Renewable Energy

What is an example of renewable energy?

• coal

• wind energy

• fussil fuels

• nuclear energy

Answer explanation

Wind energy is a renewable energy source generated from the wind, making it sustainable and environmentally friendly. In contrast, coal and fossil fuels are non-renewable, and nuclear energy, while low in emissions, is not classified as renewable.

(a)   refers to energy sources that can be replenished naturally, such as solar and wind energy.

Answer explanation

Renewable energy refers to energy sources that can be replenished naturally, such as solar and wind energy. This term encompasses various sustainable energy options that are essential for reducing environmental impact.

Burning fossil fuels releases greenhouse gases, which contribute to (a)   .

Answer explanation

Burning fossil fuels releases greenhouse gases, which trap heat in the atmosphere, leading to climate change. This process disrupts weather patterns and increases global temperatures.

(a)   refers to harmful chemicals or materials that damage the air, water, or soil.

Answer explanation

Pollution refers to harmful chemicals or materials that damage the air, water, or soil. It encompasses various forms of contamination that negatively impact the environment and public health.

Energy that comes from natural sources that don’t run out.

• Fossil fuels

• Pollution

• Renewable energy

• Climate change

Answer explanation

Renewable energy refers to energy sources like solar, wind, and hydro that are naturally replenished and won't run out, unlike fossil fuels. This makes it the correct choice for energy that comes from sustainable natural sources.

Long-term changes in global temperature and weather patterns.

• Fossil fuels

• Pollution

• Renewable energy

• Climate change

Answer explanation

Climate change refers to long-term shifts in temperature and weather patterns, primarily driven by human activities like burning fossil fuels and deforestation, leading to global warming and altered climate systems.

Harmful substances released into the environment.

• Fossil fuels

• Pollution

• Renewable energy

• Climate change

Answer explanation

Pollution refers to harmful substances released into the environment, affecting air, water, and soil quality. Unlike fossil fuels, renewable energy, and climate change, pollution specifically denotes the release of these harmful substances.

Non-renewable energy sources like coal and oil.

• Fossil fuels

• Pollution

• Renewable energy

• Climate change

Answer explanation

Non-renewable energy sources like coal and oil are classified as fossil fuels. They are derived from ancient organic matter and are a major source of energy, but they contribute to pollution and climate change.
