You know what? Fuck it. Let's pretend that plants violate thermodynamics and store all of the chemical energy they photosynthesize for billions of years.

https://en.wikipedia.org/wiki/Photosynthetic_efficiency
>5.4% net leaf efficiency.
So if you covered every square in h of the Earth you would still have 94.6% of the energy of the sun.

>Photosynthesis increases linearly with light intensity at low intensity, but at higher intensity this is no longer the case (see Photosynthesis-irradiance curve). Above about 10,000 lux or ~100 watts/square meter the rate no longer increases. Thus, most plants can only use ~10% of full mid-day sunlight intensity.[6] This dramatically reduces average achieved photosynthetic efficiency in fields compared to peak laboratory results.
Oh wait, that's more like 99.46% of the energy from the sun. And that's if all the land and sea were completely covered with photosynthetic mass. Even if photosynthesis worked the way you think it does, which it doesn't, photosynthetic efficiency is so low that it doesn't matter anyways.
