Home Wind Power

The integration of energy efficiency measures and renewable energy technology into our home environments is now becoming popular, partly due to rising energy prices but also a greater awareness of the effects of climate change. As demand increases and markets expand the price of micro-scale renewables is likely to come down, making it more affordable for everyone.

This category contains posts about energy efficiency and home renewable energy ideas. It includes posts about micro-scale wind turbines, but also solar energy, ground source heat pumps and other micro-scale technology recognising that wind turbines will not always be appropriate for your home.

Is my Land Suitable for a Wind Turbine?

January 10, 2013

wind turbines

With the UK government feed in tariff (FIT) still looking healthy for smaller wind turbines many people want to know if their land is suitable to host a wind turbine.

There are many contributing factors to a good wind turbine site. The two key factors are wind speed and proximity to an electricity grid connection. Environmental impacts are also very important and proximity to for example hedgerows or buildings where bats may be present will need to be considered.

Wind Speed

You can find out an approximation of the wind speed in your area by inputting your grid co-ordinates into the DECC wind speed database. Be warned however localised physical influences can mean that the wind speed on your land is very different than the DECC predicted average. These influences can include local topography and presence of trees. Trees and undulating terrain can interrupt the flow of the wind and increase turbulence. Generally sites with wind speeds of 7 metres per second or above will be viable for wind turbines if there is a suitable grid connection point nearby.

An accurate wind speed can only be secured by using an on-site anemometer mast, although some wind farm developers have more detailed databases utilising collected mast data. Generally however if you own an open site on relatively high ground or near the coast, your site is likely to have a good wind speed. Clearly if your land is low lying and shielded by hills then wind speed is likely to be poor.

Grid Connection

For turbines in the 100-500kW range, your site needs to be close to a 3 phase electricity supply i.e. within a few hundred metres to 1km. Larger turbines need an 11kV or 33kV supply point within a few km.

Environmental Impacts

Wind turbines should be located away from buildings, trees and hedgerows potentially used by bats. If there are such features in the locality a survey by an expert consultancy showing that impacts will not be significant may need to be carried out. Check this website for a national bat and tree survey company.

Wind energy has widespread public support and offers value for money

February 15, 2012

Wind farm

RenewableUK, the trade association representing the wind, wave and tidal industry, has welcomed the Prime Minister’s public vote of confidence in wind energy, following the publication of a letter by a group of backbench MPs questioning the value of supporting onshore wind. In response to the letter, a Downing Street spokesman said: “We need a low carbon infrastructure and onshore wind is a cost effective and valuable part of the diverse energy mix”.

Jennifer Webber, RenewableUK’s Director of External Affairs said:

“We know there’s a huge amount of public support for wind energy. YouGov conducted a poll in December which showed that 56% of people think we should be expanding wind power in the UK, and 60% believe the Government is right to provide financial support to do so. We’re also glad to see that the wind industry has immediately received strong support from the Government in response to this letter. The Government recognises that, as well as providing a secure source of clean energy, we’re driving our costs down, which will reduce the level of financial support we need in the long term.

It’s official – wind generates “substantially” more electricity

December 22, 2011

Whitlee Wind Farm

The latest Government figures on the amount of electricity generated by wind power have been welcomed by RenewableUK, the country’s largest renewable energy trade association, as proof of the increasingly significant contribution wind energy makes to UK households.

Statistics for the third quarter of 2011, released by the Department of Energy and Climate Change, show that renewable sources generated 9 per cent of the UK’s electricity from July to September. That represents an increase of nearly 1 per cent on the same quarter last year.

The UK now has enough installed capacity to supply more than 3,300,000 homes from wind energy.

Early Renewable Energy Adopters Angry at Government U Turn

November 1, 2010


Early micro-renewable energy generators are angry at the government for doing a U turn on promises relating to feed in tariffs (FITs).

The Tories and LibDems both promised equal FIT rates to early adopters of renewable energy in the run up to the general election. Now the coalition government has gone back on its word and the microgenerator’s campaign is calling on early adopters to let their MPs know how angry they are.

UK Councils to sell Electricity to the Grid

August 16, 2010

From this week the public sector are allowed to sell electricity to the grid in the UK.

The move comes as Energy Secretary Chris Hulne tries to add momentum to the decentralisation of electricity production in the UK via the Feed in Tariff.

