The Impact

One crucial problem faced by Indonesia is the dependence on fossil energy reaching to 93,3%, while the share of renewable energy is only 7,7%. This causes two implications. Firstly, Indonesia is at the situation of insecurity energy due to the limitation of the availability of fossil energy. Since 2004, Indonesia is net importer oil country. Secondly, the use of fossil energy creates CO2, a component of green house gases stimulating global warming and climate change. One strategy to deal with this problem is by implementing new energy system consisting of developing renewable energy and energy efficiency. This paper observes the impact of the use of fossil energy, the measures taken to deal with these problems and the issues of implementing the measures. This research relies on secondary data available at the Ministry of Energy and Mineral Resource, Ministry of Environment and Forestry specifically at by Proper Secretariat, and other relevant sources.

The Impact

The rapid development of China's economy has led to a rapid increase in energy production and use. Among them, the excessive consumption of coal in fossil energy consumption is the leading cause of air pollution in China. This paper incorporates renewable energy innovation, fossil energy consumption and air pollution into a unified analysis framework, and uses spatial measurement models to investigate the spatial effects of renewable energy green innovation and fossil energy consumption on air pollution in China, and decomposes the total impact into direct and indirect effects. influences. The empirical results show that China's air pollution, renewable energy green innovation and fossil energy consumption are extremely uneven in geographical space, generally showing the characteristics of high in the east and low in the west, and showing a strong spatial aggregation phenomenon. Fossil energy consumption will lead to increased air pollution, and the replacement of fossil fuels with clean and renewable energy is an important means of controlling pollution emissions. The direct and indirect effects of renewable energy green innovation on air pollution are significantly negative, indicating that renewable energy green innovation not only suppresses local air pollution, but also suppresses air pollution in neighboring areas. The consumption of fossil energy will significantly increase the local air pollution, and the impact on the SO2 and Dust&Smoke pollution in the adjacent area is not very obvious. It is recommended to strengthen investment in renewable energy green innovation, reduce the proportion of traditional fossil energy consumption, and pay attention to the spatial connection and spillover of renewable energy green innovation.

The Impact

Excessive consumption of traditional fossil energy has led to more serious global air pollution. This article incorporates renewable energy green innovation (REGI), fossil energy consumption (FEC), and air pollution into a unified analysis framework. Using China’s provincial panel data, a spatial measurement model was used to investigate the spatial effects of renewable energy green innovation and fossil energy consumption on air pollution in China from 2011 to 2017. The global Moran index shows that over time, the spatial correlation of air pollution has gradually weakened, while the global correlation of renewable energy green innovation and fossil energy consumption is increasing year by year. ArcGIS visualization and partial Moran index show that air pollution, renewable energy green innovation, and fossil energy consumption are extremely uneven in geographic space. The spatial distribution of air pollution, renewable energy green innovations, and fossil energy consumption are all characterized by high in the east and low in the west and they all show a strong spatial aggregation. Applying the spatial adjacency matrix to the spatial Durbin model gave the results that China’s air pollution has a significant spatial spillover effect. Replacing fossil fuels with clean renewable energy will reduce air pollutant emissions. The Environment Kuznets Curve (EKC) hypothesis has not been supported and verified in China. The partial differential method test found that the spatial spillover benefits can be decomposed into direct effects and indirect effects. The direct and indirect effects of renewable energy green innovation on air pollution are both significantly negative, indicating that green innovation of renewable energy not only inhibits local air pollution, but also inhibits air pollution in nearby areas. The consumption of fossil energy will significantly increase the local air pollution, while the impact of sulfur dioxide (SO2) and soot (DS) pollution in nearby areas is not obvious. It is recommended to increase investment in renewable energy green innovation, reduce the proportion of traditional fossil energy consumption, and pay attention to the spatial connection and overflow of renewable energy green innovation and air pollution.

The Impact

The European Union (EU) Renewable Energy Directive set a target of 20 % share of energy from the renewable sources and 10% share of renewable energy specifically in the transport sector. This has resulted in some countries looking for bio-based alternative energies which lead to the increase in demand for bio-based feedstocks such as palm and rapeseed oil (for biodiesel) and sugar cane and corn (for ethanol). One of the new elements in the palm oil market is the growing demand for this commodity as a feedstock to biodiesel production. This will also put Malaysia in a better light on the international front for taking the effort to reduce carbon emissions. In line with this, the palm oil sector in Malaysia will be able to match the New Economic Model’s (NEM) major goals of high income, sustainability and inclusiveness. This new development is affecting the dynamics of the market, in particular, the supply and demand sectors of this commodity. This paper seeks to examine the impact of biodiesel demand on the Malaysian palm oil industry. This paper proposes a structural econometric model consisting of nine structural equations and four identities. The model has been estimated by the two stage least squares method using annual data for the period 1976–2010.

The Impact

Energy is a basic human need, which continues to increase in line with the level of life. Oil fuel / fossil energy is one of the nonrenewable energy sources which has been a mainstay to meet energy needs in all sectors of activity. The lack of students' understanding of the process of the occurrence of electrical energy makes them not much to save electricity in everyday life. During this time, most students in using electrical energy do not think about the impact on environmental sustainability. The activity of disseminating new and renewable energy is an effort or step taken to reduce dependence on fossil energy and simultaneously preserve the environment. This activity is a socialization activity led by STT-PLN lecturers to provide education to the public about the importance of understanding the use of electrical energy wisely in an effort to protect the environment.

