Only 43% of Americans are for a government run health care system according to the Gallup polls you just provided. That basically excludes single payer health care. What Democrats believe does not matter, as it does not win elections.
Politicans try to judge public sentiment and what it could turn into and only do act, when something is populare. Even then they are more likely to not do it, but for the most part they try to be reelected. Hence trying to appease donors and the public. The simple dumb truth is that climate activists in the US have failed to lay the groundwork for a strong climate policy. Most only just agree that something should be done. Actually doing something, which requires some sort of sacrifice is not going to happen.
The advantage of having somebody like Harris is that they are more likely to actually enact left leaning policies, if they are populare enough. Never expect them to do anything even when necessary, if it destroys their chance of reelection. This also includes all other politicans and last time I checked a president needs the approval of the House to enact laws.
Thank you for summing up the video under my comment. I make sure to edit the post. Thanks very much!
Algaculture would be intressting as well. It is still relativly uncommon in the West.
For canals electric ships are an intressting option. Solar powered ferries are a thing, but also cable powered ferries.
Another one is swimming in canals and rivers. Especially in cities this is often not a good idea, due to bad water quality.
Commuting via boats and ferries. When you have a large river, why not commute to work via stand up paddling or in a kayak?
EDIT:
Also hydrofoils are pretty cool. They allow for greater speed on water.
She does not want to talk about it. However she has actually a pretty good record of supporting climate action like sponsoring the Green New Deal, which she mostly got passed in form of the inflation reduction act. Action is worth so much more then words.
The reason she does not want to do it, is that it is better to run on women's rights and workers rights. Trump has an awful record on it as well and a lot more people care about it.
Btw the author currently sits in the UKs House of Lords for the Green Party.
Or it is due to Chinese banks making paying for the oil more difficult.
Hydrogen can be stored in underground caverns and that can be relatively easily scaled to TWh. Electrolysis and fuel cell can get you 70% or so of your electricity back. So it is less efficient then batteries. However there might be a place for hydrogen as seasonal storage. Also the storage makes sense as quite a few processes use hydrogen anyway.
So there is a use case, but right now we mostly should just add renewables and batteries. We are nowhere close to a solar/wind grid, which does actually need seasonal storage. Also grid size helps a lot and there are options such as burning waste.
There is a lot besides an actual peace plan Modi can be usefull for. For example Ukraine captured a lot of Russians in Kursk and Russia still has Ukraninans from the beginning of the war. A prisoner exchange would be usefull for both sites. Also just getting an idea what Russia is willing to do for peace is at least intressting. If their proposal is somewhat serious, then they might run out will to fight.
Seriously in Europe many investment funds activly go to the unions and ask which problems the company have. They are often better informed and honest then the normal management. They also have an obvious intresst in keeping the company around.
A tax rate for billionaires of 200% seems fair to me...
