Renewable Heat Incentive
The Renewable Heat Incentive (the RHI) is a payment system in England, Scotland and Wales, for the generation of heat from renewable energy sources. Introduced on 28 November 2011, the RHI replaces the Low Carbon Building Programme, which closed in 2010. The RHI operates in a similar manner to the Feed-in Tariff system, and was introduced through the same legislation - the Energy Act 2008. In the first phase of the RHI cash payments are paid to owners who install renewable heat generation equipment in non-domestic buildings: Commercial RHI. The RHI went live on 28 November 2011 for non domestic buildings. The Coalition Government confirmed its support for the RHI in the October 2010 Spending Review and published details on 10 March 2011. The RHI was extended to domestic buildings on 9 April 2014 after a further series of delays. Three consultations were launched which included proposed domestic tariffs and a long discussion on eligible technologies along with changes to the Non-dome ...

Ground Source Heat Pumps
A ground source heat pump (also geothermal heat pump) is a heating/cooling system for buildings that uses a type of heat pump to transfer heat to or from the ground, taking advantage of the relative constancy of temperatures of the earth through the seasons. Ground source heat pumps (GSHPs) – or geothermal heat pumps (GHP) as they are commonly termed in North America – are among the most energy-efficient technologies for providing HVAC and water heating, using far less energy than can be achieved by burning a fuel in a boiler/furnace or by use of resistive electric heaters. Efficiency is given as a coefficient of performance (CoP) which is typically in the range 3 – 6, meaning that the devices provide 3 – 6 units of heat for each unit of electricity used. Setup costs are higher than for other heating systems due to the requirement to install ground loops over large areas or drill bore holes, and for this reason air source heat pumps are often used instead.

Renewable Energy In England
A renewable resource, also known as a flow resource, is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale. When the recovery rate of resources is unlikely to ever exceed a human time scale, these are called perpetual resources. Renewable resources are a part of Earth's natural environment and the largest components of its ecosphere. A positive life-cycle assessment is a key indicator of a resource's sustainability. Definitions of renewable resources may also include agricultural production, as in agricultural products and to an extent water resources.What are “Renewable Resources”? by A. John Armstrong, Esq. & Dr. Jan H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feed-in Tariffs In The United Kingdom
A feed-in tariff is when payments are given by energy suppliers if a property or organisation generates their own electricity using technology such as solar panels or wind turbines and feeds any surplus back to the grid. In the United Kingdom, they were entered into law by the Energy Act 2008 and took effect from April 2010.Gipe, P"Britain to Launch Innovative Feed-in Tariff Program in 2010"/ref> The scheme closed to new applicants on 31 March 2019. Scope The Feed-In Tariff applies to small-scale generation of electricity using eligible renewable technologies. To encourage development of these technologies, feed-in tariffs pay the generator a certain amount even for energy which the generator themselves consumes. Electricity fed into the grid receives an additional export tariff, currently (May 2020) 5.24p per kWh. Costs for the programme are borne by all British electricity consumers proportionally: all consumers will bear a slight increase in their annual bill, thus allowing e ...

Boiler Scrappage Scheme
The UK boiler scrappage scheme was a scrappage scheme to subsidise up to 125,000 English households to install newer, fuel-efficient heating systems and stay warm without wasting energy. Each qualifying household would receive a £400 grant. Households that took part were expected to save between £200 and £235 a year on fuel bills, cut their carbon emissions and sustain work for the heating industry. The scheme was announced by the Chancellor Alistair Darling in a Pre-Budget Report at the end of 2009 and launched on 5 January 2010. A similar vehicle scrappage scheme had already been announced in the 2009 budget. The total cost was to be £50 million, with a further £150 million for the Warm Front Scheme. To qualify, one had to live in England and have a working G-rated boiler. Successful applicants received a voucher for £400 off the price of either a modern A-rated boiler or a renewable heating system (such as a biomass boiler, heat pump or micro CHP). After a completed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Renewable Heat Incentive Scandal
The Renewable Heat Incentive scandal (RHI scandal), also referred to as RHIgate and the Cash for Ash scandal, is a political scandal in Northern Ireland that centres on a failed renewable energy (wood pellet burning) incentive scheme that has been reported to potentially cost the public purse almost £500 million. The plan, initiated in 2012, was overseen by Arlene Foster of the Democratic Unionist Party (DUP), the then-Minister for Enterprise, Trade and Investment. Foster failed to introduce proper cost controls, allowing the plan to spiral out of control. The scheme worked by paying applicants to use renewable energy. However, the rate paid was more than the cost of the fuel, and thus many applicants were making profits simply by heating their properties. The political scandal first came to light in November 2016, by which point Foster had become Northern Ireland's First Minister. Foster refused to resign or stand aside during any inquiry, saying that to do so would be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biomass Heating Systems
Biomass heating systems generate heat from biomass. The systems fall under the categories of: *direct combustion, * gasification, * combined heat and power (CHP), *anaerobic digestion, * aerobic digestion. Benefits of biomass heating The use of biomass in heating systems is beneficial because it uses agricultural, forest, urban and industrial residues and waste to produce heat and/or electricity with less effect on the environment than fossil fuels. This type of energy production has a limited long-term effect on the environment because the carbon in biomass is part of the natural carbon cycle; while the carbon in fossil fuels is not, and permanently adds carbon to the environment when burned for fuel ( carbon footprint). Historically, before the use of fossil fuels in significant quantities, biomass in the form of wood fuel provided most of humanity's heating. A potential source of biomass heating that is the subject of research is cellulose hydrolysis and monomerization as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Source Heat Pump
A heat pump is a device that can heat a building (or part of a building) by transferring thermal energy from the outside using a refrigeration cycle. Many heat pumps can also operate in the opposite direction, cooling the building by removing heat from the enclosed space and rejecting it outside. Units that only provide cooling are called air conditioners. When in heating mode, a refrigerant at outside temperature is being compressed. As a result, the refrigerant becomes hot. This thermal energy can be transferred to an indoor unit. After being moved outdoors again, the refrigerant is decompressed — evaporated. It has lost some of its thermal energy and returns colder than the environment. It can now take up the surrounding energy from the air or from the ground before the process repeats. Compressors, fans, and pumps run with electric energy. Common types are air-source heat pumps, ground-source heat pumps, water-source heat pumps and exhaust air heat pumps. They are als ...

