Macrogeneration

Question 1

How is electricy produced by a turbine

Answer 1

Convection current in the air is caused by the suns heating of the earth
Each air particle adds a samll force on the blade of the turbine
Inside the turbine electricity is produced which cam be used locally or in the national grid

Question 2

Traditional fossil fuel power plant energy creation

Answer 2

Fuel gets combusted in the furnace to release the chemical energy (thermal)
The thermal energy increases the heat of the water in the furnace
Water evaporates at 100°C
Steam enters turbine with loads of energy and collides with the fins of the turbine and loses energy
Hot steam enters cooling towers - losing energy and condenses into water then goes back into the furnace.

Question 3

How efficient is the fossil fuel power plant

Answer 3

40% efficient

Question 4

Traditional power plant - label

Answer 4

See page/ book

Question 5

Direct renewable energy source

Answer 5

These renewable energies take energy from a renewable source such as wind or waves in the ocean and can convert this into electrical energy directly

Question 6

Direct renewable energy sources examples

Answer 6

Wind
Hydroelectric
Wave
Tidal

Question 7

Indirect renewable energy source

Answer 7

These take energy from a renewable source such as the sun using a physical characteristic of the material being used, and convert this energy into electrical energy.

Question 8

What does macrogeneration mean

Answer 8

Large scale electrical generation
