Students explore energy efficiency, focusing on renewable energy, by designing and building flat-plate solar water heaters. They apply their understanding of the three forms of heat transfer (conduction, convection and radiation), as well as how they relate to energy efficiency. They calculate the efficiency of the solar water heaters during initial and final tests and compare the efficiencies to those of models currently sold on the market (requiring some additional investigation by students). After comparing efficiencies, students explain how they would further improve their devices. Students learn about the trade-offs between efficiency and cost by calculating the total cost of their devices and evaluating cost per percent efficiency and per degree change of the water.

Weatherization offers energy and non-energy benefits to households. It involves insulating homes, installing energy-efficient systems, and reducing energy bills. Non-energy benefits include improved health outcomes, such as reduced thermal stress and asthma symptoms. However, challenges like deferred assistance, low coverage, and bias against renters limit the program's impact.

The world energy system is experiencing seismic shifts, with a rapid expansion of low-carbon fuels and energy efficiency. However, fossil fuels still dominate investments despite the need to reduce greenhouse gas emissions. Different countries prioritize energy RD&D in diverse ways, and state-owned enterprises play a significant role.
