When our daily energy requirements are met by ‘Green Energy’, then we are using resources such as wind, tides or geothermal heat. They are considered ‘Green’ because they are environmentally friendly. When considering elements such as Wind Power and Windmills, in many cases we are looking back at the history of energy production. Regardless of this, we are mainly talking about using modern techniques to offer planet friendly and eco-efficient solutions.

In the home environment, one can see examples such as Solar Thermal and Solar Water Heating Collectors. For electricity created through roof-installed panels, you would need Photovoltaic Panels or PV’s. Equally important is that of Biomass Energy – which includes Stoves, Fuel, Pellets and Boilers burning Wood. Then we have the ancient energy of the Sun and the heat that comes from it – now called Ground Source Heat Pumps. Finally, we have two of the most traditional forms of energy generation that have gone through some resurgence over the last few years; these being Wind Power, Wind Turbines and Hydropower (including Water Wheels.)

Solar Thermal Energy – By using different technologies, Solar Energy is effectively made up of two types of solar panels. 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. 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.

With Solar Power being so common within the UK, it’s Solar Water Power that is most often used. Solar Water heating systems can meet the need for more than half of all hot water needs in the domestic market. The average cost of installing this type of equipment is expected to range from 500 to 1500 pounds for a DIY system, through to 2-5k for a professionally installed system.

Biomass Energy Systems – Including all natural energy forms derived from plant and animal products – such as wood, straw, poultry litter and ‘energy crops’. Considering its ability to produce energy in the form of heat and electricity, this type of energy is extremely flexible. 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. It should be borne in mind that the whole process is designed to produce energy without an impact on CO2. Having a tree planted in place of another (that is felled for energy production) helps overall.

To meet the need, fast growing trees, known as Short Rotation Coppice (SRC) are utilised. Perennial grasses are also responsible for large quantities of dry matter. Within this process also sits the lesser known Agricultural and Municipal Wastes. To begin with, Agricultural Waste is often produced as part of the agricultural process overall. However, waste derived from food or wood is another biomass entity – called Municipal Waste.

Geo-Thermal Energy Technology: This is primarily the heating of the Earth (mainly from the sun) and can be utilised in electricity and warm water production. In the UK, we are lucky that we can both heat and cool buildings from the ground source temperature of around 12 degrees. 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. The energy generated by a heat source pump can in fact be considered 100 percent renewable, if the power to operate the pump comes from solar electrical panels or a wind turbine.

Wind Energy – An Update On Old Technology: The use of wind as a source of energy has been going on for thousands of years, especially in milling grain and pumping water. More recently, there has been the desire to deliver the energy created to the home – or to a local power grid. With regard to wind generation, it is the UK that has the highest production within Europe. Although we only utilise 1 percent of the current electricity capability from wind – we do have the ability to create 10 percent. Frankly, electricity can be realised from as little as 2p per kWh – as opposed to the current level of 2-10 p per kWh. The financial recovery process takes around 6-9 months.

Within the UK, Hydropower suits the energy generation model. Just like a thousand years ago, we are utilising the energy from water. That aside, it is fair to say that some 2 percent of the UK’s electrical load could come from this source.

Using a turbine, a Hydropower system can transform the energy of water into other forms. It is by either water ‘drop-offs’, or Natural River runs, that turbines can work through this process. ‘Micro-Hydro’ utilises a chunk of the outdated sluices and dam systems that have been killed off by the large national distribution methods. This smaller form of electrical output has been recently reviewed and could allocate some 200MW of capacity to the UK system. The capital cost of installing a micro-hydro system can run between 200 and 3000 pounds per kW of energy output.

Because of the energy need of the Western World, we are now seeing a rapid rise in ‘Green Energy’. The UK domestic market appears to be one of the core beneficiaries of this technology.

Electricians and Plumbers in particular are expected to provide the main thrust of domestic installation expertise. 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. Gaining installation certification across these areas can only provide further opportunity and job security to anyone already in related fields or looking to retrain. By mixing green training with those of electrical or plumbing, you could cover both angles.
