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.
The bad news is that the majority of renewable energy is hydropower, which is not an exponentially improving technology. The good news is that solar energy is an exponentially improving technology, growing 30% a year in the US. If this continues, solar installations, which just hit one million in Q1 2015, will account for virtually 100% of US electricity production, according to Stanford's Tony Seba.
