The Formation of Fossil Fuels - acaedu.net
www.acaedu.netWithout fossil fuels, most people could not drive their cars. They could not turn on their lights or heat their homes. This is because most of the energy needed to do these things comes from fossil fuels. The energy in fossil fuels originally came from the Sun. Plants use the energy in sunlight to make their own food.

www.nrc.govglobal carbon cycle. Also, ifnot used for electricity generation, the biomass would have decayed, thus emitting an equivalent amount of carbon dioxide to the atmosphere. In contrast, coal and other fossil fuels contain carbon that has been"locked-up"for millions ofyears. Therefore, when fossil fuels are used to generate electric power,
Nuclear Power in a Clean Energy System
iea.blob.core.windows.netsystems clean is to turn the electricity sector from the largest producer of CO 2 emissions into a low-carbon source that reduces fossil fuel emissions in areas like transport, heating and industry. While renewables are expected to continue to lead, nuclear power can also play an important part along with fossil fuels
The Carbon Cycle and Atmospheric Carbon Dioxide
www.ipcc.chThe present atmospheric CO 2 increase is caused by anthro-pogenic emissions of CO 2. About three-quarters of these emissions are due to fossil fuel burning. Fossil fuel burning (plus a small contribution from cement production) released on average 5.4 ± 0.3 PgC/yr during 1980 to 1989, and 6.3 ± 0.4 PgC/yr during 1990 to 1999.
