Which of the following is a common type of renewable energy used in HVAC systems?

Biomass is indeed a type of renewable energy that can be used in HVAC systems. It refers to organic materials, such as plants, wood, and waste, that can be converted into energy. In HVAC applications, biomass can be utilized for heating purposes by burning it to produce heat or converting it to biofuels that can be used for heating systems. This method of utilizing renewable resources helps reduce dependency on fossil fuels, thus contributing to more sustainable energy practices.

Using biomass aligns with the principles of green energy, which prioritize sustainability and the reduction of greenhouse gas emissions. As the world shifts towards more eco-friendly energy sources in HVAC systems, biomass stands out due to its ability to utilize readily available organic resources while also contributing to waste reduction.

On the other hand, fossil fuels, nuclear energy, and geothermal energy, while significant in their own right, do not classify as renewable in the same context as biomass. Fossil fuels are limited resources, and their combustion results in greenhouse gases. Nuclear energy, while low in direct emissions, is not renewable due to the finite nature of uranium. Geothermal energy is indeed a form of renewable energy, but it specifically refers to heat derived from the Earth’s interior and isn't the correct focus in the context of
