Federal Excise Taxes to Motor Fuels: Gasoline, Diesel, Aviation Jet Fuel

Federal Excise Taxes
Federal Excise Taxes placed on specific energy sources tend to reduce energy demand for these energy sources in both the short and the long run. The federal government imposes excise taxes on almost all petroleum products (including petroleum additives) and coal (see Table 1). The federal government also imposes federal excise taxes on many transportation uses of methanol, ethanol, natural gas, and propane and imposes a fee on electricity produced from nuclear power plants and nuclear power electricity.

Biomass Storage and Pretreatment of Biomass Feedstock

Biomass Storage

Biomass storage is required to ensure the continuous operation of the facility. To limit the space required for storage at the plant site, biomass must be stored in relatively high piles. Two main problems associated with fuel storage are decomposition and selfheating. Self-heating increases the rate of decomposition and fire risk, and it encourages the growth of thermophilic fungi whose spores can cause a respiratory condition in humans similar to farmers lung. Some small virgin biomass losses may occur at the storage stage, but they are likely to be negligible. For intermediary storage of the fuel between the pretreatment (e.g., drying and sizing) and gasification stage, storage silos may be used. (more…)

Biomass Gasification Process Effect of Feedstock Properties and Operating Parameters

Biomass Gasification Feedstock
Thermo chemical processing of biomass yields gaseous, liquid, and solid products and offers a means of producing useful gaseous and/or liquid fuels. Biomass gasification is a total degradation process consisting of a sequence of thermal and thermo chemical processes that converts practically all the carbon in the biomass to gaseous form, leaving an inert residue. The gas produced consists of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4), and nitrogen (N2) (if air is used as the oxidizing agent) and contains impurities, such as small char particles, ash, tars, and oils. The solid residue will consist of ash (composed principally of the oxides of Ca, K, Na, Mg, and Si) and possibly carbon or char. (more…)

Energy Sources Countries Location

During the twentieth century, energy has become much more easily available. Most energy comes from burning fossil fuels (oil, gas, and coal). These resources are only found in certain geologic formations. (more…)

Fossil Fuels Research and Development

Fossil fuels, had a broader impact in current society, still oil is the one that have far reaching effect. Oil, in all its forms is the fuel that every modern means possible and draw goods and people moving around the world. After the crude oil refined products widespread use all over the world, United States, (more…)

Underground Coal Gasification Process - Discover How UCG Process Can Save You Money

coal gasification process
Anyone who wants to save money on gas should be interested in the process of underground coal gasification, or UCG. It is an alternative way of obtaining clean fuels, one that has been explored more recently due to increasing oil prices. Considering that the process benefits everyone, it is surprising how few individuals have any idea what it is. Not only do its advantages affect everyone, but the ideas and technology behind UCG are also fascinating. For this reason, it is important to at least have an idea of what goes on underground during the coal gasification process. (more…)

How Fossil Fuels Have Affected Our Environment and Lives

fossil fuels environment
In the beginning, human progress was limited by the amount of work in single day. This is only to feed themselves and their families. At that time, the economy was largely rural as a result. In the early of 19th century, more intelligent human began to looking for energy resources to support their lives. They began to develop coal, oil, and other stored energy to supplement their prime energy source: sunlight. Sunlight energy results in overgrown plant and animal growth over huge and dispersed areas and geologic time periods. There was, and will continue to be, abundant solar energy sources available to get more fossil fuel, to do research on how to exploit these resources more efficiently, and to use them in daily life and changing their cultures.
