Renewable Energy Flashcard #2

Front

What is biomass energy?

Back

Biomass energy is energy produced from organic materials, such as plant and animal waste, which can be converted into fuel.

Front

What is photovoltaic energy?

Back

Photovoltaic energy is the conversion of sunlight directly into electricity using solar panels.

Front

What is geothermal energy?

Back

Geothermal energy is the heat that comes from the sub-surface of the earth, which can be used for heating and electricity generation.

Front

How do photovoltaic systems work?

Back

Photovoltaic systems convert sunlight directly into electrical energy without the need for a spinning turbine.

Front

What is the primary source of geothermal energy?

Back

The primary source of geothermal energy is the heat from the Earth's core.

Front

What is the difference between photothermal and photovoltaic energy?

Back

Photothermal energy uses sunlight to heat a fluid, which then produces steam to turn a turbine, while photovoltaic energy converts sunlight directly into electricity.

Front

What is the role of turbines in renewable energy generation?

Back

Turbines convert kinetic energy from moving fluids (like water or steam) into mechanical energy, which is then converted into electrical energy.

Front

What is the process of harnessing energy from geothermal plants?

Back

Energy is harnessed from geothermal plants by using hot water from underground, which is turned into steam to spin turbines.

Front

What are the advantages of using renewable energy sources?

Back

Renewable energy sources are sustainable, reduce greenhouse gas emissions, and decrease dependence on fossil fuels.

Front

What is the significance of solar energy in renewable resources?

Back

Solar energy is a key renewable resource that can be harnessed for electricity generation and heating, contributing to energy sustainability.
