Study Notes

  • Clean energy sources are vital due to the negative impacts of non-renewable energy.
  • Modern and nanotechnology are key players in producing clean energy, addressing climate change, and achieving energy sustainability.

Modern Technology Applications in Clean Energy Production

  • Advanced solar energy techniques are used

Concentrated Solar Power (CSP)

  • CSP plants store thermal energy to address periods of low solar cell efficiency (e.g., cloudy periods, before sunrise, after sunset).
  • CSP technology makes solar energy a continuous and efficient source for electricity, compared to solar cells and fossil fuel plants.

The process of a Concentrated Solar Power Plant

  • Mirrors or lenses focus sunlight onto receivers, which direct the energy to a network of pipes containing water.
  • Continuous heating raises water temperature, turning it into steam, which drives turbines connected to electric generators.
  • Turbine rotation from steam pressure transfers motion to generators, converting kinetic energy to electrical energy.
  • Heat can be directly used in factories that rely on thermal energy in their processes.
  • Thermal energy is stored in insulated cylinders containing molten salt, allowing for daily and extended reuse.

Analysis of Technological Innovation Applications

  • Research recent tech innovations in clean energy production, like nanotechnology and biotechnology.
  • Explore how these can address climate change challenges
