Strategies to Increase Energy Supply

What are the two main strategies for increasing energy supply?

• Only using non-renewable fossil fuels

• Using non-renewable fossil fuels and nuclear power, and developing renewable energy sources

• Only using renewable energy sources

• Reducing energy consumption

Which of the following is a non-renewable energy resource?

• Solar power

• Hydro-electric power

• Wind power

• Nuclear power

What is a disadvantage of using biomass as an energy source?

• It cannot be used in low-tech applications

• It contributes to carbon emissions

• It is not available in different environments

• It is very expensive to produce

What is an advantage of wind energy?

• It is cheap to construct and maintain

• It does not face any objections

• It is always available

• It creates jobs in the local area

Which of the following is a disadvantage of hydro-electric power (HEP)?

• It is not efficient

• It is not suited to remote, upland environments

• It can lead to the displacement of people

• It cannot control flooding downstream

What is a disadvantage of tidal energy?

• It has no impact on marine ecosystems

• It is very cheap

• It is very expensive

• It is not effective in areas with a high tidal range

Which renewable energy source is very effective in areas of volcanic activity?

• Wave energy

• Wind power

• Geothermal energy

• Solar power

What is a disadvantage of wave energy?

• It is consistent

• It cannot provide energy to isolated coastal settlements

• It is very cheap

• It is very expensive to construct

Which renewable energy source is very effective in areas with high sunshine totals?

• Solar power

• Hydro-electric power

• Biomass

• Wind power

What is a disadvantage of solar energy?

• It depends on the amount of sunlight

• It is very cheap

• It cannot be used in areas with high sunshine totals

• It is not effective in converting sunlight to electricity
