Unit 23

Front

What is a nonrenewable energy resource?

Back

A nonrenewable energy resource is a natural resource that cannot be replenished in a short period of time. Examples include fossil fuels like coal, oil, and natural gas.

Front

What is organic chemistry?

Back

Organic chemistry is the branch of chemistry that deals with the structure, properties, composition, reactions, and synthesis of carbon-containing compounds.

Front

What is conservation in the context of energy use?

Back

Conservation refers to the practice of using less energy by reducing consumption and increasing efficiency, such as carpooling to reduce the number of vehicles on the road.

Front

Which energy source has the least impact on global climate change?

Back

Producing energy using hydroelectric plants has the least impact on global climate change compared to fossil fuels.

Front

What is a limitation of wind energy?

Back

Wind turbines are only effective in certain areas where wind speeds are adequate, limiting their use in regions with low wind.

Front

Define renewable energy resources.

Back

Renewable energy resources are natural resources that can be replenished naturally over short periods of time, such as solar, wind, and hydro energy.

Front

What is the primary environmental concern with coal energy production?

Back

The primary environmental concern with coal energy production is the high level of carbon emissions and pollutants released into the atmosphere.

Front

Explain the concept of energy efficiency.

Back

Energy efficiency refers to using less energy to provide the same service or achieve the same outcome, thereby reducing energy waste.

Front

What is the role of biomass in energy production?

Back

Biomass is organic material that can be used as a renewable energy source, such as plant and animal waste, which can be converted into biofuels.

Front

What are the advantages of using solar energy?

Back

Advantages of solar energy include its abundance, renewability, and the fact that it produces no direct emissions during operation.
