Chance to discuss is always a good thing.
The sun is not within Earth, it emits all heat and energy regardless of how much we do with it or not, the same amount of it falls on Earth every day, 24 hours worth more photons.
We can choose to convert some of those to things other than heat or not.
The algebra oven you mention, when solar powered, is taking some of the solar energy/heat which would otherwise heat the Earth, from some solar panels.
An oven creating things converts some of the heat energy to matter, or in the case of the algebra oven; information.
So the net result of using the solar energy is reduction of heat emission normally occuring every day, by absorption of energy by sunlight.
So using the energy of the sun makes Earth cooler, not hotter.
Converting sunlight to other things than heat, removes the heat from sunlight, it is not possible to create heat, or add any more heat to sunlight than it contains already, only convert to matter, information, or other form of energy like electricity. All of those conversion processes of sunlight reduce heat.
Remember, E = M x C squared, Mr scientist!
Thinking otherwise is the reason our planet is now burning, because we do not use the sun, we use stored energy from Earth, which was put there in the first place by the cooling process of creating all things on Earth, from sunlight.
Effectively, Earth bound generation of electricity from fuels is a process of uncreation. Matter, which was created by solar energy in the first place, is converted to heat in the combustion process.
So generating electricity from fuels elevates the temperature of Earth, whilst generation of electricity from solar cools Earth.
Elevating the temperature of Earth results in increased frequency of natural combustion, there we see a runaway effect.
Less creation, or uncreation makes more heat, more creation makes less heat, from the energy. All energy, from all things and for all things comes from the sun, get it?
It isn’t all about us, or even all about us and our planet, it is all about us, our planet, and the sun.
All other life on Earth creates things, which reduce the heating effect of the sun on Earth.
Life is about creation, which is about reducing heat, not increasing it.
We exist to create things.
When we try to create from the wrong source, the opposite effect is what is achieved, we destroy.
We have yet to begin truly creating, except perhaps with the case of Bitcoin, which might financially fuel many things, more creation, from sunlight.
If, or when we do, the net effect will be maintenance of Earth at the roughly constant temperature we need to survive, despite every day having Trillions more coulombs of energy falling on Earth from the sun.
To survive, we just need to get busy creating, truly creating, with the energy of sunlight.
It isn’t really much more complicated than that.
We just need to get a little more busy livin’ instead of being so busy dyin’.
As long as we are using money to represent and exchange capital of Earth, all of which was created from the energy of the sun, long ago, we are busy dyin’
When we get busy with money representing the live energy of the sun, we will be busy livin’.
