When it is all said and done, "societies are dynamic just as the planet we call home is, the only sure thing is change". It is hard to allow for every disaster and every corrupt leader.

LOL good point . Problem is every Leader these days is corrupt . What surprises me most is we live at a time when you can find out just about anything you want. You can repair and build stuff you've never done by just watching a video . Vast knowledge is right under your nose . Yet the vast majority of people with all this knowledge at their fingertips. Have no clue how bad things in the world have turned since the Big C. Sad

It's unfortunate there are so many deceptions these days . You don't know what to believe anymore . I don't know what's worse people who are scared about everything . Or those who are in such denial they don't believe anything they interferes with the bubble they live in .

You will only feel that way if you refuse to exercise any amount of critical thinking.

Let me get this straight: a super-secret US Intelligence Group spins out to the public and makes the remarkable prediction that two-thirds of the US Population will die (or emigrate) in the next three calendar years. No specific mechanism is given in the "report" for how this even happens. Mention is made of biological warfare, mass suicide, and financial collapse. But no specifics as to how exactly this is going to happen.

I checked out this Deagle Group and their website appears to be a collection of Wikipedia-level information on countries joined with public counts of military aircraft. There is no "About" or "Contact" links to be found on this site. Some of the terminological and grammatical errors seen lead me to believe that the authors couldn't possibly be native english speakers, and probably passed their originals through some translation program.

If you dig a little further you will find this "prediction"has been circulating for many years, at least back to 2014 and possibly much earlier. And the "report" doesn't match the formats and terminology any government or analysis firm would use for something like this -- this work product didn't come from former or current employees of the US intelligence bureaucracy.

Oh, and deagle.com was registered on February 9th, 2000. So if it was a spinout of US Intelligence that spinning out happened when Bill Clinton was president.

My point was it's all deception to push fear we need to go Green to saved the planet .. We can't support the planet with Green . Impossible

 

[Zekeer]

I'm sure you realize it wasn't towards you . My point was there's all this deception . But is it really deception ? Or are they telling us what they are hoping to do . In a way that appears to be fake news . Somewhere years ago I read that the plans of the wicked are always revealed : Because they can't help but boast about what they are gonna do . If you live in America or anywhere in the West . News has become nothing but fear and hate generating tactics

It's really easy
Step 1...put your mouth on a gas powered cars tailpipe for 1 minute
Step 2....do the same with an electric vehicle.
Step 3...come to your own conclusion

HUH LOL LOL Actually putting your mouth on a tailpipe would burn it so badly you'd have to be pried off. LOL That's not a very fair and honest example . Since the E-bike wouldn't exist without C02 and Coal . First off C02 is fantastic for the environment. Everything GREEN Loves it . And in turn for us feeding them they supply us with oxygen. Now on a serious note . Think logically if C02 was dangerous to mammals or to the planet . We'd be suffocating . Besides the batteries we have in our bikes required both coal and gas to be made . You're frame required gas ,to be molded and welded . Solar panels require the same things . When thrown away after 20 years they damage the dirt and topsoil. Not to mention the people that are forced to make solar panels die of cancer inside of 15 years . And yes they are forced by China to work in these places . Don't get me wrong I'm all for some green renewables . But who are we trying to kid .
What gives us the technology we all have at the touch of our fingers is Gas/Oil and Coal . That's what brought us farther in the last 100 years then we had advanced in the previous 5000 years or more .
You'll see when thousands of the elderly die in Europe for lack of heat this winter . That's not speculation either

Green renewable energy as a source of advancing is like dying your hair when you're 60 . Or putting lipstick on your pig and telling the neighbors and friends she's your girlfriend .

Citation please. I've heard that assertion multiple times and haven't ever seen the hard numbers that would back it up.

By "Green" I am assuming you refer to PV solar and wind power.

I can't overemphasize to people that there are different definitions of "solved": maybe you can make the physics work, then perhaps you can build a practical implementation, and then there is a hope you can build a version that is economically feasible. None of those steps are necessarily easy and just because you've solved the first one or two doesn't mean you can save the world with it.

It's interesting to see how many valuable points you bring up in what seems to me a futile effort. Thank you, though. And after the technology exists, then money (who pays?)and a host of other bitter social issues have to be resolved before anything is implemented. My focus is what people, not corporations or gogovernments, are doing right now ..

Aside from transitioning to renewable, the elephant in the room is that world economies will have to abandon the growth principle on which they are based.
We simply cannot keep on growing the economy, it is just not sustainable. A new model is required.

There is a great comic book made in France by eminent researchers to make a lot of hardcore data be more palatable.
It has now been translated to English, it is full of good information

Wow... That hurt to process.

 

[Zekeer]

Wow... That hurt to process.

