Abstrak: Gas hidrat merupakan sumber energi nonkonvesional yang kuantitasnya hampir dua kali lebih banyak apabila dibandingkan dengan energi yang bersumber dari fosil. Oleh karena itu, penulis memiliki tujuan untuk mengembangkan potensi gas hidrat tersebut dan mengindikasikan potensi persebaran serta pembentukannya di Indonesia. Metode penelitian yang digunakan yaitu studi pustaka yang bersumber dari literatur seperti jurnal, artikel, dan buku. Berdasarkan penelitian ini, potensi cadangan gas hidrat di Indonesia dapat ditemukan di wilayah perairan Indonesia terutama perairan laut dalam seperti di Cekungan Busur Muka Simeulue, Sumatera dan Selat Makassar. Selain itu, potensi tersebut juga didukung oleh adanya kegiatan tektonik yang terjadi Indonesia. Metode geofisika seismik, BSR (Bottom Stimulating Reflector) dan analisa AVO merupakan beberapa metode yang digunakan untuk mengindikasikan adanya keberadaan potensi gas hidrat di suatu daerah. Gas hidrat dapat menjadi substitusi bagi bahan bakar fosil dan berpotensi masuk tahap eksplorasi dan eksploitasi, sehingga dibutuhkan studi lanjutan agar dapat diproduksi secara komersial. Kata Kunci: bottom stimulating reflector (BSR), gas hidrat, Indonesia, laut dalam, seismik Abstract: Gas hydrate is a non-conventional energy source, which is almost twice as large as fossil energy sources.

The research article discussed the utilization of organic waste that always increases every year in line with the rate of population growth, therefore the article was prepared to review the utilization of organic waste as a form of conservation of electrical energy. The method in the research used is in the form of literature studies by collecting data from various sources or references relevant to the research conducted. The results of the literature study from several studies show that efforts to use organic waste derived from household waste, landfill waste, and organic waste in the market have the ability to be used for electrical energy sources and can be done energy conservation. The conclusion is that organic waste as an alternative to fossil fuels can be used as electrical energy, and that it can be used for energy conservation.

Concerns over the depletion of traditional fossil energy sources and the consequent greenhouse effect generated by the use of fossil fuels have increased, creating a need to search for alternative sources of clean energy. Thus, this work had the objective of portraying the potential of residues from agroenergy in the State of Tocantins for generation of Biogas. This article was developed under the principle of the exploratory study, through data surveys from the State. The agroenergy residues researched were soybean, cassava (manioc), rice, sugarcane, maize, sorghum and beans. The energy potential of the studied  residues represents 3.56% of the energy generation capacity by biomass sources. The source of highest agroenergy potential for biogas generation was maize, with an energy capacity of 498.90 MW. The use of biomass as an energy source presents itself as an interesting alternative in the survey carried throughout this work.

Since early human history and existence energy rich plants, wood and forest cellulosic material have been used for fire, light, heating, cooking and other daily activities. Fossil energy was the foundation of our modern society and industrialization since last two centuries, while exploration and exploitation of oil reserves and petrochemistry have largely shaped 20th century. Increasing concerns on environmental pollution, accelerated global warming, and global climate changes, continuing world's crude oil (fossil fuels) consumption and depletion, as well as energy security and energy crisis caused by daily burning large amounts of fossil fuels, led to the attraction, search and development of renewable, carbon-neutral, economically viable alternative energy sources, such as biofuels, slowly displacing petroleum fuels. In continuously growing human population reaching about 10 billion in 2050, various renewable energy sources are promoted and developed, to ensure rising energy demands in a world running out of fossil energy sources. Biofuels are produced from any kind of available biomass and categorized based on utilized carbon resources into first-, second- and third-generation. Nevertheless, biofuels’ future outlook is though beset by uncertainty. Hereby, various issues and concerns related to fossils and renewable biofuels are described and analyzed in present review article.

Available fossil energy sources are dubiously compatible with the goal of arresting climate change. Carbon capture and sequestration technologies currently do not work on an industrial scale, and even if they could be made to work, they will reduce the energy returned on energy invested (EROI) of fossil fuels to below acceptable levels. The EROI of nuclear fission is disputed, but most peer-reviewed work places it in the 5–14 range, making it of questionable utility. Nuclear fusion, if it works, will not be available in time. Some renewable sources—notably, various biofuels—have unacceptably low EROIs. The remaining forms of renewable energy—solar, wind, hydropower, and wave power—sport EROIs that are, at best, on the cusp of viability. There is reasonable hope for improvement in these technologies because they are, at present, immature. In the meantime, it would be ideal if we could find a way to give them an edge.

This is an important step in the transformation of European electricity generation, but only a small one compared to the planned goal of 55 % greenhouse gas reductions by 2030 and climate neutrality by 2050 in Europe. The EU countries will need huge investments in infrastructure to transport renewable energies from the locations of their generation to the locations of consumption. Furthermore, for the desired transformation of European electricity generation, both pricing and taxation of energies (and greenhouse gas emissions) need to be coordinated such that the EU remains competitive and effective incentives are set. Global data also show that the overall electricity transition is not progressing in line with climate targets. Clean power generation is not yet being built fast enough to keep pace with the rising electricity demand. Wind and solar power plants make up the bulk, but their growth has slowed in recent years. Even the temporary drop in electricity demand due to the COVID-19 pandemic is not enough to put the world on track and electricity demand will undoubtedly pick up soon, especially as the world seeks to electrify all sectors that still rely on fossil fuels. Solutions and more ambition worldwide are needed urgently. European Union The chart below shows the EU's energy sources since 2020.

Based on the use of panel data, the work establishes the relationship between the development of renewable energy sources and (1) the price of fossil energy, (2) the supply of oil and gas consumption through its own production, (3) the factor of the country's technological development and (4) the influence of non-competitive political institutions. The period of high prices for fossil energy (1999-2014) became the catalyst for changes in the structure of the energy balance, especially in Europe, with an increase in the production of renewable energy. However, the fall in prices in 2014 - to the present has led to stagnation in the production of renewable energy with a rapid increase in the use of fossil fuels. In the context of this work, the significance of the factors under study on the consumption of renewable energy sources is proved.

Along with events like global warming and environmental pollution, fossil energy exhaustion is also a big problem. When people are increasingly dependent on this material while fossil fuels are increasingly depleted. In the face of that risk, many countries around the world have been looking for new types of energy that are capable of regenerating and providing continuous energy. Renewable energy is found from the resources around people like wind, water, sunlight, ... and sea water is one of them. Sea waves and tides are two extremely large sources of renewable energy that have been discovered. According to the study, these two energy sources are capable of providing huge electricity to the world.
