Energy Crisis

The following resource of a renewable energy is ....

• Coal

• Wind

• Natural Gas

• Petroleum

The following resource of a non-renewable energy is ....

• Solar

• Hydropower

• Natural Gas

• Wind

The disadvantage of using petroleum as a source of energy is ....

• it produces clean and fresh air

• it can be used repeatedly without limit

• it creates pollution when burned

• it is easy to replace with wind energy

The disadvantage of using solar energy in daily life is ....

• it is very expensive to produce smoke

• it cannot be used at all during the night

• it causes air pollution

• it will run out in a few years

In City X, the number of private vehicles has increased rapidly in the past 5 years. People rarely use public transportation. Most households use air conditioning all day, even when the weather is mild. The demand for electricity is rising, and power shortages have become more frequent.

The main cause of the energy crisis in City X is ....

• people use too many bicycles.

• the weather is always cold.

• overuse of private transportation and home appliances.

• everyone is switching to renewable energy.

A village in Region Y has been using diesel generators for electricity for many years. Recently, the cost of diesel has gone up, and the supply is often delayed. The villagers still rely only on diesel and haven’t explored renewable sources. Now, blackouts occur more often.

The main factor causing the energy crisis in the village is ....

• lack of fuel supply and dependence on a non-renewable source.

• too many solar panels were installed.

• the village uses too much wind power.

• people walk too much instead of using machines

“The demand for non-renewable energy sources such as coal and oil is increasing rapidly. However, the supply of these resources is limited and cannot keep up with the demand.”

The most likely impact of this situation is shown on ....

• energy supply will be sufficient forever

• energy prices may increase and shortages may occur

• renewable energy sources will be exhausted

• pollution levels will decrease

In a small village, the residents decided to reduce their dependence on fossil fuels. They installed solar panels on rooftops and used wind turbines to power water pumps for irrigation. Now, they no longer rely on gasoline generators and have seen a drop in air pollution.

The following action best supports the villagers’ efforts to save energy and protect the environment is ....

• replacing wind turbines with diesel engines

• using coal-powered electricity instead of solar panels

• expanding the use of solar and wind energy in nearby areas

• returning to using gasoline generators at night

Solar energy is a renewable resource that comes from the Sun. It is clean and available in many parts of the world. The activities below that show the use of solar energy in daily life are ....

• Boiling water using firewood

• Charging a phone using a solar power bank

• Turning on a lamp powered by solar panels

• Driving a car using gasoline

Petroleum is a non-renewable resource that is processed into fuel and other useful products.

The following activities that show how petroleum is used in everyday life are ....

• cooking with gas on a stove

• using solar-powered garden lights

• driving a motorcycle that uses gasoline

• turning on a wind-powered fan
