CO2 Emission Reduction and Fossil Fuels Carbon

Reductions in carbon intensity, C/E, the carbon emitted per unit of energy generated, reflect the degree to which societies decarbonize their energy sources. The long-term trend has been a shift from coal to oil to natural gas––hydrocarbons with decreasing C/H ratios emitting progressively less CO2 per joule. However, the increasing use of clean low-carbon fuels is not sustainable without somehow disposing of excess carbon because it opposes the trend in the abundance of fossil fuels, with coal resources being the most abundant followed by oil and gas.

Greenhouse Gases Sources and Climate Change

climate change greenhouse gases
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.

Greenhouse Effect and Global Warming

greenhouse effect global warming
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.

Alternative Energy Forward to the Future

<br />
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…)

Taking Benefits of Wind Energy Electricity

benefits of wind energy electricity
Wind energy comes from the mismatched heating system 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 heat temperature, and natural barriers such as mountains. (more…)

Natural Gas Price Volatility- Natural Gas Supply and Demand

natural gas supply demand
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…)
