"Alternative energy sources is designed to give the reader, a clear view of the role each form of alternative energy may play in supplying the energy needs of the human society in the near future (20-50 years).The two first chapters on "energy demand and supply" and "environmental effects," set the tone as to why alternative energy is essential for the future. The third chapter gives the laws of energy conversion processes, as well as the limitations of converting one energy form to another. The section on exergy gives a quantitative background on the capability/potential of each energy source to produce power. The fourth, fifth and sixth chapters are expositions of fission and fusion nuclear energy, the power plants that may produce power from these sources and the issues that will frame the public debate on nuclear energy. The following five chapters include descriptions of the most common renewable energy sources (wind, solar, geothermal, biomass, hydroelectric) some of the less common sources (e.g. tidal and wave energy). The emphasis of these chapters will be on the global potential of each source, the engineering/technical systems that are used in harnessing the potential of each source, the technological developments that will contribute to wider utilization of the sources and environmental effects associated with their wider use. The last three chapters are: "energy storage," which will become an important issue if renewable energy sources are used widely."

ABSTRACTInterdisciplinary in its approach and global in its perspective, Energy Systems and Sustainability: Power for a Sustainable Future, Second Edition, provides a contemporary exploration of the economic, social, environmental, and policy issues raised by current systems of energy use. Emphasizing the important issue of sustainability, it analyzes the historical evolution of the world's energy systems, the principles underlying their use, and their present status and future prospects. Beginning with a survey of basic energy concepts, the book describes the magnitude and patterns of human energy needs at various levels. It moves on to an overview of the fossil and nuclear-fuelled energy that, together with hydroelectric power and traditional biofuels, supply most of the world's commercial energy needs. Sections on economics describe the basic methods through which the monetary costs of energy are calculated, also considering the "external" costs of energy production. Finally, the book looks at the sustainability issues associated with both fossil- and nuclear-fuel use--and considers the technological advancements and social developments that might solve these problems. Providing a truly interdisciplinary approach, Energy Systems and Sustainability: Power for a Sustainable Future, Second Edition, is ideal for undergraduate engineering students and undergraduates studying policy making.

The purpose of this study is to determine the relationship between Renewable Energy Consumption (REC), Financial Development (FD), and Economic Growth (EG) by using Indonesia, the Philippines, and Malaysia as case studies. Renewable energy has been considered as an effective way to solve environmental pollution in those countries. Previous studies has shown the progress of renewable energy sector development depends on economic and financial market growth. Autoregressive Distributed Lag (ARDL) model was used to analyze the panel data between 1990-2020. The study shows that there is a negative correlation between EG and REC on short-run, but positive in the long-run. However, there is interactions between FD and REC. That governments should develop policies which increase the investment in the renewable energy sector by giving the tax relief and financial incentive. Governments should also establish and implement greener technologies for listed firms and focus to increase the use of renewable energy sources. The financial sector may facilitate firms and customers through the provision of low rate funds for the latest energy efficient technologies."

"Hampir semua mobilisasi ekonomi di negara maju maupun negara sedang berkembang didasarkan pada situasi energi fosilnya. Kekhawatiran akan perubahan iklim dan menyusutnya energi fosil, maka sumber energi terbarukan ditinjau sebagai alternatif terbaik untuk pemenuhan energi dalam pembangunan yang berkesinambungan. Teknologi energi terbarukan ditimbang memiliki peran yang menjanjikan dalam pemenuhan pembangkitan energi. Potensinya dalam pembangunan masyarakat desa di negara sedang berkembang masih kurang didemostrasikan.Di Philipina, 22 komunitas pedesaan di Mindanao, yang menggunakan 6 teknologi energi matahari dan 16 teknologi energi air diteliti dalam studi ini untuk mencari faktor-faktor yang mempengauhi kesuksesan operasi sistem energi terbarukan. Teknik lingkungan yang tidak efisien, policy umum yang buruk, keterbatasan kapasitas institusi, isyu keuangan dan ekonomi serta kondisi sosial politik ditemukan sebagai rintangan utama dalam mengadopsi teknologi energi terbarukan pedesaan. Evaluasi hukum energi di Philipina dan rencana pengembangan energi menunjukkan perlunya keterlibatan setiap level demi kesuksesan implementasi dan adopsi teknologi energi terbarukan yang juga merupakan ukuran kesuksesan mitigasi mengatasi perubahan iklim dan memastikan suplai energi yang berkesinambunngan.Dalam jangka panjang, diharapkan bahwa sistem energi terbarukan skala kecil yang dioperasikan oleh komunitas pedesaan dapat ditampung oleh jaringan listrik nasional. Hal ini akan menentukan kesuksesan atau kegagalannya. Operasinya akan terhenti bila mereka menghentikan dukungan pada sistem energi terbarukan mereka. Penampungan listrik oleh jaringan listrik nasional dapat membantu memastikan kesinambungan kerja komunitas di Mindanao."

"The analysis on manufacturing sector mostly focuses on economic valuation such as output, value added, and employment, but few studies attempt simultaneously to analyze economic, energy consumption and carbon dioxide emissions (CO2). We applied the graph theory to select the dominant industries based on selected criteria. We found that food industry became a dominant industry. However, none industry was dominant for the all criteria. This implied that pro growth is not always similar with pro environment, even the two criteria can be conflicted one and another. We argue that different characteristics of industry need to be considered in evaluating industy performance. Finally, in terms of policy intervention, we suggest government to construct intensity indicator and to develop broad policy framework in enhancing energy efficiency."
