A 2.5Kw system can save 1-2 tonnes of C02 and £150 - £250 per year. A 6kW system can save 2.5 - 5 tonnes C02 and £250 - £450 per year.
Turbines can have a life of up to 20 years but require service checks every few years to ensure they work efficiently. For battery storage systems, typical battery life is around 6-10 years, depending on the type, so batteries may have to be replaced at some point in the system's life.

Double Glazing
Installing double glazing throughput your house is something everybody can do and will reduce the amount of heat lost through windows by 50% and save you £80 to £100 pound a year and reducing your Carbon Footprint by up to 680kg per year. See www.energysavingtrust.org.uk - Rozza
Solar PV (Photovoltaic Cells)
Solar PV requires daylight (direct sunlight is not needed for them to work) and can generate electricity to power lights and appliances even on a cloudy day. System costs can vary depending on size of installation from £4000 and can be either panels or tiles depending on budget and positioning. Some maintenance will be required. Up to 800kg of CO2 emissions and about £125 a year on bills can be saved. See www.energysavingtrust.org.uk - Rozza
Solar Water Heating
Solar Water Heating installations utilise the heat from the sun to by absorbing it and then transferring it to your water heating system. A typical system can supply nearly all your hot water during the summer months and roughly one third all year round. Reductions in CO2 emissions could be around 350kg-450kg per year and £50 off your heating bills depending on the fuel replaced. See www.energysavingtrust.org.uk - Rozza
Hydro Power
Hydro Power systems can generate surprising amounts of energy from a stream using a running water turbine which converts the potential energy stored in the water held at a height into kinetic energy and then electricity. This kind of system can be expensive to install but the power generated is free and creates no CO2. See www.energysavingtrust.org.uk - Rozza
Ground Source Heat Pumps
Ground Source Heat Pumps use an antifreeze/water mixture in buried looped pipes buried in the ground to absorb stored heat and transfer it into a building and can be used to heat rooms or water. There is no fuel used so no CO2 release. A typical 6-8kW installation costs £6'500 to £11'500 and can save up to £650 - £750 a year on bills and 4.5 - 5.5 tonnes of CO2. See www.energysavingtrust.org.uk - Rozza
Install a Biomass Boiler
Biomass is basically wood and energy crops such as sugar cane and maize. Burning it is Carbon Neutral as the amount of carbon release is the same as the amount of carbon absorbed when the crop was growing. Using locally sourced fuel is the best option as it will be cheaper and involve less transport miles and help support your local economy. A typical 15kW pellet boiler which is probably enough for an average 3/4 bed house will cost £5'000-£11'000 and could save up to £350 a year in bills and 6 to 7 tonnes of CO2 a year.

Install a Wood Burning Stove
Wood Burning Stoves typically have an output of 6-12kW and can be fuelled by logs, wood pellets, waste paper (especially if you have a paper log maker). Some stoves can be fitted with a back boiler. This can dramatically reduce heating costs and your carbon output as its Carbon Neutral. See www.energysavingtrust.org.uk or www.biomassenergycentre.org.uk - Rozza
