Computer jocks and carbon dioxide alarmists over the bit player to the post little ice age temperature rise because of human added CO2. Firstly, get the Physics right and then take a long drive in a 1968 gasoline-guzzling muscle car and still be a conservationist compared to the elites tooling into COP 26 to heat the air with BS on climate change with drama and hysteria. Our know-nothing pampered elite leaders with private jets or government-provided jets to talk about how they can make life much for costly and brutal for the planet going broke with materials intense low energy unreliable energy in solar dilute form. Much better to fund energy research giving the physicists that new futuristic energy research pie. The greenhouse effect, a summary of the article by Happer and Van Wijngaarden By Andy May Figure 1. The calculated outgoing radiation flux spectrum from the Earth, with a temperature of 288.7K. The red, green and black curves represent the radiation emitted as modified by CO2 (in various concentrations) and H2O, O3, CH4, and N2O, the main GHGs, at their current concentrations. The blue curve is the flux without GHGs in the atmosphere. The black curve represents the flow at 400 ppm CO2, current concentration. Green has no CO2 at all and red has doubled CO2 (800 ppm). The x-axis is the frequency in wavenumber units and the flux is in (mW cm) / m2. The additional forcing caused by the doubling of CO2 is the integrated area of ​​the distance between the black line and the red line, major differences are highlighted in yellow. The rest of the figure is explained in the text. The data used is from HITRAN and the figure is very similar to Figure 4 of (Wijngaarden & Happer, 2020). clintel.org/the-greenhouse-effect-summary-of-the-happer-and-van-wijngaarden-paper/

How much energy is required to manufacture a solar panel? I keep seeing conflicting information, some stating that the energy required to buy a solar panel is more than the energy created over its lifetime. The end result is consumers purchase clean energy created by dirty energy - still the same amount of dirty energy being used, no improvement to CO2 & climate change.

More pie in the sky. The panels have a very short life and have to be replaced constantly. There will still be the need for large amounts of fossil fuel. The amount of pollution and heat generated by the industrial manufacturing of all the components needed will be disastrous, not to mention the FACT that we are running out of many of the resources needed to simply produce all these components.

As o the AC vs DC thing, solar panels naturally generate DC. However most electrical usage is AC. But if they want to just directly transmit the current very long distances, they could just collect the DC from the solar farms, and step up the voltage. When it gets over to Europe they could run it through inverters there to get the necessary AC for the local grids.

Good luck guarding solar panels from looters, maintain them (who will be dusting the sand?), replacing them when they fail, operating under high heat destroys their efficiency (which is not great to begin with), etc, etc. Once again, "great plan guys!".

You need to generate 3 xs TWatt. Power. You're converting DC to AC back to DC charging batteries. Each step 30%+ loss in energy. With out distance transmission prob's. In areas that drop below 32⁰f batts only charge to 78% taking over 1/4 longer. Below 18⁰f or lower, req'r heaters to charge at all. Where I live it gets -30 as high for the day. I'm in NY. Thorium salt nuke is better option. Idaho is loaded w it.

How often do the solar panels need to be replaced? The solar panels being used in the Australian domestic market although are advertised to last 20-25 years, really last more the 12-18 years. And the inverters on the Australian market have a 18-24 month fail rate. This is just my observation of all my neighbours installations, and systems installed on some of my relatives houses.

@ rage4dorder 150 x 592 = 88,800.00 x 1,000,000.00 = 88,800,000,000.00 So 88.8 Billion. Ahh the Irish what's one decimal point! Just 80 Billion. And how is this saving the planet from CO2 ? All that heated steel, copper and also one of those complications is heat. So the pipes have to be fill with liquid Gas to cool the line and the gas has to be pumped through the pipes. Gas tanks a both ends or even more places for distance. So all This FREE energy that COSTS REAL MONEY Constantly! It also has to be maintained. All those panels have to be Cleaned from dust. AND SO ON! This is all a big business CON! Nuclear power is the Only Real answer or you nation will be held to ransom. BY SOMEONE! All this when CO2 is not really an issue. There is no debate anymore! That is true just show us the Bloody Proof of the seas rising. Show us the real pictures today of the Melted Ice that will never reform! Show Proof ! There is no CO2 or methane issue. Climate of this planet, of our Solar System and Galaxy are control by factors we have yet to understand. Electric Universe.

Forget transporting energy to Europe. Africa should keep its oil, and its solar energy potential and develop its own industry for its own people, many who live in abject poverty with no power at all, no clean water, no economic activity, no job potential, no education, etc etc etc. There is no reason that Africa should become the solar panel of Europe. Africa can be energy independent and could become advanced and prosperous. Let Europe find its own energy. They already consume more than their share and they have pillaged Africa long enough.

