The Micro-grid Dream House
 
 
Today’s green technology can turn your home into a mini-power plant: Use what you can, sell the rest to the
 
grid--and take power from the grid when you need it.
 
Solar panels: A 400watt, 3-foot-by-5-foot panel made by Sunset sells on Amazon for $3000. The average
 
home would need at least 10 to meet its energy need.
 
Micro-wind turbine: The Sky-stream model from Southwest Wind-power delivers 2.4killowatts-up to 90% of
 
the average home’s use-for $12,000 to $18,000, installed.
 
Insulation: A typical home can cut 25% to 50% of energy use through simple weather proofing and from
 
energy-efficient appliance.
 
Time switch；A switch attached to a timer directs the power from the solar panels to batteries or onto the
 
grid. During the peak hours of noon to 2 p.m.. When power is most expensive, the house runs off the
 
batteries.
 
Batteries: Though not essential for a grid-connected system, battery storage allows more flexibility to go on
 
or off grid.
 
Smart meter: A commercial time-of-day electric meter shows the varying price of electricity, so the owner
 
can use less and sell more during peak hours.
 
Electric car: By next year, this power system could include a plug-in hybrid vehicle. The car battery can
 
serve as additional backup storage for the home and the grid.
