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.
Earth's energy balance refers to the balance between the amount of incoming solar radiation and outgoing terrestrial radiation. In a 1-year period, the overall average flow of energy to and from Earth must balance, or the global mean (average) temperature of Earth would change.
