The Options For Solar Panel Courses Around 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. If we think of some of the older energy skills e.g. Wind Power, then in many ways we are going back in time. But in the main, this is the process of utilising modern technology to provide eco-efficient and planet-friendly alternatives.
In the home environment, one can see examples such as Solar Thermal and Solar Water Heating Collectors. Next on the list you would find the actual solar electricity Photovoltaic Panels (PV’s) – which basically generate electricity through roof-installed panels. Biomass Energy is the next phase, and this involves Fuel, Pellets, Stoves and Boilers burning Wood. Then there are the Ground Source Heat Pumps, which is simply the ground heat created 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.
Solar Thermal Energy Systems – Also known as Solar Energy, this mainly uses two, albeit different types of solar panels to get the desired 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.
In the UK, Solar Water Power is now one of the most sought after forms of Solar Energy. These systems are very efficient – and can deliver 50 percent of a household’s hot water requirement annually. Getting a professional fitting will cost around 2-5k, however, doing the job yourself could make it as low as 500 to 1500 pounds in total.
Biomass Energy Based Systems: 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. It is a useful point to make that the UK is one of the major producers of Biomass fuels within Europe. Added to all this, is the lack of C02 produced as a by-product of the whole process. Because the system often involves one tree being planted as another is felled, many wood crops are deemed to be sustainable sources.
A process called Short Rotation Coppice (SRC), utilising trees such as Willow and Poplar, is used to meet the demands of such ‘Energy Crops’. Perennial grasses also produce a high yield of dry matter. Whilst Agricultural and Municipal waste may be lesser known, they are essential to the whole process. To begin with, Agricultural Waste is often produced as part of the agricultural process overall. Another biomass source is that of municipal waste – and this comes from recycled wood or food.
Geo-Thermal Energy: Both warm water and electricity can be produced as by-products of the natural heating of the Earth by the Sun. Heating or cooling properties in the UK can be achieved using the ground source heat temperature of around 12 degrees centigrade. With four units replaced for every one unit of energy used, these heat pumps are very effective. Utilising the energy generated from wind turbines and solar electrical panels alongside heat source pumps, can make them alomst 100 percent renewable.
Wind Energy: As an energy source, wind energy has to be one of the oldest forms of energy creation in history. Where the local power grid demands it, energy can be diverted and sold there. 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. Overall, electricity could be generated from as low as 2p per kWh – instead of the current 2-10 p per kWh. Because of this, it is estimated that it takes between half a year to three quarters of a year to cover the installation costs.
Within the UK, Hydropower suits the energy generation model. Having said that, the art of using energy from moving water (just like wind power) is very traditional. In total, this could produce something like 2 percent of all electricity required in the UK.
Transforming the energy of moving water into another type (with the aid of a turbine) is known as a Hydropower system. It is by either water ‘drop-offs’, or Natural River runs, that turbines can work through this process. A ‘Micro-Hydro’ system creates energy through the use of dams and sluices (that are no longer a part of the national distribution system.) This smaller form of electrical output has been recently reviewed and could allocate some 200MW of capacity to the UK system. A micro-hydro system like this would be expected to cost between 200 and 3,000 pounds per kW of the energy.
‘Green Energy’ is growing – mainly due to the demands of the Western World. That said, the UK is well placed – especially in the domestic sector – to take full advantage of the items above.
Electrician and Plumbers are thought to be key in providing expertise during domestic installations. A range of grants are available to support the growth of renewable energy ideas within the European market. It is by gaining the right certificates that will provide opportunities and job security for the long term. By mixing green training with those of electrical or plumbing, you could cover both angles.
