A farmer plans to generate all the electricity needed on her arm, using either a biogas generator or a small wind turbine.
The biogas generator would burn methane gas. The methane gas would come from rotting the animal waste produced on the farm. When burnt, methane produces carbon dioxide.
The biogas generator would cost £18,000 to buy and install. The wind turbine would cost £25,000 to buy and install.
The average power output from the wind turbine would be the same as the continuous output from the biogas generator.
Evaluate the advantages and disadvantages of the two methods of generating electricity.
Conclude, with a reason, which system would be better for the farmer to buy and install.
