It is the use of tides or wind to deliver our daily energy needs that form ‘Green Energy’. They are thought to be ‘Green’ due to the fact that they are easily restored and natural. Often by going back in time we see the value of wind power and windmills as modern energy sources. Regardless of this, we are mainly talking about using modern techniques to offer planet friendly and eco-efficient solutions.
Solar Thermal and Solar Water Heating Collectors are examples of what can be used in the house as part of renewable energy technologies. Following on it is items such as the Photovoltaic Panels (PV’s) that develop electricity through suitable roof-panels. Another key element is that of Biomass Energy, which relates to Stoves and Boilers burning Wood, Fuel and Pellets. There is the old heat from the Sun now known as Ground Source Heat Pumps. When we think about Wind Power and Hydropower we have two of the more habitual forms of energy generation.
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 Solar Energy Systems: This technology is based around two core types of knowledge to achieve the results known as Solar Energy. First, we have Solar Water Heating Collectors, which absorb energy from the Sun and transfer this into hot water. Whereas Solar Electrical panels or Photovoltaic heat collectors transfer solar radiation into electricity. Obviously situated away from blockages such as chimneys these Solar Panels basically need to be mounted on south facing roofs at an angle of 30 degrees from the horizontal.
For the UK this is often considered the most popular form of ‘Green Energy’. With the ability to provide almost half the annual need for hot water in the house then Solar Water heating systems is very important. The cost of fitting depends on whether you do it yourself – 500 to 1500 pounds or whether you get a professional fit in which it will cost between 2-5k overall.
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.)
‘Energy Crops’ such as Willow and Poplar play a major part in the process under the banner of Short Rotation Coppice (SRC). Of equal importance is the ability to produce dry matter and perennial grasses are very good for this. Equally significant within this practise sit Municipal and Agricultural waste products. To begin with Agricultural Waste is often produced as part of the agricultural process overall. Whereas Municipal Waste is derived from wood or food and can be used for biomass energy.
Systems Based On Geo-Thermal Energy: Used in the generation of warm water and electricity this energy mainly comes from the Sun and heats the Earth. Having a consistent ground temperature of around 12 degrees centigrade is fortunate for the UK as it allows both the heating and cooling of buildings. With four units replaced for every one unit of energy used these heat pumps are very effective. This system can go even further if energy efficient items such as wind turbines or solar electrical panels are used.
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.
Hydropower is a subject that suits the UK energy production system. Having said that the art of using energy from moving water, as like wind power is very traditional. Interestingly enough this type of energy production meets 2 percent of the UK electrical demand in total.
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.
It is down to the worldwide energy requirements that sees the growth in ‘Green Energy’. Considering this schemes laid out above the UK domestic market appears to be one of the core beneficiaries of this technology.
With the bulk of development work in the domestic field both the Plumbers and Electricians are set to capitalise in this area. You can now get a range of grants to support the growth of renewable energy ideas within the European market. Equally important is the role of gaining qualifications to install items that we have talked about. By mixing green training with those of electrical or plumbing you could cover both angles.
