We have a serious challenge in the UK which must be addressed and acted upon in the next few years in the interests of us all - what forms of energy will power our country, our homes and our businesses in the near future?
This matters because in the next 10 years, nearly 25% of our current power stations will close as they come to the end of their lifecycle. What we invest in to power our future is a decision which matters, not only for the sake of the environment, but also for the jobs and the industries which will be created, from engineering to industrial design and manufacturing. Put simply, we can keep the lights on and create a lasting home-grown industry, or we can go for a fix of foreign energy.
The UK is not alone in having to face these important decisions. Germany, Spain, Denmark and the global powers of the US and China are also facing the challenge of needing to replace ageing power stations. The tsunami suffered by Japan last year has led that country to reconsider how to meet its energy needs.
It is a real concern therefore that certain sections of the media, urged on by think tanks keen to make headlines, are striving to make this a debate based on their own pseudo-science, rather than the crucial facts. In doing so, they risk damaging a growing industry which is creating thousands of engineering jobs and a export manufacturing industry for the UK of which we can all be proud.
In Germany, nearly 10% of electricity is produced by wind power. The country's engineering sector has created a major turbine export industry which supplies the world. With nearly 30,000 wind turbines located mainly onshore, the German government has produced a policy which will seek 100% reliance on renewable energy for electricity production by 2050. This undertaking will include a further expansion of wind farms, particularly offshore.
When Chancellor Merkel announced last year her administration would phase out its ageing nuclear power stations and not replace them, it was considered to be a response to the Fukushima disaster in Japan. This may have played a part in that decision, but it was also taken because her country had invested in a successful alternative, boosting German industry, and ending much of its dependence on other sources of power.
So why then has the think tank Civitas claimed that "there is no economic case for wind power"? They argued that back-up costs from non-renewable energy sources at times when the wind doesn't blow means that wind would be more expensive; they stated this back-up might contribute to carbon emissions; they also said the National Grid would need to be developed to take power from wind farms to where people live, adding to costs.
This alleged need for extensive and expensive back-up is an argument that has not held back Germany, Spain or the USA. That is because in their far more mature wind energy industry, it has been proved not to be a significant challenge at all. Wind has, because of its very reliability, been a major contributor to reducing carbon emissions. As for the need to develop the grid, this is required for most new power sources as they are not near the facilities they replace. So as we renew a substantial percentage of our power generation in the next ten years, this will be a major consideration for any new power stations, whether they are wind farms or not.
Ruth Lea, the author of the Civitas report, does concede that "a mix of technologies is preferable for operational reasons". I could not agree more. But then she lowered the tone by describing wind energy as an "expensive folly".
The only folly I can see is that of ignoring the development of the wind energy industry in other countries where so many of our peers see their path to secure, safe, clean energy production to be anchored by wind.
So, as we engage in this crucial debate in the coming months we must base these vital decisions on what has been proved to work in other countries - not pseudo-science - and what is already creating lasting and affordable energy solutions and a home-grown engineering industry here in the UK. This is not just for the benefit of future generations, it's for the sake of common sense.

Renewable-energy misery spreads to Vestas, as the Danish wind turbine maker ...
Worldwide Renewable Energy Investments Rose to Record $260 Billion in 2011
Numerous studies have shown this statement to be a canard. As wind even over a wide area grid, requires constant backup at 100% nameplate capacity from low efficiency gas plant run inefficiently. Less gas less GHG's, less money replacing that deadly combo with high efficiency gas plant.
Gas is no answer - it's a finite resource. Our fuel prices will go ever upwards.
You're presumably set in a US mindset with a local grid model. The UK has a national grid. If you want efficiency and quick response you can also in principle get that from expensive, but small Rolls-Royce-WR21-type recuperated turbines.
For long calm spells you still have to buy the costly gas plant at at 100% wind's name plate capacity. The WR21's are extremely inefficient.
"Why Nuclear?” If you look at the chart at the top right of the slide below, SCANA provided their all-in cost estimates for nuclear ($76/MWh), natural gas ($81/MWh), coal ($117/MWh), offshore wind
($292/MWh) and solar ($437/MWh). For them, “new nuclear continues to be the low cost alternativ"

Here's Stephen Byrne, executive vice president of South Carolina Electricity and Gas, explaining why a utility executive would opt to build a new nuclear power plant.
“We choose nuclear over other energy alternatives for four main reasons. First, the need for baseload power. The new units will help meet state regulatory reserve margin requirements. Second, cost. Nuclear is competitive with other baseload options when evaluated over its 40-year design life. Third is fuel diversity, adding units 2 and 3 [at V.C. Summer] will increase the share of nuclear in our fuel portfolio from approximately 11 percent to approximately 30 percent…Fourth is its low greenhouse gas emissions.”
In the artificial game he's being allowed to play, it makes sense.
On the other hand, it would be impossible to build wind/solar plant if the families of the thousands of citizens murdered every year by deadly fine particulate air polluting radioactive gas spewing fracked natural gas plant required to backup wind/solar at 100% nameplate, could sue.
Given that a single terrorist with a shoulder fired missile could wipe out many American cities in a nuclear bomb sized LNG storage or tanker explosion, while the zero death meltdown risk in a modern nuke reactor is now certified by the NRC at 1 such accident in every 5 million years of plant operation, I'd say he was making a same bet.
All the proposals for alternatives , without exception, suggest ways of producing electricity. Whereas our entire civilisation functions on fossil fuels for more than just power alone. literally everything has embedded within it a quantity of energy derived from coal oil or gas, Your home and everything in it could not exist without it, your job would vanish, as would our transport system and your entire food supply. we have built our world on hydrocarbons, yet we are offered the nonsense of 'infinite electricity' as if that will somehow allow mankind to continue 'business as usual'
The output from 1000 windfarms won't produce an inch of (hydrocarbon) insulation on electric wiring or an ounce of artificial fertiliser. Remove insulation from wiring and we're bombed back into a medieval society, when we can no longer make artificial fertiliser we'll be killing each other for food.
There really are no alternatives folks, so take windfarms and solar panels off your wishlists

