Uncovering Environmental Training Courses – StraightForward Advice
It is the use of tides or wind to deliver our daily energy needs that form ’Green Energy’. ’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 eco-effiency and planet friendly options.
Solar Thermal and Solar Water Heating Collectors are examples of what can be used in your house as part of renewable energy technologies. Equally there is electricity that is generated through roof-installed panels. Following on from this is a process known as Biomass Energy – which includes Boilers burning wood and other fuels. There is also the ground heat from the Sun – now known as Ground Source Heat Pumps. Considering items such as Wind Power and Hydro Turbines, we are finally getting to very old forms of energy production.
Solar Energy Systems: Typically referred to as Solar Energy this is mainly made up of two types of Solar Panels – each using different methods to achieve similar results. As a first strategy, we have Solar Water Heating Collectors – which basically creates hot water from solar energy. Added to this is the generation of electricity from solar radiation – known as Photovoltaism, or more commonly Solar Electrical panels. Obviously situated away from blockages such as chimneys etc., these Solar Panels need to be mounted on south facing roofs at an angle of 30 degrees from the horizontal.
As a result, Solar Water Power is often considered the most common form of Solar Energy in the UK. With the ability to provide almost half the annual need for hot water in the house, Solar Water heating systems are very important. 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: This is a ’capture all’ phrase which includes all natural materials. e.g. Wood, straw and poultry litter – but nowadays also includes modern ’Energy Crops’. It is by using these materials in new ways to create energy that makes it so exciting. Furthermore, within the European Markets, the UK is one of the central producers of Biomass fuels. One of the main factors of this style of energy is the result without the impact on C02. 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.)
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 ability to produce dry matter – and perennial grasses are very good for this. Of equal importance, although maybe less well known, are Municipal and Agricultural Waste. As a by-product, Agricultural Waste is simply part of the farming process. Of equal importance is Municipal Waste, which comes from recycyled wood and food.
Geo-Thermal Energy Based Systems – By naturally heating the Earth, the Sun has the potential to generate both warm water and electricity. Within the UK, the constant ground source heat temperature is around 12 degrees centigrade – and can be utilised to both heat and cool buildings. Heat pumps are recognised as a very good form of power generation, generally giving back four units of energy for every one used. By using energy from solar electrical panels or wind turbines to power them, heat source pumps can be almost 100 percent renewable in energy production.
Wind Energy – An Update On Old Technology: The use of wind as a source of energy has been going on for thousands of years, especially in milling grain and pumping water. More recently, there has been the desire to deliver the energy created to the home – or to a local power grid. With regard to wind generation, it is the UK that has the highest production within Europe. Although we only utilise 1 percent of the current electricity capability from wind – we do have the ability to create 10 percent. Frankly, electricity can be realised from as little as 2p per kWh – as opposed to the current level of 2-10 p per kWh. The financial recovery process takes around 6-9 months.
Last of all there is Hydropower – an area of especial importance to the UK. The ability to utilise energy from moving water, much like wind power, has been going on for thousands of years. That said, this type of energy can generate around 2 percent of the total electrical demand for the UK.
Using a turbine, a Hydropower system can transform the energy of water into other forms. It is by either water ’drop-offs’, or Natural River runs, that turbines can work through this process. ’Micro-Hydro’ utilises a chunk of the outdated sluices and dam systems that have been killed off by the large national distribution methods. This smaller form of electrical output has been recently reviewed and could allocate some 200MW of capacity to the UK system. The capital cost of installing a micro-hydro system can run between 200 and 3000 pounds per kW of energy output.
The demand on ’Green Energy’ continues to develop – in light of the energy demands worldwide. The UK remains one of the main beneficiaries of this technology.
Electricians and Plumbers in particular are expected to provide the main thrust of domestic installation expertise. 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. Gaining installation certification across these areas can only provide further opportunity and job security to anyone already in related fields or looking to retrain. By mixing green training with those of electrical or plumbing, you could cover both angles.
