A Guide To Green Engineer Courses

When our daily energy requirements are met by ‘Green Energy’, then we are using resources such as wind, tides or geothermal heat. When ‘Green’, they are all thought to be replenishable and natural. When considering elements such as Wind Power and Windmills, in many cases we are looking back at the history of energy production. This idea is preserved by the use of technology, eco-efficient options and planet friendly alternatives.

The range of renewable energy technologies utilised within the home environment includes both Solar Thermal, and Solar Water Heating Collectors. For electricity created through roof-installed panels, you would need Photovoltaic Panels or PV’s. Then there are Stoves that burn Bio-Pellets – which make up the subject commonly known as Biomass Energy. What shouldn’t be forgotten is the heat stored in the ground from the Sun – often simply referred to as Ground Source Heat Pumps. 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 Energy Systems: Often called Solar Energy, this is fact based on two types of solar panels each using different ideas to get their results. To begin with, we have the concept of drawing energy from the Sun to heat water – known as Solar Water Heating Collectors. Additionally, there is the method of converting solar radiation into electricity known as Photovoltaic – or simply Solar Electrical panels. Solar Panels themselves need to be away from all light blocks, and should be on south facing roofs at angles of 30 degrees from the horizontal plane.

As a result, Solar Water Power is often considered the most common form of Solar Energy in the UK. 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 Technology: Historically, this has come from plants and animals, though nowadays this also includes new genetcially engineered ‘energy crops’. 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. Considering all this, and the relative lack of C02 produced, makes the whole process highly green overall. 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.)

To meet the need, fast growing trees, known as Short Rotation Coppice (SRC) are utilised. 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. Agricultural Waste is commonly formed as a by-product of traditional agricultural work. However, waste derived from food or wood is another biomass entity – called Municipal Waste.

Geo-Thermal Energy Based Systems – Basically this is the warming of the Earth from the Sun – and is often used in the manufacture of warm water and electricity. By using the ground source temperature of approximately 12 degrees, we can either heat or cool buildings within the UK. Heat pumps are recognised as a very good form of power generation, generally giving back four units of energy for every one used. The energy generated by a heat source pump can in fact be considered 100 percent renewable, if the power to operate the pump comes from solar electrical panels or a wind turbine.

Wind Energy – An Update On Old Technology: 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. The UK is considered as one of the best sources of wind generation within Europe. For the fact remains that, within the UK, we have the ability to generate 10 percent of our requirement from Wind Production – as opposed to the current value of only 1 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. 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 utilising the energy from water. Interestingly enough, this type of energy production meets around 2 percent of the UK electrical total demand.

A hydropower system transforms the kinetic energy of the moving water into another type of energy by means of a turbine. By using a dam or a natural river drop, these turbines do not require water storage. 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. 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 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.

With the bulk of development work in the domestic area, both Plumbers and Electricians are set to capitalise in this area. 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. To cover both ends, you could consider electrical or plumbing training along with green systems.
