Television energy use was chosen for this study because it is widely used and operates together with many other associated appliances. This analysis draws from the New Zealand Television Energy Usage and Purchasing Survey to understand the current trends and patterns of television usage. The survey suggests television and associated appliance ownership and usage is increasing. Analysis draws from the survey to quantify TV energy use in New Zealand.

Over the last two decades, the residential building sector has been one of the largest energy consumption sectors in New Zealand. The relationship between that sector and household energy consumption should be carefully studied in order to optimize the energy consumption structure and satisfy energy demands. Researchers have made efforts in this field; however, few have concentrated on the association between household energy use and the cost of residential buildings. This study examined the correlation between household energy use and residential building cost. Analysis of the data indicates that they are significantly correlated. Hence, this study proposes time series methods, including the exponential smoothing method and the autoregressive integrated moving average (ARIMA) model for forecasting residential building costs of five categories of residential buildings (one-storey house, two-storey house, townhouse, residential apartment and retirement village building) in New Zealand. Moreover, the artificial neutral networks (ANNs) model was used to forecast the future usage of three types of household energy (electricity, gas and petrol) using the residential building costs. The t-test was used to validate the effectiveness of the obtained ANN models. The results indicate that the ANN models can generate acceptable forecasts. The primary contributions of this paper are twofold: (1) Identify the close correlation between household energy use and residential building costs; (2) provide a new clue for optimizing energy management.

Purpose – Although the term “energy efficiency” is technologically focused, it has a behavioural content due to the associated energy conservation practice involved. The technology aspect applies essentially to the application of new or better technology in order to derive same output or level of service for less input energy, while the conservation aspect is attributed to behaviour. The paper aims to discuss these issues. Design/methodology/approach – In an attempt to expound on this understanding, a social survey of some households in Bauchi town, Nigeria was undertaken so as to seek ways of improving the energy use situation of the country. The principal objective is to determine the influence of human behaviour in energy efficiency delivery in the households. Findings – The result reveals a much low level of energy efficiency practice by the occupants due largely to lack of awareness and requisite knowledge on the phenomenon of energy efficiency. Originality/value – Finally, the study highlights on the implications of good energy efficiency practice in household energy use as derived from the present as well as past studies in a bid to attain energy sufficiency.

Household Energy Use

Over the last two decades, residential buildings have accounted for nearly 50 percent of total energy use in New Zealand. In order to reduce household energy use, the factors that influence energy use should be continuously monitored and managed. Building researchers and professionals have made efforts to investigate the factors that affect energy use. However, few have concentrated on the association between household energy use and the cost of residential buildings. This study examined the correlation between household energy use and residential building cost. Analysis of the correlation between energy use data and residential building cost indicated that residential building cost in the construction phase and energy use in the operation stage were significantly correlated. These findings suggest that correct monitoring of building costs can help to identify trends in energy use. Therefore, this study proposes a time series model for forecasting residential building costs of five categories of residential building (one-story house, two-story house, townhouse, apartment, retirement village) in New Zealand. The primary contribution of this paper is the identification of the close correlation between household energy use and residential building costs and provide a new area for optimize energy management.

Household Energy Use

This study examined the environmental Kuznet’s curve based on the household energy use and pollution of carbon dioxide in Nigeria as a means of identifying efficient energy for a sustainable environment. Secondary data sets obtained from National Bureau of Statistics on the General Household Survey (2010-11, 2012-13, 2015-16 and 2018-19) were utilized. The study employed descriptive statistics, Consumer Lifestyle Approach and the Econometric specification for income-pollution models. The result showed that the use of diesel and kerosene were declining over the years while Liquefied Petroleum Gas (LPG), electricity and petrol recorded an increasing pattern. However, charcoal and fuelwood usage experienced some decline for the first three years of the survey and rose in 2019. The results also revealed that the total of 105674, 76329, 70006 and 47586 kg of carbon dioxide were emitted monthly based on the four data sets used respectively. With a total of 296064 and 303037 kg for rural and urban households respectively and on the average a household emits a total of 19 kg of carbon dioxide. With regards to the pollution-income relationship, the coefficients of income(y), (y2) and (y3) were all negative, although significant at 1% levels. Indicating that the Kuznets hypothesis was partially applicable to the Nigerian households, while educational level and sex were found to be negative but significant at 1% levels. On the contrary, the family size was positive and significant at 1% level but age of the household head was insignificant determinant of carbon dioxide emission. The paper recommended that the Nigeria government should improve electricity supply, LPG and the income of the households.
