DISADVANTAGES OF HYDROPOWER

• Building dams displaces people and animals
• Can cause mudslides
• Changing the river pathway and shortage of water can cause serious disputes between people
• Dams are extremely expensive to built and must be bto a very high standard
• The high cost of dam construction means that they must operate for many decades to become profitable

Untitled Slide

• The turbines of the dams can kill many fish
• Releases a large amount of carbon dioxide and methane
• The formation of large and huge dams destroys the living around them
• As the hydroelectric power is produced by the water which depends on yearly rainfalls
• People living in in villages and towns that are in the valley to be flooded, must move out

ENERGY SOURCES

HYDROPOWER

ADVANTAGES OF HYDROPOWER

• Supplies about 20% of the world electricity
• Clean & renewable
• A constant source of energy
• Really saving natural resources

WIND ENERGY

ADVANTAGES OF WIND ENERGY

• Non-polluting energy source
• Does not cause green house gases
• With modern technology, wind could be captured efficiently
• Wind is free

DISADVANTAGES OF WIND ENERGY

• Cannot be stored easily
• Hard to move over long distances
• Its noise disturbance
• The turbines are ugly

SOLAR ENERGY

ADVANTAGES OF SOLAR ENRGY

• We will never run out of it
• Can save money on energy bills
• Can also save money on taxes
• Don't pollute, once set up

DISADVANTAGES OF SOLAR ENERGY

• Can be expensive
• Does not work in the dark
• In unreliable climate, solar energy is also unreliable as a source of energy
• Produce some pollution

NUCLEAR POWER

ADVANTAGES OF NUCLEAR POWER

• Produces no greenhouse gases
• Such a powerful source of energy
• Can't become thermonuclear bombs
• It is reliable

DISADVANTAGES OF NUCLEAR POWER

• The waste it produces is highly radioactive
• There are nuclear accidents
• It is non-renewable
• Major impact on human life

GEOTHERMAL ENERGY

ADVANTAGES OF GEOTHERMAL ENEGY

• Reduce reliance of fossil fuels
• Significant cost saving
• Is renewable
• Does not hurt the environment

DISADVANTAGES OF GEOTHERMAL ENERGY

• It is expensive
• It's not a widespread source of energy
• Can run out of steam
• May release harmful gases
• Not easily transported

FOSSIL FUELS

ADVANTAGES OF FOSSIL FUELS

• Easily availability
• They produce a large amount of energy
• High calorific value
• Easy set up
• Easy transportation

DISADVANTAGES OF FOSSIL FUELS

• Send smoke into air when burned
• They pollute
• Hurts plants and animals
• Human health gets affected
• Oil spills makes gooey mess

BIOMASS

ADVANTAGES OF BIOMASS

• Not expensive
• Renewable resource
• No harmful emissions
• Clean energy
• They reduce landfilss

DISADVANTAGES OF BIOMASS

• Pollution
• Global warming
• Increases greenhouse gases
• Harmful to environment
• They consume more fuel

DISADVANTAGES OF HYDROPOWER
