The sun is a powerful source of energy that has produced energy for billions of years. This form of renewable energy uses photons or rays of solar energy and heat from the sun to absorb energy, which in turn generates electricity. Along with solar thermal19 technologies, it is believed that solar energy is an adequate source to supply our19 energy needs that can be used for heating purposes and electricity. This can offset the energy used and often wasted, particularly with heating, cooling, ventilation, and additional power sources.

Thermal energy from the sun is defined as low, medium, or high energy that is collected through thermal energy technology. The two basic types of solar heating systems are liquid or air. These systems are heated in a device where a fluid is heated by the sun called a collector. These systems that use liquid heat through a hydronic collector. An air-based system heats energy from in the sun in an air collector.

Solar energy can also be converted into electricity through photovoltaic (PV devices) or solar cells. This converts light from the sun into electricity. It uses concentrating19 solar19 power and various technologies to utilizing solar energy. This allows a direct conversion of electricity, without a large and bulky mechanical generator. The devices to convert photovoltaic energy generally have a quick installation and can be installed in a variety of sizes. They are also correlated with minimal impact on the environment, so the water system and no by-products are emitted.

Solar technology is characterized as either passive solar or active depending on the way sunlight is captured, converted, and distributed. Active solar technology uses electrical or mechanical equipment where it converts sunlight through photovoltaic panels or solar thermal collectors. Passive solar technology uses materials such as thermal mass or light from the sun. These properties naturally circulate the air and heat from the sun and Increase its energy flow19. Passive solar technology is more prevalent while passive solar technologies are believed to be more environmentally friendly and alternate resource as they reduce the demand and need for non-renewable energy sources.

Opponents of solar energy say that utilizing the sun has its downfalls since the amount of sun that reaches the earth is not consistent and can affect the amount of energy that an area receives and is dependent upon. One solution is to create the necessary technologies needed for consistent and steady solar energy.
