Pollution
Which type of energy sources create the most pollution?
Fossil fuels such as coal, oil and natural gas create the most pollution.
Which types of energy are renewable? Nonrenewable?
Biofuel, Geothermal, Hydropower, Wind and Solar are renewable. Nuclear energy,coal,oil and natural gas are non renewable
Compare and contrast wind and solar energy.
Wind energy and solar energy are dependent on the weather. Solar energy uses the sun but wind turbine uses a generator powered by wind.
How can the burning of fossil fuels have a negative impact on human health?
Name 2 advantages to solar energy
Renewable.
Low maintenance cost.
Reduces electric bills.
How will building a hydroelectric power plant affect the environment?
Building a hydroelectric power plant will affect the environment negatively and it will cause fish to die and harm rivers.
Why will we need to use more renewable resources in the future?
Compare and contrast nuclear energy and biofuel
Nuclear energy and biofuel both are reliable sources.
Nuclear is nonrenewable but biofuel is renewable.
What gases are released into the air from burning fossil fuels?
Carbon Dioxide, Methane.
Name 2 advantages to nuclear energy
Creates lots of energy.
Low impact on the environment.
How does mining coal affect the environment?
Mining coal affects the environment negatively because it destroys trees, clears topsoil and natural wildlife habitats.
What is conservation? How can we conserve fossil fuels?
Compare and contrast hydropower and geothermal energy.
Hydropower and Geothermal are renewable.
Hydropower is dependent on the weather unlike Geothermal.
What is a disadvantage to using nuclear power?
It creates radioactive waste
Name 2 advantages to wind energy
Renewable.
No pollution.
Wind turbines can be built on existing farms or ranches.
Creates jobs.
What effect does excess carbon dioxide have on the environment?
Excess Carbon dioxide has a negative affect on the environment because it contributes to global warming.
Name a good way to conserve energy.
A good way to conserve energy is by turning off the lights or using ethanol fuel instead of the gas you usually use.
Compare and Contrast wind turbines and hydropower turbines.
Wind turbines and Hydropower are both renewable. Wind turbines do not harm many animals and can be built on farms unlike hydropower plants.
What are two disadvantages to drilling for oil in the ocean?
Deadly to animals.
Destroys habitats.
Dangerous gas.
Name 2 advantages to biofuels.
Renewable.
Cost efficient.
Reduce harmful gases.
More economic benefits.
Do wind turbines create pollution?
No, Wind turbines do not create pollution
Does using wind turbines instead of oil conserve fossil fuels?
Yes, Wind energy is renewable unlike Oil.
Compare and contrast hydropower and geothermal.
They both are renewable
Hydropower uses water but geothermal uses the earth.
How is the efficiency of a wind turbine affected by its location?
The more wind there is in a specific location the more energy. If there isn't much energy then there won't be much energy.
Name 2 advantages to geothermal energy.
Geothermal is renewable.
Geothermal is clean.
Little maintenance.
Reliable.
High efficiency
