The Benefits of Solar Electricity

Solar electricity is derived from the conversion of sunlight through (PV) photovoltaic technology. Photovoltaic systems utilize the power of sunlight to power electrical equipment, such as lights, computers, and household appliances. The photovoltaics process solar energy that is free, into solar power directly. Solar energy is the most plentiful source of energy in the world, but it should be noted that solar energy is not the same as thermal technology that powers solar electricity, which is passive. This technology is commonly used for the production of hot water and space heating. The basic operation of PV cells brings together a minimum of two thin layers of semi conducting material, most often silicon. When light is exposed to these layers, electrical charges are generated, being conducted away through metallic contacts, in the form of a direct current. Single cell electrical output is small; therefore, multiple cells are encapsulated and connected together behind glass, to form panels, or modules. The...

 


Smart Grid Energy Efficiency Meters

The future of home energy efficiency involves something called the "smart meter," which will communicate the price fluctuations of energy throughout the day to the consumer, as well as consumer energy consumption habits back to the utility company. This new technology will cut out the middle man who needs to come into the home to "read the meter." The increased awareness created by a home energy saving device will hopefully encourage better conservation of energy and lead America to a more sustainable future. Currently just 6% of all households are hooked up with a smart meter, but you can get an early start by purchasing one of the inexpensive gizmos on the market.One of the meter options is EnergyHub, which "produces smart, simple, and cost-effective energy management tools that strengthen the relationship between consumers and utilities and help solve the energy problems of today and tomorrow." Time Magazine recently called this energy monitor dashboard "one of the best inventions of 2009" for its ability ...

 


Why Choose Renewable Wind Power?

Electricity produced from wind powered turbines is one of the most prevalent varieties of electricity from sustainable sources and it is the fastest-growing variety as well. Wind turbines are turned by the natural strength of the wind, so make electricity without 'burning up' any fossil fuels in the procedure. The more (harder) the wind blows, the more electricity is produced.Therefore, wind turbines are best placed where there are prolonged periods of high wind. The coast line is often a good place to site wind turbines. In fact many coastal towns and cities are supplementing their existing conventional electricity supply with electricity created from wind turbines.You can still generate energy from wind, even if the wind does not blow very hard where you live, but the return will be less. It could still be sufficient, but maybe you should check out solar panels as well. For example, it may suit your location to have a wind turbine for the winter and a couple of solar panels for the summer and winter back up...
