Solar heating systems range between $3,000 and $4,000 and can provide a
payback period as short as one and a half years.
New wireless sensors developed at Oak Ridge National Laboratory will boost home energy efficiency through automated
control systems for heating and cooling units, lighting and other systems that access data such as outside air and room temperature, humidity,
light level and occupancy all at a fraction of a cost of typical wireless sensors you see on the market today.
A wireless light switch allows remote control of lamps for convenience; some lamps include a touch switch which electronically controls the lamp if touched anywhere.
You can also buy fluorescent black light bubbles, invisible black light ink, fluorescent black light carpet
and even fluorescent black light hair gel. If you have fully enclosed fixtures,
look in the ratings for LEDs that can be used in them;
many LEDs can't because high temperatures can shorten their life.
