Which of the following best describes biomass energy?

Biomass energy refers to the process of using organic materials, such as plants, agricultural waste, or other biological materials, to produce energy. This can include growing plants specifically for energy production and then burning these biomass resources to release stored energy, which can be used for heating, electricity generation, or as biofuels. The essence of biomass energy lies in its reliance on renewable organic materials, which, unlike fossil fuels, can be replenished over relatively short timescales through regenerative agricultural practices.

The other options do not describe biomass energy as accurately. Wind energy involves harnessing wind power through turbines, which is a distinct energy source not related to organic materials. Solar energy focuses on capturing sunlight using solar panels, entirely separate from the combustion of biomass. Lastly, the extraction of oil pertains to fossil fuel energy sources, which are non-renewable and further disconnected from the concept of biomass energy. Thus, option C best encapsulates the characteristics of biomass energy.
