Explaining Solar PV Training - Where To Go

In a nutshell, 'Green Energy' utilises natural resources such as sunlight, wind, tides and geothermal heat to provide our daily energy requirement. They are considered 'Green' because they are environmentally friendly. It is easy to think that we may be travelling back in time when we think of items such as wind power and windmills. However, it is the result of eco-efficient and planet friendly options that this process is maintained.

In the home environment, one can see examples such as Solar Thermal and Solar Water Heating Collectors. Moving on from this there are the Photovoltaic Panels (PV's) which can generate electricity from your roof. Equally important is that of Biomass Energy - which includes Stoves, Fuel, Pellets and Boilers burning Wood. We now also have Ground Source Heat Pumps - which draw out the heat left by the Sun. Not all 'Green Energy' is new - by considering Wind Power and Hydropower we are looking at some of the oldest forms of energy production.

Thermal Energy Systems: This technology is based around two core types of system. Firstly, there are elements that absorb energy from the sun and create hot water - known as Solar Water Heating Collectors. Added to this is the generation of electricity from solar radiation - known as Photovoltaism, or more commonly 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.

Within Solar Energy overall, Solar Water Power is most commonly used in the UK. With the capacity to deliver 50 percent plus of a household's hot water requirement annually, Solar Water heating systems are crucial to energy in the UK. Typically, to fit this type of equipment will cost between 500 and 1500 pounds for a DIY kit - all the way up to 2-5k for a full professional fitting.

Biomass Energy Systems - Including all natural energy forms derived from plant and animal products - such as wood, straw, poultry litter and 'energy crops'. It is extremely useful - in that it can produce a range of power sources, including heat and electricity. Indeed, within the European Markets, the UK has some of the leading levels of Biomass material at hand. Considering all this, and the relative lack of C02 produced, makes the whole process highly green overall. Because the system often involves one tree being planted as another is felled, many wood crops are deemed to be sustainable sources.

Within this field is the need for the use of 'Energy Crops', such as fast growing trees, e.g. Willow and Poplar or other entities grown on a Short Rotation Coppice (SRC). Of equal importance is the production of perennial grasses - because of their yield of dry matter. Other less known materials within this field are Agricultural and Municipal Waste. To begin with, Agricultural Waste is often produced as part of the agricultural process overall. Municipal Waste such as food or wood can also be utilised as a biomass product.

Systems Based On Geo-Thermal Energy: By naturally heating the Earth, the Sun has the potential to generate both warm water and electricity. Using the ground temperature of around 12 degrees in the UK - we can both heat and cool buildings. 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. 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: When you consider the milling of grain and pumping of water, it is easy to see how long wind energy has been with us. Whether to your home or to a local grid, when the energy has been generated it must be delivered to a point of usage - and cannot be stored. To be fair, the UK has the highest level of wind generation within Europe. It is interesting to note that whilst we can produce 10 percent of our entire power requirement from wind power, at present we only produce 1 percent. Rather than electricity production running at 2-10 p per kWh, it could be run at 2p per kWh. Therefore, recovery of cost takes approximately 6-9 months overall.

Finally, we have Hydropower; an area in which the UK does well within Europe. The ability to utilise energy from moving water, much like wind power, has been going on for thousands of years. It is this type of energy production that could meet 2 percent of all the UK's demand.

Using a turbine, a Hydropower system can transform the energy of water into other forms. No water reservoirs are required - as the turbines either run through a water drop-off system or the natural power of the river. It is by using the eroded national distribution systems, that allows for outdated sluices and dams to be used by techniques known as 'Micro-Hydro'. Having said that, this process could still generate 200mW of the National Capacity. When considering the installation cost of items such as this, we're looking at somewhere between 200 pounds and 3k per kW of energy created.

Because of the energy need of the Western World, we are now seeing a rapid rise in 'Green Energy'. The UK is very well placed to provide most of the schemes set out above, and the UK domestic market again is one of the key beneficiaries of this technology.

Electrician and Plumbers are thought to be key in providing expertise during domestic installations. It is the political view of this type of energy generation that results in grants and financial aid becoming ever-more prevalent. Gaining installation certification across these areas can only provide further opportunity and job security to anyone already in related fields or looking to retrain. To cover both ends, you could consider electrical or plumbing training along with green systems.
