1THE ROLE AND POSSIBILITIES OF WIND ENERGY IN PRODUCTION SECTORS
Abstract:
The research report focuses on the research topic – “The role and possibilities of wind energy in
various production sector of Australia”. In many places of Australia, the role and possibilities of
wind energy in production sectors are getting highly efficient. Wind energy is never-ending,
renewable, sufficient and eco-friendly. The wind-mills, wind-blades and wind machines are the
mediums of wind energy. The enhancement of wind energy is very much essential these days as
natural calamities like global warming and environment pollution are increasing rapidly. For
clean environment and proper sustainability of the environment, renewable energy resources like
wind energy is essential. Governments of different countries are following the new trend of
transportation in different segments of Australian provinces. The increment of production of
wind energy directly or indirectly influencing mainly electric supply sector. Both the primary
and secondary research sources follow that assertion. However, it is also proved by primary data
analysis (executed by questionnaire process) that Australian government neither had taken
milestone steps nor the economical investment for wind energy production. The non-renewable
energy sources are decreasing day by day in this world. Sampled people are concerned about
wind energy sources decreasing the usage of enough amount of thermos-electricity received from
coal and petroleum. It is also found that people are not fully confirmed about the fact that in near
future, wind energy sources would absolutely replace the conventional energy sources reducing
the national gross and effective expense.

3THE ROLE AND POSSIBILITIES OF WIND ENERGY IN PRODUCTION SECTORS
Introduction:
Wind power is the least costly resource of wide-spread renewable energy that includes
producing electricity from the naturally generating power of the wind. In wind machines, wind
turbines seize wind energy within the location sweeping their blades. The wind machines
generate a power output that is proportional to the density of air and cubical power of speed of
wind. The spinning blades of air machines initiate an electrical generator that reproduces
electricity for supplying in various segments of Australia that are agriculture, industry,
household, mining, electric supply system, fishing, forestry and water supply system. In 2016,
wind farms of Australia produced 30.8% of the clean and renewable energy of Australia (Saidur
et al. 2010). The amount of energy is 4-5% of the overall electricity of the year of Australia.
A number of states and territories of Australia have recognized the investment regionally
that increases the scopes that wind energy offers. The government of Australia accomplished its
complete reverse wind auction in 2016 that would help to make most promising renewable
energy objective of 100% by 2020. Five wind farms became active in 2016 along with 44
turbines and almost 140 MW of electricity producing capacity (Wüstenhagen, Wolsink and
Bürer 2007). The recently launched additional projects on wind energy totally 79 wind farms
with a joined capacity of 4327 MW produced with the help of 2106 turbines (Ackermann and
Söder 2000). The statistics refer that Australia has taken 17th place in the world of wind power.
The research report discusses about recent scenario of the wind energy in Australia
according to the primary and secondary data analysis. SPSS-20 software has been utilised for
analysing the secondary data set. On the other hand, Ms-Excel has been used to analyse the
primary data set.
Discussion about wind energy:
A study of 2016 on the economic advantages of wind industry in Australia perceived that
for every 50 MW in capacity, a wind farm supplied the undertaken advantages:
Up to $250000 annually for farmers in rental income of land and $80000 on community
reflects each year (Hall, Ashworth and Devine-Wright 2013).
Indirect employment and job offers the construction phase of almost 160 people locally,
795 nation wise jobs and 504 state jobs.
Direct employment in wind energy employment has invested a total of $125000 in local
economy.
Straight employment of almost 48 construction workers in a province with each
employee spending almost $250000 in the local region of restaurants, shops, hotels and
other service sectors totally up to $1.2 million (Gross 2007).
To investigate the validity of secondary statistics, data analysis on the basis of both
primary and secondary data are investigated. Data analysis planning could be subdivided into
two parts that are primary and secondary data analysis. To highlight the key points of wind
energy in production sectors the data analysis has considered the quantitative and qualitative data
analysis both. Quantitative or numerical data variables depend on numerical data and qualitative
data variables are the categorical data.

