Comments Off on Concrete Bases Improve Wind Turbine Tower Efficiency

Concrete is not often the greenest material choice, particularly since concrete production is one of the largest single sources of carbon emissions globally. But, for wind turbine towers, the use of concrete bases can provide a number of significant benefits, including reducing the amount of concrete needed for the footings for a tower by more than two-thirds. Concrete bases can also be more economical to install and can provide faster construction times for wind towers and also can raise tower height to increase power production

Comments Off on Are Commercial LED Replacements Ready for Prime Time?

There are increasing numbers of LED replacement products for T8 fluorescent lamps, which are widely used in retail and commercial buildings, but the US Department of Energy is warning that many of these do not yet offer comparable performance and light output versus what is supplied by using fluorescent lamps. Just because they are called replacements does not mean they are going to provide a similar level of performance. Many LED replacement lamps are highly directional, with the LEDs only emitting light in one direction

Plug-In Solar Appliance Brings Cheap Solar Power to Homes

Comments Off on Plug-In Solar Appliance Brings Cheap Solar Power to Homes

Solar power company Clarian Technologies has developed a new concept in residential solar power:  the solar appliance.  Just like a refrigerator or microwave, a homeowner can buy the Sunfish solar power system, plug it into any outdoor outlet and start feeding solar power into their home. Whereas most solar power systems require a contractor to install the module and an electrician to connect it to the electric panel through an inverter (to convert the DC power generated to AC power), Clarian says a handy homeowner can install the Sunfish themselves in about an hour. The other major bonus of such a plug-and-play-type system, is the cost.  Let’s face it, that’s the main draw.  The base model Sunfish will cost $799 with the largest running about $4,000, where a typical roof-mounted system costs a minimum of $10,000 and goes steeply up from there.
