There could be a rise in the number of people looking to carry out green upgrades to their kitchens if homeowners heed comments from a sustainable energy organisation.Sustain claims that responsibility for improving energy efficiency in a home needs to be the preserve of utilities companies, house builders and homeowners if new energy demands and thresholds are to be met.Gordon Miller, sustainability and communications director for the company, believes that more needs to be done.Everyone has to take responsibility for improving energy efficiency in homes, reducing CO2 emissions and in so doing contribute to the UKs legally binding commitment to reduce C02 emissions by 80 per cent by 2050, he adds.The news could also lead to an increase in the number of people looking to take advantage of innovative kitchen gadgets to help reduce their energy use.Earlier this month, appliance manufacturer Kenmore claimed that fixtures like kitchen sinks and taps should maximise the available space in the room.
