Fig. 1 . Matriz de generación eléctrica de EEUU en 2012
|
Se observa en la Fig. 1 una fuerte dependencia del carbón, en primer lugar y del gas natural en
segundo lugar. El concepto renovables incluye energías hidroeléctrica, geotérmica,
eólica, biomasa y solar. Resulta llamativa la baja incidencia del petróleo en
la matriz.
Cómo obtuvimos
el gráfico de la Fig.1
El gráfico circular, con los porcentajes de cada combustible, fue obtenido
usando Excel a partir de los datos extraídos
del siguiente gráfico de Statista: (http://www.statista.com/statistics/220174/total-us-electricity-net-generation-by-fuel/
)
Further information* According to the source, coal figures include anthracite, bituminous coal, subbituminous coal, lignite, waste coal, and coal synfuel. Petroleum: fuel oil, residual fuel oil, petroleum coke, jet fuel, kerosene, other petroleum, and waste oil. Natural gas: natural gas, plus a small amount of supplemental gaseous fuels. Other gases: last furnace gas, propane gas, other manufactured and waste gases derived from fossil fuels. Hydroelectric pumped storage: pumped storage facility production minus energy used for pumping.
** Renewable energy figures were added up. They include the following sources: hydroelectric conventional, biomass, geothermal, solar/PV, wind.
The values have been rounded to provide a better understanding of the statistic.
Totals may not equal sum of components due to independent rounding.
