Greening the power generation sector: Understanding the role of uncertainty

A bibliometric study of sustainable technology research

“…In addition to the articles reviewed in the areas mentioned, some recent articles on sustainable technologies, green technologies, clean technologies, renewable energy technologies and environmental technologies have also been studied, topics discussed in recent articles involves, evaluating the efficiency of such technologies using the Malmquist-Luenberger index (Feng & Wang, 2018;Luo et al, 2019;Mardani et al, 2017), examining the impact of green innovations on materials use (Wendler, 2019), exploring ways to reduce pollution and waste (Bruscato et al, 2019), toxic and organic micro-pollutants (Jankovic et al, 2019), the need to use sustainable technologies such as carbon capture in the oil and coal exploitation process to reduce pollution (Sarkodie & Ozturk, 2020), and also, the need to use low-carbon technologies to meet international climate change agreements (Romano & Fumagalli, 2018), optimizing green technologies , investigating the effects of government policies such as emission taxes on green innovation (Langinier & Ray Chaudhuri, 2019), reviewing optimal green technology innovation strategies in local governments and companies (Deng et al, 2019), investing in green technologies (Zhou et al, 2019), and R&D investments in green technology to develop these technologies (Lee et al, 2015), the amount of sustainable technologies consumed and the importance of training in adopting these technologies (Ninh et al, 2019).…”

“…Given the content of these articles, although recent articles overlap with the cited articles in the clusters under study, some of the new issues in the field of sustainable technologies have been overlooked, including issues of converting solid waste to energy (Mukherjee et al, 2020), the issue of commercialization of emerging green technologies that are essential to improving the sustainability of industrial processes (Tan et al, 2019), how to commercialize renewable energy technologies (Shakeel et al, 2017), how governments support commercialization and the drivers and barriers to commercialization (Meijer et al, 2019), and of course funding the development of new technologies as a serious obstacle to their commercialization (Tan et al, 2019), modernizing the energy sector towards the use of renewable resources and the deployment of "green technologies" that require large quantities of raw materials, some of which are at high risk for supply (Valero et al, 2018). Investigations in clusters have mentioned investment in this area, but little attention has been paid to uncertainty as one of the most important factors in investment decisions (Romano & Fumagalli, 2018).…”

The symmetric and asymmetric effects of economic policy uncertainty and oil prices on carbon emissions in the USA and China: evidence from the ARDL and non-linear ARDL approaches

“…It is noteworthy that in addition to the economic effect, EPU also has an environmental effect that is equally important (Ulucak and Khan, 2020). In theory, in times of EPU rise, the deterring impact of EPU over the adoption of green technologies results in producers adopting traditional and environmentally unfriendly production methods, which will lead to a sharp rise in energy consumption and carbon emissions accordingly (Romano and Fumagalli 2018). Meanwhile, it is difficult for enterprises to form reasonable expectations for the future.…”

Environmental taxation: The impact of carbon tax policy commitment on technology choice and social welfare

“…However, the cited works assume an unchanging tax rate, allowing firms to plan ahead. Some degree of policy uncertainty is a reality and will thus plays a role in the adoption of environmental policies by firms (Romano and Fumagalli, 2018). To consider the impact of policy uncertainty, we directly compare a commitment and no commitment carbon tax policy over multiple periods.…”

“…The literature reaffirms this assertion. In a comprehensive review of carbon policy uncertainty, Romano and Fumagalli (2018) conclude that carbon tax uncertainty often results in delayed investment in greener technologies, slowing the achievement of environmental targets. Thus, when studying the impact of environmental policies, policy commitment is an important aspect to consider.…”
