RENEWABLE ENERGY SOURCES IN YOUR DESIGN

If you are thinking about renewable energy technologies for your home there are a number of different solutions available. This is a brief guide to the different types of technology that is currently available.


Renewables are really starting to become realistic alternatives to traditional power and heating solutions. When we think of green energy most of us will think of solar and wind power. You have probably seen the large white wind turbines whilst driving and solar panels on peoples roofs.

There are however a number of other ways to get the green energy that indirectly use the Sun's solar energy. Indirect solutions are great because they do not rely on the Sun being out and blazing directly onto our solar panels. It does not need it to be a windy day as with wind turbines. Instead indirect solar takes the Suns stored energy from the air, ground, and water.


Micro wind power uses a small turbine either in your garden or on your roof. On windy days the turbine will generate electricity and contribute towards reducing your electricity demand from your supplier and thus save on electric bills. They are a great partner to solar PV panels as it is usually either windy or sunny or both.

Solar photovoltaic or solar PV is like solar thermal except rather than heat water they turn the Sun's light into electricity. A typical installation will cover a large proportion of the roof of a typical house. They work best in direct sunlight but also produce electricity even on cloudy days.

Ground source heat pumps work on the same principle as air source except they get their energy from the ground. Cables are buried in your garden that extracts heat from the ground and pumps it into the home. The energy is typically used to power underfloor heating.


Micro-hydro and water source heat pumps get their power from running water such as a stream. Micro-hydro produces electrical power whilst water source heat pumps produce heat. You, of course, need to have your house very close to a river for this to be a valid option.

Micro combined heat and power of CHP systems look pretty much like an ordinary gas boiler. The difference is that they also produce your electricity. This may not sound much like renewable technology but they are very efficient and therefore save carbon compared to conventional systems.

Finally, there is biomass. This is probably the least used in domestic situations. In simple terms it is much like your gas boiler except rather than burning gas it burns specially prepared pellets. These pellets are usually wood-based and are designed so that they can be automatically fed into the boiler much like gas is.

So there is the roundup of the currently available technologies that you could be using at home. You can use a combination of these systems as many alternative technologies complement each other.
