In general, the concept of energy refers to "the potential for causing changes". The word is used in several different contexts. The scientific use has a precise, well-defined meaning, whilst the many non-scientific uses often do not. (see here.)

In physics, energy is the ability to do work and has many different forms (potential, kinetic, electromagnetic, etc.) No matter what its form, physical energy has the same units as work; a force applied through a distance. The SI unit of energy, the joule, equals one newton applied through one meter, for example.

Washington, Stop Dithering, US Goals on Climate Urgently Needed
dotdotdotdotdotdotdotdotdotdotdot Thu, 05 Nov 2009 05:47:00 -0500
As the last round of "intersessional" climate talks before Copenhagen opened today in Barcelona, all eyes were looking in the same direction they were when we left Bangkok three weeks earlier: at the United States. Without American numbers on mitigation (or emissions reductions) and finance (for developing nations to build their own clean energy economies, and also to adapt to the impacts of climate change), any real forward progress in the talks is just about impossible.
Ethiopian Rift Shows How Continents Can Split, Create New Ocean
dotdotdotdotdotdotdotdotdotdotdotdotdotdotdotdotdotdotdot Wed, 04 Nov 2009 08:10:00 -0500
A new study reported by the Addis Ababa University in Ethiopia and the University of Rochester sheds light on how the continents move, and oceans are created. In 2005, a gigantic, 35-mile-long rift broke open the desert ground in Ethiopia. At the time, some geologists believed the rift was the beginning of a new ocean as two parts of the African continent pulled apart, but the claim was controversial. Now, scientists from several countries have confirmed that the volcanic processes at work beneath the Ethiopian rift are nearly identical to those at the bottom of the world's oceans, and the rift is indeed likely the beginning of a new sea.

President Lyndon Johnson and British Prime Minister Margaret Thatcher made stark warnings about global warming decades ago, but convincing evidence for action only amassed in recent years, experts say. A 190-nation U.N. conference in Copenhagen in December is due to agree a new U.N. pact to curb greenhouse gas emissions to slow a rise in temperatures to prevent floods, droughts, wildfires or rising sea levels.
