Urban developments without reducing the ability of future generation

Urban landscapes are places where the environmental and human phenomena
coexist together. Developing parts of Earth’s land surface for urban uses is
one of the most irreversible human effects on the global biosphere. It has
impact on highly productive farmland, affects energy demand, alters the
climate, modifies hydrologic and biogeochemical cycles, fragments habitats, and
reduces biodiversity. Urban landscapes covers only 3% of the Earth’s total land
surface, however, it has the biggest effect on energy consumption. With
increase in urban landscapes more energy is needed. In the next paragraphs the
effect on energy use due to urban landscapes will be discussed more in detail.

Rise
in energy consumption was mainly caused by increases in the irregularity of
urban land forms and the expansion of urban land. Several studies were made
that found significant regional differences in the impacts of urban land and patterns
on energy consumptions were identified. In these studies it was found the
relationship between urban development and energy consumption may be effective
planning towards maintaining satisfactory developments without reducing the
ability of future generation to do the same. People use electricity in their
homes every day, the electrical power was most probably generated by burning of
coal, by a nuclear reaction, or by a hydroelectric plant on a river. Coal,
nuclear, and hydro are all sources of energy. When people use energy to do
something for instance filling up a gas tank the source might be petroleum
refined from crude oil. There are two types of energy sources which are
renewable and non-renewable. Renewable energy sources are sources which can
easily be replenished for instance e
wind energy produced using wind turbines and solar energy produced by using
solar panels to take the energy coming from the sun by means of photovoltaic
cells. On the other hand non-renewable energy sources are energy sources that
cannot be easily replenished such oil and coil and are major contributors to
pollution. Both of these energy sources can be used to produce secondary energy
sources such as electricity.

Moreover
studies have discovered factors that can be used to analyse the relationship
between energy consumption and urban form, especially in terms of the impact of
urban forms is transportation and residential energy demand, and causes heat
island effects. There are some aspects of urban forms can greatly impact energy
consumption, for instance:  the size,
pattern of mixing of land uses and pattern of travel. In the context of rapid
urbanization, developing and implementing a strict policy of controlling the
rapid expansion of urban areas in certain cities is becoming increasingly
important.  The findings show that the
growth of urban land spaces is the major reason for the tremendous rise in
energy consumption during the study period. Moreover, decreasing the rate of
the economic growth process could be the most powerful method of minimizing
energy consumption and slowing global climate change.

Urban energy landscape
is a concept that assists to study urban energy through its manifestation in
visible patterns in the built environment. Urban energy landscapes reveal some
of these city-specific conditions and hence, they may provide a useful
perspective for rethinking the urban energy transition. This paper presents a logical framework to
understand urban energy landscapes, merging insights from socio-ecological
perspectives that look into the dependence of urban areas from resource flows
and socio-technical perspectives that highlight the coevolution of behaviour
and the built environment. The paper uses three qualitative case studies to show
how the framework of urban energy landscapes can be used first, to characterise
the heterogeneity of spatial patterns in terms of the organisation of urban
energy systems; and second, to understand how these spatial patterns relate to
the urban sustainability transitions. In particular, the evidence suggests that
there is a close relationship between urban energy landscapes and the
trajectories of urban change in the cities studied. The paper concludes with a
call for a global analysis of urban energy transitions, grounded on the
insights from landscape perspectives.

The more urban landscapes increase the more demand there will be for
energy. Thus more energy needs to be created and more substations are needed to
transform high voltages to low voltages that will then be transferred to our
homes. At homes people take it for granted how much energy is needed for simple
things. For instance, for people to have tap water a lot of energy is consumed.
Energy is needed for pumping and filtering the water. Waste is also a major
problem for energy consumption. The cause to such a rise the urban landscapes a
lot of energy needs to be created therefore there is also a negative rise to
pollution, causing a greenhouse gas effect and making the earth warmer due to
trapping heat coming from the sun.

Due to energy
consumption urban areas are experiences warmer temperatures caused by human
events, this is called an urban heat island  (UHI) The temperature difference
usually is greater at night than during the day, and is most apparent when winds are weak. Urban heat Island is most visible during the summer and winter. The main reason for urban heat island effect is from the changes
of land to urban landscapes.  Another cause for this effect is waste heat that
is generated by energy usage is a secondary contributor. As a population
centre grows, it is causing an expansion its area and increase to the average
temperature in that same area. The less-used term heat island refers to any
area, populated or not, which is consistently hotter than the surrounding area.
This is effect is causing Monthly rainfall to be greater downwind of cities. Increases in heat
within urban centers increases the length of growing
seasons, and decreases the occurrence of weak tornadoes. The urban heat island decreases air quality by increasing
the production of pollutants such as ozone, and decreases water quality as warmer waters flows into
area streams and put stress on their ecosystems.
