The primary source of all energy on planet Earth is from the sun.Solar power is power generated directly from sunlight.This focuses on the use of nuclear power to generate electricity in Australia. This issue has been recently debated and discussed in the news and will most likely remain highly debated.

“The convectional water heater is called a two-way tank system.” (Johnston, Gibson 255) The passive solar water systems transfer heat by natural circulation using different temperatures and this enables them not to depend on pumps.
They are more commonly used in our homes due to their cheap installation.
However passive hot water systems require back up heat for cloudy days.
(Johnston, Gibson 254) “The active systems generally have higher efficiencies, their values being thirty-five to eighty percent higher than those of the passive systems.” (Ogueke 1) The two type of systems require storage tanks for their water, which is sometimes in a preheat tank for a conventional water heater.
Their variations come from the mechanisms that they use to pump water in the circulation.
A passive heater usually has a tank that plays the role of both the storage and the solar collector.Since then, solar cells have been used on small items such as calculators.They have also been an important power source for spaceships and satellites.They are becoming more popular for buildings and homes as they become more efficient.One nice thing about solar cells is that they can be placed on the roof of a building or home, not taking up any extra space. Solar cells convert the energy of photons from the sun into electricity.The above all rely on one source: solar energy which comes In the case of cold climatic conditions there might not be enough sunlight to provide a source of heat and in this case a person may consider using an electric pump for heating.“The amount of electricity required is however minimal.”(Johnston, Gibson 250) There are different types of solar water systems, passive and active solar water systems.When an electric circuit is formed across the top and the bottom of the cell, current will flow, powering electrical equipment.It takes a lot of solar cells to power a building or a home.They are usually more efficient and less costly to construct.“Active solar hot water systems employ a pump to circulate water between the collector and the storage tank.
