Bioenergy as a form of renewable energy comes from natural sources.

→ As a form of renewable energy, ________________________________ sources.

We can produce bioenergy from food waste, manure, and other organic substances.

→ Bioenergy ___________________________ food waste, manure, and other organic substances.

Bacteria break down these organic substances, and methane is released.

→ These ______________________________by bacteria, and methane is released.

We collect methane, and then use it to produce electricity and heat.

→ After ______________________________, it is used to produce electricity and heat.

We can also make methane into biomethane, called renewable natural gas (RNg).

→ Methane _________________________________, called renewable natural gas (RNg).

We can use renewable natural gas (RNg) as a vehicle fuel.

→ Renewable natural gas (RNg)______________________ used as a vehicle fuel.

We use bioenergy, and this limits the amount of methane released into the air.

→ Using ________________________ methane released into the air.

We can reduce our dependence on fossil fuels by using bioenergy.

→ Thanks __________________________, we can reduce our dependence on fossil fuels.

Black carbon traps sunlight and sends it back into the air as heat.

→ _____________________________, black carbon sends it back into the air as heat.

When fossil fuels are burnt for energy, they release CO2 and other greenhouse gases.

→ _____________________________, fossil fuels release CO2 and other greenhouse gases.
