With energy bills rising here’s two ways to cut the costs and lower your bills!

EcoLocker is set up to keep you informed about renewable energy products and services and then to put you in touch with the right team for your install. Read our user friendly and informative information pages to find out about renewable energy technologies that could help you lower your carbon footprint and save you money.
Here we offer a couple of widely applicable tips to help cut your energy costs.

Get free Insulation:

Before selecting a renewable energy system for your home or business we recommend that you first ensure that your property is fully insulated.
Insulating your home or workplace can significantly reduce bills. Loft insulation for a typical UK home can save you up to £175 a year according to the Energy Saving Trust. Cavity wall insulation adds a further saving of £135 a year!
The Energy Companies Obligation (ECO) is the Government target given to all large energy providers to reduce carbon emissions by improving the energy efficiency of homes in Britain. It is the largest initiative of its kind and even middle / high-income households can take advantage. British gas is offering free insulation worth up to £1000 to all households regardless of their energy supplier. This deal is only available until the end of November and homes have to meet certain criteria to be applicable. Government grants of up to £3500 are also available to those on or below the poverty line.
The warm front scheme pays a company to improve insulation on your loft, cavity walls and hot water tank. To qualify you must receive pension credit with your state pension, have an income below £15,860 and receive Child Tax Credit or Working Tax credits, or claim income support.

Replacing your boiler:

Boilers account for around 55% of our home’s energy bills a year so finding an efficient one or replacing an old one can really help cut your energy costs. If your boiler is more than 15 years old then simply replacing it for an A-rated condensing boiler and improving your heating controls will significantly cut your home’s carbon dioxide emissions and could save you up to £310 a year.
Upgrading to a new A-rated boiler could save you £237 a year according to the comparison website USwitch. So with an initial cost in the region of £1800-£2400 it would take between 7.5 and 10.5 years to cover your investment.
Free Boilers are available via the Energy Companies Obligation (ECO) – Affordable Warmth boiler grant scheme. This scheme is only available to pensioners or senior citizens who receive either State Pension Credits or Working Tax Credits (and are over 60 y/a).
Alternatively you might want to look into Biomass boilers. This type of boiler typically burns wood in the form of wood chips or pellets (see our Biomass Boiler Information pages HERE). They are however, more suited to buildings that aren’t on mains gas and that have space for the storage of fuel.

Take the home energy check at the Energy Saving Trust to find out the overall energy efficiency of your home, and the carbon emissions you produce.

Figures show new record for Renewable Energy power generation in the UK

The department of Energy and Climate Change (DECC) has produced figures earlier in the month that show 15.5% of total electricity generation was from renewable sources in the 2nd quarter of the year.

This has increased 5.8% on the 1012 figures that had previously stood at 9.7%.

“This confirms what we have been seeing for some time, which is renewables steadily becoming more important in meeting our electricity needs, and wind being responsible for the lion’s share of the progress,” Maf Smith, – RenewableUK.

This is a clear sign of progress towards the EU 2020 20% target and is welcomed by industry professionals.

Thinking of an investment in solar panels?

More than 450,000 homes in Britain now have solar panels with an extra 2000 solar panel systems being installed each week. The Great British summer paid off this year, driving up the returns homeowners made on their investment, but can we really still see high percentage returns after the cuts to feed-in tariffs?

The Solar Trade Association estimates a cost saving of £823 a year on an average utility bill for an average £7000 pound investment in solar PV, which equates to roughly a 12.5% tax-free annual return over 25 years.

So what do i need to consider?

The main factors (there are others) to take into consideration when thinking about an investment in solar PV are:

The pitch of your roof. In the summer the angle of the sun is 50 to 60 degrees and the standard UK roof is 30 to 40 degrees resulting in a combined angle of 90 degrees, the ideal angle to catch the most sun.

The direction your roof faces. To produce the most electricity your solar PV array should be facing South. There will be a varying degree in loss of efficiency when pointed more towards the south east or south west.

The type of system you go for. Different makes and models of solar panels will have different efficiency and output ratings, effecting how much power they produce. More expensive solar panels may generate more electricity and generate you more money through the feed-in tariff. In the UK the most popular solar panel manufacturers are Solarworld, Schott, Sharp, Mitsubishi, Yingli and Canadian Solar.

The hours you spend at home. If you are at home during the day you can use more of the electricity you are producing yourself. It can take a decade to cover your initial investment if that is the way you want to look at it, so some thought towards the long term is generally a good idea.

Possible unforeseen maintenance requirements. Many homeowners who invested in solar panels early on, when the FIT first started are now realizing what impact poor install methods had in regards to the returns on their investment. When panels have been installed incorrectly many issues can occur with the roof in which they are installed on, leaks being the major culprit. This can lead to expensive repair bills which are likely to diminish returns considerably. Your chosen installer should reassure you that the method they intend to use on your property will not lead to these issues arising.

All you will need to know can be found HERE but if you have any further questions, then the The Renewable Energy Hub staff are always happy to help.

Increasing debt swamps Solar PV manufacturing Industry in China.

It is thought that China’s solar panel manufacturing industry is not currently sustainable at its current capacity, following pressure due to a substantial drop in demand.

Significant growth in the sector, due to economies across the globe investing heavily in renewable technologies, has resulted in a dramatic drop in prices recently, that European manufacturers blame on cheaper Chinese Solar PV imports.

State-owned Xinhua news agency has reported recently that the government has been refunding a large proportion of VAT to these enterprises to assist with their mounting debts.

86MW Tidal energy project gets approval from Scottish Government.

