This project required us to be innovative and to ensure full community understanding, appreciation and ownership of technological solutions. After we conducted our first awareness-raising activities, many households were keen to light up their homes with renewable energy but often the poorest households could not afford to install the rooftop solar panels.
Renewable Electricity and Sustainability: Prospects in Developing Economies is the first book of its kind to be dedicated entirely to the needs of emerging economies. It provides readers with a comprehensive review of current renewable energy technologies, their status in emerging economies, and the potential for sustainable renewable electricity generation in those countries. A multidisciplinary approach is used to assess the needs and challenges of each region, which is supported by quantitative analyses of the current and future potential for renewable electricity generation. Real-world examples are also provided from the respective electricity sectors of each region.
Abstract:An accelerating global energy demand, paired with the harmful environmental effects of fossil fuels, has triggered the search for alternative, renewable energy sources. Biofuels are arguably a potential renewable energy source in the transportation industry as they can be used within current infrastructures and require less technological advances than other renewable alternatives, such as electric vehicles and nuclear power. The literature suggests biofuels can negatively impact food security and production; however, this is dependent on the type of feedstock used in biofuel production. Advanced biofuels, derived from inedible biomass, are heavily favoured but require further research and development to reach their full commercial potential. Replacing fossil fuels by biofuels can substantially reduce particulate matter (PM), carbon monoxide (CO) emissions, but simultaneously increase emissions of nitrogen oxides (NOx), acetaldehyde (CH3CHO) and peroxyacetyl nitrate (PAN), resulting in debates concerning the way biofuels should be implemented. The potential biofuel blends (FT-SPK, HEFA-SPK, ATJ-SPK and HFS-SIP) and their use as an alternative to kerosene-type fuels in the aviation industry have also been assessed. Although these fuels are currently more costly than conventional aviation fuels, possible reduction in production costs has been reported as a potential solution. A preliminary study shows that i-butanol emissions (1.8 Tg/year) as a biofuel can increase ozone levels by up to 6% in the upper troposphere, highlighting a potential climate impact. However, a larger number of studies will be needed to assess the practicalities and associated cost of using the biofuel in existing vehicles, particularly in terms of identifying any modifications to existing engine infrastructure, the impact of biofuel emissions, and their chemistry on the climate and human health, to fully determine their suitability as a potential renewable energy source.Keywords: biofuel; fossil fuel; climate impact; air quality; human health; aviation industry
The global community is concerned about several environmental changes. Climate change, desertification, destruction of tropical rainforests, erosion of coastal ecosystems, soil resource loss, overfishing, species extinction, and loss of biodiversity are all contributing factors. Many commentators contend that these issues make up a cumulative, sustained human impact on the environment that has profoundly changed the surface of the Earth. We explore the effects of alternative energy sources, natural resources, and government consumption expenditures on French environmental sustainability from 1990 through 2018 under the environmental Kuznets curve (EKC) framework. We apply advanced econometric methodologies for empirical analysis. Our long-run estimates indicate that alternative and nuclear energy, natural resources, and government final consumption expenditures are negatively associated with CO2 emissions, while economic growth is positively related to CO2 emissions. CO2 emissions are negatively correlated with the square root of economic growth (EKC), thereby supporting EKC. As economic growth increases, environmental sustainability deteriorates. Eventually, EKC will make a positive contribution to environmental improvement. Future research directions, research limitations, and policy implications are discussed.
Conserving energy reduces demand and lessens negative environmental impacts since most of our energy comes from non-renewable fossil fuels. Besides preserving resources, energy conservation saves money and improves the environment. The development of our energy systems has been influenced by various environmental concerns, from air quality problems to acid rain. These diverse environmental considerations influence and modify investments and other actions to provide secure, affordable energy. With the growing concern about climate change due to greenhouse gas (GHG) emissions, 60% of which are produced by the energy sector, the potential impact of climate change policies on the energy sector is increasing. Energy and environmental policies are inextricably linked, creating a pressing need to understand how to promote synergies. Addressing climate change requires investments in clean energy and removing existing high-emission assets. Path dependence and lock-in are potential consequences of long-lived infrastructure. Keeping temperatures below 2 C will require a faster transition away from these assets than natural infrastructure replacement (Zakari et al. 2022; Zakari and Khan 2021).
