The pollution caused by the use of fossil fuels for the production of mechanical or electrical energy is one of the most important environmental issues nowa?days. In this respect, biofuels represent a viable source of energy. Bioethanol as a renewable energy source is derived from organic material of plant origin, so-called biomass, thus reducing environmental pollution. The aim of this study was to analyze the potential of bioethanol in meeting future energy demands in the Republic of Serbia.

Abstract This is an expository study towards ascertaining the ability of Indonesia in mitigating carbon emission. Indonesia is positioned as among the best performing economies in Southeast Asia because of its vigorous fiscal management and sustained economic growth over the years. The country’s foreign investment inflow increased to 14% in 2019, largely in gas, electricity, water, and transportation because of the viability of its macroeconomic reforms. To test the environmental implication of this macroeconomic performance of Indonesia and to see its ability to achieve carbon neutrality, we adopt Indonesian quarterly data of 1990Q1- 2018Q4 for empirical analysis. Relevance Instruments in the economic performance of Indonesia such as urbanization, foreign direct investment (FDI) and renewable energy source are all adopted for accurate estimations and analysis of this topic. Different approaches such as structural break test, autoregressive distributed lag (ARDL)-bounds testing and granger causality are all adopted in this study. Our analysis and policy recommendations are based on short run and long run ARDL dynamics and granger causality. Findings from ARDL confirmed, negative relationship between carbon emission and renewable energy source, FDI and urbanization. Also, a U-shape instead of inverted U-shape EKC is found confirming the impeding implication of Indonesian economic growth to its environmental performance if not checkmate. From granger causality analysis, all the variables are seen transmitting to urbanization in a one-way causal relationship. Also, FDI and renewable energy prove to be essential determinants of the country’s environment development, hence, FDI is seen transmitting to both energy source (fossil fuels and renewables) in a one- way causal relationship. Renewable energy is as well seen having two ways causal relationship with both carbon emission and fossil fuels. This result has equally exposed the significant position of the three instruments (urbanization, FDI and renewable energy source) in Indonesia environment development.

<p>The solar energy is fast becoming a different means of electricity resource. Now in world Fossil fuels are seriously depleting thus the need for another energy source is a necessity. To create effective utilization of its solar, energy efficiency must be maximized. An attainable way to deal with amplifying the power output of sun-powered exhibit is by sun tracking. This paper presents the control system for a solar cell orientation device which follows the sun in real time during daytime.</p>

Renewable energy sources are gaining momentum in power sector mainly to address the impacts of climate change as well as the risks associated with usage of fossil fuels or nuclear energy sources. Hydropower is one of the most promising renewable energy source-based power plant that hold significant shares globally. But there are series of risks associated with hydropower project when we talk about sustainability and needs are felt to critically understand the pertaining risks as well as protocols or measures to quantify the risks. Such measure will prove to be crucial in underlining the strategic measures from planning, construction and operation phases of hydropower keeping on account of its sustainability.

The Impact

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.

This paper presnts biomass as a renewable energy source and defines the resources as well as the ways through biomass energy is converted into fuels, the technologies used for extracting the energy from biomass as well as the advantages and disadvantages that appear by using of biomass as a energy source. In addition,it is known hydrogen is an important alternative energy vector and a bridge to a sustainable way fot the energy future. Hydrogen is an energy carrier and can be obtained by different production technologies from a large variety of primary energy sources. At present, many researches are focused on getting energy from biomass, a sustainable and non-polluting way to replace fossil fuels, because the biomass can be considered as the best option with high potential, which meets energy requirements and could insure fuel supply in the future. Biomass and residual biomass can be used to produce hydrogen rich gas sustainably. Biomass pyrolysis and gasification offers an efficiency and economical route for the renewable hydrogen production and this is also discussed in the paper.

AbstractThe Renewable-Energy-Source-Act (EEG) promotes German biogas production in order to substitute fossil fuels, protect the environment and prevent climate change. In this paper we quantitatively analyse the EEG-reform in 2008. Results imply that the reform contributes to an expansion of biogas electricity generation and thus to substitution of fossil fuels. However, subsidies, land and transport emissions per unit of electricity produced increase. An alternative analysis shows that an EEG with tariffs independent from plant-types would provide the highest subsidy-efficiency, lower land requirements and higher transport emissions compared to EEG before its reformation.
