Study Results

Transport greenhouse gas emissions are mainly caused by the use of fossil fuels, e.g., gasoline and diesel. This case study for The Netherlands calculates how alternative fuels, e.g., electricity, hydrogen or biofuels, contribute to policy aims to decarbonize transport. Alternative fuels, produced in various ways, have different carbon (CF), land (LFs) and water footprints (WFs). This study assesses CFs, LFs and WFs for fuels (kgCO2e/m2/m3 per GJ), showing differences among fuels dependent on primary energy sources. It calculates CFs, LFs and WFs for four scenarios with different fuels. The biofuel scenario is not attractive. CFs slightly decrease, while LFs and WFs increase enormously. The electricity scenario has small CFs and the smallest LFs and WFs, but this is only when using wind or solar energy. If storage is needed and hydrogen is produced using wind energy, CFs double from 3055 to 7074 kg CO2e, LFs increase from 15 × 106 to 43 × 106 m2 and WFs from 3 × 106 to 37 × 106 m3 compared to the electricity scenario. The case study shows that wise fuel choices contribute to policy aims to decarbonize transport, although LFs and WFs are also important to consider. These case study results are relevant for sustainable transportation transitions worldwide.

Despite China's significant progress in energy saving renovations, during the past 10 years, problems about inefficiencies remain. In the Netherlands, the energy labeling system (ELS) effectively linked policy objectives and market forces, combined with the stepped tariffs aimed at the performance of energy-saving renovation, generating a virtuous cycle of housing energy efficiency upgrading. China may draw the experience from Netherlands. In this regard, the authors probe the market effect and operating mechanism of the Dutch ELS and the stepped tariffs. The theory of multi-level governance (MLG) is introduced to the filed investigations both in China and the Netherlands. Based on the group-interviews and depth-interviews with the officials in related agencies and the residents of retrofitting housing, the authors obtained first-hand information to ensure a close case study on Netherlands' housing ELS and its implementation, in order to provide some enlightenment for China's existing housing renovation and low carbon development.

Case Study Area

Alternative sources of energy are being sought after in the world today, as the availability of fossil fuels and other non-renewable resources are declining. Solar energy offers a promising solution to this search as it is a less polluting renewable energy resource and can be easily converted into electricity through the usage of photovoltaic systems. This thesis focuses on the modeling of urban solar energy with high spatiotemporal resolution. A methodology was developed to estimate hourly solar PV electricity generation potential on rooftops in an urban environment using a 3-D model. A case study area of Ryerson University, Toronto was chosen and the incident solar radiation upon each building rooftop was calculated using a software tool called Ecotect Analysis 2011. Secondly, orthophotos of the case study area were digitized using Geographic Information Systems in order to eliminate undesirable rooftop objects within the model. Lastly, a software tool called HOMER was used to generate hourly solar PV electricity estimates using the values generated by the other two software tools as input parameters. It was found that hourly solar PV output followed the pattern of a binomial curve and that peak solar generation times coincided with summer peak electricity consumption hours in Ontario.

The Subject

SummarySubject and purpose of work: The subject of this analysis and evaluation is the use of renewable energy sources in Poland, particularly in the Lubelskie Voivodeship, as a peripheral region. The purpose of this paper is to identify the role and evaluate the scale and effects of using renewable energy sources (RES), as well as the availability and absorption of financial resources for RES promotion.Materials and methods: The data were obtained from the Office of the Ruda-Huta Commune, the Regional Operational Programme Department of the Marshal Office of the Lubelskie Voivodeship in Lublin and the Department of European Funds of the Ministry of Energy, as well as Statistics Poland (GUS) and the literature on the subject.Results: In Poland the proportion of energy from renewable sources to the total primary energy generated increased in 2012-2018 from 11.73% to 14.46%. A new phenomenon, which has been highly significant for the development of this sector, is the use of innovative, small-scale technologies of energy generation from renewable sources, which created the foundations for the growth of a citizens’ energy sector, based on the initiative of the citizens and their communities. The use of RES contributes to reduced expenditures on the purchase of energy carriers and constitutes an effective method of implementing plans for developing a low-carbon economy and reducing low-stack emissions.Conclusions: The continuing disparities between the regions point to the need for active structural intervention to maintain economic, social and territorial cohesion, particularly in areas which are considered peripheral and have a very low GDP per capita. One of the preferred directions should be to support the use of RES.

Currently one of the world’s primary energy sources, fossil fuels are also causing an increase in environmental pollution. Besides pollution, these fossil fuels are also diminishing in quantities which increase the need for alternative fuels. This rising need lead to the development of alternative renewable energy resources. A diverse range of sources are available that can be efficiently utilized to produce biofuels, in this research we utilize Tectona grandis (teak wood), Pterocarpus marsupium (malabar kino)and paper as biomass sources to produce bioethanol using Saccharomycescerevisiae fermentation. These biomasses were said to be lignocellulosic substrates rich in cellulose, hemicellulose and lignin. Simultaneous saccharification and fermentation (SSF) are used to in the conversion of substrate to ethanol in which the polysaccharides in the biomass are converted into simple sugars by hydrolysis. After which Saccharomyces cerevisiae used these basic sugars for the development of ethanol by fermentation. A bioethanol yield of 14.1%, 10.81% and 7.5% was obtained from Tectona grandis ,Pterocarpus marsupium and paper respectively, which was analyzed using dichromate titrimetric method. Thebioethanol yield from Tectona grandis is predominantly when compared with other biomasses.

The World

It is well-known that, in the past decades, the burning of fossil fuels was identified as the major cause of climate change. Climate change mitigation is becoming a central concern of global society. Limiting global warming to below 2 °C above the temperature of the pre-industrial period is the key to preserving global ecosystems and providing a secure basis for human activities, as well as reducing excessive environmental change. The ambitions increased at an accelerated pace with a dramatic expansion of net zero-emission targets. Increasing pressure from citizens and society has forced countries to intensify their climate plans, while the private sector has bought a record amount of renewable energy. An energy system based on fossil fuels must be replaced by renewable energy with low carbon emissions with improved energy efficiency. That applies to all consumers of fossil energy: cities, villages, building sectors, industry, transport, agriculture, and forestry. The paper explores and presents the strategy of energy development of renewable energy sources in the world. The application of new technologies that have led to developing renewable energy sources is presented in detail: wind energy, solar energy, small hydropower plants, biomass, and their increase in the total share of energy production, i.e., reduced fossil fuel use in energy production. Investments in new technologies used in renewable energy sources have led to increases in employment worldwide. Analysis of the trend of increased energy production from RES (Renewable Energy Sources) with investment plans, the employment rate for each energy source, and the development of renewable energy sources in the coming period are provided.

Increasing populations of about 29.24 million people in Malaysia along with rapid improvement and development results in increasing of the energy usage demands [1]. It is estimated that primary sources of energy consumption in the world is 86.4 % from fossil fuels which consists of 36.0 % from petroleum, 27.4 % from coal, 23.0 % from natural gas [2]. However, fossil fuels energy sources are non-renewable and also contribute to pollution. In order to fulfill the needs of energy used, solar light is expected to become a leading next-generation for clean and sustainable energy resources. The main interest of solar energy over other energy sources is that sunlight can be directly harvested into solar energy with the use of small and tiny photovoltaic (PV) solar cells [3].
