Classic reddit answer... Incorrect, just to give the eye roll/wink to fellow redditors with hate boners for corporations

Here's a great video about an LA underground power line. It goes over many of the downsides of underground power lines.
TL;DR
- The lines need to be insulated from each other. Above ground, they can just be hung far away from each other. Under ground, you need to spend more money either building a large tunnel or adding insulation.
- Locating where underground lines have been damaged is a pain in the ass (more expensive and longer down time).
- Digging up the lines to do the repairs is also a pain in the ass (again more expensive and longer down time).
- Just doing maintenance is a pain in the ass. So underground lines won't have trees falling on them, but they'll just fail because it's not worth doing preventative repairs and maintenance.

geography is a huge factor too, Cities are often built on poor soil or solid rock or flood areas or otherwise not viable extra costly

For context the US covers more than twice the area of the European union and has about 3/4 the population. The majority of countries in Europe are smaller than individual states in the US.

As a someone from a European country, when red has been part of Christmas imagery before Pemberton´s grandparents were even born, no. Both red, green and gold are all related to christian imagery. It has nothing to do with Coca-Cola.

Yes, all colours make an appearance of some sort in some holiday tradition. Appearance of widespread red is Coca-Cola's doing.

Use of red predates Coca-Cola by like 10 centuries. Coca-Cola popularized the exact image of Santa that exist right now, but they didnt come up with it, they just picked one that was good for their brand. Same with using red as a symbol of Christmas.

Yeah, to my knowledge, Coca Cola designed Santa’s suit and whole look in general.

Green comes from the norther European traditions of decorating with evergreens for the midwinter festival, presumably because of the association with the rebirth of spring. Red probably because of colour contrast. But it’s noteworthy that when Christmas trees became popular in the U.K. and then the USA gold was the usual colour of ornaments.
So, like all things it evolves over time.

Until your $100 electric bill becomes $700, and you still have outages from damages, just different damages that can take even more time to repair. Everything about having them underground is more expensive.

Green is because life, plants and especially holly has been a staple of winter festival throughout history. Red because Coca-Cola is very very good at marketing, and ran a campaign where Santa wore red. Now, christmas is half-red.

A lot of modern construction does use underground lines because they are far more reliable overall. But they're also a lot more expensive and a lot harder to service when they do break, especially if they run under pavement or other manufactured ground cover. While today underground lines are feasible, power lines predate widespread availability of powered construction equipment, so the amount of digging required would have been prohibitive. Now the biggest reason we still use overhead lines is simply institutional inertia - it's what's already there. Replacing the entire grid would be cheaper long-term but has an enormous upfront cost and doing it piecemeal would require transitions from overhead to underground that introduce a whole bunch of engineering and safety issues. There are a lot of people who think we should make the transition anyway for the exact reasons you brought up, and in many countries underground lines are now standard.

Christmas celebrates the birth of Jesus Christ, the savior of the world.
Green represents the tree that would provide the wood for the cross that he was crucified on and red represents his blood that was shed to save us all from our sins.

Name a country with zero above ground power lines please.

A lot of cities run power lines underground. They are much more secure and difficult to break. However, they are more expensive to install. Additionally, in the rare event that they do break, they are much, much more difficult to repair.

Yes! This is the best answer here. It's known as "auto creep" or "idle creep" if anyone wants to read up about it.

Incorrect. The clitourious is what grows into a penis after a fetus has been androgenized. Cultures that remove the clit are removing the equivalent of cutting off a males penis. Several cultures practice this as said. You sir or madam don’t have a clue what you are talking about.

same for mopeds and motorcycles etc. The engine and transmission are connected in gear(drive) when two are linked and it's a matter of whether enough horsepower is being generated to move based on current RPM, if not enough or on a hill or carrying load all require more engine torque to get moving initially
