II. Renewable Electric Power (Modeling)
In the United States, consumers of electric power include all sectors of society— residential, commercial, industrial, and transportation related. Because of this broad dependency, reliable and uninterruptible sources of electric power (and those with the lowest environmental impact) are important. The United States has many sources of electrical power generation—predominately coal, natural gas, nuclear power, and renewable sources. The focus of this application is renewable sources because these will not be depleted, even though some renewables can be significant polluters (such as energy from combustion of wood or municipal waste).
The following table shows data for billions of kilowatt-hours of U.S. electrical power generation for selected years from 2016 and projected to 2040.
Find an exponential function that models the billions of kilowatt-hours of renewable electric power generation, with x as the number of years after 2010. Store the unrounded model as in on your calculator, and report the rounded model as , with 3 significant digits and with base e.
