Conservation of Energy
... Heat and work are the methods of transferring energy for a system in thermal equilibrium Q represents the net heat transfer—it is the sum of all heat transfers into and out of the system. Q is positive for net heat transfer into the system. W is the total work done on and by the system. W is positiv ...

Energy Flow Introduction
... Every cell in the monkey's body (and ours) is constantly converting the stored solar energy in glucose into work and heat. The work is used to carry on cell processes like growing, reproducing, moving molecules around, and getting rid of waste. The heat is a byproduct of the fuel "burning" process. ...

Alternative energy
Alternative energy is any energy source that is an alternative to fossil fuel. These alternatives are intended to address concerns about such fossil fuels.The nature of what constitutes an alternative energy source has changed considerably over time, as have controversies regarding energy use. Today, because of the variety of energy choices and differing goals of their advocates, defining some energy types as ""alternative"" is highly controversial.In a general sense, alternative energy as it is currently conceived, is that which is produced or recovered without the undesirable consequences inherent in fossil fuel use, particularly high carbon dioxide emissions (greenhouse gas), an important factor in global warming.
