What is the environmental aspect?  
     
 
One unit of REG IP-195 can save 1,000 cube meters of natural gas a year for the user. The burning of 1 cube meter natural gas will emit about 2.2 kg of equivalent green-house gases emissions. So an unit of REG IP-195 can reduce 2.2 tonnes of equivalent green-house gases emissions.

You may not necessarily choose REG solar products, but for the blue sky and white clouds of our future generations, you must use solar energy!
