Energy use in cooking is an important topic in physics. It deals with how energy moves and how well we use it. Different cooking methods use different amounts of energy, which affects our homes and the environment.

1. Types of Cooking Appliances:

• Electric Ovens: These usually use about 2-5 kWh each time you cook.
• Gas Stoves: These use around 0.1-0.5 therms each hour. (1 therm equals 29.3 kWh).
• Microwaves: These typically use about 0.6 kWh per hour.

2. Energy Efficiency:

• Induction Cooktops: These are very efficient, using about 90% of the energy.
• Traditional Electric Stoves: These use around 70% of the energy.
• Slow Cookers: These use about 0.7-1.5 kWh.
• Pressure Cookers: These can save time and energy by cutting cooking time down by up to 70%.

3. Household Impact:

• In Sweden, cooking makes up about 10-15% of the total energy used at home.
• Using energy-efficient appliances can help families save up to 30% on their energy bills.

By understanding how cooking affects energy use, we can make smart choices. Choosing energy-efficient appliances not only saves energy but also helps protect the environment by reducing our carbon footprints.
