Abstract Within the framework of the study a case study is performed, the data provided by a Latvian textile production company on their electricity and natural gas consumption, as well as production volumes over a three-year period have been analysed. The specific indicators of electricity, natural gas and CO2 emissions have been calculated and the obtained results are shown in graphs. The correlation of specific indicators with production volumes was analysed by correlation coefficient and linear regression methods. An analysis of statistical data for the calculated specific indicators over a three-year period has been performed. The obtained results show high seasonality of natural gas consumption and close connection between electricity consumption and production volumes.

Per Capita

Previous studies conducted by Lebassi et al. (2010) and Sequera et al. (2011) have showed a strong correlation between summer temperature and electricity demand per capita trends for the past four decades for California. Decreasing summer temperature trends in low elevation coastal California sites between 1970–2010 resulted in decreasing electricity demand for the same locations. On the other hand, increasing temperature trends in high-elevation and inland California sites for the same period showed increasing electricity demand during summers. As a consequence of an increased gradient of the concurrent sea breeze potential for the same period, the authors suggested that this increased in sea breeze was responsible for the observed coastal cooling, attributing the seabreeze increase to a counter effect of global warming. The authors also reported increasing temperatures during winter throughout California for the same period, resulting in decreasing natural gas consumption. This work extends this analysis by determining spatial and temporal trends in residential electricity and natural gas consumption using 1990 to 2009 data from the California Energy Commission. Results show yearly electricity consumption per person is lower for coastal counties than inland counties. In contrast, yearly natural gas consumption per capita is decreasing for both coastal and inland counties. Additional work includes the examination of future summer axysymmetric warming and winter homogenous warming as well as their implications on energy demands into the 21st century. Results from 16 downscaled Global Circulation Models for 2 green-house gas emissions scenarios are used to forecast future average temperatures. These projections are correlated with electricity consumption during the summer and natural gas consumption during the winter. Statistical analysis of these results is provided in order to quantify uncertainty on these forecasts.

In this paper a mathematical multiple regression model has been constructed based on statistical data on natural gas consumption in the Federal Republic of Germany (FRG) as a function of temperature and population. A normal distribution of the raw data and residuals was analysed, and a regression equation with a possible economic treatment of the data was derived. Using mathematical methods, the autocorrelation of the model residuals was investigated. Based on the calculations, the importance of these indicators for gas consumption is shown. The importance of other variables, which are not yet reported in this study, is noted.

Sustainability goals imply not only economic and environmental components, but also a social one. The energy business around the world is profitable and economically viable, but it does not always bring appropriate benefits to a society. Besides, some governments, instead of protecting the interests of the population, turn a blind eye and generate injustice in relation to some parts of society in collaboration with energy companies. This paper examines one of the cases when the authorities pursue an unfair policy and contribute to the growth of inequality in society through regulating the natural gas tariffs. The paper considers a case of natural gas consumption and its unfair taxation by the Ukrainian government, which the authors called “gas tax”. A statistical analysis of this case revealed that honest middle-income taxpayers (middle class) are at the most disadvantageous position because they have to pay for utilities at the highest price. The paper also discusses a number of challenges and ethical issues related to the payment of gas tax. All these challenges should become arguments for revising the gas tax, making it less painful for the people and fair.

Energy is substantial for economic development. This study aims to unveil the causal relationship and long-term association between economic growth and energy consumption in Pakistan. The Granger-Causality test finds that; natural gas consumption, electricity consumption and coal consumption have uni-directional causal relationship with economic growth as (GC, EC and CC→GDP), however, GDP growth rate, natural gas consumption and coal consumption unilaterally Granger causes Inflation (GDP, GC and CC→CPI) and lastly coal consumption→natural gas consumption (GC), Electricity consumption (EC)→GC. The ARDL estimations delineate natural gas consumption and oil consumption having a positive and negative association with GDP growth rate may have significant long term impacts respectively on the the economic growth of Pakistan.
