Rudd is hoping to replace Britain's current
coal electricity output with a mix of new nuclear and natural gas - fired power plants, with less emphasis placed on renewable energy.
Not exact matches
And on unusually sunny and windy days — such as on 8 May, when for about 4 hours wind and solar power generated more than 90 % of the
electricity that Germany consumed — they must swiftly order
coal and gas - fired power stations to reduce their
output lest an influx of power «congests» the grid and increases the risk of failures.
Build before Memory Runs Out Although individual consumer actions can help, major changes in carbon
output will likely require better
electricity - generation technologies, retiring much of the
coal - fired capacity and replacing it with the most cost - effective combination of modern reactors, renewables and even clean
coal.
For example, a study by Vasilis Fthenakis and Hung Chul Kim of Columbia University (2009) found that, on a life - cycle
electricity -
output basis — including direct and indirect land transformation — utility - scale PV in the U.S. Southwest requires less land than the average U.S. power plant using surface - mined
coal.
Switching from
coal to nuclear is a 97 % reduction in
electricity's 40 % of our CO2
output.
Emissions of the main human - generated greenhouse gas are surely tracking the reversal in
electricity output, given that the vast majority of the country's
electricity comes from burning
coal.
In September,
coal - fired
electricity output and steel production, together representing about 75 percent of overall
coal consumption, declined by 0.5 percent and 1.4 percent, respectively, and further dropped by 2.8 percent and 1.3 percent in October.
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.
A dry cooling unit in a NGCC plant can only be one third the size of a dry cooling unit for a
coal or nuclear plant with the same
electricity output.
This is a continuation of the slide that
coal has been on in the United States for the last decade, with the
output of
electricity from
coal - fired plants falling 39 % from its 2007 peak to 2016.
For example, a 2009 UCS analysis found that a 25 percent by 2025 national renewable
electricity standard would lower power plant CO2 emissions 277 million metric tons annually by 2025 — the equivalent of the annual
output from 70 typical (600 MW) new
coal plants [4].
JAKARTA — Indonesia, the world's fifth - biggest carbon emitter, has significantly scaled back its
electricity output plans to boost the share of renewables, but will remain heavily reliant on
coal.
The take up rate would stop the natural increase in
electricity generation required for increasing numbers of dwellings and in several years their would be a decline in
electricity output from the
coal fired power stations to equal or match that required by industry and commerce.
The main reason was that growth in renewables and nuclear power could not keep up with increased
electricity demand, even though some sources have cited a drought - induced drop in hydropower
output as a factor in the rebounding
coal consumption.
This American study details just why increasing wind power capacity — and trying to incorporate its wildly fluctuating
output into a
coal and gas fired grid — results in increased CO2 emissions across the
electricity sector.
Baseload plants such as
coal and nuclear are hit particularly hard by reduced wholesale
electricity prices as they have low fuel costs and so don't save much money by shutting down or reducing
output on sunny days.
Brammo's Enertia e-bike has a much smaller carbon
output than other vehicles, even considering the
coal burned to produce
electricity to charge it.
«Tuning» the combustion
output of the boilers causes little loss in total efficiency, implying that the biomass - to -
electricity combustion efficiency is close to the 33 — 37 % range of an unmodified
coal plant, an efficiency that stand - alone biomass generating capacity has yet to demonstrate.

Coal says that capturing and storing CO2 from these new coal plants is a slam - dunk technology — but one that's not quite ready for prime time yet (capturing CO2 from existing combustion coal plants, while possible, is expensive and cuts the electricity output of the plant by as much as 30 perce
