Which of these statements about biomass energy is false?

Points: 1

1. Today, biomass makes up only a small percentage of total world energy use. However, for approximately 2.5 billion people, biomass energy remains the primary source of energy for cooking and heating.
2. Biomass energy can be produced by converting the feedstock into a combustible gas mixture called syngas. The syngas can then be used in place of natural gas for heating electricity and other uses.
3. Biomass energy can be produced from the process of pyrolysis. Pyrolysis is the process of heating feedstock at high temperatures in the absence of oxygen. Since no oxygen is present, the organic material does not combust. Instead, the chemical compounds decompose into three forms: a liquid called bio-flow, a solid called bio-char and a syngas.
4. Biomass energy is produced using feedstock. The feedstock is converted to energy by several means. A common biomass conversion process includes combustion where feedstock is burned in the presence of air to release heat.
5. Biomass energy or bioenergy refers to energy produced from organic matter. Biomass is primarily found in the form of living or recently living plants.
