Equivalence production of solar, wind and nuclear




by Christophe » 10/06/08, 12:02

Figures found in this doc: photovoltaic technology

Quantity of energy supplied per year (8760 hours) compared to the installed power (for an industrial installation):

- 1 MW wind power supplies around 2 to 4 GWh
- 1 MW solar PV about 0,8 to 1,5 GWh
- 1 MW nuclear approximately 7 GWh


Which gives respectively load factors of:
- wind: 22.8% to 45,7%
- solar PV: 9,1% to 17,1% (ie 1,3 to 5 times less than wind)
- nuclear: 80% (without comment)


Knowing the investment costs of each energy (roughly equivalent for wind and solar and 50% more for nuclear) and when we tell you that PV is clearly not a sustainable / profitable solution, it may not be for nothing ...

long live nuclear !!!!! : Mrgreen:

of course christophe you include in your calculations the THT lines which leave from the power stations, the cost of waste management etc. : Mrgreen:

I did not say that !

I support wind, nuclear very moderately because it is not ecological, it is necessary to get rid of waste which we do not know what to do and in addition I find the power plants very ugly, so I say long live wind and long live these beautiful white ladies

wind as we do now I have a doubt ....
the infrastructure is still heavy and expensive ...
on the other hand at a lower level it would be a good thing ...

I especially think that we still precipitated a little too much wind levels. It is true that it is ecological, is beautiful (in my eyes) but too close to beautiful French coasts.

There would surely be other means like setting them up on ugly buildings from the 60s or a lot of other things and maybe a way to exploit the area much more profitable.

It is true that it almost reacted quickly but over the long term it goes, I think we should calm down and find an alternative for individuals ...

it's still normal to put wind turbines in places where there is wind : Mrgreen:

at the first gust the building collapses .... : Mrgreen:

For wind turbines it is like for the rest of renewable energies. You have to produce as close as possible to consumption.
In urban areas vertical axis wind turbines are best.
Small in size they can find their place on a building.

It would be good to have a comparison of the real price of kw taking into account the ecological aspect.
As is often indicated on this forum we would see that solar heating would be by far the most profitable.

Investment, a little more than a conventional construction
Low construction and operating ecological impact

Before trying to make electricity with the sun, if we subsidized self-construction in 2 or 3 years we could do a miracle.

however large wind turbines cannot be profitable : Mrgreen:
except to remove the subsidies, tax advantages, etc ... : Mrgreen:

with each new project, we have the right to an interview with the mayor .... "it protects the planet and it makes a big business tax : Mrgreen:
the ecological motivation is obvious : Mrgreen:

Yes it is normal but I also think that at the top of a large tower there is wind and we do not exploit it, and I do not see why the building would collapse they know very well how to do it in Holland

Back to "hydraulic, wind, geothermal, marine energy, biogas ..."
