Renewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed. Sunlight and wind, for example, are such sources that are constantly being ...

Unfortunately, much of this heat simply escapes into the atmosphere. Wouldn’t it be great if we could harness it to produce energy? My research has shown this would indeed be possible.

A group of European scientists has sought to combine PV-thermal (PVT) energy coupled with a heat pump (HP) and borehole thermal energy storage (BTES) for powering an Italian swine farm. “This ...
