Biogas refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source.
Sustainable energy is a principle in which human use of energy "meets the needs of the present without compromising the ability of future generations to meet their own needs." Another definition of sustainable energy is that it is consumed at insignificant rates compared to its supply and with manageable collateral effects, especially environmental effects. Sustainable energy strategies generally have two pillars: cleaner methods of producing energy and energy conservation.
Microgeneration is the small-scale generation of heat and electric power by individuals, small businesses and communities to meet their own needs, as alternatives or supplements to traditional centralized grid-connected power. Although this may be motivated by practical considerations, such as unreliable grid power or long distance from the electrical grid, the term is mainly used currently for environmentally conscious approaches that aspire to zero or low-carbon footprints or cost reduction. It differs from micropower in that it is principally concerned with fixed power plants rather than for use with mobile devices.
The share of energy from renewable sources in gross final consumption of energy continued rising to reach 17% in the European Union in 2016, a doubling of the share attained in 2004 at just 8.5%. The Europe 2020 strategy includes a target of reaching 20% of energy in gross final consumption of energy from renewable sources by 2020 and at least 27% by 2030. These figures are based on energy use in all its forms across all three main sectors, the heating and cooling sector, the electricity sector and the transport sector.
Energy supply is the delivery of fuels or transformed fuels to point of consumption. It potentially encompasses the extraction, transmission, generation, distribution and storage of fuels. It is also sometimes called energy flow.
Good Energy Group PLC is a British energy company based in Chippenham, Wiltshire that generates and purchases renewable electricity, and supplies electricity and gas to homes and businesses throughout the UK. Its CEO is Juliet Davenport.
World energy consumption is the total energy used by the entire human civilization. Typically measured per year, it involves all energy harnessed from every energy source applied towards humanity's endeavours across every single industrial and technological sector, across every country. It does not include energy from food, and the extent to which direct biomass burning has been accounted for is poorly documented. Being the power source metric of civilization, World Energy Consumption has deep implications for humanity's socio-economic-political sphere.
The production of renewable energy in Scotland is an issue that has come to the fore in technical, economic, and political terms during the opening years of the 21st century. The natural resource base for renewable energy is extraordinary by European, and even global standards, with the most important potential sources being wind, wave, and tide.
Renewable energy commercialization involves the deployment of three generations of renewable energy technologies dating back more than 100 years. First-generation technologies, which are already mature and economically competitive, include biomass, hydroelectricity, geothermal power and heat. Second-generation technologies are market-ready and are being deployed at the present time; they include solar heating, photovoltaics, wind power, solar thermal power stations, and modern forms of bioenergy. Third-generation technologies require continued R&D efforts in order to make large contributions on a global scale and include advanced biomass gasification, hot-dry-rock geothermal power, and ocean energy. As of 2012, renewable energy accounts for about half of new nameplate electrical capacity installed and costs are continuing to fall.
Renewable energy in the United Kingdom can be divided into the generation of renewable electricity, the generation of renewable heat and renewable energy use in the transport sector.
China is the world's leading country in electricity production from renewable energy sources, with over double the generation of the second-ranking country, the United States. In 2013 the country had a total capacity of 378 GW of renewable power, mainly from hydroelectric and wind power. China's renewable energy sector is growing faster than its fossil fuels and nuclear power capacity.
Renewable and Sustainable Energy Reviews is a peer-reviewed scientific journal covering research on sustainable energy. It is published in 12 issues per year by Elsevier and the editor-in-chief is L. Kazmerski. According to the Journal Citation Reports, the journal has a 2017 impact factor of 9.184.
Renewable energy in Morocco represented 0.4% of the national energy balance and nearly 10% of electricity production in 2007. Renewable energy is supported by strong hydropower sources and the newly installed wind energy parks. Morocco plans a $13 billion expansion of wind, solar and hydroelectric power generation capacity and associated infrastructure that should see the country get 42% of its electricity from renewable sources by 2020. The Moroccan government is keen on increasing renewable energy production, as Morocco's January–September oil bill reached about USD 1.4 billion in subsidies in 2009, registering a fall of 57.9% compared to 2008.
Energy in Sweden describes energy and electricity production, consumption and import in Sweden. Electricity sector in Sweden is the main article of electricity in Sweden. Swedish climate bill Feb 2017 aims to make Sweden carbon neutral by 2045. Swedish target is to decline emission of climate gases 63% from 1990 to 2030 and international transportation excluding foreign flights 70%. By 2014 just over half of the country's total final energy consumption in electricity, heating and cooling and transport combined was provided by renewables, the highest share amongst the 28 EU member countries.
Variable renewable energy (VRE) is a renewable energy source that is non-dispatchable due to its fluctuating nature, like wind power and solar power, as opposed to a controllable renewable energy source such as hydroelectricity, or biomass, or a relatively constant source such as geothermal power or run-of-the-river hydroelectricity.
Solar power in Mississippi is an underutilized generation method; however, large changes are expected by 2016. The state reached only 1 MW of grid-connected solar electricity in 2013. Rooftop photovoltaics can provide 31.2% of all electricity used in Mississippi from 11,700 MW of solar panels.
Renewable energy in Chile is classified as Conventional and Non Conventional Renewable Energy (NCRE), and includes biomass, hydro-power, geothermal, wind and solar among other energy sources. Most of the time, when referring to Renewable Energy in Chile, it will be the Non Conventional kind.
Wind power in Arkansas remains nearly untapped and as of 2014 no electricity was produced by wind turbines in the state. As of 2015 Arkansas had not established a renewable portfolio standard. Studies conducted conclude that while the state is generally considered to have low resources there are significant pockets throughout the state.
