Wood Energy is one of the UK's leading wood-fuel heating businesses, providing over a third of the country's total wood heat capacity and saving almost 12,000 tonnes of CO2 emissions a year through its boiler installations. Based in Devon, the company helped to set up the UK's only accredited wood-fuel training course for the industry to help raise standards. It has also worked hard to ensure a reliable supply of fuel for the heating systems it installs, by supporting local wood-fuel supply businesses and pellet mills. Benefiting from the growing demand for wood-fuel -- which is now cheaper than fossil fuels -- the business is helping the UK meet its carbon reduction targets.

Earth Report Payback Time Feed-In Tariff for Renewables
Householders installing wind turbines and solar panels must wait many years for a pay-back on their investment. In Germany they've found a way to cut down that pay-back time. It's called a feed-in tariff and it is giving a big boost to the renewables industry. Under German law, householders with operating solar or wind power can sell their spare capacity back to power companies at a premium. Demand for renewable energy systems is up, and as the numbers increase the installation costs are steadily falling. Forty countries now follow the German lead, including the UK.
The UK Feed In Tariff Explained
Home electricity providers can be paid back by their utility company by exporting electricity to the grid. Save money on utility bills using this method known as the Feed In Tariff.
This video explains the principles behind feed-in-tariffs in the UK introduced in 2010. Solar panel (PV) photovoltaics can be used to generate electricity and power for your home or business. Find out more about feed in tariffs here.

UK Solar Feed-in Tariff Explained
The UK Feed-in Tariff, or Clean Energy Cashback, for solar energy, explained.
The UK 'Feed-in Tariff' is a government backed policy to encourage the uptake of renewable energy in the UK.
Instead of providing a grant to help you buy a solar system, the 'Feed-in Tariff' rewards you for the amount of energy you generate, regardless of whether you consume the electricity or not. The scheme also provides an additional payment for any electricity you export.
Under the Feed-in Tariff, an average home in the UK, with a 2.5kWp (21M2) system installed can earn around £900 a year generating and exporting its own solar electricity. You can also save around £130 a year on your electricity bill.

Good Energy, UK, Renewable electricity
Good Energy has set up the 'Home Generation' scheme, which gives payments to small-scale renewable energy generators for all the electricity which they generate, thus encouraging more renewable generation at a local level.
Large-scale renewable energy generators in the UK set up commercial contracts to sell their electricity, and can also claim Renewable Obligation Certificates (ROCs), which currently sell for about £39 per MWh (3.9 p per kWh). However, for small renewable generators, the time and effort to do this may not be justified by the financial return. In addition, ROCs can be claimed only on an annual generation of 500 kWh or more, which excludes very small generators.
Good Energy has therefore set up the Home Generation scheme, which provides a payment of 4.5p per kWh to small renewable generators for all the electricity which they generate. To join the scheme, generators must buy the rest of their electricity from Good Energy, and must install a simple meter to measure the total kWh generated. Home Generation customers greatly appreciate the simplicity of this scheme, and typically earn about £100 per year through it. There are currently 200 generators in the Home Generation scheme, representing a total installed capacity of 440 kW.
Good Energy set up the scheme as part of their commitment to increasing the use of renewable electricity in the UK. They have used their extensive knowledge of the practicalities of local generation to lobby the electricity regulator and other suppliers, to make the rules for exporting electricity clearer and to negociate a better deal for small generators.

Seaton Primary School, UK, a sustainable school
Seaton Primary School in Devon lives out its school motto of 'Caring now for the Future', and is one of a few UK schools to install a range of renewable technologies. A 2.5 kW wind turbine and a 4.7 kW PV array on the roof of the school hall supply electricity directly to the school and have helped reduce CO2 emissions by about 2 tonnes a year. In addition, 48 m2 of solar water heating panels heat the school's outdoor swimming pool. Other green initiatives include class 'Energy Agents' to help reduce energy waste; the after-school 'Eco Club' to monitor energy use; a 2006 Energy Audit resulting in a host of energy efficiency measures; an orchard to provide fruit for pupils and save food miles; and a grey water collection system to supply the school wildlife pond and demonstrate small-scale water power.

