Abstract Rapid urbanization, the increasing effects of climate change, the need to reduce fossil fuels’ dependency as well as to improve cities’ resiliency are accelerating the shift towards renewable energy. Additionally, unnecessary complex roof morphologies that are often pushed by suburban divisions’ developers to make houses look more “opulent” and appealing to homebuyers, also impede the smooth integration of active solar technologies. To address this, and to respond to increasing homebuyers’ interest in renewable energy, this study looks to demonstrate how relatively minor design changes could affect the potential for solar generation and create ‘solar ready’ homes without compromising on the aesthetic of the roof morphologies in styles expected by homebuyers. It looked at six different roof morphological forms ranging from small to large houses, a common suburban house archetype in Canada. The roof configurations were remodelled to remove ‘fake dormers’, minimise ridges and valleys, etc. This process helped maximize the south, south-east, south-west, east and west facing surfaces. The results show that these changes could have a significant impact on the magnitude of solar power generation. The power output from a remodelled neighborhood at an optimized orientation exceeded the community’s electricity demand by 24%.

The Impact

Governments intervene in the energy sector using a variety of measures to pursue a range of objectives, from security of supply and energy efficiency to environmental protection. Recent concerns about the impact of fossil fuels on climate change have resulted in the increasing promotion of biofuels as an alternative to oil. While worries exist with regard to the environmental impact of biofuel production in ecologically sensitive areas, it has been argued that with an effective regulatory framework to promote sustainable production, biofuels could provide a mechanism to provide energy security in an environmentally positive way.1 The interest of the European Union (EU) in the promotion of biofuels production is a relatively recent phenomenon and it is now the world's largest producer of biodiesel and the fourth largest producer of bioethanol. At its most basic level, the promotion of biofuels as an alternative to fossil fuels is part of a wider EU effort to support the use of renewable energy. The promotion of renewable energy is traceable to a number of goals, a central one of which is ensuring security of energy supply.2 Other policy goals supported by the promotion of renewable energies include reducing greenhouse gas emissions associated with climate change, decreasing dependence upon imported oil, the promotion of technological development as well as regional and rural development and employment.3

Abstract This work presents a design for Hydrokinetic Renewable Energy (HRE), for off grid power generation for remote riverine regions in developing nations. The uniqueness of this technique for power generation using streams and other marine currents to generate electric energy is detailed. The problem of the impact of greenhouse gas emissions on the environment, rapid increase in human population, industries, modernization and our lifestyle put immense pressure on most power generation plants and infrastructures. Thus, global warming and carbon footprints of using fossil fuels to generate energy has driven the interest for energy generation from renewable sources. The Upper River Benue and Lower River Niger coastal basins, as well as the River Niger Basin on the Lower Niger sub-basin area of southeastern Nigeria was selected as a case study for the design of the hydrokinetic power generation technology. The results show that for a hydrokinetic turbine the level of power output is directly proportional to the flow velocity. Therefore the cost of its installation is reduced drastically from about $7,900 per installed kW to about $2,500 per kW, is easily assessable, less technical and a familiar motor technology for most of these communities. It is also a predictable form of energy in comparison to other emerging renewable energy fields like wind, solar and wave. Also this form of renewable energy is less harmful to the environment, has a lower noise emission and produces no greenhouse gases or any solid waste. HRE will bring energy security that is essential for the riverine dweller and curb rural urban migration and both improves the rural communities' standard of living and enhances their productivity.

The Impact

Climate change is a global scale crisis with drastic effects on higher altitudes. Ice melting and its corresponding impacts on mountain ecosystems are just some of the most directly visible signals of global warming. Increased rate of energy consumption, emissions along with ever growing tourist inflow in such areas has a high impact on this phenomenon. Particulate matter, Carbon Dioxide and Methane are some of the chief emissions in such areas with negative impact on the environment. Since burning of fossil fuels is one of the main root causes of cclimate change, its risk mitigation and adaptation depends greatly on energy conservation and the use of renewable energy technologies. Well insulated energy – efficient building construction method and the increased use of renewable energy sources could be the key solution. Reduction of dung-cakes and kerosene for space heating would decrease the greenhouse gas emissions as well as black carbons and particulate matters and improves the indoor living conditions. Energy efficient technologies including the building of traditional Sherpa houses could be the best practice to reduce the impact of climate change in high altitudes. This paper is primarily concerned with testing the thermal properties of insulating tiles made of locally available materials as well as to establish a correlation between energy consumption patterns in different building types with respective CO2 emissions.Subsequently, the positive attributes of such energy conserving design in relation to climate change adaptation is ascertained.

