Energy Efficiency and Generation

To gain an appreciation for the impact that improved efficiency can have, it is useful to examine the price we pay for inefficiency, and nowhere is this more apparent than in the generation of electric power.  

Typically, the process converts the latent energy in a fuel stock (coal, gas, uranium) into mechanical energy in a generator and ultimately electrical energy.
In a traditional coal plant, only about 30-35% of the energy in the coal ends up as electricity on the other end of the generator. The most efficient gas-fired generators achieve a similar level of efficiency.

However, other generation sources like wind and hydro power use the mechanical energy of moving masses of air or water to produce electric energy. Still other devices, such as fuel cells, use chemical reactions to generate electric energy.

This interest group will focus on education and advocacy around energy efficiency and alternative methods of energy generation.
