How is electricity distributed across the UK? | Via the National Grid |
How does the national grid work? | Electrical energy is taken from power stations to where it's needed in homes and industry. In order to keep energy efficiency high, the voltage is boosted to a huge amount, whilst the current is very low |
What two things are needed, so the National grid can keep voltage high, with current low? | Transformer and Pylons |
What are the two transformers used for? | One is used so it can step up the voltage to a huge amount, whilst the step down transformer is used to bring it down to a safe level |
What are the two ways electricity can be transported? | Either through underground cables, or over head pylons |
Give three pros of using over head cables, rather than underground cables | 1) Lower set up cost 2) Easy to access and fix 3) Easy to set up |
Give three pros for using underground cables, opposed to overhead pylons | 1) Minimal maintenance is required 2) It is hidden from the public 3) It's not affected by weather |
In the future, how will supply be increased? | By opening more power plants or increasing their power output |
How can electricity demand be reduced? | By having consumers purchase more electrically efficient products |
