It is the use of tides or wind to deliver our daily energy needs that form ‘Green Energy’. When ‘Green’, they are all thought to be replenishable and natural. It’s interesting to note that in some instances we’re actually travelling back in time to utilise some of the older energy skill sets e.g. Wind Power (Windmills etc.) Overall, this is the method of using modern techniques to provide eco-efficiency and planet friendly options.

It is the use of simple renewable energies such as Solar Thermal and Solar Water Heating Collectors, that suits the home environment. It is equipment such as Photovoltaic Panels (PV’s) that develop electricity through suitable roof-panels. Biomass Energy is the next phase, and this involves Fuel, Pellets, Stoves and Boilers burning Wood. Of course, then there is the heating from the Sun – often just called Ground Source Heat Pumps. When we think about Wind Power and Hydropower we have two of the more common forms of energy generation.

Solar Energy Systems: Often called Solar Energy, this is fact based on two types of solar panels each using different ideas to get their results. Initially, there is the process of obtaining hot water from the Sun via Solar Water Heating Collectors. Additionally, there is the method of converting solar radiation into electricity known as Photovoltaic – or simply Solar Electrical panels. Solar Panels themselves need to be away from all light blocks, and should be on south facing roofs at angles of 30 degrees from the horizontal plane.

As a result, Solar Water Power is often considered the most common form of Solar Energy in the UK. Solar Water heating systems are extremely important – and can provide over half of the hot water needs for houses within the UK. The cost of fitting depends on whether you do it yourself (500 to 1500 pounds) or whether you get a professional fitter – in which case it will cost between 2-5k overall.

Biomass Energy Systems – Including all natural energy forms derived from plant and animal products – such as wood, straw, poultry litter and ‘energy crops’. It is extremely useful – in that it can produce a range of power sources, including heat and electricity. Indeed, within the European Markets, the UK has some of the leading levels of Biomass material at hand. Considering all this, and the relative lack of C02 produced, makes the whole process highly green overall. Because the system often involves one tree being planted as another is felled, many wood crops are deemed to be sustainable sources.

‘Energy Crops’ trees such as Willow and Poplar play a major part in the process – under the banner of Short Rotation Coppice (SRC). Perennial grasses also produce a high yield of dry matter. Within this process also sits the lesser known Agricultural and Municipal Wastes. Agricultural Waste is commonly formed as a by-product of traditional agricultural work. Another biomass source is that of municipal waste – and this comes from recycled wood or food.

Systems Based On Geo-Thermal Energy: By naturally heating the Earth, the Sun has the potential to generate both warm water and electricity. Using the ground temperature of around 12 degrees in the UK – we can both heat and cool buildings. These heat pumps do need some power to operate; but for every one unit of energy they use, they generate four units of energy in return. This system can go even further – if energy efficient items such as wind turbines or solar electrical panels are used.

Wind Energy: As an energy source, wind energy has to be one of the oldest forms of energy creation in history. That aside, the ability to generate energy and both transfer this into the home or the local grid has been a relatively new option. With regard to wind generation, it is the UK that has the highest production within Europe. For the fact remains that, within the UK, we have the ability to generate 10 percent of our requirement from Wind Production – as opposed to the current value of only 1 percent. Electricity can be produced from as little as 2p per kWh, but generally comes in somewhere between 2-10p per kWh. The financial recovery process takes around 6-9 months.

Then there is Hydropower – something within Europe that the UK excels in. Although new in its approach, the act of harnessing energy from water has been going on for a long time. In total, this could produce something like 2 percent of all electricity required in the UK.

By using a turbine, a Hydropower system can transfer the kinetic energy of moving water into another form. Turbines use either a water drop (e.g. through a dam) or by a natural ‘run of the river’ – thereby having no water storage reservoir. ‘Micro-Hydro’ however utilises old outdated sluices and dams. Although a lesser known form of electricity output, this process could supply 200mW of UK demand. The expected cost of installing a system such as this would be between 200 pounds and 3k per kW of output.

‘Green Energy’ is growing – mainly due to the demands of the Western World. To be fair, the UK domestic market is actually leading the resurgence, with a variety of schemes.

It is the drive for installations in the domestic sector that looks to favour jobs such as plumbers and electricians. With EEC and UK recognition of renewable energy getting ever-higher on the political agenda, the grants and financial aid for introduction of these systems can only increase. It is by gaining the right certificates that will provide opportunities and job security for the long term. Look for combined electrical and plumbing training, with a key emphasis on practical green systems and installation.
