### Renewable Generators Double/Total 14,723 in PJM Power Pool

Explosive growth in the number of renewable energy generators continues with 14,723 renewable generators connected to the grid in the PJM power pool, the world's largest wholesale power market.  See http://www.pjm-eis.com/.  Many of the renewable generators connected to the grid and feeding power into it are residential solar systems, while others are large, utility-scale wind, hydro, landfill gas, and biomass.

How quickly is the number of renewable energy generators increasing?  Doubling in about 1 year.
At the end of 2009, PJM had 6,700 renewable generators in its system.

As distributed generation proliferates the electric industry is seeing now its future.

1. Hi John,

What if those geothermal electric generators where running achohol or even liquified atmosphere through them instead of water (something with a much lower vaporization point)??? Just a thought.

2. Geothermal heat pumps don't generate electricity and are not counted in the 14,700 renewable energy generators. Geothermal heat pumps use the temperature of the ground to use less energy or electricity that is supplied to the home. They heat and cool space efficiently but don't generate their own power.

All the 14,700 renewable energy generators use some fuel to make electricity and are connected to the pjm grid to supply electricity.
