Is the future of wind energy as high as a kite?

Wind energy is often criticised for being unreliable. However, there is almost always wind blowing in the UK - it's just a little higher up than we currently reach. High above the friction with the ground, high altitude winds are stronger and much more stable than those close to gro…

Equal feed-in tariff for existing generation has heavyweight support

Support for equal feed-in rates for those who already have small solar PV, wind turbines or hydro came from diverse parts of the renewable energy sector at yesterday's RegenSW conference in Bristol. Sponsor Christine Griffiths of Aeolus Power got her passionate call in early in the day - to be me…

Island grid increases energy security aspect of microgeneration

Island grid increases energy security aspect of microgeneration

Security of electricity supply is one of the main reasons that people install their own solar panels or wind turbine. However, a system that is connected to the national grid currently doesn't afford total control. The benefit of grid connection is that you can sell any excess you generate to the…

Existing generators angry at feed-in cuts to income

Posted by Cathy Debenham on 15 September 2009 at 8:32 am

Existing generators angry at feed-in cuts to income

Feed-in tariffs are designed to incentivise people to invest in renewable sources of energy generation. Yet, the government's proposals will give much lower rates to existing microgenerators, leading to a cut in income for many. This seems a perverse move from government. The numbers of micro wi…

Wind turbines: is vertical or horizontal best?

Posted by Graham Eastwick on 24 August 2009 at 12:05 pm

Wind turbines: is vertical or horizontal best?

There are two main categories of small wind turbines you will see as you travel around the UK today. Horizontal axis turbines look like traditional wind turbines and typically have two or three blades. Vertical axis turbines come in a number of designs, a spiral or some paddles blowing around in …

Off-grid versus on-grid microgeneration in practice

Off-grid versus on-grid microgeneration in practice

I really needed a holiday this year. So when we arrived at the holiday cottage we had rented in Orkney and saw the 6kW wind turbine outside my heart sank a little. We had accidentally opted for two weeks of off-grid existence – and slightly dodgily designed off-grid existence at that – with only…

Feed-in tariffs are not fair to renewable energy pioneers

Feed-in tariffs are not fair to renewable energy pioneers

Renewable energy pioneers have been dealt a dismal hand by DECC's proposed rates for the feed-in tariff. Existing microgenerators (whose installation has been accredited under the Renewable Obligation) will be automatically transferred to the feed-in tariff on a rate of 9p per kWh (kilowatt hours)…

Welsh ease planning rules for renewable energy

Welsh planning rules for domestic renewable energy installations have been changed to make it easier for homeowners to generate their own heat and electricity. Following Scotland's lead, the Welsh Assembly has announced new regulations which mean that some microgeneration technologies will no lon…

Will feed in tariffs change the market?

Posted by Matthew Rhodes on 7 August 2009 at 9:03 am

Will feed in tariffs change the market?

The announcement by the Government last month of proposed feed-in tariffs (FiTs) for renewables from next April marks a fundamental change in the way small scale renewables are incentivised in the UK, and is long overdue. There is no question that feed-in tariffs are the right mechanism to use. …

Measure the wind before you install a turbine

Posted by Cathy Debenham on 5 August 2009 at 9:08 am

Measure the wind before you install a turbine

Product and installation standards for domestic wind turbines are needed, as are improved wind speed prediction and better site assessments. These are some of the key conclusions of the Energy Saving Trust's microwind research published in July. On measuring the wind speed, EST recommends that, …

What the renewable energy strategy and low carbon transition plan mean for your home

Households are expected to make cuts in their carbon emissions of 29% by 2020 according to the Government's Low Carbon Transition Plan, announced by Ed Miliband last week (houses currently emit more than a third of the UK's carbon). This will be done through a combination of cutting the amount o…

Wind power trial results published

The results of the Energy Savings Trust wind trial were published this week. This trial monitored both the performance of building-mounted turbines and turbines mounted on free-standing poles. In line with the previously published Warwick Wind Trials the study concluded that location is the most im…

What size and type of turbine is most suitable for my site?

What size and type of turbine is most suitable for my site?

Choosing the best wind turbine for your site will depend on a number of factors. The first thing is to determine if you have enough wind. A national database of wind speeds is available and will give you an indication of the wind speed at your home. This can be accessed fr…

Wind power without the guesswork

Wind power without the guesswork

Measuring wind power to see whether it makes sense to get a wind turbine has, until now, been either expensive or inaccurate. Now with the launch of the Power Predictor, it’s possible to take the risk out of what is a significant investment. The device is the invention of Toby Hammond, managing…

Selling the electricity you generate

If you think that choosing your utility supplier is complex and painful, then just wait until you start exploring the tariffs for exporting the electricity you generate back to the grid.  There are two main ways of selling your electricity. Some suppliers pay for all the electricity you gen…

Support for microgenerators increased this month

Financial incentives for people generating electricity with photovoltaic solar panels (PV) are provided though the system of renewable obligations certificates, (commonly referred to as ROCs). All electricity providers have to buy these certificates each year, in proportion to the amount o…

Maldives to be powered by wind and solar

The President of the Maldives has set an example for the world by announcing that his country will be carbon-neutral within a decade. Half a square kilometre of rooftop solar panels, 155 large wind turbines and a biomass plant burning coconut husks will generate the electricity the island country ne…

Who makes wind turbines in the UK?

Who makes wind turbines in the UK?

One of the nicer things about the wind industry, especially the small wind industry, is that there are still only a relatively small number of manufacturers and distributors in the UK, so you can get a good feel for the market quite quickly. In the sub 10kW range, the most successful companies a…

Urban micro-wind doesn't work say new trials

Urban micro-wind doesn’t work in almost all urban contexts and has, on the whole, been poorly deployed and sold for the best part of the last three years. These are two of the objective facts set out in the report of the Encraft Warwick Wind Trials. On publishing the final report into urban m…

Wind power: accessible yet frustrating

Wind power is one of the most accessible and yet frustrating renewable technologies. It is accessible because it’s relatively easy to install, cheaper than many other renewables at small scale; you can buy it at any size from laptop to leviathan; it produces electricity – which is a very fl…

Five ways to recognise a solar shark ... and make sure they don't eat you

It used to be double glazing that was renowned for dodgy salesman. Now some of the techniques they used are being kept alive by companies selling solar thermal panels, heat pumps and wind turbines. The BBC and the Mail on Sunday are just two of the media who have been watching out for fins. T…

Feed-in tariff likely to boost microgeneration

How lovely (and how rare) to be applauding an announcement from the Government. Not only has the newly appointed energy and climate change secretary, Ed Miliband, just committed the UK to the 80 per cent cuts in greenhouse gases by 2050 that scientists say we need, but he’s also promised a feed-…
