What energy transfer occurs when using biofuels as a fuel source for cars?
Potential (burning/breaking chemical bonds) --> mechanical (moving piston in car engine)
What is one source of potential energy?
Fossil fuels, batteries, (standing) water in a dam, biofuels
What is the difference between weather and climate?
Climate relates to long-term trends and weather relates to short-term patterns
What is the difference between a biofuel and a fossil fuel such as coal?
Fossil fuels are extracted from plants/animals from over a million years ago. Biofuels are extracted from plant/animal remains from today!
What is one example of radiation?
What tool is needed to convert mechanical to electrical energy?
Generator
How is thermal energy a form of kinetic energy?
Thermal energy relies on increasing the speed of particles!
What is the Global Warming Potential (GWP)?
GWP- the ability of a greenhouse gas to trap heat.
What is the most efficient power source in the US?
Hydropower
