A country needs to build new power stations to provide electricity for homes and industry.
One type of power station is a biomass power station (which burns wood pellets).
Describe how the chemical energy stored in the biomass is used in a biomass power station to generate electrical energy.
Some people in the country argue against building a new biomass power station. They say that the power station is expensive and is not highly efficient.
Explain the meaning of not highly efficient in terms of energy.
Apart from cost and efficiency, give two other reasons for not building a biomass power station.
