Renewable Energy

How many types of renewable energy are there?

→ There are 5 renewable energies. Such as solar, wind, hydroelectric, biomass, and geothermal power can provide energy without the planet-warming effects of fossil fuels.

 

Advantages

1.      Can be obtained for free. Sunshine, for example.

2.      A fuel supply that never runs out

3.      Zero carbon emissions

4.      New and renewable energy can always be used without worrying about the supply running out.

5.      Alternative energy sources are also known to be environmentally friendly because they do not produce waste that damages the environment.

6.      Geothermal:  it has huge potential, sustainable / stable , use the difference of temperature. 

 

Disadvantages

1.      It takes time to develop it into an effective and efficient energy.

2.      This energy is also difficult to store and transport widely because of its high price again.

3.      Depends on natural factors that cannot be predicted or regulated.

4.      The supporting technology is also not ready to be produced.

5.      Long drought: hydroelectric power plants will find it difficult to generate electricity because the water current is not as strong as usual.

6.      Solar cell: high initial installation cost.

7.      Geothermal : it can be disturbed by earthquake, Location restricted
