The influence of biomass energy consumption on CO2 emissions: a wavelet coherence approach

Abstract

In terms of today, one may argue, throughout observations from energy literature papers, that (i) one of the main contributors of the global warming is carbon dioxide emissions, (ii) the fossil fuel energy usage greatly contributes to the carbon dioxide emissions, and (iii) the simulations from energy models attract the attention of policy makers to renewable energy as alternative energy source to mitigate the carbon dioxide emissions. Although there appears to be intensive renewable energy works in the related literature regarding renewables' efficiency/impact on environmental quality, a researcher might still need to follow further studies to review the significance of renewables in the environment since (i) the existing seminal papers employ time series models and/or panel data models or some other statistical observation to detect the role of renewables in the environment and (ii) existing papers consider mostly aggregated renewable energy source rather than examining the major component(s) of aggregated renewables. This paper attempted to examine clearly the impact of biomass on carbon dioxide emissions in detail through time series and frequency analyses. Hence, the paper follows wavelet coherence analyses. The data covers the US monthly observations ranging from 1984:1 to 2015 for the variables of total energy carbon dioxide emissions, biomass energy consumption, coal consumption, petroleum consumption, and natural gas consumption. The paper thus, throughout wavelet coherence and wavelet partial coherence analyses, observes frequency properties as well as time series properties of relevant variables to reveal the possible significant influence of biomass usage on the emissions in the USA in both the short-term and the long-term cycles. The paper also reveals, finally, that the biomass consumption mitigates CO2 emissions in the long run cycles after the year 2005 in the USA.

Bounds testing approach to analyzing the environment Kuznets curve hypothesis with structural beaks: The role of biomass energy consumption in the United States

“…For instance, we observe that a 1% increase in biomass energy consumption will decrease emissions by 0.25-0.31%. This evidence is similar to that found by Bilgili et al (2016) and Bilgili (2016) for the US economy.…”

“…The empirical evidence indicates that the use of biomass energy is environment-friendly, but on the other hand fossil fuel consumption adds to carbon emissions. Bilgili et al (2016) apply the wavelet coherence approach to investigate the impact of biomass energy consumption on CO 2 emissions, and their empirical results show that biomass energy consumption improves environmental quality by lowering carbon emissions after 2005. Using a trivariate model, Bilgili (2016) validates that biomass energy consumption reduces carbon emissions but fossil fuels consumption increases it.…”

“…We have transformed all the variables into the log-form after converting all the series into per capita unit following Ahmed et al (2015) and others. Katircioglu (2015), Bilgili (2016) and Bilgili et al (2016) (Chai et al 2016). …”

Nexus between trade, CO2 emissions, renewable energy, and health expenditure in Pakistan

“…1 The shift from greenhouse gases and polluting technologies to RE options (ie, solar, wind, and geothermal) can considerably reduce the emissions of dangerous gases and can help in improving climate change and environmental quality. [2][3][4] RE can reduce polluted air and enhance environmental quality by reducing CO 2 emissions. 5,6 Additionally, CO 2 emissions affect the health quality of residents, which can be improved through the use of RE consumption in the industrial complex.…”

Emission Factors and Energy Properties of Agro and Forest Biomass in Aspect of Sustainability of Energy Sector

“…The consumption of such fuel pollutes the environment to a lesser extent, thus contributing to the goals of a low-emission economy [6,16]. This approach contributes to achieving sustainable economic growth through the introduction of an energy policy that reduces dependence on fossil resources and minimises environmental damage [17]. The production of biofuels, in comparison with the use of conventional energy carriers based on minerals, is really beneficial for environmental, economic and energy security reasons [18].…”
