are likely to deplete with time.

Renewable and Non-Renewable Energy

Various forms of Energy

▪ Potential Energy▪ Chemical Energy▪ Nuclear Energy▪ Stored Mechanical Energy▪ Gravitational Energy▪ Kinetic energy▪ Radiant Energy▪ Thermal Energy▪ Electrical Energy

Grades of Energy..

▪ High Grade Energy: Chemical, Electrical- Concentrated in a small space. Molecules that store this energy are ordered and compact.

▪ Low Grade Energy: Eg. Heat, Air. Molecules are more randomly distributed and rapidly dissipated.
