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.
Typical electricity is generated from fossil fuel that will run out one day. Solar energy is a good alternative to replace fossil fuel as the major energy source because solar power is renewable at absolutely no cost to supply energy infinitely. 3. Environment friendly. The world pollution is getting worse. Any effort that can reduce the pollution to the environment helps to save the earth.
