decreasing in
use recently.
Broadly stated: if you reject a lease and take a large portion of a commodity (here
coal, but it could have been natural gas, tar sands, etc.) off the market, you
decrease the supply, increase the cost, and, over the long term,
decrease the
use of that commodity.
Carbon pricing continues to reveal itself as an effective, efficient means to lower emissions; new data shows that UK's carbon price has greatly reduced local
coal consumption, and may result in
decreasing fracked gas
use too.

coal death train» Hansen, the airborne fraction [AF] of CO2 man - made emissions has sharply
decreased post-2000, due to «a surge of fossil fuel
use, mainly
coal»!
Beyond the US, the fracking that has led to much of the US
decrease has not yet expanded rapidly, but given that the technology exists (and is getting further refined every day) the rest of the world will also enjoy reduced CO2 emissions by
using nat gas instead of
coal.
The EIA says this is «because of the
decreased use of
coal and the increased
use of natural gas for electricity generation.»
Generating energy
using coal, oil, and gas also comes at high environmental costs by
decreasing air quality, impacting our water resources, and negatively affecting our health.
While US emissions are
decreasing slightly — both as a result of the administration's policies on renewable energy and vehicle fuel economy standards and because of sharply lower natural gas prices that have reduced
coal use for electricity generation — it is unlikely that without additional regulation or legislation that the US will meet its 2020 target.
If heat from burning the
coal is
used to «boil off» the water, there is a corresponding
decrease in the efficiency of the power station.
But in the US this
decrease occurred not through government intervention but through market - based substitution of natural gas - fired plants for
coal plants because of increased
use of fracking and other new techniques in finding additional natural gas.
The significant
decrease in
coal used to produce electricity can be attributed to three factors: overall lower electricity demand; a fuel shift to natural gas; and an offset created by more wind power production, according to Simon.
From 2010 to 2011, CO2 emissions from fossil fuel combustion
decreased by 2.5 % due to: (1) a
decrease in
coal consumption, with increased natural gas consumption and a significant increase in hydropower
used; (2) a
decrease in transportation - related energy consumption due to higher fuel costs, improvements in fuel efficiency, and a reduction in miles travelled; and (3) relatively mild winter conditions resulting in an overall
decrease in energy demand in most sectors.