True things usually are hurtful . I can see the climate storms and flooding is getting way more intense . But then you read about all this cloud seeding and how it's used as a weapon . one has to wonder is that what happened in Pakistan ? 1/3 of the country is underwater . Besides the reason I know all of this Climate Change is nonsense being used to control us ? Take a look at Davos and the WEF . They tell us the Oceans are rising at alarming rates . When they are buying up Beach front Property. I agree that the climate is getting much more violent . However, It's not caused by C02 . If it was wouldn't the thing that would stop C02 emissions the fastest be to eliminate Carbon footprints ?? I mean the kind that have arms and legs :

You speak of all this hope . That's all fine and dandy . But you don't build a bigger home to move into and tear down your old house before you've even laid down a foundation to build the new one do you ? That's what they are doing . Getting rid of gas when there's nothing to replace it . Spending mountains of money and producing nothing for it ?? That is why things are inflated so much so fast . Closing down coal mines when you need coal for Steel and batteries as well as heat . You're asking for hard numbers to back what up? Common sense does that .
If we shut up our gas supply . What we going to use until your hopes happen ? For that matter where is the money going to come from ? The Dollar has stayed #1 because it's the reserve money to pay for gas and oil. If they eliminate the dollar will plummet over night . It already is going down .

The dollar has dropped 13% and the Euro has increased 3% since 2020 . THe Euro even worse because of America free wheeling spending .

All one has to do is look how many 100 windmills it takes to power a small area . How could we power big cities that way ? Was it 2 years ago they had that hard Freeze in Texas and people died because there was an issue with fuel lines and Green energy windmills all froze up and couldn't pick up the slack ??

Of course that's not the way mainstream Media spun it .
There's been report after report on how Chinese People are forced to work in Solar mills . That it is a job you die at after 10 years 15 at most . That's not conspiracy theory . It's just not spoken of so people forget or don't even know it .
The world's a Mess . But if you watch the News in America . You'd think the biggest problem is Donald Trump and Jan 6 th .

Bottom line with Gas/oil in the meantime . The world can't maintain the level it currently is

Out of respect for Mr. Deco I'm going to refrain from being my usual congenial self and take an ignore.

Funny you should mention windmills.

My first observation is that you can do other things with the land you have wind farms on. Note the emphasis on wind farms.

Pretty standard engineering calculations at this point shows that a typical wind farm generates 1Mw per 0.75 acres.

Now there are 915 million acres of farmland in the United States (USDA).

Now through the magic of multiplication, if through some reason we decided that all farms should also be wind farms, we'd have a generating capacity from just wind turbines on farms of 686 million megawatts.

I note that the current generating capacity of the entire United States is about 1.1 million megawatts.

Of course, you do need to take into account the capacity and utilization factors. Even making a very conservative assumption that any given wind turbine would only be generating 15 percent of its capacity (real-world numbers are between 25 and 50 percent) we still are generating over 102 million megawatts -- approximately ninety times the current US generating capacity. Note that doesn't include existing hydropower and nuclear plants, and I reasonably assume we'd keep most of them for their useful lives.

I haven't even mentioned that we could also put wind turbine on the land that we use to grow cows. There are approximately 770 million acres of rangeland in the United States distinct from the farmland mentioned previously.

This of course assumes that we'd restructure our grid to distribute that energy efficiently. Given that our power grid is over a century old it is time for a remodel anyway and we might as well get it right.

So using 4th-grade math I've shown that we could get there with wind power and some slight remodeling of farmland. This is more rigorous work than I've ever seen from any of the naysayers who just say how it is impossible. The physics and the engineering work, and given the recent cost figures showing that on-shore wind is by far the cheapest source of electricity today I think it a safe bet that the economics work too. Notice that I left out offshore wind power too.

Now, back to the topic.

I'll do a similar calculation for solar power. Let us assume that we decide to put sunshades over all of the parking spaces in the United States. There are estimated to be between 800 million and 2 billion parking spaces in the United States. Pretty standard size for parking spaces is ten by twenty feet, so you can pack 225 parking spaces in an acre (I don't count the lanes you need to drive the parking space, and also ignore that a lot of parking spaces are compact and smaller -- for a Fermi number those two probably cancel out).
I'm also going to ignore multi-floor parking garages. My argument would be that if I use the lower number and make some reasonable assumptions about the prevalence of multi-floor parking garages the numbers again about work out.

That works out to about 3.6 million acres used for parking in the United States if you use the lower number.

Now generation per acre for PV is all over the place, with estimates from 0.1Mw/acre to 10Mw/acre -- I'd guess that is because they are including capacity factors in their figure, and capacity factors will vary by location far more for PV than for wind. Just to make this easy I am going to split the baby and use 1Mw/acre.

So you lead the conclusion that PV panels covering all parking in the United States would generate THREE TIMES (THREE TIMES!) the amount of electricity we currently generate.

My conclusion is that not only can we go to 100 percent renewables and generate just as much electricity, we'd have an insane amount of growth capacity to power all of those new electric cars we'd need too. And probably have a few centuries' of headroom for generating more electricity if we decide we need it. All at far lower costs than our current electricity generation systems.

Again, with 4th-grade math this is a no-brainer.

 

[kevinmccune]

It's really easy
Step 1...put your mouth on a gas powered cars tailpipe for 1 minute
Step 2....do the same with an electric vehicle.
Step 3...come to your own conclusion

Or run both in a small closed room for a while ( just do not lick the battery terminals)

That's great for everyone except the handful of people that like to temperature control their abodes at night when the sun isn't out and wind velocity typically reduces.

There needs to be more attention given to methods for storing energy harvested during the day for use between 4 pm and 9 am.