The Earth has numerous components, such as sunlight, the atmosphere, water, land, minerals, plants, and animals. It is possible to safeguard natural resources through natural heritage programs or by protecting them through nature reserves. Biodiversity and geo-diversity are often found in particular ecosystems (such as the rainforest in Fatu-Hiva) and are usually documented as such. Another important question addressed by this study is how natural resources might influence the sustainability of the French environment. French resources include iron ore, salt, sulfur, bauxite, zinc, uranium, arsenic, etc. Aside from that, the country also has an extensive timber and fishing industry and a considerable amount of renewable energy. A surprising thing about France is that it only has limited reserves. Large amounts of natural minerals across the country have been depleted due to heavier mining during the industrial revolution, which played a huge role in transforming France into what it is today. It is estimated that France has significant coal, iron ores, bauxite, and uranium reserves. However, they are of shallow depths and difficult to extract, making them unsuitable for steel production. It is a pity that the iron ores in this region are of low quality. The uranium ores are very rare.
Efforts to create an environment conducive to nuclear and alternative energy in France are completely ignored in current literature. This paper explores the effects of alternative energy sources, natural resources, and government consumption expenditures on French environmental sustainability from 1990 through 2018 under the environmental Kuznets curve (EKC) consideration. France has not yet studied such multiple interactions for ecological sustainability, government spending, and economic growth. The French economic records over the study period include historic recessions and financial crises, such as the financial crisis of 2009, the nuclear disaster of Fukushima in 2011, and the Eurozone crisis in 2013. Our analysis is based on fully modified least squares (FMOLS) and generalized linear model (GLM) using Newton-Raphson and Marquardt steps for the long-run estimations. Moreover, we also apply robust least square and the generalized method of moments (GMM) for robustness checking. For analyses of GMM, we use liner estimation with one weight update with Bartlett kernel Newey-west fixed weighting matrix.
Since climate change is an all-encompassing problem, carbon emissions are measured using various mathematical models and theories. Carbon dioxide emissions have been investigated using many methods in recent years. For analyzing affluence and technology through regression, three of the most discussed ideas in the literature are EKC, STIRPAT, and the Logarithmic Mean Divisia Index (LMDI). According to Sarkodie et al. (2020), a study looked at household consumption expenditure, GDP per capita, and energy efficiency in Kenya to determine the validity of the Kuznets curve theory. Rauf et al. (2018) also show that the Belt and Road economies initiative shows evidence of EKC. Using data from 1980 through 2014, Eyup Dogan and Ilhan Ozturk examined carbon dioxide emissions and real income, non-renewable energy use, and renewable energy use in the USA. Ozturk (2017) studied carbon dioxide emissions, replacement energy consumption, foreign direct investment, and fossil fuel consumption across nine Latin American nations. Using 25 OECD nations as an example, Kahia et al. (2019) analyzed gross domestic product to per capita carbon emissions and renewable and non-renewable energy use. Sarkodie et al. (2020) examine associations between climate change and human capital in China. According to the EKC hypothesis, economic development and environmental degradation have a U-shaped curve (Panayotou 1994). EKC measures environmental pressure by measuring carbon dioxide emissions. The ecological footprint was employed by Ulucak and Bilgili (2018) to measure environmental degradation. Their research identified three types of economies: low, middle, and high. The EKC hypothesis was confirmed.
In contrast, economic growth does not reverse the trend toward consumption and reduction of non-renewable resources. If pollution is reduced in one country, corrosion may be exported elsewhere, e.g., by importing coal from developing countries. Often, environmental policies focus on immediate problems while ignoring long-term issues (Stern , 2004).
