It is of interest to examine potential sources of greenhouse gases sources or atmospheric CO2 by analysis of the global distribution of carbon in all its forms. Atmospheric carbon, which can be assumed to be essentially all in the form of CO2 (i.e., 700 Gt carbon equals 2570 Gt of CO2) comprises only about 1.6% of total global carbon, excluding lithospheric carbon. Obvious greenhouse gases sources of direct or indirect additions of CO2 to the atmosphere are therefore fossil fuel deposits, since portions of them are combusted each year as fuels, and terrestrial biomass.

Since the early 1960s, climate change and air quality have become major and often controversial issues in many countries and among groups from governments to various scientific communities. Prominent among these issues is the greenhouse effect, in which the gradually increasing tropospheric concentrations of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N20) are believed to trap an excessive amount of solar radiation reflected from the earth.

Some forms of alternative energy sources are really new; while most of the energy forms are really come form in development and scientists have been investigated for several hundred years. One of the energy forms is biomass and bioenergy. Bioenergy refers to the burning of organic materials that would otherwise be simply discarded or not being considered at all. (more…)

Wind energy comes from the mismatched heating of the planet that runs all day and night, heated and cooled by the sun. They are also come as effect of the different between land and sea temperature, and natural barriers such as mountains. (more…)

The hydrogen can come from various sources including fossil fuels, wind, solar, biomass, nuclear, solar thermo-chemical reactions, and solar photolysis. (more…)

Natural gas is the fastest growing energy source worldwide, and its share of total energy consumption, according to the EIA, is projected to increase from 23% in 1999 to 28% in 2020. For the United States, the gas share is predicted to increase from 23.6% in 2000 to 26.5% in 2020. Gas is the cleanest of the fossil fuels, and it is the preferred choice for new electric power plants driven by gas turbines. Coal is likely to remain the lead fuel for power generation, but natural gas will expand its share considerably. (more…)

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.