The Local Government Act of 1976 previously prevented local councils in England and Wales from selling electricity not produced alongside heat. The UK government now believes that local authorities should be leading the way when it comes to investing in small scale renewable energy.

Hulne said:

Government Criticised for ‘Breaking the Law’ on Renewable Energy & Heat

The UK Micropower Council has criticised the UK government for ‘breaking the law on renewables’. The organisation called on David Cameron to stand by his pledge to be the ‘greenest government ever’.

In a newly published report the Micropower Council claims Local Government Department Ministers have broken the law by failing to comply with an Act of Parliament requiring the implementation of Permitted Development rights for air source heat pumps and micro wind turbines.

UK guaranteed green electricity price tariffs are creating serious interest in small scale renewable energy generation this year.

There is however a group of people not so happy about the detail of the feed in tariff proposals.

For the pioneers who installed their renewable generator before July 15th 2009 the government is offering much lower payments compared with those available to new generators. The original renewable generators will earn 9 pence (US 14 cents) per unit compared with the tariff offering up to 41.3p (US 65 cents) a unit for newly installed generators.

Excitement over Green Energy Fixed Payment Rate

February 1, 2010

small turbine

The UK wind energy sector, householders and community groups have welcomed new fixed electricity payment tariffs for small scale renewable energy technologies announced today. The UK government is set to put in place the ‘feed in’ tariffs for electricity produced by renewable energy projects of up to 5 Megawatts (MW) capacity.

From 1st April this year people and companies who install renewable energy generators of 5 MW or under will receive the guaranteed payments for each kWh of green electricity they produce.

Climate Change Secretary Ed Miliband said:

“The guarantee of getting an income on top of saving on energy bills will be an incentive to householders and communities wanting to make the move to low carbon living.

“The feed-in tariff will change the way householders and communities think about their future energy needs, making the payback for investment far shorter than in the past.

“It will also change the outlook for a range of industries, in particular those in the business of producing and installing small scale low carbon technology.”

Small Wind Turbine Market Expands

November 30, 2009

With fixed prices for electricity generated by small scale renewable energy on their way, are we likely to see a better range of domestic wind turbine models on the market soon?

Over the past ten years there has been a limited range of domestic scale wind turbines on the market, with disaster striking with the B&Q cheap (and ineffective) rooftop turbine. This Youtube video shows a Danish householder with a reasonable plot of land using what appears to be a much more effective stand alone Gaia wind turbine.

The turbine has a peak rated output of 11kW and is described by the manufacturer as suitable for farms, large residences, offices, small businesses and public buildings where the main aim is to reduce the amount of electricity imported. In the right locations exporting electricity is also possible. The turbine has been designed to give an optimum yield in moderate wind speeds which the manufacturer specifies as a range of between 4.5-7.5 m/s (10-12mph).

Planning Rules Change for Small -Scale Renewables

November 19, 2009

Should people need planning consent for small scale renewable energy? This is a question the UK government has been contemplating for several years.

In 2008, the Town and Country Planning Order was amended to grant permitted development rights to domestic properties for solar panels, ground source heat pumps and water source heat pumps, but not to wind turbines and air source heat pumps.

A new consultation was kicked off yesterday on Government proposals to introduce permitted development rights for small scale renewable energy and low carbon technologies for both householders and businesses. It is also looking for feedback on permitted development rights and advertisement consent for electric vehicle charging infrastructure.

Can our Grid System Cope with Domestic Renewable Energy?

September 6, 2009

electricity power lines

With more people wanting to be energy self sufficient and goverments providing financial incentives to make this ideal more affordable, we are looking at a future where domestic energy generation is rolled out to the masses.

In the UK, National Grid operate the high level grid infrastructure (generally any substations, power lines or cables rated at above 132kV) and distribution network organisations operate the local grid infrastructure of 132kV and below in the different regions.

With this anticipated increase in households generating their own green electricity, so will come increasing demands to connect these individual generators to the local distribution networks. Domestic generators such as solar PV panels, micro-wind turbines, or micro-scale CHP units will have the potential to export small amounts of electricity (as little as 0.5 kW). The result will be far more complex, actively managed local electricity networks, in which power flows in different directions at different times. Ensuring that distribution operators are ready for this change represents a major challenge.
