James McCullum, MD of Carbon Ethics, explains in an interview on Harmonious Living: “In the UK, a company is encouraged to reduce their carbon, but sometimes they don’t know where to start...

So they can invest in a little company called SolarTech in South Africa.” An electric geyser requires one tonne of coal per year to keep a geyser at 57°C, resulting in 3.7 tonnes of CO2. For every solar geyser installed, CO2 emissions are reduced by that amount. “By 2015, SolarTech will have 60 licenses countrywide, each installing an average of 50 solar geysers per month, which is consistently 133,000 tonnes of CO2 reduction per annum,” says McCullum.
