Chapter 18 - Concept Review - Renewable Energy

Front

What is hydrogen used for as a fuel source?

Back

Hydrogen can be burned as a fuel or used to produce electricity chemically.

Front

What is solar heating?

Back

Solar heating uses the sun’s energy to heat something directly, without moving parts.

Front

Can renewable energy sources like hydroelectric and geothermal energy produce large amounts of electricity?

Back

Disagree; while they can produce electricity, the statement is misleading as it implies they always do.

Front

What is a disadvantage of using wood as biomass fuel?

Back

Burning wood adds pollutants and can lead to deforestation, habitat loss, and soil erosion.

Front

What is an alternative to burning fossil fuels for splitting water molecules into hydrogen and oxygen?

Back

Using electricity from solar cells or wind power.

Front

Define renewable energy.

Back

Renewable energy is energy that is collected from resources that are naturally replenished, such as sunlight, wind, rain, tides, waves, and geothermal heat.

Front

What is the main advantage of using solar energy?

Back

Solar energy is abundant, sustainable, and reduces reliance on fossil fuels.

Front

What is biomass energy?

Back

Biomass energy is produced from organic materials, such as plants and animal waste, which can be used for fuel.

Front

What is geothermal energy?

Back

Geothermal energy is heat energy generated and stored in the Earth, which can be used for heating and electricity generation.

Front

What is wind energy?

Back

Wind energy is the process of converting wind into mechanical power or electricity using wind turbines.
