Answer:
Nuclear energy is used to generate electrical power. Therefore it is only possible to reduce the emission of CO2 if nuclear power plants are used instead of other, CO2 emitting technologies. This is in particular the case for electrical generation plants fuelled by coal, oil or gas. The CO2 emission can indeed be reduced, if electrical power plants driven by fossil fuels are being replaced by nuclear power plants. However the application of nuclear power unfortunately is highly problematic, therefore the problem of CO2 emissions must not be looked at independently of all other risks and problems.
Explanation:
Now, one question can occurin the context is -
How much can nuclear energy reduce the main cause of global warming?
The International Energy Agency (IEA) records the energy consumption world-wide and produces a forecast for the next 25 years. In their last energy outlook published in autumn 2006, IEA predicts a strong increase of the carbon dioxide emissions by the year 2030 as a consequence of the increasing demand for energy world-wide.
Additionally, IEA investigated to which extent the above mentioned emissions of CO2 could be prevented if politics applied rigorous measures. One of many measures investigated was massive facilitations and incentives for building additional nuclear power plants.
From all measures proposed, nuclear energy was found to have the smallest effect (only 10%). This result is even more remarkable facing the fact that IEA is known for having no reservations whatsoever against nuclear energy.
The following results attract attention:
-
Almost 80% of the desired effects are due to increasing the energy efficiency (36% due to increasing the efficiency of the use of fossil energy, 29% due to increasing the efficiency of electrical appliances and 13% due to increasing the efficiency at the electrical power generation).
12% of the desired effects are due to furthering the generation and application of renewable energies.
Only 10% of the desired effects are due to furthering nuclear energy.
This result is surprising, in particular if you think about how nuclear power is praised as solution to global warming by politicians like George W. Bush and Tony Blair. It seems like they would (again) head into the wrong direction.
Instead of talking about measures to increase the energy efficiency, which accounts for 80% of the effects, some politicians propagandize building nuclear power plants, which according to IEA can only account for 10% of the desired effects. Here the focus is clearly on the wrong subject.
Now,one another question occurs in the context is -
Why use nuclear power at all?
If the focus is put only to avoid the emission of CO2 and if all other side effects are neglected, then nuclear energy can indeed contribute to the solution. However the problem of climate change should be solved and discussed in a much wider context: It is important to limit our consumption of resources to such an amount which does not curtail future generations nor other beings on Earth. We finally must learn to live a sustainable living .
In this context, nuclear power plants are no solution at all. On the contrary, it would mean to shift from one problem (CO2 emission) to another and not less severe problem (nuclear waste, risk of nuclear catastrophes, limited resource uranium, nuclear proliferation
Hope it helps...
