18.1 Biomass & Geothermal Energy

What is biomass energy?

• any organic matter that can be used by burning wood and other plant life.

• Radiant energy emitted by the sun.

• a combustible black or dark brown rock consisting mainly of carbonized plant matter, found mainly in underground deposits and widely used as fuel.

• made by tapping into steam or hot water reservoirs underground; the heat is used to drive an electrical generator.

Is biomass energy a renewable energy source?

• Yes, always, because you can grow trees again.

• No, it's just like fossil fuels.

• It depends, only if the source is not overharvested.

• No, because manure is not renewable.

What is a primary drawback to using biomass as an energy source?

• It produces more sulfur dioxide emissions than coal.

• Access to biomass is variable depending on location.

• No waste materials can be used.

• Removing the crops or trees for burning deprives the soil of nutrients used to grow them, resulting in lowered soil fertility.

Which of these is an advantage to using algae for fuel?

• It uses only fresh water.

• It can only be grown in the ocean or a lakee.

• It can be grown in wastewater and can use CO₂ from smokestacks.

• It causes eutrophication.

Renewable energy resources produce less_____________ than fossil fuels.

• pollution

• energy

• wind

• light