The Impact

The increase in global electricity demand, along with its impact on climate change, call for integrating sustainability aspects in the power system expansion planning. Sustainable power generation planning needs to fulfill different, often contradictory, objectives. This paper proposes a multi-objective optimisation model integrating four objective functions, including minimisation of total discounted costs, carbon emissions, land use, and social opposition. Other factors addressed in the model include renewable energy share, jobs created, mortality rates, and energy diversity, among others. Single-objective linear optimisations are initially performed to investigate the impact of each objective function on the resulting power generation mix. Minimising land use and discounted total costs favoured fossil fuels technologies, as opposed to minimising carbon emissions, which resulted in increased renewable energy shares. Minimising social opposition also favoured renewable energy shares, except for hydropower and onshore wind technologies. Accordingly, to investigate the trade-offs among the objective functions, Pareto front candidates for each pair of objective functions were generated, indicating a strong correlation between the minimisation of carbon emissions and the social opposition. Limited trade-offs were also observed between the minimisation of costs and land use. Integrating the objective functions in the multi-objective model resulted in various non-dominated solutions. This tool aims to enable decision-makers identify the trade-offs when optimising the power system under different objectives and determine the most suitable electricity generation mix.

The present work considers the dramatic changes the COVID-19 pandemic has brought to the global economy, with particular emphasis on energy. Focusing on the European Union, the article discusses the opportunities policy makers can implement to reduce the climate impacts and achieve the Paris Agreement 2050 targets. The analysis specifically looks at the fossil fuels industry and the future of the fossil sector post COVID-19 pandemic. The analysis first revises the fossil fuel sector, and then considers the need for a shift of the global climate change policy from promoting the deployment of renewable energy sources to curtailing the use of fossil fuels. This will be a change to the current global approach, from a relative passive one to a strategically dynamic and proactive one. Such a curtailment should be based on actual volumes of fossil fuels used and not on percentages. Finally, conclusions are preliminary applied to the European Union policies for net zero by 2050 based on a two-fold strategy: continuing and reinforcing the implementation of the Renewable Energy Directive to 2035, while adopting a new directive for fixed and over time increasing curtailment of fossils as of 2025 until 2050.

The Impact

With a growing demand for safe, clean, and affordable energy, countries across the world are now seeking to create and rapidly develop renewable energy (RE) businesses. The success of these businesses often hinges on their ability to translate RE into sustainable value for energy consumers and the multiple stakeholders in the energy industry. Such value includes low production costs due to an abundance of natural resources (e.g., wind, water, sunlight), and public health benefits from reduced environmental pollution. Despite the potential for value creation, many RE businesses have struggled to create affordable energy as abundant as that which is produced by traditional fossil fuels. The rationale being that traditional RE sources emanating from natural resources tend to rely on unpredictable weather conditions. Therefore, to help RE businesses deliver sustainable value, we should leverage disruptive innovation that is less dependent on natural resources. This paper is one of the first attempts to assess the impact of disruptive innovation on RE business performances based on the survey data obtained from multiple countries representing both emerging and developed economies.

The Future

The interest in renewable energy to replace fossil fuel is increasing as the problem caused by climate change become more severe. Small hydropower (SHP) is evaluated as a resource with high development value because of its high energy density compared to other renewable energy sources. SHP may be an attractive and sustainable power generation environmental perspective because of its potential to be found in small rivers and streams. The power generation potential could be estimated based on the discharge in the river basin. Since the river discharge depends on the climate conditions, the hydropower generation potential changes sensitively according to climate variability. Therefore, it is necessary to analyze the SHP potential in consideration of future climate change. In this study, the future prospect of SHP potential is simulated for the period of 2021 to 2100 considering the climate change in three hydropower plants of Deoksong, Hanseok, and Socheon stations, Korea. As the results, SHP potential for the near future (2021 to 2040) shows a tendency to be increased and the highest increase is 23.4% at the Deoksong SPH plant. Through the result of future prospect, we have shown that hydroelectric power generation capacity or SHP potential will be increased in the future. Therefore, we believe that it is necessary to revitalize the development of SHP in order to expand the use of renewable energy. Also, a methodology presented in this study could be used for the future prospect of the small hydropower potential.

The integration of renewable energy (RE) into the overall energy mix of Caribbean nations has been increasing in recent times. The volatile nature of the carbon-based industry through fluctuations in prices of fossil fuel based-products renders it necessary to promote an aggressive energy profile transition to renewable energy, as this is crucial to energy security in these vulnerable Small Island Developing States (SIDS). The nation of Barbados has notably understood this reality and, as such, its government has endorsed the approach of 100% RE implementation by 2030. This paper explores three distinctive annual growth rate (AGR) scenarios to assess the impact on the expected power generation, economic and environmental parameters through the period of 2019-2030. Notable findings at a high case scenario for 2030 (at an AGR of 3%) projects a power generation of 1.343 Tera-watts-hour (TWh), which will displace 790,500 barrels of oil equivalent (boe), resulting in an abatement of approximately 0.95 million tons of carbon dioxide into the atmosphere.
