(With additional increases due to
additional coal generation.)
Not exact matches
All told, utilities have canceled 14,000 megawatts of planned
coal - fired
generation and delayed an
additional 32,000 megawatts, according to the latest survey by the U.S. Department of Energy's (DOE) National Energy Technology Laboratory (NETL) in Pittsburgh.
If I understand the above calculation correctly, it would seem that, in the electricity sector, we could mostly concentrate on meeting
additional demand with efficiency and carbon neutral
generation (and avoid some of the fights associated with replacing existing
coal generation plants); but if we need to reduce emissions by 80 % by 2050, then I am not sure whether this makes sense.
By the time third world countries actually build substantial
additional electricity
generation, the world could be nearing the limits of
coal supply, especially if you factor in projected population growth and increased consumption.
California, Oregon, Washington and other states across the nation are forcing utilities to consider the
additional cost of curbing carbon dioxide emissions in proposed
coal - based
generation, due to increasing pressure to address climate change.
In emerging ASEAN,
additional capacity of
coal - fired
generation is likely to be built using both high efficiency and low efficiency of
coal - fired power plants depending on countries» environmental regulations and economic conditions.
Cheaper natural gas has pushed out older, less - efficient
coal and oil
generation; however, the region's increasing overreliance on natural gas will provide few
additional emissions benefits and increases risks of price volatility or supply disruption.
These
additional supplies have helped displace a significant amount of
coal for power
generation, leading to a reduction in U.S. energy - related greenhouse gas emissions to levels last seen in the 1990s.
And while one kWh of natural gas - fired
generation emits roughly half as much CO2 as a kWh of
coal - fired power, renewables emit no CO2 so each kWh of
additional generation delivers a bigger emission reduction punch.
In sum,
generation additions (plus removal of
coal costs) are in the order of $ 35 billion and
additional investments relate to transmission and distribution assets.
It is simply that there is not any REAL reason to worry a over non-existent, non-actual, non-possible «GREENHOUSE effect» induced «climate change», as is the «short answer»... and with the
additional «appendix» that those «alternate» sources (so often mentioned) of «electricity
generation» also only work «in opinion» and do NOT present REAL alternatives to Gas and
Coal (as of NOW).
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.
Many of the three billion people who do not have electricity would now have had it, saving many
additional fatalities per year (not included in the number I gave previously which was only for replacing
coal generation with nuclear
generation).
For example,
additional capacity beyond existing plants is only required by 2020 if power
generation growth exceeds 4 % year and
coal plants are run at utilisation rate of 45 % or less.
Other provisions in the act — such as tax incentives that encourage the adoption of energy - efficient technologies, a shift to more combined heat and power
generation, and the adoption of real - time pricing of electricity (a measure that will discourage optional electricity use during peak demand periods)-- would cut electricity demand enough to avoid building an
additional 37
coal - fired power plants.
The Unions argue that Eskom now has sufficient
generation capacity and that
additional renewables would only force
coal plants offline, with the loss of jobs.
Unless Germany brought an
additional 40 billion kWh of
generation from its older, more carbon - intensive
coal - fired power plants offline, this planned uptick in fossil fuel
generation would cause the country's overall carbon emissions to rise by as much as 14 % of the country's 2008 total carbon emissions (33 million tons of CO2), illustrated in Figure 1 below.
