Wind power: for or against the wind?

Renewable energies except solar electric or thermal (seeforums dedicated below): wind turbines, energy from the sea, hydraulic and hydroelectricity, biomass, biogas, deep geothermal energy ...

Last year, wind power provided 15% of UK power, twice as much as coal, but this year, these numbers dropped to less than 2% on June 2.
At the same time, comparing an annual average with a minimum over a day does not make sense.

Last year I drove an average of 54 km a day by car, but the 14 July 2018, I made zero : Mrgreen:

Yes ! that of inciting to read the article, which shows the absurdity of the whole wind.

you should take into account Gauthier's supposed comments. The French energy policy is essentially turned towards nuclear power, the reserves of which are not more inexhaustible than oil and so in the short or medium term the question remains.
Then, it is true that more than the investments to be taken into account (even with their own importance), it is the output that matters because the manufacturing costs have largely decreased, and therefore the (theoretical) billing cost, combined with the gigantism of the wind turbines themselves and which are, for the most part, in the hands of the manufacturers of electricity ... nuclear and which thus make the rain and the good weather in this field.
finally HYDROELECTRIC PRODUCTION IS PART OF RENEWABLES but do not appear on these graphs since their depreciation is largely carried out.

he writes that
the investment remains insufficient - it represents only 49% of new energy projects and does not really replace the existing stock of fossil facilities. We are still far from the levels it would take to comply with the Paris agreement. The insistence that we talk about lowering costs often looks like a way to save face, especially since the costs are far from having dropped by 5 since 2011.

Not only that, he made many other sensible comments, which does not mean that the situation is ideal.

I do not know if in the end the problem is at the level of different technos ....

Wind turbines ... ecologists do not want them
Nuclear ... ecologists do not want it
The dams ... oh la la les écolos do not want it
Coal ... yuck ecologists do not want it
Solar fields ... uh ecologists want ... in the desert and again.

In short the problem is not the technologies are the men ...

If I expand beyond the ecological microcosm then every techno you add ... people want but FAR from home ... basically at the NEIGHBORHOOD, such as prisons, psychiatric hospitals, incinerators, landfills, TGV lines, detours, airports, compost plants, and some of the best.

So what? : Mrgreen:

Inauguration of the largest wind farm in Mexico.
424 MW for 600 million dollars, 123 turbines.

Mexico's largest wind power plant to be inaugurated

August 12, 2018 evwind

It will prevent the emission of 739,000 tons of carbon dioxide into the atmosphere every year.

The project is the result of Mexico's second long-term energy auction, which was conducted by the Secretariat of Energy (Sener) and the National Energy Control Center (Cenace) in September 2016.
A new wind farm will be inaugurated Monday in Reynosa, Tamaulipas.

The US $ 600-million Reynosa I project will have the ability to produce 424 megawatts (MW) of energy and supply electricity to 900,000 people.

Located on the Charco Escondido ejido (community lands) to the south of the northern border city, the 8,000-hectare wind farm was built by the Spanish firm Acciona Energy for the Mexican company Zuma Energía and has 123 turbines, each reaching 120 meters into the sky.
Reynosa II, III and IV at the same site and Reynosa V at a different location 14 kilometers away.

Reminder sting, also valid for Janic : Mrgreen:
Replacing these sources of energy by means whose production depends on the wind and the sun is a real challenge and needs to be multiplied. RTE considers that it can rely mostly on 10% of installed wind power. We must install 10 wind turbines to hope to have at least the power of one. https://theconversation.com/50-de-nucle ... ible-98212

Yes and it's worse for solar!
It may not be "ecologically correct" to say it but an ENR model replacing the current nuclear fleet means more polluting emissions due to the back up thermal to put in place ... maybe we will someday understand that it is our relationship to energy that must be revised (downward) rather than endless procrastination over technological choices.
