  The point when global petroleum production reaches its maximum rate
• What happens during fission?


  A heavy atomic nucleus splits into smaller nuclei
• What is released during the fission process?


  A significant amount of energy
• What are the main types of energy sources discussed in Unit 6?

  • Non-renewable energy sources: Electricity, Coal, Petroleum, Natural Gas, Nuclear Fission
  • Renewable energy sources: Solar Panel, Biofuel, Geothermal, Hydroelectric Power, Biomass
• What are the strengths and weaknesses of different energy sources mentioned in Unit 6?


  Strengths:

  • Renewable sources are sustainable
  • Non-renewable sources are often more energy-dense

  
  

  Weaknesses:

  • Non-renewable sources produce waste and pollution
  • Renewable sources may require significant space or resources
• What is a characteristic of Cortes in terms of cost and efficiency?


  It has a minimum initial cost but higher per unit costs.
• What is the role of a net product in a reaction according to the study material?


  A net product is used in a reaction to create low risks of matter.
• What are the key features of bioreactors?


  • One of three areas to maximize efficiency
  • Mostly multipurpose
  • Intense pressure during operation
  • Attracts fuel to enter or slightly outside
  • Prevents excessive consumption of matter
  • High-boiling point reacts more slowly
  • Consumes less energy
• How does the pressure in bioreactors affect their efficiency?


  The pressure should be intense to maximize efficiency.
• What is a characteristic of thermochromic materials?


  They compress into a smaller phase and may be slightly brittle or have cracks.
• What materials are suggested for use in thermochromic construction?


  Copper parts with core materials are suggested.
• What are the advantages of thermochromic materials?


  • High purity of matter construction
  • Practical in supporting design
  • Efficient with higher heat slowly
  • Versatile with wider potential
  • Returns high energy densities
• What is the potential of thermonuclear energy in design?


  It has high potential in a supporting design.
• What is a characteristic of beagarthric energy?


  It is derived from a source that regenerates over time.
• What is the nature of peminean bioreactors?


  It is a carbon neutral bioreactor.
• What is the process of a runaway flame?


  It produces energy from a source but uses oxygen as a byproduct.
• What are fossil fuels formed from?


  They are formed from the decomposition of buried carbon with minerals.
• What is CO2 removal?


  It is the process of removing greenhouse gases from the atmosphere.
• What is ethanol?


  Ethanol is a renewable, liquid biofuel produced through fermentation of plant sugars.
• What is biodiesel made from?


  Biodiesel is manufactured from vegetable oils, refined fats, or recycled animal grease.
• Hydropower, also known as hydroelectric power, is generated by capturing the energy from moving water to produce electricity.
• (n) energy conservation - the practice of using less energy to save money or reduce pollution
