4.2 Alternate energy sources

What are the advantages of using solar energy?

• Free and unlimited supply of energy

• Ability to create solar panels easily

• Inexpensive equipment

• Consistent energy source

What are the disadvantages of using solar energy?

• There is an unlimited supply of energy

• Energy is free

• It is expensive, and supplemental heating is need when solar energy is unavailable

• It provides less power than all the other sources of alternate energy

What earth materials do nuclear plants use to produce energy?

• Heat produces by fission of hydrogen atoms is used to heat water. Steam drives a turbine that turns to a generator to produce electricity.

• Steam causes uranium atoms to separate and create energy that is harnessed through copper wire to create electricity

• Nuclear power plants do not produce energy they simply package it and deliver it to businesses and households that are in thier area

• Heat produces by fission of uranium atoms is used to heat water. Steam drives a turbine that turns to a generator to produce electricity.

What are the advantages and drawbacks of hydroelectric power?

• it provides more energy than all the other sources of renewable energy but the locations are not always easy to create

• renewable but dams have a finite lifetime high water levels are needed

• low water levels are needed but they are not as renewable as the other sources

• inexpensive but water is not always flowing where dams are built and energy is not consistent

What are the advantages and drawbacks of geothermal power?

• There are not drawbacks of geothermal power it is a very reliable clean source.

• Clean energy but nonrenewable suitable sites are rare

• Suitable sites are abundant but the energy is not as clean as other alternative sources

• Free and easy to get to however the tools needed to get it are expensive

What are the advantages and drawbacks of tidal power?

• Renewable but limited sites are available

• There are many sites and it is renewable

• Inexpensive but it is dangerous to harness the energy

• Limited sites are available so that makes it a great alternative energy source

What are the environmental impacts of wind energy?

• Wind energy has no environmental impacts

• Wind turbines can affect local wildlife and noise levels

• Wind energy increases air pollution

• Wind energy depletes natural resources

What are the benefits of using biomass as an energy source?

• Biomass is non-renewable and expensive

• Biomass reduces waste and is renewable

• Biomass is only available in limited areas

• Biomass requires no processing before use
