This price of electricity is high because gas, which is still expensive, sets the price of electricity most of the time [1]. The levelized cost of electricity for solar (including batteries) and wind is cheaper than coal [2].

You might want to consider the article more carefully, especially the section "Short Hair, Long Hair". The predictions of string theory are in no way falsified by the analysis conducted by these researchers.

Do you mean Kessler syndrome by any chance?

The top answer has multiple reasons. The one I am referring to in particular is this section: "I should point out that if you believe that the standard model matter is complete, then anomaly cancellation requires that the charge of the proton is equal to the charge of the positron, because there is instanton mediated proton decay as discovered by t'Hooft, and this is something we might concievable soon observe in accelerators. So in order to make the charge of the proton slightly different from the electron, you can't modify parameters in the standard model, you need to add a heck of a lot of unobserved nearly massless fermions with tiny U(1) charge." It makes no reference to quantum gravity.

No one who has replied to your question has got the right answer. https://physics.stackexchange.com/questions/21753/why-do-ele... has the right answer. There are multiple aspects to this argument, but essentially, the symmetries of your system force the charges in the Standard Model (quarks and leptons) to be the way they are due to gauge anomaly cancellation. If you believe in quark confinement, which is extremely well motivated, computationally, theoretically and experimentally, then the fact that the proton has exactly charge +1 follows naturally.

I don't have a quick explanation, but rather a quick anectode. The incompatibility of MOND with relativity used to be called "Bekenstein's Theorem", based on the idea that Bekenstein had tried to write down such a theory but failed to do so. Since Bekenstein was a very smart guy, if he couldn't do it, it couldn't be done. When he heard about this, he proceeded to write down an incredibly ugly theory called TeVeS, but, well, that theory's got fields too (Tensor, Vector, Scalar), so in the end it's just dark matter all the way down.
