TED-Ed: The tech that seems to break the laws of physics | Anna Rothschild

Heat pumps are an efficient and climate-friendly alternative to traditional heating systems. They use electricity to transfer heat from the air or ground, achieving efficiencies of up to 500%. While they reduce CO2 emissions, challenges include the environmental impact of refrigerants and high installation costs. Innovations and subsidies are helping to overcome these barriers, making heat pumps a viable solution for reducing global energy-related emissions.

What is the principle behind the efficiency of heat pumps compared to traditional heating systems?

Explain how heat pumps can provide more heat output than the energy input.

What are the environmental concerns associated with the use of refrigerants in heat pumps?

Describe the process by which air conditioners and heat pumps transfer heat.

What challenges do heat pumps face in colder climates?
