NOTE

PETROLEUM

Renewable energy is energy that has been derived from earth’s natural resources that are not finite or exhaustible, such as wind and sunlight. Renewable energy is an alternative to the traditional energy that relies on fossil fuels, and it tends to be much less harmful to the environment.

 

Renewable energy sources

Solar, Wind, Hydroelectric, Geothermal, Ocean, Hydrogen, Biomass

 

Hydrogen as a potential future fuel

Hydrogen energy involves the use of hydrogen and/or hydrogen-containing compounds to generate energy to be supplied to all practical uses needed with high energy efficiency, overwhelming environmental and social benefits, as well as economic competitiveness

 

Fuel cells

  • In a fuel cell there are two electrodes, usually platinum, in an electrolyte and the reactants are continually being supplied to the electrodes. This type of cell can supply electrical energy continuously.
  • When hydrogen react with oxygen to form water in a fuel cell, electrical energy is produced
  • Fuel cells prove a potable convenient source of power. Hydrogen fuel cells are used in space to provide the electrical power for space shuttles and other space vehicles

 

EVALUATION:    1. Define renewable energy

  1. Give three examples of renewable energy
  2. Discuss hydrogen as a potential future fuel
  3. Explain fuel cells

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the students positively
