Renewable Energy Advances

[Catsumi]

I think it's important to consider all options when it comes to energy, including renewable sources like solar and wind. While it's true that they may have hit their peak efficiency, it's still worth investing in them as they offer a cleaner and more sustainable option for the environment. Plus, with advancements in technology, there's always the potential for further improvement. As for the argument about burning trees, I agree that it's not the best solution. However, it's important to remember that not all "left" individuals hold the same beliefs, and there are varying opinions on the matter. It's also worth considering alternative solutions, such as biomass energy, which utilizes waste materials to generate power.

Windy has produced many well-blended birds, sadly. Also, as has been said many times over here, those gigantic blades are impossible to recycle so they are sent to graveyards in the desert

I agree that high temperature burning of waste materials is a terrifically good idea. The Japanese have been doing this for some time now with great success. Why not here as well,or must we re-invent the wheel over and over.

'Considering all options' is a long-term cost benefit analysis. If a hydro plant or nuclear plant generates x, costs x, and lasts for 100 years, is that better than rebuilding the same non-recyclable wind farm 5 times?

I think incinerators are a good idea for electrical generation. Our plastics and papers can go in to it. Only 5% of what we call 'recyclable' is really recyclable. Problem with biomass is it emits all sorts of particulate and hazardous fumes since there is a lack of concern over what is burned. Trees in BC go to the UK to generate electricity. I don't agree with these forms of capitalization.

Solar panels and wind turbines not only have peaked as far as efficiency and performance, they are intermittent. One does not realize the full benefit of wind and solar unless there is a means of energy storage. Not only that, one has to over-build renewables to generate enough. Grid size batteries have been in the news for going up in flames. The entire 'sustainable' solution is complex, wasteful, and requires lots of real-estate. This is not good for the environment. Of course, wind and solar have never been as much an environmental solutions, as a 'climate' solution to generate fewer emissions. Maintenance of wind turbines maims and kills many people every year and cause the cost of electrical generation to skyrocket. Smart people do not want unreliable renewables if reliable baseload is available.

The best renewables is hydro. Solar and wind barely break even with the amount of energy required to create them. Enormous swaths of land are dug up, or these things are put in the ocean where they interfere with marine life. They are hardly 'environmental' solutions. The best 'environmental' solution is nuclear and NG. Solar and Wind hurt the environment because they are not an energy dense solution.

The best way to reduce emissions is to convert coal plants to natural gas where it can be done. We still need coal for steel production. China is building many more coal burning plants too.

This is all under the assumption that more CO2 is bad and there is a pending climate catastrophe on the near horizon, which there isn't.

Agree with you as always Jlabute dearie, however the Japanese employ extremely high efficiency burners with multiple scrubbers so that particulates are not a problem. Parks, beautiful parks surround these burners which produce power for home/industry consumption as well as producing blocks of solids as an end result used in building pathways, garden furniture in the parks as well as retaining walls.

They also burn hospital waste which turns out the same power and blocks, perfectly safe for human use as an end product.

Why we can’t do the same as they do, is simply beyond my understanding. Instead, we truck waste from Vancouver to Merrit to produce what?? We pack our landfill areas, to what purpose, and obtaining more landfill areas is getting very expensive.

When I visit Osaka in the fall I will take photos of beautiful “incinerator park” and post here

Lucky you! I can hardly wait for pictures. I think a lot of people will want to see those.

A costly investment.
Germany spent nearly $500 BILLION on wind and solar power. The result: Germany's dependence on fossil fuels declined from 85 per cent to 79 per cent over the last 20 years.

More on Germany.
Nuclear power provided almost 30 per cent of total German energy needs in the 1990s. Today, it is zero. If that share [of nuclear] were maintained, coal power could have been eliminated.

Just when you thought you had a really cool expensive 5.2MW solar farm, and it is wiped out by huge hailstones. This is how insecure renewables are.

The solar array wasn't installed soon enough to stop the climate change that caused the hail storm. Just a guess but sure would make a great news headline...lol

[seewood]

^^^ going to have to dig a pretty deep and big hole to bury all those useless panels. Hope they won't affect the water table.

[GordonH]

I’m curious on how many hectares of valuable agricultural land was used.

I don’t have a problem if they use unusable farm land to install their solar collectors.

I thought solar energy was renewable. How are those panels going to renew themselves?

"Unusable farm land" is also part of the natural ecosystem. Many solar farms are responsible for disrupting sensitive desert and semi-arid areas regardless of the impact on species at risk. The hypocrisy of destroying natural environments "to save the planet" with renewables flies in the face of true respect for ecological diversity and environment.

Strange thing is Nebraska is dead center of the hail belt. Anyone would have guessed enormous hail would strike at some point and destroy the array. No one cares about the environment, or even basic site requirements and locations when it comes to spending on renewables. Renewables exist to make a certain tiny portion of the population feel better, like prayer beads.

Now that the array is destroyed, we can say it wasn't worth the energy in the first place to build it. Replacing it puts the project in a cost and generation deficit that isn't even worth the effort and cost over 20 years.

And this was just as predictable as the fall of Rhodesia but here's the thing, people don't want to hear it. And that's how this happened, this massive transfer of wealth that resulted in almost zero power generation. Such idiots.

I actually do have a problem with this as there isn't a thing in Canada as "unusable farm land". Land that isn't suitable to grow crops still has value as grazing land for cattle and sheep, which is far more valuable to mankind than useless solar panels or even worse, bird blending wind turbines. Quick Dick the Saskatchewan farmer did an excellent video on this - and how he uses unplantable farmland to grow food for Canadians. Which has a lot of value.
