Energy forms and uses

Lecture 3 materials are covered in Chapters 2 and 3 of Energy Systems & Sustainability, 2/e (2012). This lecture covers a lot of ground, starting with the definition of primary energy, the units used to quantitate energy and the consequences of the first law or thermodynamics. Global primary energy resources and consumption are introduced with an overview. 

In the second section we focus on how our current energy systems work, or don't, and how our use of energy has changed and continues to expand. We look at primary energy production and consumption in three fossil fuel-dependent, industrialized countries - the UK, Denmark and the US - are compared with one another. We contrast that with the profiles of three very different countries: France, dependent on nuclear power; India, reliant on coal and biomass; and China, addicted to coal. It's worth noting that most of the data presented in our text is from 2008 and 2009 and national energy profiles have begun to change.
​I've added more current information about energy use in the US, Vermont and on our Randolph Center campus.