MeyGen Ltd has just been granted approval by Fergus Ewing the Scottish Energy Minister, to commence the 86MW project, following the completion of the statutory approval process with the regulator Marine Scotland. This is considered a milestone for the joint venture company, with the development being the first phase of a possible 398MW capacity at the Orkney site.

Ewings was quoted saying:

“This is a major step forward for Scotland’s marine renewable energy industry. When fully operational, the 86 MW array could generate enough electricity to power the equivalent of 42,000 homes – around 40 per cent of homes in the Highlands.”

2013-09-25 22_09_57-Technology _ MeyGen

MayGen will install the first six of its AR1000 turbines at the site shortly providing a ‘demonstration array’. The AR1000 is claimed to be the world’s most powerful single-rotor tidal device measuring in at 22.5m in height. It is hoped with the project running to plan, that by 2020 all 400 of the devices could be operational.Schematic Here

The project is located off the north coast of Caithness in the Inner Sound of the Pentland Firth, home to one of Europe’s largest tidal resources.

Dan Pearson, CEO of MeyGen, added:

“the MeyGen team and its shareholders are thrilled to have reached this defining milestone. While there is still much work to be done, the prospects for delivering the first tidal energy array in the Pentland Firth, thereby establishing a stepping stone to commercialising tidal energy, are promising”.

Micro-CHP is set to revolutionise the way that we generate heat and use electricity in homes and small businesses.

Energy efficient, flexible and controllable Micro-CHP systems are being installed in the UK now.

Micro-CHP (micro combined heat and power) is a term referring to a group of technologies that generate both heat and electricity. Like a normal boiler these micro-CHP units can provide heating for your home or office, hot water and electricity as well! Micro-CHP still use mains gas or LPG but are more environmentally friendly and cost effective, plus they give you more control over your home’s heating and electricity consumption. They can also be integrated with conventional condenser boilers, ground and air source heat pumps and solar thermal systems.

Micro-CHP systems are similar in size and shape to domestic boilers; they can be wall hung or floor standing. If you have a conventional boiler then a micro-CHP boiler should be able to directly replace it. The installer must be MCS approved but for the householder there is very little difference in installation and operation. The only difference to a standard boiler is that they are able to generate electricity while they are heating water. A typical domestic system will generate up to 1kW of electricity once warmed up. Any electricity you generate and don’t use can be sold back to the grid whilst getting paid for what you generate by way of the Feed In Tariff (FIT).

Micro-CHP systems lower carbon emissions by generating their own electricity as a by-product of heat. Some systems are eligible for Feed-in Tariffs where you will earn a tariff for each KWH of electricity you generate and each KWH you export. (Click here for the latest FiT rates)

The standard Stirling engine micro-CHP generates about 6:1 heat to electricity so its electrical output is generally fairly low, however the rewards can still be felt, with it paying for itself in a reasonably short amount of time (subject to FIT payments).

The Fuel cell micro-CHP is new to the UK and global markets. Fuel cells work by taking energy from fuel at a chemical level instead of burning it so they don’t produce large quantities of carbon dioxide (or noise). They convert the chemical energy in fuel directly into electricity and heat. They could substantially decarbonise domestic energy production. An initiative by Ceramic Fuel Cells Ltd called ‘free BlueGen’ has been launched which will see fuel cell micro-CHP systems installed for free in the UK. The idea is that the install will be financed by an energy services company and the funds will be recouped through the UK’s feed-in tariff. The end user will only pay for the running costs at a minimum 10% discount on the cheapest local standard retail tariff.

‘The United Kingdom government has announced that it will be increasing its feed-in tariff of micro combined heart and power systems. Micro-CHP systems often make use of hydrogen fuel cells which are capable of producing a large amount of heat while generating electricity. The UK government believes that these systems hold a great deal of potential and could help the country become less dependent on fossil-fuels. The initiative may be good news for Ceramic Fuel Cells, whose BlueGen fuel cells are the only micro-CHP system that has received certification from the Microgeneration Certification Scheme.’ www.viridisec.co.uk

Devon’s Thorne Farm increases EWT’s foothold in the UK.

EWT has installed a direct drive 0.5MW turbine at the Thorne Farm site in Devon recently.

This has seen the Dutch company gain traction in the market, with its 500kW, 61m tip DW52 turbine, now its 50th to be installed in the UK.

The DirectWind 52/54-500kW was developed in response to market demand for sites with low to moderate wind speed. This direct drive technology enables sites that would otherwise have been lost at the initial stages. This is due primarily to the low cut-in speed of 2.5m/s.

Porterledge Renewable Limited (Project developer) has been quoted as saying;

“We originally earmarked the site for a 330kW turbine with 33-metre rotor diameter and a tip height of 53 metres, availability of the 330kW machine came to an end prior to planning permission so we looked for the machine closest in tip height while still in the 500kW turbine class. The EWT DW52 500kW with its tip height of 61m made for an easy route through planning with the bonus of a 60% increase in yield over the 330kW turbine.”




Biomass News – Drastic drafting error affects all new Biomass RHI appliactions.

Today the new RHI regulations came into force, unfortunately for those who plan to install a biomass boiler, a serious error in the drafting of the new regulations means that all biomass installations up to 500kWth will be prevented from receiving the RHI payment. This is down to errors with elements in the regulations that are aimed at emissions and their certification.

All is not lost though as DECC have drafted proposals to rectify the issue with Parliament, when they next sit (sometime in December).

So what does this mean for my Biomass install?

Well if you have ‘fully made’ your application and have been provided with a tariff start date, it seems that this most probably will be honoured by Ofgem*. However, if you are considering installing biomass or are part way through an installation, Ofgem are still taking applications but the chance is they will be delayed until the issue has been rectified. It is therefore best to check directly with Ofgem to see whether/if you should enter details about air quality on the application.
