Energy
Energy and its Usage
• One third of all energy produced is consumed by domestic households.
• A UK household creates 6 tonnes of CO2 every year
• Electricity usage has doubled since the 1970’s
• ¾ of the UK electricity is generated by coal and gas plants.
Types of Renewable Energy

Stop And Think
• Think before you flick
• Top tips
• Remember
EVERYTHING WE DO, USE OR PURCHASE HAS AN ENERGY COST
Construction
Improving the quality and sustainability of construction is not merely about using greater resource for delivery or efficiency.
It is about getting it right from the start, having the skills in place at all points in the development chain.
Government aims• Greater uptake of training programmes,
improving skills and increasing retention rates of skilled workers within a safer industry;
• Reduced carbon footprint of activities and better use of resources;
• Development of voluntary agreements and initiatives by the construction industry and its clients with the aim of reducing the carbon footprint and use of resources within the built environment.

Using Recycled materialsWestlea Integer Homes Cherhill, Wiltshire is a pilot development by a social landlord of two family houses. The project demonstrates a high level of sustainability and incorporates a number of 'green' features including a range of reclaimed and recycled materials.
Reclaimed bricks, Recycled Pulverised Fuel Ash, Recycled newspaper insulation Recycled plastic, Railway sleepers/ telegraph poles Crushed concrete from demolition Timber salvaged from demolition
Waste
What is Waste?
How Much do we Waste?
• Household Waste: 2005/2006 28.7 million tonnes, 78% not recycled
• Energy: one third wasted every year, amounting to £7.5 billion, £3 billion on electricity alone.
• Water: 2005 groundwater levels lowest for 20 years, 50% more water used than 25 years ago.
Why Should we Cut our Waste?
• Ensuring the future of energy supplies
• Reducing landfill and helping to curb climate change
• Keeping energy affordable
• Preserving water and protecting wildlife
Tackling Household Waste
• Composting waste
• Recycling
• Energy from waste
Tackling Energy Waste
• Renewable energy
• Insulation
• Thinking about your actions
Tackling Water Waste
• Recycle rain water
• Be more aware of what you are using
• Use less water
Carbon Footprint
What is a Carbon Footprint?
Your carbon footprint is the amount of CO2 that enters the atmosphere because of the electricity and fuel you use and the products you buy.
It is measured in tonnes of CO2.
What is a Carbon Footprint?
Your carbon footprint mostly depends on: • how much energy you use to heat your
home • the electronics and appliances you use • what kind of transport you use day-to-day
(Energy Saving Trust, 2008)
Heating your Home
Boilers account for around 60% of the CO2 emissions in a gas heated home
Sustainable Renewable Energy•Ground source heat pumps
•Solar water heating
•Biofuel
Heating your HomeTips to Reduce your Carbon Footprint
• Condensing boilers• Insulate your hot water tank• Double Glazing• Turn your thermostat down• Radiators• Insulation• Draught Proofing
Electronics and Appliances
• CFC (Chlorofluorocarbon) free appliances• DAB radios & Eco-kettles• Look out for the Logo• Energy saving light bulbs• Switch to a renewable
electricity supplier.
Location• Proximity to services/amenities
• Access to public transport
Sustainability is not a matter of fashion, it has become a matter of survival.
