• Solar panels do not generate electricity, but rather they heat up water. They are often located on the roofs of buildings where they can receive heat energy from the Sun.
• Wind turbines convert kinetic energy into electrical energy by using wind power. The blades rotate when there is sufficient wind speed and this motion drives an electric generator.
• Geothermal energy involves drilling deep underground to extract hot water and steam. It then passes through pipes to drive turbines and produce electricity.
• Hydroelectricity uses moving water to turn turbine blades connected to generators. This generates electricity as it moves through dams or rivers.

She reveals to Mrs Johnstone that they are unable to have children and her husband refuses to adopt. Mrs Lyons’ desperation leads to her manipulating Mrs Johnstone into giving her one of the twins.
• As Edward grows up, Mrs Lyons is overprotective and jealous. She gives her son very little freedom and becomes paranoid when she learns that he is spending time with his biological family. This actually leads to Edward becoming more distant from her, as he finds her suffocating.
