Energy Hierarchy
The Energy Hierarchy is a classification of energy options, prioritised to assist progress towards a more sustainable energy system. It is a similar approach to the waste hierarchy for minimising resource depletion, and adopts a parallel sequence. The highest priorities cover the prevention of unnecessary energy usage both through eliminating waste and improving energy efficiency. The sustainable production of energy resources is the next priority. Depletive and waste-producing energy generation options are the lowest priority. For an energy system to be sustainable: the resources applied to producing the energy must be capable of lasting indefinitely; energy conversion should produce no harmful by-products, including net emissions, nor wastes which cannot be fully recycled; and it must be capable of meeting reasonable energy demands. Energy saving The top priority under the Energy Hierarchy is energy conservation or the prevention of unnecessary use of energy. This category ...

Climate Change Mitigation
Climate change mitigation is action to limit climate change by reducing Greenhouse gas emissions, emissions of greenhouse gases or Carbon sink, removing those gases from the atmosphere. The recent rise in global average temperature is mostly caused by emissions from fossil fuels burning (coal, oil, and natural gas). Mitigation can reduce emissions by energy transition, transitioning to sustainable energy sources, energy conservation, conserving energy, and Efficient energy use, increasing efficiency. In addition, can be carbon dioxide removal, removed from the atmosphere by carbon sink, enlarging forests, Wetland restoration, restoring wetlands and using other natural and technical processes, which are grouped together under the term of carbon sequestration. Solar energy and wind power have the highest climate change mitigation potential at lowest cost compared to a range of other options. Variable availability of sunshine and wind is addressed by energy storage and improved elec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Transport Hierarchy
The green transport hierarchy (Canada), street user hierarchy (US), sustainable transport hierarchy (Wales), urban transport hierarchy or road user hierarchy (Australia, UK) is a hierarchy of modes of transport of road users prioritising green transport. It is the basic concept of transport reform groups worldwide. In 2020, the UK government consulted about adding to the Highway Code a ''road user hierarchy'' prioritising pedestrians. It is a key characteristic of Australian transport planning. History ''The Green Transportation Hierarchy: A Guide for Personal & Public Decision-Making'' by Chris Bradshaw was first published September 1994 and revised June 2004. It was first prepared for ''Ottawalk'' and the ''Transportation Working Committee of the Ottawa-Carleton Round-table on the Environment'' in January 1992, only stating 'Walk, Cycle, Bus, Truck, Car'.

Energy Policy
Energy policy is the manner in which a given entity (often governmental) has decided to address issues of energy development including energy conversion, distribution and use as well as reduction of greenhouse gas emissions in order to contribute to climate change mitigation. The attributes of energy policy may include legislation, international treaties, incentives to investment, guidelines for energy conservation, taxation and other public policy techniques. Energy is a core component of modern economies. A functioning economy requires not only labor and capital but also energy, for manufacturing processes, transportation, communication, agriculture, and more. Energy planning is more detailed than energy policy. Energy policy is closely related to climate change policy because totalled worldwide the energy sector emits more greenhouse gas than other sectors. Purposes Access to energy is critical for basic social needs, such as lighting, heating, cooking, and healthcare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Law
Energy laws govern the use and taxation of energy, both renewable energy, renewable and non-renewable energy, non-renewable. These laws are the primary authority, primary authorities (such as caselaw, statutes, rules, regulations and edicts) related to energy. In contrast, energy policy refers to the policy and politics of energy. Energy law includes the legal provision for oil, gasoline, and "extraction taxes." The practice of energy law includes contracts for siting, extraction, licenses for the acquisition and property law, ownership rights in oil and natural gas, gas both under the soil before discovery and after its rule of capture, capture, and adjudication regarding those rights. Renewable energy law International law There is a growing academic interest in international energy law, including continuing legal education seminars, treatises, law reviews, and graduate courses. In the same line, there has been growing interest on energy-specific issues and their partic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Renewable Energy Association
The Association for Renewable Energy and Clean Technology, previously known as Renewable Energy Association (REA), is a renewable energy and clean technology trade association in the UK encompassing all of renewables industry in the United Kingdom. REA covers renewable power & flexibility, heat and cooling, circular bioresources and transport. The REA is a not-for-profit company. History The Renewable Power Association was established in 2001 as a not-for-profit trade association, representing British renewable energy producers and promoting the use of renewable energy in the UK. The company changed its name in November 2005 to ''Renewable Energy Association''. Renewable Energy Association was merged with the Association for Organics Recycling (AfOR) in September 2012, the latter becoming the "Organics Recycling Group" under REA. The Company name was officially changed again to ''The Association for Renewable Energy and Clean Technology'' in October 2019. Activities L ...

