ABSTRACT
Wind turbines, solar electricity and solar hot water are all possibilities for avoiding emissions at home (or, indeed, at work). Precise figures depend upon location and upon the orientation of the house. the first generation of home wind turbines have not proved as reliable or as trouble free as their manufacturers expected, but may still eventually produce enough electricity per year to offset at least 1 tonne of emissions – although at a much higher cost per tonne than investing in a large-scale commercial wind farm. Solar hot water is now a well-established technology, particularly in sunnier countries, and even in the UK can cut household emissions by 0.5 tonnes or more a year. Savings from solar photovoltaics can be greater than this, although the amount depends crucially upon the area of panels that are installed.
