And then we've had the regressive right denying climate change ever since, calling it a liberal hoax, which has seriously stymied the world's efforts and reactions.

It is changing, but it's been grossly exaggerated by governments and companies to bump up prices and squeeze the lower and middle classes. I was referring to us as the human race in progressing and evolving

Energy storage is (typically) expensive so until that changes, the majority of renewables (wind and solar especially) will purely be supplementary rather than direct replacements.

You don't need "storage" in wind energy supplied power grids - the energy flow is direct from the wind turbines farm to the consumers.

As others have said, we should have invested in nuclear.

Nuclear is fine, but also wind, solar, tidal and geothermal.

It would be nice to develop quantum energy, as well.

Deaths in Poland as Storm 'Aurore' wreaks havoc across Europe (msn.com)

"Storm "Aurore" swept across parts of northern Europe on Thursday, leaving four people dead in Poland and causing substantial damage in Germany, France, the Netherlands and elsewhere.

All four fatalities in Poland occurred in the Lower Silesia region.

One person was killed when a van was blown off the road while a builder died after a wall collapsed.

In the western Polish city of Wroclaw, two died when a tree fell, crashing down onto a car.

Hundreds of thousands without electricity
Some 250,000 French homes have been left without electricity after powerful overnight winds barreled across France, Germany, Belgium and the Netherlands.

The year's first violent autumn storm hit large parts of Germany causing damage in several states, as well as knocking out train service.


In the Netherlands, gusts ripped tiles off roofs and uprooted trees in a residential neighborhood in the southwestern town of Barendrecht, injuring at least four people, according to local media.

Firefighters in Westerhoek, a Belgian town close to the Dutch border, said they had been called out dozens of times overnight to deal with storm damage.

What happened in Germany?
The German Weather Service (DWD) warned of wind gusts of up to 105 kph (65 mph) in the north and northeast of Germany throughout the day. Heavy showers and thunderstorms could also be expected according to DWD.

Rail carrier Deutsche Bahn (DB) on Thursday announced the suspension of all long-distance trains in Germany's most populous state, North Rhine-Westphalia. The storm had "severely restricted" train traffic in Germany said the national railway operator on Twitter.

Rail traffic was also halted in the states of Thuringia, Saxony and Saxony-Anhalt in central and eastern Germany.

"Hundreds of our staff are at work removing trees and other obstacles from the tracks, repairing overhead lines and recording the damage," said DB, but warned service in Saarland, Hesse, Rheinland-Palatinate, Baden-Württemberg and Bavaria could be subject to delays and cancellations.

Shipping authorities, too, issued surge warnings for the North Sea and the Weser and Elbe rivers in the afternoon and evening, adding that similar conditions may be seen Friday. Outside the northern port city of Kiel, in Schleswig-Holstein, a tornado tore a "path of destruction" 100-meters (110 yards) wide through the town of Schwentinental according to local the fire department.

In the northwestern city of Delmenhorst, a man was slightly injured after a falling branch hit him on Wednesday evening. In Bad Godesberg, a suburb in the western city of Bonn, a freight train collided with a fallen branch during the night. And in the eastern state of Saxony-Anhalt a man was seriously injured when a tree crushed his car. The 59-year-old was hospitalized after emergency services workers freed him from his vehicle.

Animals at Berlin's two zoos were brought into indoor enclosures and the zoos closed for the day as a precaution.

What about France?
The French national weather service has kept up storm warnings Thursday in northeastern France as wind speeds reached 175 kph in the Normandy town of Fecamp.

According to the French national weather service Meteo France, wind gusts of 153 kilometers per hour were measured on top of the Eiffel Tower in Paris.

Power grid operator Enedis said it deployed some 3,000 technicians to restore power to 250,000 homes without electricity Thursday morning after downed trees toppled power lines.

France's national rail authority SNCF said train travel was disrupted in Normandy and Champagne-Ardennes region, as well as on some routes in the Paris region.

Flash floods also hit the western Brittany region, destroying several houses."

If the grid doesn't want any more supply and the turbines are providing, then without storage, it's just wasted. Storage improvements are vital to making environmentally powered energy supply more effective.

Yes, also what happens when it is a calm day with no wind. The system needs redundancy either through storage or backup supply which is currently fossil fuels.

There are no calm days "without" wind in the North Sea :cry:

You switch the fossil fuels (coal power plants) OFF, and the freed energy needs are delivered by the wind.
So, what you describe is simply wrong and it doesn't work like you want it to work.
 
It's madness that the wind industry didn't have to cost for the supply of back up power in the event there was no wind. We're not as bad as Germany thankfully though, they're much more reliant on dirty coal power on windless/sunless days.

You have no idea what you are talking about.

First part of your post you are implying that the wind in the north sea at any one time is enough to power the entire UK.

Then in your second part of your post, you imply only at some points would we need to turn off fossil fuel related generation. So that's a complete contradiction.

Thirdly, there are times in the middle of the night where wind generated power can actually be no far off UK demand, so there will be wastage there without storage no matter what.

Lastly you've provided a snapshot of the current wind map as somehow proof that there is always some wind?

So all in all you are talking cobblers.

Over the North Sea it is almost constant, maybe 99% of the time!

Do you know what the North Sea is?

Here's a profile of UK wind generation over the last year.

Are you trolling?

Err no.
I only watched a documentary the other day about Lighthouses and how they were built and you are wrong.
Sometimes very calm and sometimes it wants to kill everything, certainly not 99% of the time.
