SOC 1040- energy midterm 1

Energy principle 1

Energy is a physical quantity that follows precise natural laws. (energy can be tranferred from systems, energy cant be created nor destroyed, there are different types of energy)

Energy principle 2

physical processes on earth are the result of energy flow through the earth (earths weather and climate are driven by energy from the sun)

Energy principle 3

biological processes depend on energy flow through the earth system. (Sun is the primary source of energy)

energy principle 4

various sources of energy can be used to power human activities (Human use of energy has evolved overtime, sources either renewable/nonrenewable)

energy principle 5

energy decisions are influenced by economic, political, environmental, and social factors. (energy systems evaluated using costs v benefits)

energy principle 6

amount of energy used by human society depends on different factors (human population growth & economic development drive global energy demand, energy conservation reduces overall resource consumption)

energy principle 7

quality of life of individuals and society is affected by energy choices (access to affordable energy resources affects human health, low-income populations vulnerable to negative environmental & health impacts of energy choices)