Net Energy Ratio

In the future, Indonesia is predicted to be hit by national energy crisis so that it needs to do some efforts to overcome its dependences on these fossil energy sources. One of the efforts to lower high dependency on fossil energy sources is to find renewable energy sources. Microalgae has a great potential as a renewable energy source because it has the advantages of high productivity and sustainability. Development of microalgal biomasses as a renewable energy source is however, constrained by high cost of biomass production and low value of NER (net energy ratio) comparing tothese of other biomasses, like palm oil, jatrophaand tubers. Literature study shows that the method of NER calculation on biodiesel production does not yet include environmental variables. This researchis therefore to evaluate the values of NER before and after the addition of environmental commodity variables that consist of social, environmental and land use cost. Results of NER values calculatedusing existing LCA and modification LCA method are found to be 0,62 ± 0,078 and 0,60 ± 0,075 for algal biodiesel and 4,17 ± 0,79 and 3,22 ± 0,61 for palm biodiesel. The lower value of NER value differences for algal biomass indicates that biodiesel production from algal biomass is more environmentally-friendly. In addition, it is predicted that microalgae will have a significant contribution in the green house gases (GHGs) mitigation by replacing fossil fuel in the future through its role as a biodiesel. Keywords: net energy ratio, life cycle analysis, environmental commodity, microalgae, biodieselAbstrakDi masa depan, Indonesia diperkirakan akan dilanda krisis energi nasional sehingga perlu melakukan upaya untuk mengatasi ketergantungan terhadap energi fosil tersebut. Salah satu upayauntuk menurunkan ketergantungan pada energi fosil adalah untuk menemukan sumber energi terbarukan. Mikroalga memiliki potensi besar sebagai sumber energi terbarukan karena memiliki keuntungan dari produktivitas tinggi. Pengembangan biomasa mikroalga sebagai sumber energi terbarukan terkendala oleh tingginya biaya produksi dan nilai rendah APM (rasio energi bersih) dibandingkan dengan biomasa lainnya, seperti kelapa sawit ataupun umbi-umbian. Studi literatur menunjukkan bahwa metode perhitungan APM pada produksi biodiesel belum menyertakan variabel lingkungan. Oleh karena itu penelitian ini adalah untuk mengevaluasi nilai-nilai APM sebelum dansesudah penambahan variabel komoditas lingkungan yang terdiri dari biaya sosial, lingkungan dan penggunaan lahan. Hasil nilai NER dihitung dengan menggunakan LCA yang ada dan metode LCAmodifikasi yang ditemukan 0,62 ± 0078 dan 0,60 ± 0,075 untuk biodiesel alga dan 4,17 ± 0,79 dan 3,22 ± 0,61 untuk biodiesel sawit. Nilai yang lebih rendah dari perbedaan nilai APM untuk biomassaalga menunjukkan bahwa produksi biodiesel dari biomassa alga lebih ramah lingkungan. Selain itu, diperkirakan bahwa mikroalga akan memiliki kontribusi yang signifikan dalam mitigasi gas rumahkaca (GRK) dengan mengganti bahan bakar fosil.

The Impact

Subsidies and penalties are two main regulation methods adopted by authorities to promote the development of renewable energy. Due to the possibility of subsidy fraud, it is necessary to explore effective ways to combine these two policies. In this article, subsidy and penalty policies are incorporated into a sequential game theory model to explore the impact of different regulatory mechanisms on the promotion of renewable energy from recycled resources. We take biodiesel production from used cooking oil (UCO) as an example. UCO can be converted into environmentally friendly biodiesel or mixed with fresh cooking oil, resulting in inferior cooking oil containing harmful carcinogens but with huge profits. There are two mechanisms in the sequential combination model, spot checks after subsidy and subsidy after spot checks. Under both cases, fines are imposed if fraud is found during spot checks. The amounts of subsidies and fines also need to be determined. We show that the effects of subsidies depend on the implementation of the timing. The ex-ante subsidies have no effect. When spot checks are performed first, the larger subsidies will increase the probability of producing inferior cooking oil due to lower probability of spot checks. While combined with penalties, the ex-post subsidies have a positive effect on biodiesel production, that is, there exists synergy effect of penalty and subsidy on renewable energy production. In an infinitely repeated game, the shutdown threat of a grim trigger strategy (GTS) is much easier to induce biodiesel production than the penalty threat of a tit-for-tat strategy (TFT). When penalties are large enough, TFT can achieve the same goal of legal production effectively as GTS. The sooner illegal production is observed, the lower penalties are required to induce the processor to produce legally. Compared to subsidies, penalties are more effective in encouraging processors to produce renewable energy rather than illegal products. Moreover, our simulation results suggest that higher fines or profits from legal production are more likely to stimulate renewable energy production than subsidies. Our findings enrich our knowledge of the link between government regulations and the promotion of renewable energy.
