How Wind Energy Could Power Earth … 18 Times Over | Dan Jørgensen | TED Countdown
Over the last two decades, the wind power industry has grown at a dizzying pace. (Fun fact: a single rotation from one of the world’s most powerful wind turbines can generate enough electricity to charge more than 1,400 cell phones.) Building off this exponential growth, Denmark’s climate minister Dan Jørgensen lays out his plan to…

Nonsense. The cost of producing, installing, maintaining, replacing, these monstrosities (which are never in the back yards of the elites who so ardently advocate them) must be accounted for, as well as the associated expense of the infrastructure required to compensate for their downtime. My first question is, how much will this speaker personally gain from the growth of these eyesores? My second question is how much will he taxpayers have to pay to subsidize this blight on the landscape?

@Benjamin Henderson Its the same people more or less, behind it, but fossil fuels are not on agenda 230, that’s the difference. They also work, wind and solar, don’t work as advertised and they are not renewable or sustainable. You need fosil fuels to fight wars, to build these suckers, and to dispose of them when they break down. The special composite materials don’t recycle well, so you end up with more waste and when you don’t have enough wind and sun you end up with problems, so you still need classic methods. I won’t even go into logistical, geopolitical and practical problems problems of battery production and usage. But ultimately this is not about technology its about ideology. Religion. Look into agenda 230, or WEF website of the things these genocidal maniacs are pushing for. Absolute madness.

Gas is 3~% the cost of wind energy per MWh, and environmental pledges make up 25% of energy bills as it is.
We have almost destroyed the lower classes on this vanity project already, and you seriously want to push this further?
We need to seriously consider teaching people to ignore the Scandinavians.
This isn’t stupidity anymore, it’s malice.
SeronHD
March 12, 2022 at 10:37 pm
What gas? In which country? Here in europe gas is the most expensive form of generating energy. Also gas has freaking high emissions. Gas is coming directly after coal. And even in the US these numbers aren’t true: Levelized cost of energy for new installment (without subsidies): $37 Solar PV, $40 Wind, $59 Gas. Source: Lazard Analysis 2020.
Aerium Four
March 12, 2022 at 10:54 pm
@SeronHD This is from the UK. and the numbers you provide from Lazard (impressed you know of them tbh) are, as you mention, levelised.
That means it takes into account the total lifecycle cost of a production facility or mechanism weighted against the total output. It does NOT however account for the repair cost of that facility or mechanism when that lifecycle reaches it’s end, nor the issues around intermittency that are a simple reality of “renewables”.
Once these are taken into account, the numbers are substantially different, supposedly at gas: $29, wind: $840, solar: $1,007.
YouTube gets angry with links these days but Sky has a wonderful breakdown of this called Energy Crisis.

@DMminion i dont know man, i dont live in denmark, but unless you have something telling me how it was wind, and didn’t have anything to do with taxes, or covid, or tensions with russia, or anything else i don’t buy it man.
My local energy company gives the option of only drawing my electricity from the local renewables, namely the giant wind farm around here. It only costs me around 10% more than letting them source it from fossil fuels. My bill has held fairly steady going on 8 years now.
I suspect it might be your electric bill has gone up for other reasons.

@Benjamin HendersonI’m imagining if there were a lot more more turbines put in then maybe it can hurt bird populations. Birds need there flight paths that go around the world, the turbines can possibly disrupt that, raptors that love high areas will most likely get killed by these and they were almost extinct in America because of poisons so we don’t need to hurt those populations anymore

Why are the single blade wind generators that sway in the wind not more used? From what I have read they can produce a relatively good amount of energy without them being danger to birds. And were easier to set up and keep maintenance on.

10 GW for 10 million homes.
That’s 1000 watts or 1KW, per home.
The average home is going to require 10 KW, at a minimum. Add on everything like heat, hot water and cooking being converted to electric. You’re looking at more like 20 KW per home
So the 10 GW would power more like 10,000,000 ÷ 20 or half a million homes.
Be careful of the snake oil salesmen!

Lucas Hanover
March 13, 2022 at 1:08 am
@Brett what capacity factor are you using in your assumption? The 10GW is the name plate capacity. multiply capacity factor X name plate capacity X 8760. This will give you generation in GWh. That’s the number you should be comparing to avg home consumption. Your house consumption figure is in the wrong units and doesn’t make sense…

Storing electricity in hydrogen is super ineffizient. Use batteries, they have been designed to do. And you are 60% more efficient so you can cut oil production much earlier, because 2050 is just rediclious.
Yasmine Steinbauer
March 13, 2022 at 2:25 pm
@TschingisTube Through a simple chemical process, the hydrogen can be converted into methane gas by carbon dioxide. This is then equivalent to natural gas and can even be stored in the same tanks.
TschingisTube
March 13, 2022 at 2:54 pm
@Yasmine Steinbauer So we are going on and wasting even more energy, because electrical energy is the kind of energy we have in excess and if we don’t we just build more wind power so that the investor of the wind power does not get any in return since we force him to deliver all energy for free so that we can waste it in all processes? Simple as that. No change required. We can burn our natural gas, even drive cars with it and maybe also mix it with gas from some super reliable countries if it does not work out?
Yasmine Steinbauer
March 13, 2022 at 3:05 pm
@TschingisTube A gasoline-powered car also has an efficiency of only 25-30%. But that doesn’t upset you? Only when it comes to renewables you are suddenly interested in efficiency. We are by no means mindlessly building up capacities in order to then also mindlessly waste them. There are precise model calculations for all that.

Also, concentrated solar power is much more efficient than wind. Wind may not flow for days but sun will always come up in the sky.
Also, tidal + solar is a much better alternative to wind because tides will never stop. As tidal energy is relatively expensive, it can be used when solar energy is unavailable.

We in the U.S. can’t seem to get passed the special interests, rich waterfront homeowners (Cape Cod,) fishermen (Maine). and others, so we can build wind turbines in one of the best locations – the near offshore. All the advantages of offshore wind turbines exist near shore including strong steady wind, shallow water, and most importantly, close proximity to cities that consume the output. It will take federal government intervention to overcome these special interests for the benefit of the greater good.

@Turning Point Indeed it depends and very costly to deploy over water. Green energy was tried in Ontario Canada and scrapped after spending 100s of millions due to the high cost. Spending more than the energy being harvested. Wind farms was an issue due to impact on birds and noise level created.

Turbines are not without problems. One of them is infrasounds, specially if a lot of them are together the low vibrations can disrupt small animal behaviour and even human sleep that could lead to anxiety, among other problems. I’m not saying they should stop, but they should definitely look into it.

Because we live in a world of inflation, any money you keep in cash or in a low-interest account declines in value each year.

As an investor a portion of the portfolio needs to be invested in equities to beat inflation. It’s important to remember that there are two ways to lose money: your $1 decreases to 90 cents or your $1 only buys 90 cents’ worth of goods in the future

Texas is generating 22652 MWh of wind energy at the time of this comment, and none of it is offshore. I understand that Denmark does not want turbines on much of its land, but this TED talk is only about thoughts and dreams instead of reality. Denmark can do it, but they need to do it now or try something different. They can help Iceland with green hydrogen, for example, or they could ask Uruguay for advice.
