Micro wind turbineProduces electricity whenBlades are turned by wind,Which is then stored in abattery
Photovoltaic electricityPanels of solar cells made ofSilicon, turn the sun’s lightInto electricity
Solar water heatingWarms water directly from thesun’s rays which can be storedIn a tank
Loft insulationThe easiest-to-installand most cost-effectivehome energy efficiencymeasure
Compost heapAnother way of preventing organic waste such as food from going to rubbish dumps
Ventilation with heatrecoveryHeat generated in one part of the house isused to warm fresh air being delivered to another
Double glazingTwo panes of glassseveral millimetresapart keep heat inand save a lot ofenergy
Smart metersTell exactly how much electricity you’re using ata given moment (and the cost)
Micro combined heat and power systemSaves and uses the heatproduced in electricity generation,which is otherwise lost
Cavity wall insulationFills the air gap betweenInner and outer walls of theHouse with insulating material

Background to Energy Act 2011
• 20% cut in emissions from existing homes by 2020• 13% cut in emissions from non-domestic buildings by 2020• Zero carbon new homes by 2016• Zero carbon non-domestic buildings by 2019• Smart meters• Carbon capture from fossil fuel power stations• Bigger smarter grid• Encourage renewable energy sources by
supporting feed in tariffs• A new financing framework funded
via energy bills: The Green Deal
Who pays? How Funded?The Energy Act 2011 – The Green Deal
N.B. ECO provide support for hard to treat homes and fuel poverty
The Golden Rule
The Green Deal Programme
• English House Survey 2010•(English House Survey 2011)
Consumer research suggests that there are a number of practical barriers: the upfront cost of measures, the length of time required for measures to pay back in savings and the ‘hassle’ involved in planning and carrying out work.
