Fire:
• allowed the processing of materials - baking of clay to make pottery
• This pottery was then used as a storage for surplus grain which reduced the amount of time searching for food in shortages
• This time which was gained could be used making tools or weaving clothes
• It could also be used to clear woodland for farmland quickly or move animals

Animals:
• They replaced humans in ploughing, carrying goods and driving machinery
• This gives them more time

Wind and water power:
• These were used to drive machinery for grinding, spinning and weaving
• Wind power could be used to propel ships and pump water
• Wind power also allowed sailing so this allowed countries to trade

Smelting:
• Smelting of metals using wood and charcoal allowed useful items to be made - cutting blades, nails, wheel rims and plough
• Smelting of steel was created using coal and coke - this created sophisticated machinery - steam engines
• Coal could be transported wherever it was needed

Crude oil:
• This has increased the amount of energy available - almost all tasks performed more easily

Electricity:
• This can be used to drive more equipment than could be driven by just primary energy
