Solar power

Definition

Solar power is the energy harnessed from the sun's radiation, primarily through technologies like solar panels that convert sunlight into electricity or heat. This renewable energy source plays a critical role in advancing green economy initiatives and promoting sustainable development by reducing reliance on fossil fuels, lowering greenhouse gas emissions, and supporting energy independence.

5 Must Know Facts For Your Next Test

1. Solar power accounts for a rapidly growing share of global energy production, with significant advancements in technology making it more efficient and cost-effective.
2. The use of solar power can lead to reduced electricity bills for consumers by allowing them to generate their own energy and potentially sell excess power back to the grid.
3. Solar farms, which are large-scale installations of solar panels, contribute significantly to national energy grids and can power thousands of homes.
4. The integration of solar power into building designs, known as building-integrated photovoltaics (BIPV), promotes energy efficiency and sustainability in urban environments.
5. Government policies and incentives play a crucial role in promoting solar energy adoption, including tax credits, rebates, and feed-in tariffs to encourage investment in solar technology.
