Could somebody possibly explain the different forms of generating electricity? For example, wind turbines....etc.....etc.

Yes of course what aspects would you like me to explain? How they work? Advantages, disadvantages?

I understand the advantages and disdvantages, is just the aspect of how the electricity is generated. I understand fully about the solar energy, it is just the other ones, like the wind turbines, the one to do with hydraulics (I think) etc. I did my core last year (y10) but I am retaking it. The main bit Ifailed was this in the Physics. I don't even remember doing it in class. + I'm the only one retaking it, so it's best I o ove my weak bits.
Thank you so much!!!!

Hiya, you don't need to know much about how they are generated for core science but here is a simple explanation of how each method is generated- it may be the one you already have in your textbook?
Wind turbines: the wind passing over the blades makes them rotate and drive a generator @ the top of the narrow tower.

Hydroelectric power: @ a hydroelectric power station water is collected in a reservoir @ the top of a hill. The water is allowed to flow downhill so gravitational potential energy is transferred to kinetic energy which turns turbines @ the bottom of the hill. In a pumped storage system @ times of low demand surplus electricity is used to pump the water back up the hill 2 the reservoir, storing the energy. Then @ times of high demand it can be released down the hill and fall through the turbines transferring the stored energy into electrical energy.

Wave power: Wave movement drives a floating turbine that turns a generator. The electricity is delivered to the national grid on shore by a cable.

Tidal power: If a barrage is built across a river estuary the water @ each high tide can be trapped behind it. When the water is released to fall down to the lower sea level @ low tide it drives turbines.

Hope this helps, I'm not sure how much detail/explanation you needed?

Have you done your core exam?? If so what grade did you get (if you don't mind me asking).
