Before You Watch Our Lecture Maximize your learning experience by reviewing these carefully curated videos and readings we assign to our students. Our Lecture Watch the Stanford course lecture. An energy system converts primary energy resources like fossil fuels or wind into energy services. Energy services are what humans care about, like hot showers and cold beverages. There are energy losses each time we convert energy from one form to another. Energy systems are most efficient when we can closely match the resource with the service (e.g., using sunlight for illumination). The earth is an open energy system that is always getting new energy from the sun. Energy cannot be created or destroyed, but we can theoretically run out of certain forms of energy like fossil fuels. Fossil fuels are a stock resource (we have a set amount on earth) that can meet the world’s energy needs many times over. However, we need to stop using fossil fuels due to their significant environmental and climate
