Catherine and her colleagues at the University of Oxford have developed two pieces of software; IMeasure for use at home, and SMEasure for use in schools and businesses. By inputting data from your gas and electricity meters, the software calculates kilowatt hours (kW.h) of energy used, kilograms of Carbon Dioxide emitted and money spent for a particular period of energy use. It's a great way to look at patterns in energy use and monitor what effects your energy-saving measures, such as a changing to energy-saving bulbs, are having. You can register to use the software online. It's free and you'll also be taking part in one of Catherine's research projects.
