Test: Energy - 2 - JAMB MCQ

Natural gas is a non-renewable source of energy extracted from underground reservoirs. It consists mainly of methane and is commonly used for heating and electricity generation.

Solar energy is harnessed from the sun using photovoltaic cells or solar thermal systems. It is a renewable source of energy that is converted into electricity or used for heating purposes.

Uranium is a radioactive element used as fuel in nuclear power plants. It is not classified as a fossil fuel.

Hydroelectric power is generated by the flow of water in rivers or dams. It is a renewable energy source that relies on the water cycle for its continuous supply.

Wind power is indirectly derived from the sun. The sun's heat causes temperature and pressure differences in the atmosphere, resulting in wind. Wind turbines convert the kinetic energy of the wind into electrical energy.

Non-renewable energy sources, such as fossil fuels, exist in finite quantities and take millions of years to form. Once depleted, they cannot be replenished within human timescales.

Burning fossil fuels releases sulfur dioxide and nitrogen oxides, which react with atmospheric moisture to form acids. These acids can then fall to the ground as acid rain, causing environmental damage.

The installation and setup costs associated with renewable energy sources, such as solar panels or wind turbines, can be relatively high. However, they tend to have lower operational costs in the long run.

Burning coal for electricity and heat generation is a major contributor to carbon dioxide emissions, which are a primary cause of climate change.

Renewable energy sources, like solar and wind power, have a smaller ecological footprint compared to non-renewable sources. They generally have minimal impact on ecosystems and biodiversity.
