Imagine you’ve got a massive factory making video game consoles… It’s the size of a football pitch and the machines have to run 24 hours a day to make enough consoles for all the orders!
Now, how big do you think their electricity bill would be?
Power is needed to make the machinery work and workers need lighting and heat in order to do their jobs safely. An energy engineer might help the factory owner to come up with ways to use less energy and keep costs down.
Engineers might be able to suggest using light fittings that are more energy efficient in winter, and insulating the factory so that less heat escapes too.
They could have sensors on the lights so that they turn off in areas when people aren’t there.
Energy engineers need to understand about all types of energy and how machines and buildings use it.
They’ll be taking measurements of items, or places, and using computer programmes to figure out what changes could be made to improve the energy efficiency.
Another type of energy engineers will be working on is improving and finding new ways to create power.
Windmills or wind turbines are becoming a very popular way to generate electricity and cause less harm to the environment than fossil fuels.
Now, whilst the biggest ones in the UK are about two hundred feet high, scientists in America are working to create one that’s over sixteen hundred feet high. That’s half a kilometre!
The larger a turbine is, the more powerful and efficient it is, and so the thinking is that bigger will definitely be better.
New technology is needed to make the blades both strong and able to bend in the strong winds you find out at sea.
