There has been a lot of press recently concerning the UK wind farms and the need for more wind turbines in the aim to tackle global warming and to increase the use of green energy.
Harnessing the winds power can and does ganerate a huge amount of useable energy. However, it has now been reported that there could be an overload of energy onto the National Grid if it gets too windy.
Too windy? Surely, this would be a good condition considering how unstable and infrequent the weather can be. To store up lots of wind-generate electricity cant harm us can it? Apparently, according to those at the National grid, too much wind and too much wind-generated electricity is not a good thing.
Owners of wind farms are now going to be awarded a payment to switch off thier turbines if it does become ‘too windy’. This seems all well and good in the grand scheme of helping the country to use more sustainable energy sources but this payment to the wind farm owners is going to come from the tax payers.
The National Grid is constantly working to match the need for electricity with supply and this can often be determined by weather predictions and TV schedules. Plant failures and erratic weather changes are also a factor when the National Grid juggles electricity use across the nation. They feel that the balance between using the wind famrs and deciding to turn them off in adverse weather conditions will prevent the network from being overloaded.

It has been released in a new report that China have pushed their way to the top of the leader board for renewable energy, replacing the U. S as the number country investing the most towards renewable technology. Moving into the top spot, China is being named as a new clean tech superpower.
For the first time the United States have been replaced at the top spot and have moved down the table below the UK, Germany and France. The new report put together by the non-profit organisation The Pew Charitable Trusts was published recently and is a detailed league table of investments in low-carbon energy among the G-20.
The table, cataloging 2009 clean energy data, shows China investing almost twice as much as the U. S. However, the U. S are still leading the way in energy capacity, and dont rule out the UK! We, as a nation are right up there on podium, showing that we can contribute with the larger countries to really make a difference. The UK are 3rd in the overall results for clean energy investments, 4th in the 5 year clean energy investment growth rate and 5th in the percentage of total power it receives from clean energy sources ahead of France, China and the United States.
This report shows that not only the big guns are really trying to put something back and help towards finding some new and renewable solutions.

- Tidal Turbine
This month saw David Kidney MP, Under secretary for energy and climate change speak at the Renewable UK Conference in Westminster. The topic of the talk was on the growing productivity of wave and tidal energy in the UK. He commented “Harnessing electricity from our wave and tidal resources not only plays a crucial part in meeting our climate change target; but also presents a significant economic opportunity for the UK.”
Wind power is now the top renewable source, due to the expansion of offshore wind farms and this is an encouraging move towards harnessing weather elements. David Kidney has pledged to support the wave and tidal power projects and it is now said that the UK are seen as the leaders in marine energy technology.
In April 2008, the world’s first commercial tidal current power system with a capacity of 1.2MW was put into action in Strangford Lough, Northern Ireland. With the tide flowing at over 7.4 knots it was an ideal location to place this world’s first.
The SeaGen tidal turbine was installed by MCT (Marine Current Turbines Ltd) and is the largest grid-connected marine renewable system in the world. Similar to the wind turbines it is a modular technology and works on generating low carbon energy.
Strangford Lough’s turbine has recently reached the milestone marker of 1000 operational hours, being the first and only tidal turbine to have done so. This world’s largest ever tidal current device generates clean and sustainable electricity for 1000 homes and has so far delivered over 800MW into the Northern Ireland grid. With expectations being exceeded for this system it is leading the way in technology of this type and will shape the future of tidal current power. Martin Wright MCT’s MD reflected “We will build on the success ofSeaGen to develop a commercial tidal farm of up to 10MW in UK waters within three years.”
After recently being granted the lease, MCT are going to deploy the award-winning SeaGenturbines off Brough Ness, on the southernmost tip of the Orkney Islands and north east of John O’Groats. By 2017, 66 SeaGen tidal turbines are going to be placed in three phases with a total generating capacity of 99MW. That’s enough power for almost 100,000 homes.

Surely the announcement of a £1billion investment in wind farm off the coast of Dorset is a matter of civic pride and not a threat. That’s the hope which Guy Madgwick, Director of Business at Eneco, the company hoping to undertake the project, expressed in the Bournemouth Echo.
Not only could the construction create up to 2,300 jobs, but the site itself could generate power for approximately 587,000 homes.
The area being considered for the new wind farm is roughly 25km out to sea and stretches from south of the Needles on the Isle of Wight to the Purbecks. It will only be visible in the distance on clear days so could not be considered an eyesore.
The UK is apparently the windiest country in Europe and with wind generated power currently the most developed and effective of alternative energy sources, the project seems to present an exciting win-win situation.

The University of Bath is undergoing a project to find environmentally friendly building materials that can be used as an alternative to the current products used within the construction industry.
A straw house came up as a viable option. Straw is not only a renewable resource, but also a farming by-product, which made it a popular choice for the researchers. It can be locally grown and absorbs carbon monoxide, therefore buildings made from straw have zero or even a negative carbon footprint. It can potentially provide such good insulation that normal heating may not be necessary, keeping running costs low and minimising environmental impact.
The construction itself has been built using prefabricated panels, consisting of wooden frames filled with straw or hemp, then rendered with a breathable lime based system.
Research into alternative building materials is important as cement contributes up to 10% of all carbon dioxide emissions. Hopefully this project, which over the year is to be monitored, will prove that straw is a sustainable building material. Let’s just hope it can withstand all the wolves huffing and puffing and trying to blow the house down!

Climate change activists, such as: Camp for Climate Action, Plane Stupid, Climate Rush, Rising Tide and others have joined forces and as the result of an on-line public vote, have organised a mega pubic get together to close one of the UK’s biggest coal fired power stations: E.ON’s Ratcliffe-on-Soar in Nottingham
In the run up to Copenhagen, there is a mounting feeling of tension, which is spilling over into impressive calls for action. Growing numbers of people are feeling that it’s time to take action into their own hands as they become increasingly frustrated not to mention embarrassed by the extreme level of foot dragging going on in the UK over climate change – namely by the government and leading corporations.
The Great Climate Swoop openly recognizes the vital role coal has played in our nation’s past, however now it is time to take responsibility for our future. Burning coal is now the biggest single source of carbon emissions in the UK.
Although Drax is Europe’s biggest coal power station, and the UK’s largest source of carbon emissions, with a nod to the reality TV voting systems, the power station selected by thousands of interested parties for ‘Direct Action’ is Ratcliffe-on-Soar – the UK’s 3rd largest source of carbon emissions, with plans to build a controversial new coal plant at Kingsnorth.
The ‘Great Climate Swoop’ is planned for 17th and 18th October and will operate on the same basis as the G20 camp, which was deemed massively successful due to the fact that the protestors managed to set up camp completely avoiding police surveillance!

Vestas is considered to be number 1 in modern energy, with 20% of market share and more than 38,000 wind turbines worldwide. So why did our government allow the closure of Vestas in the Isle of Wight, our only UK turbine manufacturer? What happened to their ‘green promise’ that supported the installation of 10,000 wind turbines in the UK by 2020?
To add insult to injury the government managed to find £340m to bail out Airbus, the company who likes to promote itself as an ‘environmentally benign organisation’. Currently Airbus are advertising their plan to cut fuel emissions by 2%.
2% in a rapidly growing industry, about to be responsible for potentially catastrophic fuel emissions is of what use exactly? In addition to this and very interestingly, Airbus’s Chief Executive claimed a government bail-out was not necessary and what was actually required was a ‘functioning financial system’ to be set in place.
