Best Strength

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 environment for example encompasses a range of energy ideas including Solar Thermal and Solar Water Heating solutions. Next on the list you would find the actual solar electricity Photovoltaic Panels (PV’s) – which basically generate electricity through roof-installed panels. A further factor resolves around stoves and boilers which are known as Biomass Energy. We now also have Ground Source Heat Pumps which is simply the heat from the Sun. Considering items such as Wind Power and Hydro Turbines we are finally getting to very old forms of energy production.

Through a brief review of each we can look at those wanting to train and work in this area and the skills that they will need. Considering the points raised so far, this is expected to be somewhere in the domain of the Plumber, the Gas Engineer and the Electrician. It would be worth gathering information from as many different sources as possible, so check out our other pages on Electrical, Green and Plumbing careers. So it is worth checking out the sites for a variety of training providers as a result bookmark (CTRL-D) this page so you can come back.

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.

Systems Utilising Biomass Energy: Although in the modern world this now includes ‘Energy Crops’ it also takes in suitable plant and animal substances. Due to its adaptability it can produce a range of energy forms from heat and electricity through to combinations of both. It is interesting to note that the UK has some of the largest quantities of Biomass material to generate electricity within Europe. One of the main factors of this style of energy is the result without the impact on C02. With each tree being planted as another is felled you can see how the C02 produced during heating is minimised and why the system is deemed sustainable.

A process titles Short Rotation Coppice (SRC) such as Willow and Poplar are used to meet the demands of such ‘Energy Crops’. Perennial grasses are also responsible for large quantities of dry matter. Of equal importance, although maybe less well known are Municipal and Agricultural Waste. Using normal agricultural activity, Agricultural waste is a natural by-product. Another biomass element is that called municipal waste and this comes from wood or food goods.

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.

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.

By using a turbine a Hydropower system can transfer the kinetic energy of moving water into another form. By using a dam or a natural river process these turbines do not require water storage. Alternatively ‘Micro-Hydro’ systems use hitherto outdated sluices and dams to generate electricity. This process alone could meet 200mW of the UK requirement. When considering the install cost of items such as this it is worthwhile to think about the return which rests somewhere between 200 pounds and 3k per kW of energy created.

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 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.
