We know that when biomass decomposes a biproduct of that decomposition is heat. The heat generated from compost (or decomposing biomass) can be enough to start fires. That’s why they say don’t get straw bales wet. Not only do strawbales breed microorganisms/mold (bacteria and fungi) the microorganisms create heat through the decomposition process. This heat can be hot enough to ignite strawbales on fire. Many a barn have burned to the ground because of this.
Now… If you could capture that heat, it can be used for multiple purposes if stored and used efficiently. One such use is producing electricity through thermo electric modules. (you can also heat your greenhouse with compost as well)

“…Can We Charge Batteries With Compost?
It had been found previously in lab replications that it is possible to charge batteries
using the waste energy from a compost pile using thermoelectric modules. In this
project, ways of improving the e±ciency of this process were explored. The use of a
copper slab insulated with extruded polystyrene would transfer 86% § 2% from the
center of a pile, where it is the hottest, to the outside, where a charger would be.
This is a signi¯cant percentage, but a larger percentage is desired because a large
temperature di®erence across the module means a larger power output.
The power output of a module increases with increasing temperature, and at a
±C temperature di®erence one undamaged module can produce 463 mW §6
mW at matched load. This amount of power is able to charge a battery slowly, but
more modules or a bigger module would be needed for faster charging…”

“…Thermoelectric modules are able to take the temperature difference between
hot compost and cold air and turn it into electrical current…”

You can also heat your water with compost
Technically this is a very simple design that just about anyone can build themselves. We know the compost produces heat as a biproduct of decomposition. As such, this is just one of a myriad of ways we can capture heat, and use it to generate electricity and heat your home. Heat is energy, and heat is what powers our military Aircraft Carriers. They use nuclear reactors to power the ships, but it’s only to produce heat. Heat is used to generate electricity. Coal power plants also use heat to produce electricity.
Compost is MUCH cleaner than coal power, and doesn;t pollute the atmosphere. Compost is also much safer than nuclear energy. If you have a nuclear meltdown or spill nuclear waste, what happens. It poisons everything.
If you have a compost spill, guess what happens?
