German Renewable Energy Sources Act
The Renewable Energy Sources Act or EEG () is a series of German laws that originally provided a feed-in tariff (FIT) scheme to encourage the generation of renewable electricity. The specified the transition to an auction system for most technologies which has been finished with the current version EEG 2017. The EEG first came into force on 1April 2000 and has been modified several times since. The original legislation guaranteed a grid connection, preferential dispatch, and a government-set feed-in tariff for 20years, dependent on the technology and size of project. The scheme was funded by a surcharge on electricity consumers, with electricity-intensive manufacturers and the railways later being required to contribute as little as 0.05¢/kWh. For 2017, the unabated EEG surcharge is . In a study in 2011, the average retail price of electricity in Germany, among the highest in the world, stood at around . The EEG was preceded by the Electricity Feed-in Act (1991) which e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Renewable Energy
Renewable energy (also called green energy) is energy made from renewable resource, renewable natural resources that are replenished on a human lifetime, human timescale. The most widely used renewable energy types are solar energy, wind power, and hydropower. Bioenergy and geothermal power are also significant in some countries. Some also consider Nuclear power proposed as renewable energy, nuclear power a renewable power source, although this is controversial, as nuclear energy requires mining uranium, a nonrenewable resource. Renewable energy installations can be large or small and are suited for both urban and rural areas. Renewable energy is often deployed together with further electrification. This has several benefits: electricity can heat pump, move heat and Electric vehicle, vehicles efficiently and is clean at the point of consumption. Variable renewable energy sources are those that have a fluctuating nature, such as wind power and solar power. In contrast, ''contro ...

Landfill Gas
Landfill gas is a mix of different gases created by the action of microorganisms within a landfill as they decompose organic waste, including for example, food waste and paper waste. Landfill gas is approximately forty to sixty percent methane, with the remainder being mostly carbon dioxide. Trace amounts of other volatile organic compounds (VOCs) comprise the remainder (<1%). These trace gases include a large array of species, mainly simple s.Hans-Jürgen Ehrig, Hans-Joachim Schneider and Volkmar Gossow "Waste, 7. Deposition" in Ullmann's Encyclopedia of Industrial Chemistry, 2011, Wiley-VCH, Weinheim. Landfill gases have an influence on .

Biogas
Biogas is a gaseous renewable energy source produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, Wastewater treatment, wastewater, and food waste. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogens inside an Anaerobic digestion, anaerobic digester, biodigester or a bioreactor. The gas composition is primarily methane () and carbon dioxide () and may have small amounts of hydrogen sulfide (), moisture and siloxanes. The methane can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel; it can be used in fuel cells and for heating purpose, such as in cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat. After removal of carbon dioxide and hydrogen sulfide it can be compressed natural gas, compressed in the same way as natural gas and used to power Alternative fuel vehicle, motor vehicles. In the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change Mitigation
Climate change mitigation (or decarbonisation) is action to limit the greenhouse gases in the atmosphere that cause climate change. Climate change mitigation actions include energy conservation, conserving energy and Fossil fuel phase-out, replacing fossil fuels with sustainable energy, clean energy sources. Secondary mitigation strategies include changes to land use and carbon sequestration, removing carbon dioxide (CO2) from the atmosphere. Current climate change mitigation policies are insufficient as they would still result in global warming of about 2.7 °C by 2100, significantly above the 2015 Paris Agreement's goal of limiting global warming to below 2 °C. Solar energy and wind power can replace fossil fuels at the lowest cost compared to other renewable energy options.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

Carbon Dioxide Equivalent
Global warming potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere over a specific time period, relative to carbon dioxide (). It is expressed as a multiple of warming caused by the same mass of carbon dioxide (). Therefore, by definition has a GWP of 1. For other gases it depends on how strongly the gas absorbs thermal radiation, how quickly the gas leaves the atmosphere, and the time frame considered. For example, methane has a GWP over 20 years (GWP-20) of 81.2. meaning that, a leak of a tonne of methane is equivalent to emitting 81.2 tonnes of carbon dioxide measured over 20 years. As methane has a much shorter atmospheric lifetime than carbon dioxide, its GWP is much less over longer time periods, with a GWP-100 of 27.9 and a GWP-500 of 7.95. The carbon dioxide equivalent (e or eq or -e or -eq) can be calculated from the GWP. For any gas, it is the mass of that would warm the earth as much as the mass of that gas. Thus it provides a com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Renewable Energy Laboratory
The National Renewable Energy Laboratory (NREL) in the US specializes in the research and development of renewable energy, energy efficiency, energy systems integration, and sustainable transportation. NREL is a federally funded research and development center sponsored by the Department of Energy and operated by the Alliance for Sustainable Energy, a joint venture between MRIGlobal and Battelle. Located in Golden, Colorado, NREL is home to the National Center for Photovoltaics, the National Bioenergy Center, and the National Wind Technology Center. History Establishment During the 1973 oil crisis, soaring energy prices caused gasoline shortages and contributed significantly to inflation. US President Gerald Ford openly recognized the need for greater energy independence at the September 1974 World Energy Conference in Detroit. A month later, the Solar Energy Research, Development and Demonstration Act of 1974 was signed. Section 10 of the bill explicitly outlined ...

Auctions
An auction is usually a process of Trade, buying and selling Good (economics), goods or Service (economics), services by offering them up for Bidding, bids, taking bids, and then selling the item to the highest bidder or buying the item from the lowest bidder. Some exceptions to this definition exist and are described in the section about different #Types, types. The branch of economic theory dealing with auction types and participants' behavior in auctions is called auction theory. The open ascending price auction is arguably the most common form of auction and has been used throughout history. Participants bid openly against one another, with each subsequent bid being higher than the previous bid. An auctioneer may announce prices, while bidders submit bids vocally or electronically. Auctions are applied for trade in diverse #Contexts, contexts. These contexts include antiques, Art auction, paintings, rare collectibles, expensive wine auction, wines, commodity, commodities, l ...