Philip Wolfe (engineer)
Philip Rowland Wolfe MBE is one of the pioneers of the British renewable energy sector. He first became involved in the 1970s, leading various photovoltaics companies until the turn of the century. As Director-General of the Renewable Energy Association he led the campaign for Feed-in Tariffs and the Renewable Heat Incentive. He has written many publications and is responsible for a number of innovations and initiatives. He was appointed Member of the Order of the British Empire (MBE) in the 2016 New Year Honours for services to renewable energy and the energy sector. Sustainable energy policy The campaign for the introduction of the Renewable Heat Incentive and Feed-in tariffs in the United Kingdom was led by Friends of the Earth and the Renewable Energy Association, when Philip Wolfe was Director General, between 2003 and 2009. He edited the first blueprint for these measures to assist early government drafting. He first proposed the Energy hierarchy, and initiated the consu ...

Offsetting
A carbon offset is a reduction or removal of emissions of carbon dioxide or other greenhouse gases made in order to compensate for emissions made elsewhere. Offsets are measured in tonnes of carbon dioxide-equivalent (CO2e). One ton of carbon offset represents the reduction or removal of one ton of carbon dioxide or its equivalent in other greenhouse gases. One of the hidden dangers of climate change policy is unequal prices of carbon in the economy, which can cause economic collateral damage if production flows to regions or industries that have a lower price of carbon—unless carbon can be purchased from that area, which offsets effectively permit, equalizing the price. Within the voluntary market, demand for carbon offset credits is generated by individuals, companies, organizations, and sub-national governments who purchase carbon offsets to mitigate their greenhouse gas emissions to meet carbon neutral, net-zero or other established emission reduction goals. The voluntar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radioactive Waste
Radioactive waste is a type of hazardous waste that contains radioactive material. Radioactive waste is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, rare-earth mining, and nuclear weapons reprocessing. The storage and disposal of radioactive waste is regulated by government agencies in order to protect human health and the environment. Radioactive waste is broadly classified into low-level waste (LLW), such as paper, rags, tools, clothing, which contain small amounts of mostly short-lived radioactivity, intermediate-level waste (ILW), which contains higher amounts of radioactivity and requires some shielding, and high-level waste (HLW), which is highly radioactive and hot due to decay heat, so requires cooling and shielding. In nuclear reprocessing plants about 96% of spent nuclear fuel is recycled back into uranium-based and mixed-oxide (MOX) fuels. The residual 4% is minor actinides and fission products the latter of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Capture And Storage
Carbon capture and storage (CCS) or carbon capture and sequestration is the process of capturing carbon dioxide (CO2) before it enters the atmosphere, transporting it, and storing it (carbon sequestration) for centuries or millennia. Usually the CO2 is captured from large point sources, such as a chemical plant or biomass power plant, and then stored in an underground geological formation. The aim is to prevent the release of CO2 from heavy industry with the intent of mitigating the effects of climate change. CO2 has been injected into geological formations for several decades for enhanced oil recovery and after separation from natural gas, but this has been criticised for producing more emissions when the gas or oil is burned. Carbon capture and utilization (CCU) and CCS are sometimes discussed collectively as carbon capture, utilization, and sequestration (CCUS). This is because CCS is a relatively expensive process yielding a product which is often too cheap. Hence, car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Crop
Energy crops are low-cost and low-maintenance crops grown solely for energy production by combustion (not for food). The crops are processed into solid, liquid or gaseous fuels, such as pellets, bioethanol or biogas. The fuels are burned to generate electrical power or heat. The plants are generally categorized as woody or herbaceous. Woody plants include willow and poplar, herbaceous plants include '' Miscanthus x giganteus'' and ''Pennisetum purpureum'' (both known as elephant grass). Herbaceous crops, while physically smaller than trees, store roughly twice the amount of CO2 (in the form of carbon) below ground compared to woody crops. Through biotechnological procedures such as genetic modification, plants can be manipulated to create higher yields. Relatively high yields can also be realized with existing cultivars. However, some additional advantages such as reduced associated costs (i.e. costs during the manufacturing process) and less water use can only be accompli ...

Bioenergy
Biomass is plant-based material used as a fuel for heat or electricity production. It can be in the form of wood, wood residues, energy crops, agricultural residues, and waste from industry, farms, and households. Some people use the terms biomass and biofuel interchangeably, while others consider biofuel to be a ''liquid'' or ''gaseous'' fuel used for transportation, as defined by government authorities in the US and EU. The European Union's Joint Research Centre defines solid biofuel as raw or processed organic matter of biological origin used for energy, such as firewood, wood chips, and wood pellets. In 2019, biomass was used to produce 57 EJ (exajoules) of energy, compared to 190 EJ from crude oil, 168 EJ from coal, 144 EJ from natural gas, 30 EJ from nuclear, 15 EJ from hydropower, hydro and 13 EJ from wind power, wind, solar power, solar and geothermal energy, geothermal combined. Approximately 86% of modern bioenergy is used for heating applications, with 9% used for tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
