What Green Engineer Courses Should I Consider
In a nutshell, 'Green Energy' utilises natural resources such as sunlight, wind, tides and geothermal heat to provide our daily energy requirement. They're all considered naturally able to replenish and thereby 'Green'. The older energy skill sets often have value set in times gone by especially when we think of wind power and windmills. This option is preserved by the use of technology, eco-efficient options and planet friendly alternatives.
The home can use a range of new ideas to help with energy usage including Solar Thermal and Solar Water Heating Collectors. Equally there is the basic electricity generated through roof-installed panels. Equally important is that of Biomass Energy which includes Stoves, Fuel, Pellets and Boilers burning Wood. Then we have the ancient energy of the Sun and the heat that come it - now often called Ground Source Heat Pumps. At the end there are two of the most mature forms of energy methods in the UK albeit renamed as Wind Turbines and Hydropower.
For those wanting to train in this area we will expand on each section and cover off some of the skills required. Thinking about the issues already, this is definitely of interest to those in the field namely Plumbers, Electricians and Gas engineers. Checking out the pages on Electricity, Green and Plumbing careers would also help gather as much information as possible. CTRL-D this site now so that you can come back later and look at the links and adverts of relative training providers.
Thermal Energy Systems: Often called Solar Energy, this is fact based on two types of solar panels each using different ideas to get their 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.
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.
Systems Utilising Biomass Energy: Although in the modern world this now includes 'Energy Crops' it also takes in suitable plant and animal substances. Due to its adaptability it can produce a range of energy forms from heat and electricity through to combinations of both. It is interesting to note that the UK has some of the largest quantities of Biomass material to generate electricity within Europe. One of the main factors of this style of energy is the result without the impact on C02. With each tree being planted as another is felled you can see how the C02 produced during heating is minimised and why the system is deemed sustainable.
'Energy Crops' such as Willow and Poplar play a major part in the process under the banner of Short Rotation Coppice (SRC). Of equal importance is the ability to produce dry matter and perennial grasses are very good for this. Equally significant within this practise sit Municipal and Agricultural waste products. To begin with Agricultural Waste is often produced as part of the agricultural process overall. Whereas Municipal Waste is derived from wood or food and can be used for biomass energy.
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.
Wind Energy Based Systems - The use of wind as a source of energy has been going on for thousands of years, especially in milling grain and pumping water. That aside the ability to generate energy and transfer this onto homes or the local grid has been a relatively new option. In fact, the UK has the largest wind resource within Europe. Potentially we can produce 10 percent of our annual energy needs through wind power although at present within the UK we still only use 1 percent. Although electricity is still being produced from between 2-10 p per kWh it could be generated from as little as 2p per kWh. Due to this we are looking at 6-9 months in total to cover the costs.
Finally, we have Hydropower; an area in which the UK does well within Europe. Just like a thousand years ago we are looking utilising energy from water. That aside it is fair to say that some 2 percent of the UK's electrical load comes from this source.
A hydropower system transforms the kinetic energy of the moving water into another type of energy by means of a turbine. The important thing is that without relying on water storage the turbines can generate electricity. 'Micro-Hydro' utilises a chunk of the outdated sluices and dam systems that have been killed off by the large national distribution methods. Whilst considered a small form of electrical output this system has been thought to be able to give some 200mW of capacity to the UK. The capital cost of installing a micro-hydro system can run between 200 and 3000 pounds per kW of energy output.
It can be seen that the route to 'Green Energy' is growing considerably, especially in light of the need for increasing energy outputs throughout the Western World. To be fair, the UK domestic market is leading the resurgence with the variety of schemes detailed above.
With the rise in demand for domestic installations both Electricians and Plumbers are well placed to take advantage of this technology. Not only in the EEC but also in the UK 'Green Energy' is rapidly gaining ground as the way forward and a range of financial incentives are in place to support this. It is by gaining the right certificates across the board that will help opportunities and job security for the long term. To that end it may be worth thinking about combined training where you can get plumbing or electrical training along with green knowledge.
