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.
This false color map shows hours of bright sunshine during the year. Solar energy may become a major source of energy in the future. Sunlight depends not only on the latitude of the location but also whether it is typically cloudy. Credit: Earth Forum, Houston Museum of Natural Science; Data from the World Resources Institute.
