>1) in my country the grid uses 70+ renewable energy (mainly hydro), so EVs are extremely promising.

Sadly that's not the case for most of the world. Petroleum, natural gas, and coal—combined accounted for about 77.6% of the U.S. primary energy production in 2017. Fossil fuel energy consumption in China was reported at 87.48% in 2014.

> progress made on EVs will pay off in the future, when/if the grid becomes greener.

Only if new battery technologies are created that can be manufactured quicker, in a greater capacity, than lithium batteries are now.

>There’s little risk of lithium supplies running low in any absolute sense; the next decade will probably see less than one percent of the world’s lithium reserves depleted. The real danger is that lithium won’t be recovered and made available quickly enough to meet the rising demand.

>There are two sources of lithium: brine and mineral deposits. Brine is recovered through a process known as brine mining in which dissolved lithium (and other useful elements) are extracted through a long, energy-intensive, and costly process. Recovering lithium from mines is more straightforward, but most of the world’s lithium is in brine pools in South America. About half of the 35,000 metric tons produced in 2016 came from brine operations in Chile and Argentina.

From the same article we also have to factor in how rapidly lithium prices are increasing:

>Anxiety about lithium’s availability has caused its price to spike. In 2010, lithium sold for $5,180 per metric ton. By 2012, the cost was over $6,000 per metric ton, and by the end of 2017, a metric ton was going for about $14,000 – a 270 percent increase over 2010 levels.

So what happens when you start churning out EVs 10x faster than Tesla is, 100x faster?

And how much more fossil fuels will need to be burnt in power plants (it's worth noting that roughly 6% of power generated at a power plant is lost in transmission before it arrives, then more will be lost changing voltage at a charging location, then more as it feeds into the battery) instead of as gasoline as more and more cars come online? And all of the infrastructure that will have to be created to support them? 17% of Americans live in an apartment or a condo, they can't just pay to install a plug in their garage as in most cases they do not have a garage or even a dedicated parking spot and businesses, you're going to have to convince businesses to spend large sums of money to install charging infrastructure in their parking lots for tens or hundreds of parking spots, and likely to support that new lines will have to be run to the area, widespread adoption of electric vehicles in a country like the United States suddenly means tens of billions of dollars in just power lines and substations, wiring and charging stations.And adding a bunch of EVs will mean you'll need to add a bunch of grid storage or bring more fossil fuel plants online to meet the demand of all of the cars getting plugged in at 8-9am in each time zone as people arrive at work... renewable energy doesn't work well for spooling up to meet demand.

Plus with widespread EV adoption in a given country you have to basically retool every firehouse in that country to also be able to handle EV accidents, pierce a cell on an EV and you have a fire situation that can last DAYS as cells rupture one by one in a worst-case scenario (like when Richard Hammon crashed that Rimac Concept One supercar).

>Yet your comment is written as if it makes no sense. It conveys a strong sense of doom and pointlessness.

No my comment points out that the organization Wren keeps listing, has a bunch of whimsical fantasy ideas that are not remotely viable and I don't see why I should give Wren my hard-earned money to take 20% for themselves before they hand 80% over to organizations, or individuals, that are chasing fantasy technologies that won't be viable for decades, if ever.
