Micro Energy Generation

It is estimated that normal domestic homes are responsible for 27% of total carbon dioxide emissions, with each house producing 6 tonnes of CO2 a year.
1.7 tonnes of which is from electricity
4.3 tonnes is from our consumption of gas
One strategy to address these figures is to use less energy, improving our household insulation and recycling. Another complimentary strategy is that of micro power generation, whereby each household sustainably generates their portion, or all, of their own electric and power supply to provide heat or light, and ideally, generates a surplus which they can sell back to the national power suppliers.
There are a number of ways in which households can achieve this:
Solar panels
Wind turbines
Geothermal energy
Bio dung
