Apes Energy

According to the second law of thermodynamics, whenever one form of energy is transformed into another,

• all of the energy is put to work

• all of the energy is converted into a less usable form, like heat

• some of the energy is converted to a less usable form, like heat

• 50% of the energy is put to work, the rest is lost as heat

Which type of fuel produces the most sulfur?

• wind

• coal

• biomass

• nuclear fission

How does biomass reduce our carbon footprint by producing less CO2 than fossil fuels?

• Plants absorb the same amount of CO2 that is released when it is burned.

• Plants remove CO2 from the atmosphere and put it permanently into the ground.

• Biomass filters CO2 to make it more environmentally stable.

• Biomass doesn't release any CO2 when burned.
