All Flashcards
What is the effect of using solar energy on air pollution?
Reduces air pollution by decreasing the need for fossil fuel combustion.
What is the effect of high upfront costs on solar energy adoption?
High costs can limit the adoption of solar energy, especially in low-income communities.
What is the effect of manufacturing solar panels on fossil fuel consumption?
The production of PV cells requires fossil fuels, contributing to carbon emissions.
What is the effect of weather conditions on solar energy production?
Limited efficiency by sunlight so energy can not be collected under specific weather conditions such as night
Why is solar energy considered a sustainable energy source?
The sun is a virtually inexhaustible source of energy.
Explain the role of electrons in generating electricity from solar panels.
Sunlight excites electrons in PV cells, causing them to flow and create an electrical current.
How does solar energy contribute to reducing carbon emissions?
It doesn't produce greenhouse gases during operation, reducing reliance on fossil fuels.
What is the primary material used in manufacturing photovoltaic cells?
Purified silicon.
Explain why solar panels are wired to an electrical grid.
To distribute the electricity generated to homes, businesses, and other users.
What is the difference between solar energy and solar thermal energy?
Solar panels directly convert sunlight to electricity, while solar thermal systems use sunlight to heat water or air.
How does using solar energy promote sustainability?
Reduces reliance on finite fossil fuels, lowers carbon emissions, and promotes energy independence.
How can government incentives promote solar energy?
Tax credits, subsidies, and rebates can lower the initial cost of solar panel installation.
