ENERGY MATTERS

This overview explores the key distinctions between renewable and non-renewable energy sources. Renewable sources include wind, solar, wave, geothermal, and hydro, each harnessing natural processes for sustainable energy. In contrast, non-renewable sources rely on finite resources like coal, oil, and gas, formed from ancient organic materials. The process of energy transformation is illustrated through power stations and pumped storage systems, which convert chemical energy into electrical energy, optimizing electricity usage by storing energy during low demand and releasing it during peak periods.

Presentation Transcript

  1. ENERGY MATTERS Renewable energy sources include Wind,solar,wave, goethermal,hydro

  2. ENERGY MATTERS • Non Renewable Sources include • Coal , oil and gas

  3. ENERGY MATTERS • Coal – made from dead forest material • Gas and oil – made from dead sea creatures

  4. ENERGY MATTERS • Power stations • Coal , oil and gas – • Chemical energy to heat energy

  5. ENERGY MATTERS • Pumped Storage System • Potential energy at the top dam to kinetic • energy in pipes to electrical energy at bottom reservoir

  6. ENERGY MATTERS • Electricity sold at peak price. • Electrcity bought back at night at low price and used to pump water back up to the top dam.
