LED Light Bulbs (light-emitting diodes) have come a long way, now able to replace 75-100 watt incandescent bulbs with equivalent light output and only consuming 3-13 watts, the choice to switch to LED home light bulbs has never been easier.
The most notable advantages of LED light bulbs over conventional light bulbs are Led light bulbs last upwards of 50,000 hours, so if you buy a LED light bulb today and leave it on for 8 hours a day you will not have to change for over 10 years.
They Cost more than a Normal Globe but they last longer and are better for the Environment..
You could replace an old 60Watt Globe with a 7Watt LED Globe.. which means less power consumed.
For example, a 7 watt LED home light bulb (60 watt direct replacement) will cost $2.00 a year to run left on for 8 hours a day vs. an incandescent which will cost $20.00 and you will have to change it 2-3 times every year.
LED lights are available in all your favorite fixtures from bulbs to tube, and from dimmable to spot lights.

A fresh-water wind farm is taking shape at Lake Erie and when completed will provide 20 megawatts and get on to about one gigawatt power by 2020. Huge individual turbines 300 feet tall, to be built by GE will be erected off Ohio, Cleveland. Better designs: These are special gearless super-efficient turbines, with three 176-foot long blades, which run with the help of a giant ring of magnets. The blades are longer due to strategically placed carbon fibre, and lighter too. Many moving parts like gearbox, coils and starter brushes are eliminated with resultant reduced maintenance. The giant magnetic ring array helps the turbine generate power even at very low speed. Rejuvenating wind energy industry: As land-based turbines are facing a lack of interest and demand, wind energy industry is facing a setback. This new-design turbines to tap ...
