By that logic, all of the Earth and the moon were once parts of stars, so tidal and geothermal are also solar.

When people say "solar energy", they are usually referring to first order solar energy, directly from photons, not second or third order solar energy after it has been trapped into other sources of potential energy.

If it's not our sun then it isn't solar.

Probably neutron star collisions, actually.

Pricing fossil fuel pollution at zero is the biggest subsidy in the world bar none. Contrast this with for example nuclear power, where potential pollution risks as well as storage of its spent resources are some of the biggest costs. If they were subsidized equally to fossil fuels, the costs of those would be very low, with the public simply paying the price for any negative health effects.

Oil is directly subsidized in most oil producing countries. Go look at what fuel costs in Saudi Arabia or Nigeria, vs what they could sell it for on international markets. That's a subsidy.

Jet fuel is universally exempt from tax. Try finding any other energy source that is.

The US oil subsidy currently is projected to increase the Pentagon budget from one trillion to one and half. I bet one could build a lot of solar panels for 500 billion dollars, and you can use them more than once, too.
