Coal Energy

Energy: summary

Energy is something that all living things require to live. We use energy with everyday things .We create energy with different tools so we can have things like cell phones, computers, etc. Energy is essential for our everyday lives."link"

"Coal is made into electricity with the help of a turbine and a generator. Firstly, coal is crushed to a fine dust and burnt. The heat from burning coal dust turns water into steam and the steam is used to turn the blades of the turbine. The turbine connects to the generator which converts the turbine's rotations (mechanical energy) into electricity. The water is then cooled so that it can be reused." -Ergon.com"link"

Coal energy isn't used as much as it was in the 1900's. 40% of the U.S's energy is from coal.We use coal for alot of things like trains, steel production, and electricity. Coal is a dangerous thing to mine and can be very costly.Even though you don't see many coal factories nowadays, there is still a good bit of coal usage. The U.S. uses about 20% of the world's coal, today."link"
