Flashcard: Renewable Energy Resources

Front

What is solar power?

Back

Solar power is energy harnessed from sunlight using various technologies, primarily solar panels, to generate electricity or heat.

Front

What are the main limitations of solar power availability?

Back

Solar power availability is limited by factors such as geographic location, weather conditions, and time of day, as it is dependent on sunlight.

Front

How is energy produced from biomass?

Back

Energy is produced from biomass by burning organic materials such as wood, agricultural waste, or other biological matter to release heat, which can then be converted into electricity.

Front

What are the environmental impacts of building a dam?

Back

Building a dam can lead to ecological disruption, decreased water flow, and changes in local ecosystems, which may affect fish populations and water quality.

Front

How does solar power convert sunlight into electricity?

Back

Solar power converts sunlight into electricity using photovoltaic cells that generate direct current (DC) electricity when exposed to sunlight.

Front

What are the economic advantages of solar power compared to fossil fuels?

Back

Solar power is often less expensive than fossil fuels due to decreasing technology costs, government incentives, and the absence of fuel costs.

Front

What is biomass energy?

Back

Biomass energy is renewable energy derived from organic materials, including plant and animal waste, which can be used for heating, electricity generation, or biofuels.

Front

What are the benefits of using renewable energy sources?

Back

Benefits of renewable energy sources include reduced greenhouse gas emissions, decreased reliance on fossil fuels, and sustainable energy production.

Front

What is the role of photovoltaic cells in solar energy systems?

Back

Photovoltaic cells are the key components in solar energy systems that convert sunlight directly into electricity.

Front

What are the challenges associated with solar energy storage?

Back

Challenges of solar energy storage include high costs, limited capacity, and the need for efficient technology to store energy for use during non-sunny periods.
