ON5 is named after the 5th energy - the one we don't use. According to the law of physics, energy comes from four sources: the atom, the sun, the moon and the earth.
The 5th energy is unused energy, unconsumed energy, energy saved - in its essence, it creates zero greenhouse gas (GHG) emissions and is free. ON5 aims to help people tap into this 5th energy by implementation energy efficiency through various tools - in order for them to help save money and the planet.
