The frontal lobe is the part of the brain that controls important cognitive skills in humans, such as emotional expression, problem solving, memory, language, judgment, and sexual behavior. It is, in essence, the âcontrol panelâ of our personality and our ability to communicate.
In order for the power grid to function, demand for energy must exactly match supply. Power demand is relatively predictable and conventional power plans, like nuclear plants and natural gas, can adjust output accordingly. Solar and wind power, however, cannot easily adjust output. They also provide power unpredictably relative to conventional power sources.
1. Solar energy is free although there is a cost in the building of collectors and other equipment required to convert solar energy into electricity or hot water. 2. Solar energy does not cause pollution. However, solar collectors and other associated equipment / machines are manufactured in factories that in turn cause some pollution. 3. Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid. 4. Many everyday items such as calculators and other low power consuming devices can be powered by solar energy effectively. 5.
