There are some great ideas here for ‘becoming green’. Becoming ISO accredited is most certainly a way of showing that you support greenliness, but aside from just showing you ‘support’ greenliness, actually taking measures that ‘make’ you green are most commonly associated with reflecting your green support, hence making considerable savings on your carbon footprint. Mentioned throughout this thread are some useful ideas on the small changes you can make, such as recycling, not printing emails etc but I fail to see much reference to many of the energy saving technologies out there. Voltage optimisation for example is a great way to reduce your carbon footprint as it ensures you are using the most appropriate voltage levels for the electrical start up of equipment. For those who haven’t heard of voltage optimisation before, as you may or may not know, the voltage supplied from the national grid is 242V whereas most electrical equipment manufactured for Europe and the UK is rated at 220V and may indeed operate at an even lower voltage. The problem with this is that you are more than likely being supplied a higher voltage than you need, and you are paying for it whether you want it or not. Aside from making savings on your carbon footprint, the installation of a voltage optimisation unit will also enable companies’ to make significant reductions in their electricity bills. At Powerstar we have helped a range of big brand companies significantly lower their carbon footprint and electricity bills.
