because these new
coal plants are «super-efficient» getting more power with

less important
because of the sulphur content regulations (US power emissions), which Wyoming
Coal meets (albeit with lower thermal value).

coal, gas and oil are cheaper and therefore (
because less in need of human labour) cleaner.

less efficient than an economy run on fossil fuel energy [
coal, preferably,
because it is the least expensive power].
Because the amount of cooling necessary is much
less per unit of electricity output in NGCC plants than in
coal or nuclear plants, dry cooling systems are more economical for NGCC plants than for other thermoelectric options.
Even Obama administration officials have said gas was a «bridge fuel» to a green energy economy
because it emits
less carbon dioxide than
coal when burned for power.
This is
because wood is both
less efficient at the point of combustion and has larger processing and supply chain emissions than
coal.
The rise of shale gas has had an environmental benefit as well — greatly reduced carbon dioxide emissions,
because generating electricity by burning natural gas emits
less than half as much carbon dioxide as burning
coal.
It takes six decades between the time the decision is made to go with a particular energy generation form and the time it's end of life; committing to
coal or natural gas right now, today, is the
less economical choice, and fiscally irresponsible,
because by the time the plant is built, there will be a 50:1 ratio of cheaper solar / wind / hydro / geothermal / wave years of service committed to.
The US natural gas industry has often argued that a switch to natural gas will significantly reduce ghg emissions from the electricity sector
because natural gas emits almost 50 %
less CO2 per unit of energy produced than
coal combustion.
«The underlying energy consumption trends that resulted in these changes — mainly
because more electricity has been generated from natural gas than from other fossil fuels — have helped to lower the U.S. emissions level since 2005

coal or petroleum.»

less constant, hence a simple response pulse response exp -LRB-- t / lifetime) is applied to the anthropic time series of
coal, gas, oil and cement which have different delta13C As the isotopic signature of (CO2 natural)(t) is slowly decreasing
because plants living days or centuries ago are now rotting and degassing and as molecules entered in the ocean decades ago are now in the upwellings after a slow migration along the equal density surface from the high latitudes where those surface are surfacing at depth zero, there are common sense constraints or bounds on the possible evolution of the delta13C of the natural out - gassed CO2 molecules.
