When our daily energy requirements are met by ‘Green Energy’, then we are using resources such as wind, tides or geothermal heat. They are thought to be ‘Green’ due to the fact that they are easily restored and natural. When considering elements such as Wind Power and Windmills, in many cases we are looking back at the history of energy production. This idea is preserved by the use of technology, eco-efficient options and planet friendly alternatives.

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.

Thermal Energy Systems: This technology is based around two core types of system. Firstly, there are elements that absorb energy from the sun and create hot water - known as Solar Water Heating Collectors. Added to this is the generation of electricity from solar radiation - known as Photovoltaism, or more commonly Solar Electrical panels. To get the best results these panels need to be south facing at an angle of around 30 degrees from horizontal, and away from blockages.

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 Based Systems: This is a general term for all forms of plant and animal material e.g. wood, straw, poultry litter and ‘energy crops’. It’s the ability of this power source to generate diverse forms of energy, such as heat and electricity, that makes this so adaptable. The ability to generate electricity is one of the UK’s main green strengths - as it has one of the larger Biomass legacies within Europe. Added to all this, is the lack of C02 produced as a by-product of the whole process. Having a tree planted in place of another (that is felled for energy production) helps overall.

‘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.

Because of the energy need of the Western World, we are now seeing a rapid rise in ‘Green Energy’. The UK is very well placed to provide most of the schemes set out above, and the UK domestic market again is one of the key beneficiaries of this technology.

Electrician and Plumbers are thought to be key in providing expertise during domestic installations. It is the political view of this type of energy generation that results in grants and financial aid becoming ever-more prevalent. Gaining installation certification across these areas can only provide further opportunity and job security to anyone already in related fields or looking to retrain. To cover both ends, you could consider electrical or plumbing training along with green systems.
