My Views: I would love it if Solar, Hydro and Wind and other renewable sources of energy + Non Renewable Nuclear were to provide enough energy reliably to completely replace fossil fuels, but I know it’s not a feasible solution at least at this point. And maybe it will never be. Renewable sources of energy are highly dependent on some metal mining (some are rare metals) and I doubt if the prices of those metals would go lower as the demand for those renewable sources of energy sky rockets. i.e., It’s a non-linear equation, the price of renewables will not remain the same if we want to meet 100% of our energy needs from renewables. So, Just Stopping Oil is a pretty stupid idea concocted by people who have a much better standard of living than me.
Skip This if you must: As an Indian, I can speak for 1.4B people (I asked) when I say that, no matter how much pressure developed nations impose on India and countries like India, we will still keep using the least costliest source of energy, because we too want nice things and we too want our women to be liberated from cow dung/wood stoves and from the burden of washing clothes and utensils. So yeah, there is no way bar great scientific innovation which will phase out fossil fuels at least in the near future and perhaps ever.
PS: I don’t like fossil fuels, I don’t like the pollution or the effect it has on the environment and I wish they could be replaced by something renewable, but I just don’t like the chances of that happening.
Idk about Just Stop Oil, but as a someone from Germany, a country that has done what you seek to do, namely moving from 3rd world conditions to 1st world conditions by the use of the cheapest energy source: fossil fuels, there is a sad secret i can tell you:
As per my quick and unscientific calcualtions, Germany used fossil fuels over a period of roughly 120 years to bring ~80M people from 3rd world conditions to the current level, emitting roughly 80bn tonnes of co2 and heating the planet by 0.145C.If we apply this very rough calculation to 1bn Indians (blissfuilly ignoring the rising population of India), Indians will have to work tirelessly for the next 50 years at 2x our speed to do this. So most indians living today will likely never see that dream fully come true.
As a result earth will be heated to 2.95°C (current temp + heating by Indians), a temperature incompatible with boring 3rd world stuff like farming. If we add the african continent (>1.2bn) to the mix (they also want to achieve this, i asked them), it’s more like 5°C.In the end, Indians will have to decide: Do you guys want to want to have your grand-children drive cars, or do you want that your children have stuff to eat.
Here in Germany the people have already decided: We want to achieve a ratio of peope-to-cars of 1:1 (as God planned for us) (We are at 0.583:1), and for that we are sacrificing our grandchildren’s cravings for food (and your grandchildren’s too). But that is ok, because they are not born yet, so we can not hurt them. And also: Food is so boring.
If we fail, and someone forces us to abandon our ways and do koombayah without cars and with renewables (idk that’s Indian i think), we will just say we did not know that co2 was harmful and that we just did what our boss ordered. Worked for our grandparents, will work for us.I already know what Indians will decide, for they are just like us: You will choose the cars.
Peace to India, and remember: We are the good guys, we knew nothing, we just wanted to be happy (life is not worth living without a car).
May contain large amounts of sarcasm, sry for bad english, i’m in a hurry.
It’s absolutely possible to completely switch over to renewable for power creation. It’s just not profitable.
We’ve been fooled to think that things that are “too expensive” aren’t possible. Sometimes that’s the case. Sometimes it’s just us putting money over people.
Not profitable for companies already heavily invested in the existing infrastructure. Solar is now cheaper than coal per watt though for new builds.
If everybody would just stop eating fucking meat we wouldn’t be having this problem. Your addiction is killing the planet.
add in cars and cryptocurrency and having children and we would eventually not be having the problem but vegan alone won’t do it even eventually and nothing will stop it immediately.
Yes it will.
A study mentioned on Our World in Data suggests that if the entire world adopted a vegan diet, our total agricultural land use could shrink dramatically, from 4.1 billion hectares to 1 billion hectares, a reduction of 75% . This reduction is significant because agriculture, particularly livestock farming, is a major contributor to greenhouse gas emissions.
Further, a research team, including scientists from Leiden University, found that if high-income countries switched to a plant-based diet, almost 100 billion tons of CO2 could be pulled out of the atmosphere by the end of the century. This switch would reduce annual agricultural production emissions by 61%, and converting former cropland and pastures to their natural state could remove another 98.3 billion tons of carbon dioxide from the atmosphere by the end of the century .
Additionally, a study by scientists from Stanford University and the University of California, Berkeley, found that phasing out animal agriculture over the next 15 years would have the same effect as a 68% reduction in carbon dioxide emissions through 2100. This would contribute 52% of the net emission reductions necessary to limit global warming to 2 degrees Celsius above preindustrial levels. The phase-out of animal agriculture could create a 30-year pause in net greenhouse gas emissions and offset almost 70% of the heating effect of those emissions through the end of the century .
as what you posts states. it would take time and it certainly does not state that the problem would be over from it as a single action. We have to hit the other big sources as well. You will note it does not say is the largest major contributor.
If people stopped eating meat and we turned the massive amount of land we waste raising animals to slaughter into carbon sinks it absolutely would be enough. But go on justifying your addiction that’s literally killing the planet. I’m sure your grandchildren would agree.
We’re starting to be able to mass produce thin sheets of solar panels as easily as newspaper. It’s time to replace coal plants and switch to renewables.
You can also put wind turbines out at sea and out of sight and add tidal generators below them. But wait there’s more! You can generate power at wave level too! So now this combination generator system can send lots of power back to shore.
…where it cannot be effectively stored at present.
The question is whether it can be utilizied. Some countries do use 100% renewable energy so the answer must be yes.
If by utilised you mean effectively stored and distributed when required, then yes I agree but most countries are a long way from that.
I think you’ve taken a couple of anomalies for the last part and generalised across all countries.
The countries that are close to 100% renewables have unique circumstances that enable them to.
For example, Iceland has a small concentrated population with easy access to geothermal energy.
Paraguay generates a lot of its electricity from hydroelectric dams as it has suitable rivers to be able to build them on. Even so, its citizens often burn firewood for heat.
If we spent 10% of the renewable effort towards nuclear, the cheapest electricity wouldn’t be gas or coal anymore.
So yea, poorer countries with larger populations need to stop being blamed for trying to have a good life, when it’s the rich countries chasing the shiny new thing that keeps us harming the environment
I love Nuclear, what’s absolutely stupid about some climate activists is their opposition to it. I mean, it’s the cleanest and the least deadly form of energy. Let’s hope someday we will reach enough efficiency that fusion energy would be feasible, it’s absolutely everything you can wish for and more. Literal free energy! We have it, it has generated energy, but it has generated less energy than we put into it if I am not wrong, would be absolutely stunning if we can increase it’s efficiency. This is the dream!
We actually got more energy out than we put in recently, but that was in a research reactor and it will take some time to make it actually large-scale feasible. Fission would be completely sufficient on its own if not for the politics. Greenpeace has more blood on their hands than the captain of the Exxon Valdez.
Unfortunately Fusion is too far in the future to solve climate change. There are still a bunch of hurdles we need to pass to start making feasible commercial reactors, so investment into other fields is necessary for the short term.

I did a small project once for my school long ago, do you think it’s more a matter of sci fi at this point than actual reality?
I think that we will reach net energy output within 30 years, with another 30 to actually scale that into a usable reactor, then another 30 to actually start using it widespread, and that’s assuming that costs continue to decrease on things like superconductors, and we get our tritium supply chain to exist. I’m a little biased as a student going into the field, but I’m hopeful.
