Thermal Energy and Home Heating
• Home heating as a model system for the
greenhouse effect. Many similarities.
• Practical application in energy consumption:
– How much energy and money can we save for

our homes?
– What does this correspond to in greenhouse
gas emissions?
• To answer this and other questions we will look
at:
1
Topics
• Power and Thermal Energy.
• Where our energy comes from: Chemical energy
and energy resources.
• Energy in humans.
• Energy in homes and home heating at constant
temperature.
• What’s the difference between heat, thermal
energy and temperature?
• How is heat transferred to the environment or
other objects? Conduction, convection and
radiation.
• Isolating homes: Thermal properties of materials.
