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.

In a bid to reduce Britain’s dependency on fossil fuels such as coal, gas and oil the government has introduced its Renewable Energy Strategy.
Heavily weighed down by its promise to reduce CO2 emissions by 34% by 2020 and 80% by 2050, the government is poised to invest £100 billion into a renewable energy infrastructure, including 7,000 wind turbines by 2020.
All well and good, but the increased cost to the consumer could result in many households facing fuel poverty. It is anticipated that bills will have to rise by 20% to pay for this investment. The average household currently pays approximately £1,150 a year for electricity and gas, the cost of converting to renewable energy and modernising Britain’s power stations could add another £230 to this.
Too bitter a pill to swallow? Then be aware that in all likelihood, as things stand our energy prices will increase anyway, so it’s crucial to make a positive change before it’s too late.