Al Qaeda is, and always has been, nothing but a pseudonym for CIA mercenary thugs. It has no real existence as an organization. Wherever the CIA wants to destabilize a nation or justify a regime change they hire local thugs, arm and equip them, and begin a campaign of violence. And voila another branch of Al Qaeda is born. The same is true for ISIS and ISIL (same thing). It's just that Al Qaeda is supposed to be Sunni fanatics and ISIS is supposed to be Shiite fanatics. But in reality, in every case, they are just hired guns, paid by the CIA to murder people and thereby justify invasion of oil rich lands by foreign super-powers who want the oil.

The simple and romantic idea of generating energy from the sun "for free" is easily marketable to common folk and politicians. Practically however, it is a complete and utter failure, and this video described only part of the reasons. Tiling large areas of land with obscene constructs of mirrors/photovoltaic cells, requires huge costly and polluting support constructs in order to generate and utilize the "free" power. The whole operation also has a very negative environmental impact (which the video did not mention). Instead, why not just build a few isolated and effective nuclear power plants in every country? Much more efficient, much more economical, and despite popular belief much less damaging to the environment.

The whole entire "issue" only came up in the first place because of Europe's own ideological idiosyncrasies. Europe already had a great source of emissions-free power available which works great in its climate, produces gigawatts of power day and night, and doesn't require a lot of land... It's called nuclear, but of course that's the power source that European "environmentalists" hate the most ;-)

The loss of income tax and property taxes from these millions of people. Solar panels have to be replaced and the old discarded panels are very toxic. What do we do with all this toxic material ?

everyone is trying so hard to sustain our current living standard which is really selfish, unnecessary and built around enriching greedy elites. it will all end up failing (solar, wind, nuclear, gas, etc). as long as everyone insists upon 3-5 tvs, 3 + cars, the brightest lights on everywhere, charging stations, i think people spend many hours each day just recharging their various electronic devices, 2 refrigerators or freezers, etc - we will always fall short. we literally have to scale back and go back to just living with the basics. i have always argued for a return to the days when people had underground cellars to store perishable foods, a wood stove for heat and even cooking, and a communal plot of land for growing local food to help relieve the burden of trying to power and import and ship everything. it’s crazy that we have to go burn gas or electricity just to go get food. we should only be buying rice, flours and meats in bulk and growing everything else. that would mean we could cut out the logistics of figuring out how to stock the hundreds of thousands of grocery stores with every single food item under the sun. we should really only have farmers markets instead of grocery stores. but i can’t see humanity scaling back at all. it will take a catastrophic disaster to force us there.

Fusion Energy is the answer. Solar Power is a pipe dream. It can produce some and so can wind but we need a reliable stable source of energy. Fossil Fuels will completely be depleted in 100 years. We have that long to develope Fusion. Not Fission or Nuclear but fussion which is the combination of atoms and equal to the power of the sun.

"The big bad Europeans take advantage of Africans" --*Yawn*-- Europe's (both positive and negative) influence in Africa's history is notable. However, many of Africa's problems are Africa's problems. Just as one would expect a foreign nation might invest in Europe with selfish intentions, so it would be foolish to expect Europe to do any different. Global collaboration towards a better future is important, but similarly to the way European culture did over thousands of years, the many nations of Africa must pull up their socks and eliminate the corruption and criminality of their homeland if they expect to culturally or economically flourish. It is an extremely wealthy territory. Why does the entire world takes advantage of the slave labour in China and nobody bats an eye? We'll see if people refuse to purchase an electric car when they know a large majority of cobalt is mined by child slave labour in African mines. The issue is much bigger and more complex than what has been presented. We must take responsibility as individuals before pointing fingers at other cultures or territories. Hard pills to swallow.

>before pointing fingers at other cultures or territories. Hard pills to swallow. Not at all, not hard at all. What is a harder, maybe, pill to swallow is to see how things are in reality. What you describe is convenient truth, and sure it has some validity to it, or else it could not be that convenient truth, but omitting inconvenient causes out of the picture and out of the mind is what happens in what you describe. It is similar to saying to a prisoner - man be free, grow wings to fly away, and if you can't, no matter why and how did you get there, you deserve that. Or to a poor - to say - man do not be poor - look at Top500 Forbes - they worked hard and see, so work hard - what a BS there are millions of people(10's of millions, hundred's of millions) who work hard every day, but it does not mean Forbes top 1 million will become a thing one day, lol. Fingers have to be put at every valid cause - to understand the whole picture and to find a working solution. Only by having a whole picture can you say what is first, or rather more important, which causes are connected in a reinforcing system of connections, etc. Okay, the whole picture is hard to have, but at least it should be an equivalently correct one, and it includes at least two sides.
