well we are starting to do our bit here we are getting some solar panels (1KW with 2KW inverter) installed which should reduce the amount of co2 by about 1 Kg per 1KW we are producing from sun so on average we should be reducing our green house gas (co2) by 5 kg per day or 1500kg per year (apparently 300 days of good weather here) or when we get another 1KW of solar panels 10 kg per day or 3000kg per year

we are talking about making a compost some how here from kitchen scraps, lawn clippings ect in an effort to reduce the amount of methane we are producing but other then increasing the soil quality here i don't think it will make any difference to the amount of CH4 we are producing just changing location where methane is produced ?

we are also looking at collecting rain water for watering garden and maybe flushing toilet
