Editor's Notes

1. Photovoltaic Solar Panels convert Photon particles from the sun directly into electricity. CO2 emissions Virtually none during operation. Solar Thermal Collectors generally do not generate the electricity required in a household to provide lighting, charge electrical equipment or to power appliances. However, they can provide a good supply of hot water for heating or washing, greatly reducing a household's gas or electricity requirements. Running costs Virtually none, a small electric pump is usually required. CO2 emissions Virtually none during operation. Can reduce household emissions by 260kg CO2 per year when replacing gas heating.
2. The modern wind turbine is quiet and is available in different sizes, depending on the required output. A small unit can attach directly to the roof and larger units require their own support post. Energy availability Dependent upon wind speeds which fluctuate throughout the day and are often lower in spring/summer than autumn/winter. Also very dependent on site. The output of a wind turbine is determined by the wind speed at the site of the turbine, which depends on the location, height, and nearby obstructions. 
3. It is estimated that 29% of carbon dioxide emissions are a direct result of transport. Hydrogen cars are powered by hydrogen fuel cells. The cell is topped up with liquid hydrogen, which mixes with oxygen from the air to produce electricity and steam.  Electric cars are only as eco friendly as the electricity that powers them. if the electricity was generated by sustainable methods, i.e. solar, wind or tidal, then the electric car is a truly eco friendly mode of transport. Biofuels can be manufactured using various crops such as Oil seed Rape.  These fuels are non carbon emitting and so do not contribute to global warming Walking or cycling could contribute to lowering greenhouse gas emissions. 
4. Insulating your home is usually the most cost effective way to keep warm, cut your heating bills and reduce your carbon footprint  While cavity wall and loft insulation can represent a significant financial outlay, there are other cheaper, common sense things that we all can do to improve the insulation of our homes.
5. Installing double glazing can cut heat loss through windows by half. If you can't afford to replace all the windows, why not choose the rooms that cost you the most to heat. Heavy curtains, drawn at night, and draft excluders can reduce the the heat lost to your house considerably Solar windows are coated in a transparent dye which captures, concentrates and redirects light along the surface of the glass to photovoltaic cells in the frame, which convert the light into electricity. The system can produce a tenfold increase in power output compared to use of the photo voltaic cell alone.
6. A heat pump makes use of the higher temperatures underground (between 8°C and 13°C) to heat from water in pipes which are then be circulated through a heating system. As the fluid passes through the house it looses some of its heat and so is re-circulated back through the ground where it will absorb more heat before being passed through the heat pump again. Electric air-source heat pumps are often used in moderate climates.  They use the difference between outdoor air temperatures and indoor air temperatures to cool or heat a home. While air-source pumps are usually not quite as efficient as ground source the technology is improving all the time and some models are able to provide 320% efficiencies compared to 400% for a ground source pump.
7. A Greenhouse is ideal for growing a wide variety of fruit and vedge, throughout the year, reducing your households reliance on air freighted high carbon supermarket food. Composting household food waste is an excellent way to increase the yeilds from your garden produce, thus reducing your reliance on over packaged groceries with a high carbon footprint, not to mention your weekly spend. 
8. When installing solar thermal panels or heat pumps households will require a different cylinder to those traditionally used in the home to store hot water. Rainwater collection is one of the simplest and most energy efficient ways of saving water. A household can use filtered rainwater to flush toilets, wash clothes, clean the car and other outside cleaning. According to experts approximately 30% of our water is flushed down the toilet.One of the main reasons for this is the number of water inefficient toilets being used. Eco friendly toilets reduce the amount of water used per flush to between 2 - 4 litres by using innovative dual flush technology which vastly reduces the amount of water required for the ‘perfect' flush by up to 60%.
