Basically, the ‘Green Energy’ idea is how our everyday needs are supplied by natural resources such as wind, tides and even geothermal heat. Collectively they are thought to be ‘Green’ because they are ecologically sound and easy to replace. The older energy skill sets have had value for years, especially when we think of wind power and windmills. However, it is the result of eco-efficient and planet friendly options that this process is maintained.
It is the use of simple renewable energies such as Solar Thermal and Solar Water Heating Collectors, that suits the home environment. 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 revolves around stoves and boilers – which are known as Biomass Energy. Then there are the Ground Source Heat Pumps, which is simply the ground heat created by the Sun. At the end there are two of the most mature forms of energy production in the UK – albeit renamed now to Wind Turbines and Hydropower.
Solar Thermal Energy – By using different technologies, Solar Energy is effectively made up of two types of solar panels. Initially, there is the process of obtaining hot water from the Sun via Solar Water Heating Collectors. Additionally, there is the method of converting solar radiation into electricity known as Photovoltaic – or simply 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.
With Solar Power being so common within the UK, it’s Solar Water Power that is most often used. Solar Water heating systems can meet the need for more than half of all hot water needs in the domestic market. The average cost of installing this type of equipment is expected to range from 500 to 1500 pounds for a DIY system, through to 2-5k for a professionally installed system.
Biomass Energy Systems – Including all natural energy forms derived from plant and animal products – such as 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 green strengths – as it has one of the larger Biomass legacies within Europe. It should be borne in mind that the whole process is designed to produce energy without an impact on CO2. Having a tree planted in place of another (that is felled for energy production) helps overall.
To meet the need, fast growing trees, known as Short Rotation Coppice (SRC) are utilised. Perennial grasses are also responsible for large quantities of dry matter. Within this process also sits the lesser known Agricultural and Municipal Wastes. To begin with, Agricultural Waste is often produced as part of the agricultural process overall. However, waste derived from food or wood is another biomass entity – called Municipal Waste.
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.
Systems Based On Wind Energy: As an energy source, wind energy has to be one of the oldest forms of energy creation in history. However, in more recent times there’s been the option to recover the energy for its own sake – and deliver this either to a home unit or to the local power grid. To be fair, the UK has the highest level of wind generation within Europe. Although, within the UK we currently only utilise 1 percent of electricity from wind, yet the potential rests at a surprising 10 percent. Rather than electricity production running at 2-10 p per kWh, it could be run at 2p per kWh. Recovery of the cost involved is somewhere between 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.
Because of the energy need of the Western World, we are now seeing a rapid rise in ‘Green Energy’. The UK domestic market appears to be one of the core 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.