Kirklees MBC, UK, Domestic solar pv electricity
Kirklees Metropolitan Borough Council (MBC) has undertaken the largest photovoltaic (PV) programme in the UK, with 351 kWp of PV installed on social housing, community buildings and luxury flats.
Photovoltaics are the easiest renewable energy technology to integrate in towns and cities, because they can be installed on roofs and building facades with minimal intrusion, and they have the highest acceptance by the general public. They are now widely used in Germany and the Netherlands. Starting in 2000, Kirklees MBC, based in Huddersfield, took part in a major European project to supply electricity from PV in city buildings. The EU-funded SunCities Project contributed to the installation of 351 kWp of PV (also solar thermal systems) on a range of private and public-sector housing and residential homes in Huddersfield. This is the largest domestic PV programme in the UK, and represents about 5% of installed PV capacity. All buildings were either refurbished or newly built to high environmental standards, so households gained the benefits of energy efficiency as well as the more visible PV.
A typical household system rated at 1 kWp generates about 750 kWh of electricity per year in the UK, which would give a saving of £50 per year if it all replaced imported electricity. Kirkless MBC has lobbied to get better payment for export of electricity, and also easier access to Renewable Obligation Certificates (ROCs) for small generators.

Code for Sustainable Homes Energy and CO2 Emissions
Discusses the targets related to CO2 emissions and how close we are to actually meeting said targets in the UK.
The Code for Sustainable Homes sets standards for the environmental performance of dwellings, and comprises nine categories. The first category, 'Energy and CO2 Emissions', seeks to minimise the operational energy used within the home, and the resulting emissions of carbon dioxide to the atmosphere.
Under the Kyoto Protocol of 1997, the core of the commitment required was for developed countries to reduce their emissions by 5%, based on 1990 levels of emissions. The three principal means of implementing Kyoto are emissions trading, clean development mechanisms and joint implementation. In particular, the emissions trading scheme means putting a cap on carbon and giving everyone an allowance. People who don't need the full allowance can then sell it on to those who need more, so a market is created, leading to more innovation and efficiency.
The 'Energy and CO2 Emissions' category in the Code for Sustainable Homes aims to push people to build low carbon homes, so that they're more likely to use fuels which emit less carbon, and insulate their properties so that less carbon is emitted.
The 'Energy and CO2 Emissions' category is probably the most complicated or extensive of all the categories in the Code. The Code levels are rated at level 1 to 6, sometimes referred to as level 1* to 6* rating. Where level 1 is a poorly performing house in terms of its emissions, level 3 equates to the old, phased-out BRE EcoHomes 'very good' rating, and level 6 is effectively a zero carbon property. The objective of the Code therefore is to reduce carbon emissions and increase the Code level rating. In order to do this there are several aspects of the carbon-producing and energy-consuming functions of the building to consider; these are the Dwelling Emission Rate (DER), the building fabric, internal lighting, drying spaces, energy labelled white goods, external lighting, low or zero carbon (LZC) technologies, cycle storage and the home office.

BioRegional Development Group, UK, Wood-chip from waste
The BioRegional Development Group has established a 'TreeStation' -- a centre where waste wood is received from many sources, turned into wood-chip and delivered for use as a heating fuel. Until recently, their site capacity was about 2,500 tonnes per year, but a new chipper has increased this to 15,000 tonnes per year.
Legislation in the London Borough of Croydon and other boroughs requires all significant new building developments to generate 10% of their energy from on-site renewable sources. Biomass heating is one of the most cost-effective ways to do this, but requires a reliable supply of fuel. The London boroughs do have a considerable resource of fuelwood from the management of parks, gardens and woodland, but much of the waste produced is currently sent to landfill, at a cost of about £40 per tonne.
The BioRegional Development Group brokered an innovative deal between tree surgery business, City Suburban Tree Surgeons Ltd, and Croydon Council to manage and dispose of all the Council's wood waste. BioRegional established a TreeStation -- a centre where waste wood is received from many sources, turned into wood-chip and delivered for use as a fuel for heating and combined heat-and-power. Until recently, the TreeStation had produced about 2,500 tonnes of wood-chip per year for a single customer, Slough Heat and Power, who supply heat and electricity to Slough Estates and use an increasing amount of wood in their fuel supply. With recent equipment, the TreeStation now has the capacity to process 15,000 tonnes per year. BioRegional is also setting up drying facilities so that the wood-chip will have lower moisture content, and so be suitable for a wide range of boilers.

Solar water heating, Legionella and heating daily to the store base
Solar water heating systems using comnventional hot water stores are reported by a UK government water safety agency WRAS as being highly likely to be creating a Legionella safety risk. Legionnnaire's disease risk can be minimised by improved design. One safer solar storage solution used by Solartwin is called dedicated solar volume in time. This safer design involves heating to the base of a solar hot water store every day in the evening to 60C. This solar hot water storage method fullly complies with regulation UK HSE Legionella L8 guidance para 158. Another safer solution is a thermal store. The safety principles also apply to heat pumps. Includes a suggested way to calculate the statistical number of people infected with Legionella per year from solar cylinders in UK.
