I hope you all celebrated Dogs Day in style this week. I certainly did…
This week in my blog I am going to be looking at solar energy, and in particular wind turbines. This is because I have noticed more and more turbines popping up, and there have been lots of stories about wind farms being built off the coast of Britain! Aunty Jules says she sees them on her journeys quite often and lots of children always ask what they are and how they work!
They use the kinetic energy (that means movement energy) of the wind which turns the blades of the turbine and transfers this energy to a generator which is housed in the centre of the turbine. Of course, this is me making it all much simpler for us all to understand… it is much more complicated than that.
The wind is produced because of convection currents in the Earth’s atmosphere, which are driven by heat energy from the Sun. As a result of this, the kinetic energy in wind is a renewable resource which is great because it means as long as the Sun is there, we will have it! However, some people don’t like wind turbines because they can be considered an eye sore and when they turn they can be noisy.
My fiend Ellie told me that where she works at Glyndebourne, they have their very own wind turbine. It produces enough power to provide 95% of the energy for Glyndebourne Opera House, which is amazing when you think of all of the energy used in one show alone! Lighting rigs are not cheap to run!
Because of the need to have wind, you find wind turbines in windy places. That is why people want to build them out at sea. I always notice how windy it is down at the beach! This is good too because you can’t see or hear them as much.
Do you have any wind turbines or maybe solar panels near you? I’d love to see some photos of just how HUGE they are! If you’d like to know more about the science behind the turbines, you can take a look here.
Until next time fiends,
