Study Notes
Energy Sources Throughout History
Pre-History (Before 3000 BCE)
- Primary energy sources:
- Human and animal power
- Biomass (wood, plants)
- Water (rivers, streams)
- Limited energy needs, mainly for basic survival and tool-making
Ancient Civilizations (3000 BCE - 500 CE)
- Energy sources:
- Biomass (wood, charcoal)
- Animal power (domesticated animals)
- Water power (waterwheels, mills)
- Human power (slaves, manual labor)
- Development of early energy technologies:
- Fire for cooking, heating, and metalworking
- Waterwheels for grain milling and irrigation
Medieval Period (500 - 1500 CE)
- Energy sources:
- Biomass (wood, charcoal)
- Animal power (horses, oxen)
- Water power (waterwheels, mills)
- Human power (manual labor)
- Introduction of new energy technologies:
- Windmills for grain milling and pumping water
- Horse-powered machinery
Industrial Revolution (1500 - 1800 CE)
- Energy sources:
- Coal
- Water power (hydroelectricity)
- Steam power (coal-fired engines)
- Development of new energy technologies:
- Steam engines (James Watt, 1769)
- Coal-fired power plants
Modern Era (1800 - 2000 CE)
- Energy sources:
- Fossil fuels (coal, oil, natural gas)
- Nuclear power
- Hydroelectric power
- Renewable energy (solar, wind, geothermal)
- Development of new energy technologies:
- Internal combustion engines (1870s)
- Electricity generation and transmission (1880s)
- Nuclear power plants (1950s)
Contemporary Era (2000 CE - present)
- Energy sources:
- Fossil fuels (coal, oil, natural gas)
- Renewable energy (solar, wind, hydro, geothermal)
- Nuclear power
- Alternative energy (hydrogen, biofuels)
- Focus on:
- Energy efficiency and conservation
- Sustainable energy development
- Reducing greenhouse gas emissions and climate change