Solar Thermal
Solar thermal energy (STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in industry, and in the residential and commercial sectors. Solar thermal collectors are classified by the United States Energy Information Administration as low-, medium-, or high-temperature collectors. Low-temperature collectors are generally unglazed and used to heat swimming pools or to heat ventilation air. Medium-temperature collectors are also usually flat plates but are used for heating water or air for residential and commercial use. High-temperature collectors concentrate sunlight using mirrors or lenses and are generally used for fulfilling heat requirements up to 300 deg C / 20 bar pressure in industries, and for electric power production. Two categories include Concentrated Solar Thermal (CST) for fulfilling heat requirements in industries, and Concentrated Solar Power (CSP) when the heat collected is used for electric power generation. C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feed-in Tariff
A feed-in tariff (FIT, FiT, standard offer contract,Couture, T., Cory, K., Kreycik, C., Williams, E., (2010)Policymaker's Guide to Feed-in Tariff Policy Design National Renewable Energy Laboratory, U.S. Dept. of Energy advanced renewable tariff, or renewable energy payments) is a policy mechanism designed to accelerate investment in renewable energy technologies by offering long-term contracts to renewable energy producers. This means promising renewable energy producers an above-market price and providing price certainty and long-term contracts that help finance renewable energy investments. Typically, FITs award different prices to different sources of renewable energy in order to encourage development of one technology over another. For example, technologies such as wind power and solar PV are awarded a higher price per kWh than tidal power. FITs often include a "degression": a gradual decrease of the price or tariff in order to follow and encourage technological cost reductions ...

Renewable Heat
Renewable heat is an application of renewable energy referring to the generation of heat from renewable sources; for example, feeding radiators with water warmed by focused solar radiation rather than by a fossil fuel boiler. Renewable heat technologies include renewable biofuels, solar heating, geothermal heating, heat pumps and heat exchangers. Insulation is almost always an important factor in how renewable heating is implemented. Many colder countries consume more energy for heating than for supplying electricity. For example, in 2005 the United Kingdom consumed 354 TWh of electric power, but had a heat requirement of 907 TWh, the majority of which (81%) was met using gas. The residential sector alone consumed 550 TWh of energy for heating, mainly derived from methane. Almost half of the final energy consumed in the UK (49%) was in the form of heat, of which 70% was used by households and in commercial and public buildings. Households used heat mainly for space he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
District Heating
District heating (also known as heat networks or teleheating) is a system for distributing heat generated in a centralized location through a system of insulated pipes for residential and commercial heating requirements such as space heating and water heating. The heat is often obtained from a cogeneration plant burning fossil fuels or biomass, but heat-only boiler stations, geothermal heating, heat pumps and central solar heating are also used, as well as heat waste from factories and nuclear power electricity generation. District heating plants can provide higher efficiencies and better pollution control than localized boilers. According to some research, district heating with combined heat and power (CHPDH) is the cheapest method of cutting carbon emissions, and has one of the lowest carbon footprints of all fossil generation plants. Fifth-generation district heat networks do not use combustion on-site and have zero emissions of CO and NO on-site; they employ heat transfer u ...
