Energy is the ability to cause change
Energy can be transferred from one object to another
Different forms of energy include kinetic, potential, thermal, sound, radiant, nuclear, and electrical energy
The law of conservation of energy states that energy cannot be created or destroyed, only transformed
Friction transforms mechanical energy into thermal energy
Nonrenewable energy resources are used faster than they are replaced (e.g. fossil fuels)
Renewable energy resources are replaced as quickly as they are used (e.g. wind, solar, hydroelectric)
Conserving energy (e.g. turning off lights) reduces the rate at which resources are used, and extends their availability.
Different types of energy resources have various advantages and disadvantages in terms of accessibility, cost, impact on the environment, and sustainability.
