hydroelectricity

• hydroelectricity has a power output that is

  medium

  
• Hydroelectricity is

  renewable

  
• what store of energy does hydroelectricity use

  gravitational potential

  
• hydroelectricity is used for generating

  electricity

  
• a reservoir is a

• what do we use to generate electricity

  the difference in water levels

  
• list an advantage of using tidal and hydroelectricity

  produces electricity without pollution

  
• hydroelectricity is a

  reliable source of energy

  
• the advantage of having reliable energy sources is that it can

  provide an immediate source to increased energy demand

  
• tidal energy has fairly low

  running costs

  
• tidal and hydroelectricity can both work on

  large and small scales
