Estimates of fossil-fuel CO2 emissions are needed to address a variety of climate-change mitigation concerns over a broad range of spatial and temporal scales. We compared two data sets that report power-plant CO2 emissions in the conterminous U.S. for 2004, the most recent year reported in both data sets. The data sets were obtained from the Department of Energy's Energy Information Administra...

A novel fossil fuel pollution indicator based on the 13C/12C isotopic composition of plants has been designed. This bioindicator is a promising tool for future mapping of the sequestration of fossil fuel CO2 into urban vegetation. Theoretically, plants growing in fossil-fuel-CO2-contaminated areas, such as major cities, industrial centers, and highway borders, should assimilate a mixture of glo...

About this lab The natural environment involves nuclear radiation. Mankind has added to this by production of power and by application of “artificial” radiation to medical and other uses. After a hiatus of decades in the United States (but not in the rest of the world) nuclear fission power plant construction may experience a revival, under the economic pressure of fossil fuel price increases a...

the growth of the electrical energy consumption form one side and the bounded available fossil fuel and other limitations from the other side, makes the thermal power plants upgrading as a main demand in the world. decreasing the internal energy consumption, increasing the performance and the output power with the minimum costs are the important targets of the power plants retrofitting. nowaday...

Radiocarbon samples taken over Mexico City and the surrounding region during the MILAGRO field campaign in March 2006 exhibited an unexpected distribution: (1) relatively few samples (23%) were below the North American free tropospheric background value (57±2‰) despite the fossil fuel emissions from one of the world’s most highly polluted environments; and (2) frequent enrichment well above the...

Microalgae mass cultures can use solar energy for the biofixation of power plant flue gas and other concentrated CO2 sources into biomass that can be used to produce renewable fuels such as methane, ethanol, biodiesel, oils and hydrogen and for other fossil-fuel sparing products and processes. They thus can mitigate emissions of fossil CO2 and other greenhouse gases. Microalgae are currently us...

Current trends in energy production suggest that renewable energy will play an important role in future electricity generation. Among renewable sources, solar power is considered to be one of the most promising alternatives which is well supported by the rapid increase of Solar Thermal Power Plant installations worldwide. Solar energy (so as renewables) however is plagued by the intermittent na...

introduction despite the abundant renewable energy sources, the iranian energy sector relies almost entirely on fossil fuel energy resources. power sector is dominant source of co2emissions and responsible for about 35% of total co2 emissions in the country. additionally, long-term electricity demand of iran is expected to grow quickly, which in turn requires extensive investment to meet the gr...

Electricity is one of the most vital ingredients of socio-economic development of a developing country like Bangladesh. Sufficient supply of electricity is essential for attracting both domestic and foreign investment. Bangladesh electricity generation is heavily dependent on fossil fuel mostly natural gas. Due to lack of gas supply to the power plants, the Bangladesh government has ordered par...
