When our daily energy requirements are met by ‘Green Energy’ then we utilise items such as wind, tides or geothermal heat. ‘Green’ basically means that all the energy is renewable. 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 areas such as eco-effiency and planet friendly options.

The home can use a range of new ideas to help with energy usage including Solar Thermal and Solar Water Heating Collectors. Equally there is the basic electricity generated through roof-installed panels. 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 come it – now often called Ground Source Heat Pumps. At the end there are two of the most mature forms of energy methods in the UK albeit renamed as Wind Turbines and Hydropower.

Looking at each area in turn we will consider some of the skills needed by those who want to train in this field. If you currently work in the areas of Electrical, Gas and Plumbing then this could be appealing to you. Certainly by getting information from many sources we can look at the career potential for Electricians, Gas and Plumbers. We’ve also provided links and adverts from several training providers, so book-mark this page (CTRL-D) and you can come back later to review other options.

Thermal Energy Systems: Often called Solar Energy, this is fact based on two types of solar panels each using different ideas to get their results. Making hot water from solar energy is the first stage and is known as Solar Water Heating Collection. Secondly, Photovoltaic heat collectors – often simply referred to as Solar Electrical Panels – which transform the solar radiation into electricity. Across the board, Solar Panels should be mounted on a south facing roof, at an angle of 30 degrees away from horizontal, and to some extent away from blocking trees, surrounding buildings and chimneys.

Within Solar Energy overall, Solar Water Power is now commonly used in the UK. Solar Water heating systems can provide over 50 percent of a household’s hot water requirement during the year. 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 and ‘Energy Crops’ – This is a general term for all forms of plant and animal material e.g. 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 concepts 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. To that end, many wood crops come from sustainable sources (as one tree is felled, another is planted in its place; thus the new tree absorbs the CO2 produced during the heating process.)

By the growth of Short Rotation Crops (SRC) the UK is able to maximise the ‘Energy Crops’ return against the plant production overall. Of equal importance is the production of perennial grasses because of their yield of dry matter. Whilst Agricultural and Municipal waste may appear lesser known they are essential to the whole process. Agricultural Waste is commonly formed as a by-product of traditional work in agriculture. Because it comes from food or wood Municipal Waste is also considered a useful biomass product.

Systems Using Geo-Thermal Energy – This is primarily the heating of the Earth (mainly from the sun) and can be utilised in electricity and warm water production. Using the ground temperature of around 12 degrees in the UK we can both heat and cool buildings. Whilst these heat pumps require energy to operate their rate of return is excellent being four units kept for every one unit of energy used. 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.

Systems Based On Wind Energy: As an energy source wind energy has to be one of the oldest forms of energy creation in history. Whether to a home or local grid when the energy has been generated it must be delivered to appoint if usage and cannot be stored. The UK alone is considered one of the best sources of wind generation 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 1 percent. Instead of producing electricity at a rate of 2-10p per kWh we could be generating at 2p per kWh. Because of this it is estimated that it takes between half a year to three quarters of a year to cover the costs.

Finally, we have Hydropower; an area in which the UK does well within Europe. Just like a thousand years ago we are looking utilising energy from water. That aside it is fair to say that some 2 percent of the UK’s electrical load comes from this source.

It is a Hydropower process, using a turbine that can convert the energy from one for into another. It is by either water drops or Natural River runs that turbines can work through this process ‘Micro-Hydro’ however avoids this system killed off by the larger national distribution methods and plans to use the outdated sluices and dams. This smaller form of electrical output has been recently reviewed and could allocate some 200MW of capacity to the UK system. The expected cost of installing a system such as this would be between 200 pounds and 3k per kW of output.

The demand on ‘Green Energy’ continues to develop in light of the energy demands worldwide. That said the UK is well placed, especially in the domestic sector to take full advantage of the various items above.

With the rise in demand for domestic installations both Electricians and Plumbers are well placed to take advantage of this technology. Not only in the EEC but also in the UK ‘Green Energy’ is rapidly gaining ground as the way forward and a range of financial incentives are in place to support this. It is by gaining the right certificates across the board that will help opportunities and job security for the long term. To that end it may be worth thinking about combined training where you can get plumbing or electrical training along with green knowledge.
