Renewable EnergyRenewable Energy

Beyond the raw cost of fuel there are the Hidden Costs from our dependence on Fossil Fuels.

The global warming issue is no longer under debate & with the rising cost of fossil fuels, Renewable Energy must become an option!

• Macro Economic Costs

• National Security

• Air Pollution

• Health Related Costs

• Water and Land Pollution

• Thermal Pollution

Some of these costs are:


Air Quality

SMOG 12.5 tons NOx

Acid Rain 20 tons SOx

Global 3,000 tons CO2

Warming

Resource Conservation

Oil 5,500 barrels, or

Coal 1,600 tons, or

Natural 350 million

Gas cubic feet

30-year Lifetime Emission Savings

Basic Principal of Solar PowerBasic Principal of Solar Power



How Solar Cells WorkHow Solar Cells WorkPhotons from the sun shine on the solar cell. The photons actually penetrate into the silicon and randomly strike silicon atoms. When a photon strikes a silicon atom, it ionizes the atom, giving all its energy to an outer electron and allowing the outer electron to break free of the atom.

The photon disappears from the universe and all its energy is now in the form of direct electron movement.



The DC current is taken from the solar cells and The DC current is taken from the solar cells and manipulated into an AC waveform through an manipulated into an AC waveform through an inverter. inverter.

Inverters sense the voltage and frequency of the AC Inverters sense the voltage and frequency of the AC systems that they are attached to and begin to systems that they are attached to and begin to “push” current against that system.“push” current against that system.

Inverters come in many shapes and sizes for all types of environments.
