Understanding Energy: Forms, Sources, and Consumption Patterns

Energy exists in various forms such as heat, light, mechanical power, and electricity. The nature of energy sources divides them into exhaustible (like fossil fuels and nuclear energy) and renewable sources (like solar, wind, and wave energy) that replenish daily. Energy development is directly correlated to consumption; as the world demands more energy, consumption rates increase significantly. Historical insights reveal energy use has escalated from 3 kWh for cave men to over 410 kWh in the 21st century. Understanding these dynamics is vital for sustainable energy planning.

  2. From of energy • Energy has many interchangeable forms viz. • Heat • Light • Mechanical power • electricity

  3. NATURE OF ENERGY SOURCES • Some sources like fossil fuels on which the present they world depends the most are exhaustible. Similar are nuclear and energy . • Some sources are renewable-they rebirth everyday . • Solar wind wave .

  4. DEVELOMENT VSCONSUMPTION • Development is direct to the of energy. • The more you are more is the energy . • World primary energy demand. • 1972 :270 ej (1018 j) • 1985:390 ej • 2000:590 ej • 2020:840 ej

  5. SOURCES OF ENERGY • There are many sours of energy • Fossil fuels coal, oil and Nature gas • Biomass Energy ,energy from plants • Hydro power • Nuclear power

  6. Energy consumption • Cave Man (10,00,000)years ago 3kWh • Hunting man (1,00,000 years ago) 7kwh • Agricultural man (5000BC) 13kwh • Industrial man (20th century) 260kwh • advanced Technically man • (21stcentury) 410kwh++
