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’. It is easy to think that we may be travelling back in time when we think of items such as wind power and windmills. Generally, this is the result of using up to date ideas, specifically those that are planet friendly and eco-efficient.

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.

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.

Systems Utilising Biomass Energy: This term encompasses all forms of natural products – such as plant and animal material. It is extremely useful – in that it can produce a range of power sources, including heat and electricity. 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. One of the main factors of this style of energy is the result without the impact on C02. With a new tree being planted as each is felled, you can see how the C02 produced during heating is minimised – and why the system is deemed sustainable.

By the growth of Short Rotation Crops (SRC), the UK is able to maximise the ‘Energy Crops’ return overall. Perennial grasses are also responsible for large quantities of dry matter. Municipal and Agricultural waste products are both little known, but essential materials to this field. Under normal agricultural activity, agricultural waste is a natural by-product. Whereas Municipal Waste is derived from wood or food – and can be used for biomass energy.

Systems Using Geo-Thermal Energy – The constant energy of the Sun heating the Earth results in both warm water and electricity being produced. Within the UK, the constant ground source heat temperature is around 12 degrees centigrade – and can be utilised to both heat and cool buildings. Generally, items such as Heat Pumps are thought of as very effective, as they produce four units of energy for every one that is used for generation. 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.

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.

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.

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.
