The Law of Conservation of Energy tells us that energy can't be made or destroyed. It can only change from one form to another. This idea affects our daily lives in many ways:
Energy at Home:
In a typical American home, about 10% of the energy goes to heating, while 30% is used for cooling. Knowing how energy changes forms can help us waste less.
Getting Around:
Cars change the chemical energy in fuel into movement energy, but they only use about 20% of that energy effectively. This means we need to improve electric and hybrid cars.
Green Energy:
Wind turbines turn wind energy into electrical energy. In 2020, wind energy made up about 8.4% of all electricity in the U.S. This shows we're moving towards more sustainable energy sources.
These examples show us that the Law of Conservation of Energy is important. It helps us think about how to use energy better every day.
