Which DNA Testing Company Should I Use? The answer, as in many areas of genealogy, is it depends. Because different people test with different companies, many of which maintain their own databases of tested individuals, you will achieve the greatest chance of useful matches by either being tested, or sharing your DNA results, with as many companies as possible.
Cogeneration / Combined heat and Power (CHP) Cogeneration (cogen) through combined heat and power (CHP) is the simultaneous production of electricity with the recovery and utilisation heat.
Basics of Cogeneration. In most thermal power plants more than half of the thermal energy released from burning fuel is not exploited for electricity generation but is lost as excess heat due to the fundamental laws of thermodynamics. In cold climates, cogeneration is one of the most cost-beneficial techniques of lowering carbon emissions for heating. 2  Due to the proximity of CHP plants to where the power is needed, massive production outages are less probable.
