Photovoltaic, PV, Solar, its all great!

Welcome to Ask Doug The Electrician!

I was reading about photovoltaic systems today and found some interesting facts and information that you should be aware of.

Some Advantages of a Photovoltaic/Solar system:

No moving parts, minimal maintenance
Safe and simple operation
High dependability, durable and long life (30+ years)
Scalable in output, from micro-watts to millions of watts (megawatts)
Silent operation
Maximum output coincident with peak utility power loads (summer time)
No emissions, no pollution
Portable, easy and fast to install anywhere
Available everywhere there is sunlight.
Ability to integrate attractively into existing and new buildings

The U.S. electricity demand was almost 4 trillion at watts (4 Terawatts or TW) and is growing at approximately 1.7% per year. Current projections place demand somewhere between 11 TW and 18 TW by 2050.
Thanks again for checking out Ask Doug The Electrician!

[url=]Earth 4 Energy[/url], Considering the rate at which our planet is getting exploited of its non renewable energy sources and the dramatic climatic changes happening due to the consumption of these minerals, we have to shift focus and keep our options open. Renewable energy is a form of energy that can never extinguish. Where as coming to wind energy, a wind mill can be constructed in a backyard and can be utilized as an electricity generator. Wind mills should be taken as an option only in places where there are moderately strong winds. Places in high altitudes, where there is enough amount of wind to move the blades. Renewable energy is a source of energy that can never get exhausted or the energy source that we can never run out off. Tidal energy is now being studied and harvested. So these are some of the renewable energy sources that we are using.
