WIND DISADVANTAGES

DISADVANTAGES

• Not always available... The wind must blow first!
• $1.3- $2.2 million to build wind farms
• Gives off pollution when making the turbines
• Killed 976 million birds so far
• Need to have a large area; takes up space

DISADVANTAGES

• The blades of the turbine can fly off after a long period of time
• Some people consider them an eyesore
• Is inefficient and doesn't produce high volume of energy
• Disturbs wildlife
• Very noisy

ENERGY SOURCES

BIOMASS

ADVANTAGES

• It's renewable
• Made from plants
• No pollution
• Gives off energy

DISADVANTAGES

• It's limited
• Very time consuming
• In some cases, major causes of pollution
• Expensive production
• Needs work in harvesting

ADVANTAGES

• Doesn't produce waste
• No pollution
• Free wind
• Environment friendly

FOSSIL FULES

ADVANTAGES

• Cheapest energy source
• Most reliable energy source
• Large supplies are still available
• Help make everyday objects
• Mast safe source

DISAVANTAGES

• Major pollution
• Not renewable
• Takes a long time to make
• Makes acid rain
• Gives off carbon and sulfur dioxide

GEOTHERMAL

ADVANTAGES

• It's renewable
• Saves a lot of money for heat
• Creates generators
• No pollution

DISADVANTAGES

• Can only be built where hot water is
• Very expensive to drill
• Supplies less than 1% of our needs
• Hazardous materials
• Need for infrastructure

HYDROPOWER

ADVANTAGES

• Cheap energy source once built
• No pollution or globle warming
• Works in very large scale
• This energy can be stored
• Supply can adapt quickly

DISADVANTAGES

• Can hurt the environment
• Building a dam is expensive
• Not many places are suitable for dams
• People can loose their home
• Reservoirs can fill with silt and become useless

NUCLEAR POWER

ADVANTAGES

• No pollution
• Small amount of fuel needed
• Produces small waste
• Produces a lot of energy

DISADVANTAGES

• Core produces radiation and radioactive waste
• Natural U-235 very rare must be made by humans
• Is very expensive for nuclear reactors
• Nuclear waste remains dangerous for a long time
• Power plant life span is limited

SOLAR

ADVANTAGES

• Unlimited supply in hot regions
• Clean energy
• Renewable
• Silent
• Many possibilities for the future

DISADVANTAGES

• Limited supply on cooler areas
• Some power plants need large areas
• Depends on weather patterns
• Doesn't work at night
• Systems can be exspisive
