An agricultural facility harvests wood chips from fast-growing willow trees to burn as fuel in a biomass power plant.
State and explain whether this energy resource is renewable.
The power plant uses some of its waste thermal energy to heat a community swimming pool located some distance away. State one problem of using waste energy in this way if the power plant is far from the swimming pool, and suggest a way of reducing this problem.
State two environmental consequences of burning fuel oil (a fossil fuel) instead of biomass to generate electricity.
