A Guide To Green Engineer Courses

It is by using natural resources such as tidal or wind energy – collectively known as \’Green Energy\’ – that we could meet our daily energy needs. They are considered \’Green\’ because they are environmentally friendly. The older energy skill sets have had value for years, especially when we think of wind power and windmills. Regardless of this, we are mainly talking about using modern techniques to offer planet friendly and eco-efficient solutions.

The home can use a range of new ideas to help with energy usage – including Solar Thermal and Solar Water Heating Collectors. To gain electricity from roof panels you would need solar electrical panels (PV\’s). Another key element is that of Biomass Energy, which relates to Stoves and Boilers burning Wood, Fuel and Pellets. Of course, then there is the heating from the Sun – often just called Ground Source Heat Pumps. Finally, we have two of the most traditional forms of energy generation that have gone through some resurgence over the last few years; these being Wind Power, Wind Turbines and Hydropower (including Water Wheels.)

Solar Thermal Energy – By using different technologies, Solar Energy is effectively made up of two types of solar panels. 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. 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.

Within Solar Energy overall, Solar Water Power is most commonly used in the UK. Solar Water heating systems are extremely important – and can provide over half of the hot water needs for houses within the UK. The typical cost for installation ranges from 500-1500 pounds for a DIY system, all the way through to 2-5k for a professional fit.

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 Technology: Used in the generation of both warm water and electricity, this energy mainly comes from the Sun and heats the Earth. Using the ground temperature of around 12 degrees in the UK – we can both heat and cool buildings. Although heat pumps require energy to function, their rate of return is superb – being a four-fold benefit over the energy put in. Heat source pump energy can go one step further (by gaining a 100 percent return) if the energy to power them comes from items such as wind turbines or solar electrical panels.

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.

By using a turbine, a Hydropower system can transfer the kinetic energy of moving water into another form. Turbines use either a water drop (e.g. through a dam) or by a natural \’run of the river\’ – thereby having no water storage reservoir. \’Micro-Hydro\’ however utilises old outdated sluices and dams. Whilst considered a smaller form of electrical output, this system is thought to be able to give some 200mW of capacity to the UK. When considering the installation cost of items such as this, we\’re looking at somewhere between 200 pounds and 3k per kW of energy created.

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. The UK domestic market appears to be one of the core beneficiaries of this technology.

It is the drive for installations in the domestic sector that looks to favour jobs such as plumbers and electricians. It is the political view of this type of energy generation that results in grants and financial aid becoming ever-more prevalent. It is important to gain the correct qualifications to install these items. You could consider either plumbing or electrical training programs that highlight green installation.