4THE ROLE AND POSSIBILITIES OF WIND ENERGY IN PRODUCTION SECTORS
In this research, the researcher used the primary data gathered from target population. In
survey method with the help of questionnaire, the responses are collected from the target
population. Primary data collection technique is not costly but greater time taking. The
questionnaire consists close-ended questions only. The researcher also used the secondary data
analysis gathered from target population. The data about wind energy is collected from
“Aus.gov” website. The data source is authentic; however, the researcher is unable to produce
full assurance of the secondary data set.
Population Selection and Sample Drawing:
Most of the Australians expect the prosperity of wind power. It is therefore very much
vital for wind farm organizations for engaging in stable loyalty and satisfaction with people
dwelling in the neighbourhood of wind energy projects. The aiming population signifies defined
segment within larger population that are placed to serve as a primary data resource for the
research purpose. The population selected for data analysis is the sample of randomly chosen 50
samples. With the help of questionnaire method, 35 samples were selected for analysis as the
data should be free from missing values. The population is hance the community of Australia and
the sample has the individuals of each community. The samples are primary data in nature. The
data is created with the help of sample-drawing process. The assigned data is the representative
of sampling scheme for determining the number of physical samples according to the sampling
scheme (Tongco 2007).
Figure 1: Population and Sample
Sampling could be described as the defined norm utilised to choose individuals of the
population involved in the research. It should be precisely distinguished that how many
populations of interest are working directly. The procedures of statistical computing have
planned the samples gathered from larger populations. The larger size of the target population
has no preference but to observe a number of cases of elements within the sample for
representation of the conclusions about the population. The population frame undertaken in the
current analysis explains lots of people within target population who can take participation in the
research (Quinn and Keough 2002). Although sampling size is small as the number of
individuals from the sampling frame who would participate in the primary data gathering
method. Here, simple random sampling is undertaken that consists sample group members of

Data Description and Parameters:
Primary data is very specifically crucial in market research. Primary data is the
information that gather the purpose of the research project. An advantage of primary data is
specifically maintained in the needs of research. The data observed or gathered directly from
first-hand experience. The data is generally unbiased. However, sampling error may be present in
such types of data. The data includes primarily 50 samples and after cleaning the data for making
it free of missing values, 35 samples were selected for primary data analysis.
The data set have only three numerical variables. These are age, predicted producible
wind energy in Australia and estimated wind energy that would be proper for environment. The
numerical variables indicate – awareness about the advantages of wind energy, comparison
perception of renewable and conventional energy, popularity of wind energy and the sector that

would be most beneficial from high production of wind energy. Besides, several facts such as
validity of enough energy resource in Australia, technology of producing energy in Australia,
eagerness of government towards the upliftment of wind energy production, sufficiency of wind
energy, cleanliness of renewable energies such as wind energy and consideration of people about
the popularity of wind energy in near future.
Some of the qualitative variables are measured with the help of “Likert” scale that
indicates, 1 = “Strongly disagree”, 2 = “Disagree”, 3 = “Neutral”, 4 = “Agree” and 5 = “Strongly
agree” (Sullivan and Artino Jr 2013). Rest of the qualitative variables are measured with the help
of nominal scale, such as “yes” or “no”.

Sampling Errors:
Sampling error in a statistical analysis is arising from the unrepresentativeness of the
undertaken samples. The common five types of sampling error that could be identified in the data
analysis are-
1) Population Specification Error, 2) Sampling Frame Error, 3) Error due to Selection, 4) Errors
due to sampling by wrong questionnaire, 5) Errors due to non-response (Bendat and Piersol
2011).
The sampling errors arise due to the variability in the frequency or representativeness of
the responding samples. Mainly in three ways sampling errors could be controlled with the help
of large samples, careful sample designs and multiple contracts to assure representative response
(Silverman 2016). The greater sampling size of the sampling frame can reduce sampling error.
The larger sample size in survey-based studies prosper experimental studies. The most essential
factor is the cost effective, cost investment and cost factors.
Data Validity and Reliability:
Document Page
8THE ROLE AND POSSIBILITIES OF WIND ENERGY IN PRODUCTION SECTORS
The two terms data validity and reliability are often used interchangeably when these are
not related to the research statistics. Critics of statistics use the terms that indicate the various
properties of experimental or statistical process (Noble and Smith 2015). Reliability is the
measure of consistency that takes the equal personality test claimed. The validity is the measure
of authenticity of data used for analysis. Reliability and validity are independent of each other. It
is notable fact that a measurement may be valid but not reliable.
The concept behind reliability of any significant outcomes must be more than findings of
inherently repetition. The data set has replicability and universal approach (Drost 2011). The
statistical tools perform time critical experiment. The data set is neither manipulated nor
transformed deliberately for the purpose of data analysis. The social experiment concerns about
reliability and robustness of the data set.
Data Analysis:
Descriptive data analysis are short descriptive coefficients that condense the given data
set that can either be a representation of the whole population or a sample of the population.
Quantitative or numerical variables are summarized by descriptive or summary statistics process.
Categorical or qualitative variables are summarized by frequency tables and respective diagrams.
The descriptive analysis as well as correlation analysis are executed here.
