Why is this class in engineering? Energy problems need engineering Physics 3070 Numbers Physics 3070: you can learn in physics what the optical spectrum is and why there is 1.34kW/m^2 incident power density from the Sun. You will also learn why solar cells work. In this class, you will learn how to best convert solar energy into electrical power (e.g. you need DC-AC converters), and also what it would take to improve the total PV system efficiency. To make meaningful decisions related to energy policy, we need numbers Example: it is not useful to say: “we have a lot of wind energy” – instead we need to say how many Joules of energy we use and how many Joules we can get out of wind at any given place. Then we can conclude what percentage of needed energy we can get from wind. 9/22/2018 Lecture 1: Introduction and Motivation

Lecture 1: Introduction and Motivation Clicker Question In 2008, total utility green power sales exceeded 5 billion kilowatt-hours (kWh), about a 20% increase over 2007. NREL Highlights Utility Green Power Leaders, National Renewable Energy Lab Press Release, April 14, 2009 Is this a lot of energy? Yes No How much electricity does your home use every month? How many home months can 5BkWh support? Note the quote goes on to say “More than 600,000 customers are participating in utility programs nationwide.” There are about 100M homes so again less than 1%. Also says Xcel is 4rth largest in terms of green energy sales. Also says most utility green energy is wind today. 9/22/2018 Lecture 1: Introduction and Motivation
