Back in July 2016, we hosted an educational event that featured 2 local solar installers plus Tesla Motors. The neighborhood got a chance to learn about how a few simple changes in their household can reduce energy, how solar energy works, and how electric vehicles are becoming more mainstream. Over 100 people attended the event. Many had a chance to ride in a Model S and Model X.

Kilowatt Hour (kWh)
Energy = Power x Time
1 kilowatt hour =
the energy delivered by 1000 watts of power
over a one hour time period

What is a SREC?
A SREC is a Solar Renewable Energy Credit.
It equals a Mega watt of clean power created.
You can lock in a 5 year contract.
Example: $125/mega-watt hour
1.00 mega-watt hours x $125 = $125
$125 * 5 = $625/year

•Payback number is conservative. SREC amount could be substantially higher. Also, potential
electricity savings is considered lower due to tree branches that will be removed.
•Assumption: $.10/kWh and no increase in electricity charges
$5,000/10yr -$5

Paul will talk about fossil fuels and the hazard to the environment

Paul will talk about the importance of renewable energy and that it is not too late.
It will also save you money.
A 1986-era 18 c.f. fridge uses 1400 kWh a year, while a modern energy-efficient model uses only 350 kWh — a whopping 75% reduction. At 15¢ kWh, trading in a pre-1986 fridge for a new efficient one would save about $158 a year in electricity costs.
Switching from your 10-year-old top loading washer to a new front loading efficient model can save you almost $200 a year.
Every second, the Sun produces 400 trillion watts, which is the same amount of energy as about a trillion 1 megaton bombs!
In one minute of solar energy, the whole planet’s energy consumption can be complete.
