The least - cost solar option would require 400 times more land area and emit 20 times more
CO2 than nuclear power.
Not exact matches
Take a look at
nuclear power, best safety record of any form of energy (even safer
than wind), and even in the face of
CO2 induced «climate change», they still are going to phase it out.
Nuclear power produces less greenhouse gas [
CO2]
than any other source, including coal, natural gas, hydro, solar and wind.
By the way, I'd just like to mention that I am far happier to be arguing about the comparative benefits of
nuclear power, wind, solar, geothermal, biomass, conservation, efficiency, reforestation, organic agriculture, etc. for quickly reducing
CO2 emissions and concentrations,
than to be engaged in yet another argument with someone who doesn't believe that
CO2 is a greenhouse gas, or that human activities are not causing warming, or that the Earth is cooling, or thinks that AGW is a «liberal» conspiracy to destroy capitalism, etc..
And again, my position is that (1)
nuclear power is not needed, since we can get all the electricity we need, and more, from renewables; (2)
nuclear can not possibly be expanded enough, quickly enough to have any significant impact on reducing GHG emissions in the time frame that's needed, while renewables can be (and already are); and (3) resources invested in expanding
nuclear power would be far more effectively invested in renewables and / or efficiency, and the opportunity costs of
nuclear therefore mean that putting resources into
nuclear power hinders rather
than helps the effort to quickly reduce
CO2 emissions from generating electricity.
Of the country's 6,000 coal, oil, natural gas,
nuclear, wind, and solar electric - generating facilities, a small sub-group of mostly coal - fired
power generators produces more
than its share of the nation's carbon dioxide (
CO2) emissions compared with the electricity it produces, the report found.
A new 1,000 - page Intergovernmental Panel on Climate Change report appears to ignore both
nuclear power and shale gas — even though both these energy sources emit far less
CO2 than does coal.
With
nuclear power cheaper
than fossil fuel generated electricity it could avoid 50 % of
CO2 emissions from fossil fuels by around mid 21st Century (and achieve the other objectives in the list).
According to one count, Germany's energy policy (Energiewende) to increase renewables, wean off of
nuclear power, and cut
CO2 emissions by 2022 has added more
than $ 134 billion to
power bills for Germans so far.
They'd be prepared to advocate all sorts of nutty schemes rather
than accept that
nuclear power can avoid
CO2 emissions at < $ 0 / tonne
CO2 — if we are allowed to remove the impediments that have been imposed by 50 years of irrational anti-
nuclear protests which have resulted in mass radiation phobia and hysteria.
• Kyoto Protocol • EU ETS • Australian
CO2 tax and ETS • Mandating and heavily subsidising ($ / TWh delivered) renewable energy • Masses of inappropriate regulations that have inhibited the development of
nuclear power, made it perhaps five times more expensive now
than it should be, slowed its development, slowed its roll out, caused global
CO2 emissions to be 10 % to 20 % higher now
than they would otherwise have been, meaning we are on a much slower trajectory to reduce emissions
than we would be and, most importantly, we are locked in to fossil fuel electricity generation that causes 10 to 100 times more fatalities per TWh
than would be the case if we allowed
nuclear to develop (or perhaps 1000 times according to this: http://nextbigfuture.com/2011/03/deaths-per-twh-by-energy-source.html • Making building regulations that effectively prevent people from selling, refurbishing or updating their houses if they are close to sea level (the damage to property values and to property owners» life savings is enormous as many examples in Australia are already demonstrating.
They're just saying that if you want zero -
CO2 power, then
nuclear is way more efficient
than solar or wind on an unsubsidized basis.
An electricity grid
powered b y mostly
nuclear power (like France) with some pumped hydro and some gas for peaking, abates more
CO2 than a mostly renewable energy
powered grid, and does so ant about 1/3 the abatement cost.
Anyone still banging on about
CO2 emissions in the electricity generation sector, ought to be banging on about nothing other
than nuclear power.
Nuclear power, however, emits more
than twice the total heat as its electrical output without the benefits of
CO2 in the photosynthesis cycle.
Likewise if heat is indeed the main factor,
nuclear power, though
CO2 - free, can not be an alternative since total heat emitted by
nuclear power plants is more
than twice the electrical output.
We already have a good way of massively reducing our
CO2 emissions (far more
than even banning aviation altogether would achieve)-- namely replacing coal - and gas - fired
power stations with
nuclear ones.
That's why they support AGW theory (as a pretext for carbon taxes), while opposing
nuclear power (in order to ensure that the actual effect of said carbon taxes is to raise revenue rather
than to actually reduce
CO2 emissions)?
And 5GW of newly built gas
power plants, which also emit more
CO2 than [practically zero carbon]
nuclear power plants.
Just down the road from us is Didcot A
power station, a large coal - burning plant with poor pollution control and therefore with substantial effects on local air quality, as well as more substantial emissions of radiation
than from any UK
nuclear power station and a
Co2 output of about 8 million tonnes a year.
Likewise
nuclear power produces no
CO2 but does emit more
than twice the total heat
than its electrical output.
Nuclear power is safer
than coal and when construction and operation are included it omits less
CO2 than any comparable alternative.
