Abstract.
Energy is one of the basic ingredients required to alleviate poverty and socio-economic development. The energy prospect is generally assessed on the basis of available

commercial sources of energy i.e., fossil fuel like gas, coal, oil etc. Worldwide, there is a major transition underway in the energy sector. Biogas can be a potential source of renewable energy, Residues from biogas also proven as a significant source of organic fertilizer. If there is proper policy and implementation, Bangladesh’s energy crisis and organic fertilizer demand can be control through biogas plant.

1. Introduction
By 2020, the world is throwing into turmoil as demand for energy begins to greatly exceed the supply - crippling many economies and triggering widespread social unrest. Many countries in the West may experience a decline in living standards - with oil rationing and conservation measures introduced by governments and substantial reductions in travel, tourism and aviation. The crisis plays out for nearly two decades, gradually being resolved by a switch to renewable energy and alternative fuel technologies.
In Bangladesh context, neither the decision-makers nor the experts pay due importance on proper extraction and use of renewable energy. Here grater population is using natural gas and imported oil, with the present rate of consumption, natural energy resources like gas will be exhausted shortly and this is high time to derive policy and practice for exploration and use of alternative renewable sources if we want to meet energy crisis in near future. Biogas has been found to be a proven renewable energy option.

2. Biogas
Biogas, a cheap secondary renewable energy, is a gaseous fuel obtained from biomass by the process of anaerobic digestion or fermentation. Biogas

    The Overall trend in the amount of energy use shown in Figure 1 is not dramatically changed. The amount has only increased by 20 million tonnes (in equivalent of oil) between 1970 and 2030, not much when the overall use in 2030 is expected to be a staggering 230 million tonnes. This does not indicate insecurity as such because the increase itself is not outside of our capabilities to obtain the energy. We faced an increase double that (between 2010 and 2030) in the decades between 1990 and 2010. Therefore this increase of around 9 million tonnes should not be impossible. The problems however are not with the overall figure but instead the individual energy sources within that figure and how we intend to replace our losses to meet this projection.…

    Gas production and oil are the main sources of energy. Gas fell from 9400 million cubic feet to 6600 million, it is said that gas imports will rise in the future and new techniques are being used to extract more oil, Miller oil field in Scotland is expected to extract more than £40 billion worth of new…

    At the turn of the twentieth century, the United States used coal, oil, and wood as a natural resource to produce energy. Around the beginning of the twenty-first century, those same energy resources are routine today as they were a hundred years ago. The U.S. has refined our ability to use new sources of energy that we have discovered over the last hundred years. However, “Annual consumption of petroleum and natural gas exceeded that of coal in 1947 and then quadrupled in a single generation. Neither before nor since has any source of energy become so dominant so quickly” (“Peacock”). With time the population’s need for more energy was in high demand.…

    economy as well as the downsides to renewable energy. They support fossil fuels because they create a strong economic position for the U.S. in world economy. The big oil countries rely on the U.S. as a trading partner and, according to supporters of fossil fuels, if the U.S. used renewables and rejected oil trade with those countries, “the U.S. could do irreparable damage to its place in the global energy market, and perhaps foster resentment among rival countries that had relied on the U.S. as a trading partner" ("Alternative Energy Incentives" 12). Thus, advocates are pointing out the necessary place that oil holds in the U.S. economy. That also means they view that by relying on imports, the U.S. avoids war. Oil is a big part of the fossil fuel supply. It is found in the ground after being created from age old organism remains and pressure from the earth. Other types of fossil fuels are coal and natural gas. When advocates consider the economy of oil, they note that it’s easy, cheap, and plentiful. One reason they think it is easy and cheap is because “producing energy from fossil fuels costs less today than producing equal amounts of energy from renewable sources" ("1997-98: Renewable Energy" 7). The big picture there is to produce equal amounts of energy using a renewable source and a fossil fuel is that it is cheaper using the fossil fuel. Advocates exclaim that “contrary to popular…

    While the article mainly focused on energy sources, the conclusion focused on policy implications. Notably, the fact that we will need to avoid the possible use of non-conventional fossil fuels, since these have higher than average primary/secondary energy ratios, and thus higher environmental damages, including CO2 emissions per unit of secondary energy. Secondly, the…

    Energy is the foundation of industrialized world; without energy, life as we know it would cease to exist. The yearly energy and fuel consumption rates have risen dramatically within the last years. This phenomenon is a direct result of globalization pressures, the international information network we call the Internet, and a population that seems to be hitting the dangerous upswing of the Malthusian curve. Although there is not yet a current shortage of conventional fuels, such as reserves of coal, oil and other fossil fuels are limited and non-renewable. In addition, the common practice of burning oil, coal, and other assorted hydrocarbons has resulted in hazardous environmental conditions such as global warming, acid rain and dangerously high air pollution levels. This and other environmental disasters have brought about a demand for alternative fuel and energy sources that are convenient, environmentally friendly, and economically viable. The U.S. Department of Energy defines alternative fuel as fuel that is essentially non-petroleum and yields energy security and environmental benefits. Following are some of the fuels the Department of Energy currently recognizes as alternative fuels methanol, hydrogen, liquid and compressed natural gas, and electric fuel. Alternative sources of energy are classified as energy provided from sources other than fossil fuels. This includes but is not limited to nuclear power, solar power, hydropower and biomass. Currently, many of these alternate sources are in use, but unfortunately they are underused or underdeveloped because of perceived shortcomings or drawbacks. While some of these fuel and energy sources may indeed lack the efficiency or cost effectiveness of the conventional fuel and energy, having a clean living planet far outweighs the cost of clean energy.…

    Petroleum has been a mainstay of the United State's economy for almost a century. However, oil has now been recognized as a strong catalyst for global warming, it is becoming scarce and therefore, an expensive necessity to America's economy. In the recent years many universities and scientists have looked for alternatives to oil in the form of renewable energies. These renewable energy sources would be cheaper in the long run, more efficient and environmentally clean. America as a whole must look into these new forms of renewable energy to determine if they are a practical alternative to the use of petroleum as an energy source. If we do not try to find a clean and efficient alternative to fossil fuels, I am concerned for the future of our world.…
