Solar Energy What is it? energy from the sun that is converted into thermal or electrical energy This energy is in the form of solar radiation, which makes the production of solar electricity possible cleanest and most abundant renewable energy source available, and the U.S. has some of the richest solar resources in the world.  What do we use it for? generating electricity, providing light or a comfortable interior environment, and heating water for domestic, commercial, or industrial use Types of Solar Energy Passive Active Photovoltaic Solar Thermal Passive A method in which solar energy is harnessed in its direct form without using any mechanical devices. Example: Drying clothes in the sunlight Active Employs mechanical or electrical equipment for functioning and increase system efficiency Example: Water pumps are used to circulate water through the active solar energy water heating system Photovoltaic convert sunlight directly into electricity. PV gets its name from the process of converting light (photons) to electricity (voltage), which is called the PV effect Example: solar panels on a roof or solar farms (used to speed the process of direct sunlight) Solar thermal uses the sun’s energy, rather than fossil fuels, to generate low-cost, environmentally friendly thermal energy his energy is used to heat water or other fluids, and can also power solar cooling systems Benefits It reduces Utility bills Reduces carbon footprint
