Generating electricity through photovoltaic panels. The set of photovoltaic cells, grouped in photovoltaic panels, is the basic element of a photovoltaic power plant. The solar cells are responsible for capturing the sun's radiation and transforming it into electrical energy.
Wind power is the use of air flow through wind turbines to mechanically power generators for electricity. Wind power, as an alternative to burning fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation, consumes no water, and uses little land.
