How cheap renewable energy is finally flattening emissions

Video Overview & Insights

Correction:

China is cheaper because of low wages, access to resources and the government basically not having to deal with Legal issues, environmental issues, and local push back. They do what they want.

— @brianyegerlehner9157

1:15 The graph has mislabeled trend lines. "Other renewables" generate more energy than hydropower alone.

For decades, rising carbon emissions have accelerated climate change, but this year marked a critical turning point that could finally reverse that trend. Renewable energy has now graduated beyond the need for subsidies and incentives, emerging as a cheaper alternative to fossil fuels in many countries. News Editor Tim Appenzeller and policy expert Li Shuo describe the economic forces behind this shift, and the obstacles that remain to the continued rise of green energy.

is anybody able to stop this BS...
how keen is Bowen or Miliband, to tell us that the cheapest form of energy is solar or wind, when we all know, especially now, how it all starts, massive mines with massive road infrastructure, then the hundreds of diesel trucks etc. then the transport of the materials to the refineries, the transport to the factories, then the transport to the shipping yard, then the trip across the ocean, then finally the transport to the land site, and this is just the beginning.. now the site development, the infrastructure, the thousands of metres of cable, inverters, transformers, all before you start on extending the grid... and what have you at the end, a 30% efficient system producing an asynchronous/unstable power... now they have the gall to add batteries, as if they magically appear without all the same destructive process and with at best a 4 hour back up...

Maybe I have no right to say this, but with my 10% knowledge of this field, even I would challenge Bowen and Miliband to a live conversation, but with one catch, if I can prove it be un costed, un viable scam, killing of businesses, and creating financial and emotion strain to everyday citizens, then they must be sacked on the spot, because they have scammed us long enough...

Read the essay: https://www.science.org/content/article/breakthrough-2025

Is it 'flattening' emissions enough? A lot of guess work going on. As far as I'm aware, the anticipated fall in China's emissions of 7-10% by 2035 will not be sufficient to stay below +2°C. Trump et al. appear to be doing everything possible to ensure this.

I watched this video when it first came out and there have been huge gains in renewable energy since then. Please continue to follow this transition. Petro states with solar farms and former opponents of renewables choosing solar panels to offset home energy usage.

There's a huge difference between the graphs at 1:14 and 6:12. I guess that's because the earlier one includes fossil fuels used for heating and transportation? I have to admit, it seems unlikely that we'll be running smelting plants on solar power anytime soon.

BREAKING NEWS - THE NEW YORK TIMES

Climate Scam Officially DEAD! New York Times SHOCK OPED: ‘Forget Climate Change. Democrats Need to Talk About Other Issues’ – ‘Marks the end of an era’ – Admits ‘American voters largely do not see climate as a top

NYT OPED by a progressive socialist, Matthew T. Huber, author of “Climate Change as Class War: Building Socialism on a Warming Planet."

'There is little reason for politicians like them to focus on the issue anymore' - Go silent on climate 'to regain credibility with working people' - For 'blue-collar voters, energy is an 'end of the month' issue'

Democrats need to 'stop elevating a litany of single-issue policies'

'American voters largely do not see it as a top priority'

You have all seen the really cool photos of our little rock under the stars, right?
How many of those lights are somebody reading the newspaper and how many are on in empty office buildings, big city boardwalks and all the other corpoRAT money making schemes while we foot the bill?


Looks damn suspicious to me to see the new lights lighting up eight blocks of my little downtown at 10 pm and the only souls around except the attendants in the 3 gas station attendants and me when they want to add a mil to pay for the electric bill now because of the new lights. . .
I am not complaining about the stations being open at 4 am when I needed more Code Red but the lights were still on downtown and I woke up one of the 3 sleeping attendants at the main intersection of this little burg of mine . . . ;>)

The energy source with the highest energy density has to be wave powered devices. Moreover it is an energy source that if the spot for collecting that wave energy is constant, then day and night it will provide power. However the trick is to engineer such a device, and transport the power generated at sea back to shore. There are a multitude of design concepts for devices to harness sea wave energy, and all of them have a variety of problems. The major problem with any device designed to work in the sea, is the salt water, that corrodes metals. However with careful design and material selection, a device can be engineered to work out at sea. Maintenance is the next major problem and thus the design with zero maintenance will be the most suitable one. There is more than enough power in the seas alone to power our world hunger for electricity, and thus to me therefor sea wave energy harnessing is the best way to go long term!

Our new house has super high insulation and powered by electricity. I installed R35 foam insulation in the attic, R28 in the walls and R10 over the concrete basement floor with blue DMX dimple mat first. Next year I'd like 10 solar PV panels on the southern roof and the year after a residential battery system. My top concerns are climate, comfort, energy security and mid term cost savings.

We had solar on our modest bungalow very early, two years ago batteries, and last week a heat pump.
Thanks to the government grant.
We watch events in the Middle East, the marching backwards of the USA. The shear economics of solar and wind power, against vested fossil interests,will win out.
But climate change runs on, has a legacy for future generations that will be grim.

propaganda

@standingbear998

I'd be very interested to see maybe a follow up or rework of this video that does a few things:

1) Isn't Chinese propaganda
2) Discusses the cost both economically and environmentally of building all of this infrastructure.
3) Covers the environmental impact of manufacturing 'green' energy, such as the rare-earth minerals required for solar and the damage to environments to build solar farms and their battery facilities.
4) How we will power large vehicles, such as cargo ships (one of the largest users of fossil fuels) with the use of solar energy.
5) An actual plan for implementation of these on a large scale, what that would look like, how long it will take, and how to do that without collapsing the economy or having world-wide shortages.

