Give odd one out. Give reasons for your choice :-

1. Solar cell , windmill,thermal power station ,biogas plant, solar cooker

2. Wind energy , hydroenergy,tidal energy,geothermal energy

Dear mate, 
1) I think it should be Biogas plant because biogas is mixture of gasses to break down, organic matter
whereas others are producing energy
2)geothermal energy because it produces heat energy which is stored in earth whereas others produce electricity
