APES unit 6 Energy Review

Front

What is geothermal energy?

Back

Geothermal energy is heat energy generated and stored in the Earth. It can be used for electricity generation and direct heating applications.

Front

List the renewable resources derived from the sun.

Back

Biomass, wind, solar energy, and hydroelectric power are renewable resources derived from the sun.

Front

What is passive solar design?

Back

Passive solar design refers to the use of building materials and design features to naturally collect, store, and distribute solar energy for heating and cooling.

Front

What is the sequence of electricity generation using wind energy?

Back

1. Wind turns the wind turbine blade. 2. The gearbox transfers mechanical energy to the generator. 3. The generator converts mechanical energy into electrical energy. 4. Electricity is transferred to the grid.

Front

Which fuel contains the most sulfur?

Back

Coal contains the most sulfur compared to wood, oil, and natural gas.

Front

What is biomass energy?

Back

Biomass energy is derived from organic materials, such as plants and animal waste, and can be used for heating, electricity generation, and as biofuels.

Front

What is the environmental impact of biomass energy?

Back

Biomass energy can lead to deforestation if not managed sustainably, as trees are often cut down to produce biomass fuel.

Front

What is the role of a generator in wind energy production?

Back

A generator converts mechanical energy from the wind turbine into electrical energy.

Front

What is the purpose of a gearbox in wind turbines?

Back

The gearbox increases the rotational speed of the turbine blades to match the generator's required speed for electricity generation.

Front

What are the benefits of passive solar design?

Back

Benefits include reduced energy costs, improved comfort, and decreased reliance on non-renewable energy sources.
