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 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.

With Solar Power being so common within the UK, it's Solar Water Power that is most often used. With the capacity to deliver 50 percent plus of a household's hot water requirement annually, Solar Water heating systems are crucial to energy in the UK. There are two options to fit these items. The first is to get a professional fit and the second is a DIY system, the first will cost around 2-5k and the second between 500 and 1500 pounds.

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.)

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). Also producing high yields of dry matter are the perennial grasses. Other less known materials within this field are Agricultural and Municipal Waste. One natural offshoot of agricultural work is Agricultural Waste. Because it comes from food or wood, Municipal Waste is also considered a useful biomass product.

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 Systems: Wind Energy as a sustainable source of energy has been going on for millennia. 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. The ability to utilise wind generation is considered to be greatest in the UK. 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. Electricity can be produced from as little as 2p per kWh, but generally comes in somewhere between 2-10p per kWh. Recovery of the cost involved is somewhere between 6-9 months.

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 is the growing worldwide energy requirement that is causing the growth in 'Green Energy'. The UK remains one of the main beneficiaries of this technology.

Once again, it is the Electrician and Plumbing trades that are set to capitalise on the domestic installation process. Grants and financial aid is also set to increase within the EEC and the UK - as 'Green Energy' gets ever higher status. This is a new industry - but getting the right certification can only improve job security and opportunities for the future. Look for combined electrical and plumbing training, with a key emphasis on practical green systems and installation.
