Yet Another Reason Why Wind And Solar Electricity Generation Will Never Work To Run An Economy

Our power grids are built around alternating current, that is current that varies in a regular sine wave pattern over time . . . . Voltage also varies in the same way. This electricity is generated utilising some fundamental principles of physics. If you rotate one magnet inside the magnetic field of another magnet you can induce a current in a wire. In our power grids, this happens in conventional power stations.
