Interactive Map: Four Ways to Look at Carbon Footprints. About this graphic Graphics by Stephen Rountree and Adam Marr Source: World Resources Institute CAIT 2.0 climate data explorer Emissions data and national boundaries are from 2010.
For current emissions, per capita emissions, and intensity, the data are measured in tons of "carbon dioxide equivalent. " That is, they include carbon dioxide and five other greenhouse gases (methane, nitrous oxides, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride) as measured by their global warming potential. Cumulative emissions are measured in tons of carbon dioxide only. The emissions of Brazil and Indonesia may be understated because the numbers do not include calculations on land use change and forestry. There are high uncertainties in current measures of deforestation's contribution to greenhouse gas emissions, as international authorities work to develop a consistent methodology. Energy.

IntroE.pdf. What is Energy? Energy is the capacity of a system to do work.
That system may be a jet, carrying hundreds of passengers across the ocean. A baby’s body, growing bone cells. A kite, rising on the wind. Or a wave of light crossing a space. In moving or growing, each of these systems is doing work, and using energy. Some of the many forms that energy takes are: Mechanical energy, which includes - Potential energy, stored in a system. - Kinetic energy, from the movement of matter. Radiant or solar energy, which comes from the light and warmth of the sun. Humans converted energy from one form to another when they lit the first fire.
Sound is a form of kinetic energy. Many times, multiple conversions are involved. To measure energy, we use the "heating value" of the fuel, which indicates how much of a certain fuel is converted to how much heat. The Energy Story - Chapter 5: Stored Energy and Batteries. Energy cannot be created or destroyed, but it can be saved in various forms.
One way to store it is in the form of chemical energy in a battery. When connected in a circuit, a battery can produce electricity. If you look at a battery, it will have two ends &emdash; a positive terminal and a negative terminal. If you connect the two terminals with wire, a circuit is formed. Electrons will flow through the wire and a current of electricity is produced. Inside the battery, a reaction between the chemicals takes place. How the Chemical Reaction Takes Place in a Battery A very simple modern battery is the zinc-carbon battery, called the carbon battery for short.
This battery contains acidic material within and a rod of zinc down the center. When zinc is inserted into an acid, the acid begins to eat away at the zinc, releasing hydrogen gas and heat energy. If a rod of carbon is inserted into the acid, the acid does nothing to it. Sidebar Volta called his battery the Voltaic Pile.