That's why we are still yet without Nuclear Fusion, when it is so close. But inherited a mass amount of global conflict and world debt over a war which about a fuel which could be made obsolute. The current cost of the Iraq and Afgan war could have improved the current nuclear fussion programs across the world and we could alll be a step closer to cleaner, more efficient power resources.
The question we all need to be asking is WHY? Because the oil tycoons and governments and more importantly WORLD ELITE, make to much money out of the current fuels and technology. In short we all need to wake up and smell the cheese. Before alot of nations find there selves with complete generations of people feeling angry, suppressed, dictated to, HELLO. It's already happening.

Magnetism can produce free energy in this way because it already has the energy. For example if I tied a metal ring to a piece of string and then dangled it over a magnet, the magnet would have the energy to spin the metal ring around. There is a transfer for energy from the magnet and the metal. Both transfer to spin the ring around and around it will never stop spinning as long as it is within distance of the magnet.

here is a couple of links .
Also there are more efficient ways of producing energy than fossil fuels, Nuclear Fusion should have far more funding and is something which we should be able to achieve. I am sure the wars in Iraq and Afghanistan cost alot 100 of billions a year. This money could have already us a fusion using civilization.
Wind always looks reasonably good in windy places. The problem for the UK is that the windiest places are a long way - about 400 miles - from significant demand, and sufficient grid connections are not in place across the sensitive intervening landscape. New pumped storage hydro is probably necessary in Scotland alongside this development, which makes it expensive.
Shale gas in the UK could now change the local natural gas market landscape too, since there is no LNG import or export capability.
If your machine can generate 5MW, you need to be careful lest it try to make 10MW. The fraction of the time that wind turbines have to close down for too high windspeeds is small.
This debate needs to get its head out of the clouds with regards to renewable energy. That is because we need a facility in the national grid to support the base load and also have the ability to respond quickly to fluctuating demands, tea breaks during corrie, football matches etc. Wind alone will cannot support these functions especially in periods of calm weather, anyone remember the winter of 2009/2010 the weather system was practically stationary which resulted in the severe cold temperatures and little or no wind for days. Gas, oil, coal, or pumped storage(reservoirs dropping water down pipes) or nuclear power can and do meet these demands. Electricity for the grid currently is near impossible to store so it has to be a variable load driven network, The strategic solution needs to have a mix of fuel types and not just pandering to the green voice. Apart from that its really easy.
So there are rapid developments in energy storage, which you quite rightly point out has been the main problem for wider use.
Yes, we need to investigate all pollution-free forms of energy generation, and all the 'green voice' wishes is that green energy receives, and continues to receive, a reasonable initial subsidy, unlike nuclear has received an ongoing subsidy for many decades.
You are also correct in saying that wind is not the answer, but it's part of the solution we all seek in our individual ways to achieve energy security.
An interesting thought that also has been posited by some is that the planet as a whole is a power system, i.e the wind, weather, tides etc are all caused by the thermal solar & cosmic energy imparted upon the planets surface. Now if we take excess energy out & convert it into pv, wind to electricity, tide to electricity are we not taking out the energy required to drive our weather systems? What problems could that cause?
For those who are comparing wind & other renewables with 'conventional' or nuclear, you're comparing apples with pears.
Wind, even to the most convinced renewable power advocates, was never seen as a replacement for current generation sources.
Wind is only a part of a raft of renewable sources to eventually replace fossil-fuelled power sources and nuclear.
Nuclear is expensive & potentially, catastrophically dangerous. Every watt of nuclear energy since the first station opened in 1956 is subsidised in our quarterly bills - to this day.
In the long-term, Britain must face the inconvenient facts - fossil fuels are getting more scarce, and in a market-driven environment, that means it gets increasingly more expensive.
We need a mature, balanced debate on our energy future, incorporating as many renewables as possible, backed up - in the short-term - by 'conventional' power sources, which can be gradually phased out as newer, less polluting forms of energy are developed.
If we continue as we are, we will hit the proverbial brick wall, and no sensible person should avoid seeking a solution for this and future generations.
There are things we can do right now, and others that will take more time, but wind - in the best wind source area in Europe - must remain as part of our energy future.
The potential sites will cause local anguish, but that's another argument for another day.
Georgia power is soaking ratepayers for new nuke that may or may not be built. Cost overruns are punishing ratepayers.

The safe disposal of nuclear waste has been the unsolved 'problem' since day one, and the best we have come up with so far is 'safe and secure storage awaiting a disposal solution' to quote the Authorities.
Whilst safe and secure storage is essential, it is also energy-intensive and a security nightmare for as long as it's lethal - many hundreds of thousands of years.
Long ago, it was calculated that no nuclear plant ever built has ever 'paid back' the energy to construct, maintain, run throughout its lifetime, decommissioning and the old thorny problem of 'safe disposal of nuclear waste'.
If you've come up with a solution as briefly described in your post, I'd be inclined to have it peer-reviewed and, if successful, be ready with a fleet of trucks to carry away all the money.
.... but don't hold your breath.
All the worlds nuclear waste now perfectly contained would fill 1% the volume of the Great Pyramid at Giza which has lasted 5000 years - less than a football field buried 40 feet deep. Not waste. It is fuel enough to power the world for hundreds of years while being destroyed in gen IV reactors like India's new 500 MW first of 5 units. Ironically that is the only way to get rid of it.
