Comparing Solar Energy Classes Across The UK

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.

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.

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 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.

It is the drive for installations in the domestic sector that looks to favour jobs such as plumbers and electricians. 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. As a new industry, there are a range of new certificates to gain whether new or coming to this industry from a likeminded source. Training such as electrical or plumbing that incorporates green technology would be very useful for the future.
