Energy
Energy is the main idea around this whole stove project. Because of this, understanding what energy is and the science behind all of the stoves. Energy is the ability to do work. Take this quiz to see how much you know:

Energy Information
This is the US energy consumption by source.
Energy is the ability to do work, measured in joules. Joules are equivalent to one newton-meter. Potential energy is stored energy. There are five types: elastic, chemical, nuclear, electrical, and gravitational energy. Kinetic energy is energy that is moving. There are also five types of kinetic energy: heat, electromagnetic, mechanical, mechanical wave, and electrical energy.
There are two types of energy resources: renewable and non renewable resources. Renewable resources are completely sustainable resources that can be used indefinitely. Biomass, solar, and wind are examples. Non renewable energy is energy that exists infinite amounts. Oil, coal, and natural gas are examples.
Energy transformation is energy converted from one form to another. Energy efficiency is using less energy to do the same thing.
Combustion is the rapid combination of a substance with oxygen producing heat and light, or the process of burning something. Incomplete combustion results when not enough oxygen is there to burn all the fuel. As a result, carbon monoxide is produced.
The carbon cycle is a cycle that carbon goes through. This includes photosynthesis, cellular respiration, and other processes that make up the flow in which carbon travels. Fire is the rapid combination of carbon and oxygen. This produces heat and light. Heat is the transfer of thermal energy from one object to another because of temperature differences. Heat flow is when heat is transferred by atoms colliding with each other. Thermal energy is the total potential and kinetic energies having to do with the particles in an object and how it moves. This depends on the mass, phase (solid, liquid, gas), and temperature of the object.
Conduction, radiation, and convection are the three ways heat moves. Conduction is when heat transfers between two objects. Radiation is the transfer of energy through the air. Convection is the transfer of thermal energy through a gas or fluid.
Burning fossil fuels produces CO2. This traps heat in the atmosphere and it is the main contributor to climate change. Carbon monoxide is a gas that keeps the hemoglobin in your blood from getting oxygen. CO is produced by the incomplete combustion of fuel. CO2 and other emissions from a fire cause countless diseases: bronchitis, pneumonia, COPD, and many others. These are usually caused by PM or particulate matter getting into your lungs.