I feel that this video is deliberately leaving out some imperative data about these energy sources and only telling one side of the story; that's making it difficult to see it as anything other than a sales pitch for Chinese solar panels.

If you want ONE argument in favour of renewables: Energy SECURITY. Decoupling as much as possible from geopolitical turbulence in the energy market will stabilise economies. In Britain we are experiencing horrendous fuel hikes thanks to the war in Iran. If we can utilise more solar and wind energy, we need less hydrocarbons, and can temper the impact. Yes we are importing the technology to produce that energy, but once my roof has solar on it, I'm set for 25 years. The further we go, the more secure we get.

I have a 660w panel that I got dirt cheap second hand, no way to tell that it's not new. I charge an ESS with this panel. My computer and all of our other portable smart devices (phones, tablets, laptops) are fully powered by green energy. I don't own a house or I would have completely cut off the power grid and switch to solar power.

@نادرالیراحمان

The part about solar costs dropping 90% in a decade while fossil fuel costs stayed flat really puts the economics argument to rest. What I find most underreported though is the speed of battery storage cost decline running in parallel. Once storage catches up to generation costs, the intermittency argument basically disappears. Anyone tracking where battery cost per kWh is heading by 2030?

@StraightTalkwithMattWaterman
@

2:30 Pivot is a poor choice of words imo. Coal is still pretty important to China, see energy security during US/Iran war, and they have still develop these plants with some of the most advanced/efficient new coal plants in the world. Which also helps the effect of flattening emissions through efficiency gains.

How much fossil fuel to build maintain and replace wind and solar systems? And, how is the energy equivalent to fossil fuels coming along? Because right now. 10% of electricity comes from renewable systems and electricity is only 20% of the energy used by civilization and of that 20% fossil fuels make up 80% of the energy inputs. Even nuclear requires a great deal of fossil fuel energy inputs. So, if all the energy called renewable were to be added up it would amount to about 4% at this point in time if you exclude human and animal labor and much of that is fed by fossil fuel agriculture. I want to be clear I'm not against renewable energy I'm just hoping you will consider the scale of energy that maintaining modern civilization currently requires. The good news is that our current system is about 70% waste meaning that our economy is primarily based on waste rather than need or even quality of life. We are wasteful to support the economic growth ponsi scheme. We're wasteful with transportation agriculture packaging and basically how ordinary modern life is arranged. This can end the hard way or the harder way.

@davidcanatella4279

Flattening emissions is not enough. They must be cut by at least 50% in the next 5 years. Not just because of the effects of the emissions on global warming, but because any carbon dioxide emissions are a sign that we are still using up the cheap energy stored in fossil fuels. What we have left is not enough to meet usage demands AND supply all the embedded energy needed to fuel the transition to renewable energy sources.

Chicken Little came out twenty years ago and told us the sky was falling and that our coastal cities would be underwater by about 2014. He said we needed to pay carbon taxes in order to fund drastic measures like constructing wind and solar farms all over the world, or else we were all going to die. Here we are, twenty years later, and the ocean isn't any higher than it was fifty years ago. The justification for wind and solar was, conveniently for us, untrue. But they are still pushing the same agenda.

They claim carbon is a greenhouse gas. Is that even a bad thing? The only reason there is life on this planet is because our atmosphere is a greenhouse. Plants feed on carbon dioxide and produce oxygen. It is a cycle of nature. There is also a climate cycle that waxes and wanes over periods of decades. And a water cycle that exists in three states, not just two; liquid, ice and vapor; all designed by God.

The atmosphere has about forty times more volume than all bodies of water on earth. When the climate gets warmer, there is much more water vapor in the atmosphere. Clouds water the Earth, shade it from the intensity of the Sun and cool it back down. It is all part of the natural cycle that God designed.

Genesis 8:22 As long as the Earth remains, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease.

I love solar power. I've been off grid and on solar for six years. I always say, I have everything people in town have, except the bills. Instead of covering the good green earth with wind turbines and solar panels, let's put solar on everyone's homes and businesses and get off the grid. They can use the power plants for more industrial purposes without having to perpetually increase their output. The idea of trying to power the entire world from remote plants and send the energy down thousands of miles of wire will never be sustainable. Put the power at the source of it's use.

Do you want to be “green”? Industrial wind and solar farms is not the way to do it. Get back to the land and homestead a real farm, even if it just a backyard garden. Self-sufficiency is the is the real way to be green. The more we can do for ourselves and our community, the less we will be dependent on their system. We've almost forgotten how to do this, but maybe it's time we relearn the wisdom of the past. It only becomes hopeless when we give up and give in.

Wind and solar depend of ruining vast amounts of land...they take up multitudes of miles and make what land they stand on unusable for anything else. So, they are not the best solution to constantly increasing energy demands.

As long as you continue with the frame that renewables are virtuous and burning fossil fuel is evil, don't be surprised if people think that you are a cult.
