It is actually cheaper and greener to burn fossil fuels to make electricity for EVs, and just capture the CO2 emissions released than to produce hydrogen.
Virtually 100% of H2 sold today is 'blue hydrogen,' meaning it is derived from steam methane reforming of natural gas, a process that actually generates more Greenhouse Gas than simply burning natural gas [1].
'Green Hydrogen' produced from the electrolysis of water is incredibly expensive (about 3-4x more than Blue). Both are mature technologies that are unlikely to get cheaper at larger scale.

Because these leaks can occur spontaneously, you really want real-time, continuous monitoring of a wide area with high resolution. Aerial sensors are impractical for this purpose. Only a large constellation of satellites can offer this.
It is also possible (and not very difficult) to design incandescent bulbs that will outlive their owners. In fact, the first mass produced light bulbs generally lasted 2,500+ hours. In the 1920s, the major bulb manufacturers formed the 'Pheobus Cartel' in Geneva and secretly colluded to limit the lifespan of bulbs to 1,000 hours to boost sales [1]. Another example of planned obsolescence harming consumers and the environment.

This is not necessarily true. Oil has a traditionally low elasticity of demand, meaning that demand for it does not change significantly even when its price changes. This is particularly true in the US, where there are few public transportation options in most cities.
Why is the converse not true as well? If one believes the constitution does not protect the right to individual privacy, then don't expect it.
What is the basis for this assessment? At least with a stock you can point to the underlying performance of the company. What factors affect BTC price other than sentiment?

I don't know what are the typical margins of victory for French Elections. In the 2000 US Presidential Election, George W. Bush won the Presidency by a margin of 537 votes in Florida. If the US had implemented French style balloting, a single attack of this kind in a heavily Republican district of Florida could have easily swayed the election to Gore.
So an attacker could potentially invalidate hundreds (or thousands) of votes by stuffing a single fake ballot into the box? This seems like the illusion of security.

Yes, in my opinion a 10% difference is significant. The source in no way contradicts that. If you believe 10% is not significant, that's just your opinion as well.
The US is expected to spend a total of $6T on COVID relief with the passage of the Biden Plan (around $4T was already spent under the Trump administration)[1]. It's debatable whether or not this spend 'worked' as intended.
Investing in carbon removal will create entirely new industries. Rather than paying people to stay at home, it will create skilled tech jobs for Americans. In terms of justification, emissions reductions alone won't stop climate change at this point. It will take centuries for natural processes alone to remove our historical greenhouse gas emissions [2].
