Centre For Alternative Technology
The Centre for Alternative Technology (CAT) ( cy, Canolfan y Dechnoleg Amgen) is an eco-centre in Powys, mid-Wales, dedicated to demonstrating and teaching sustainable development. CAT, despite its name, no longer concentrates its efforts exclusively on alternative technology, but provides information on all aspects of sustainable living. It is open to visitors, offers postgraduate degrees as well as shorter residential and one day courses; and publishes information on renewable energy, sustainable architecture, organic farming, gardening, and sustainable living. CAT also runs education programmes for schools and sells environmentally friendly items through its on site shop, restaurant and mail order department. History CAT was founded by businessman-turned-environmentalist Gerard Morgan-Grenville, and opened in 1973 in the disused Llwyngwern slate quarry near Machynlleth (once served by the narrow-gauge Corris Railway), where it occupies a seven-acre (28,000 m2) site.

Registered Charity
A charitable organization or charity is an organization whose primary objectives are philanthropy and social well-being (e.g. educational, religious or other activities serving the public interest or common good). The legal definition of a charitable organization (and of charity) varies between countries and in some instances regions of the country. The regulation, the tax treatment, and the way in which charity law affects charitable organizations also vary. Charitable organizations may not use any of their funds to profit individual persons or entities. (However, some charitable organizations have come under scrutiny for spending a disproportionate amount of their income to pay the salaries of their leadership). Financial figures (e.g. tax refund, revenue from fundraising, revenue from sale of goods and services or revenue from investment) are indicators to assess the financial sustainability of a charity, especially to charity evaluators. This information can impact a char ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Small Is Beautiful
''Small Is Beautiful: A Study of Economics As If People Mattered'' is a collection of essays published in 1973 by German-born British economist E. F. Schumacher. The title "Small Is Beautiful" came from a principle espoused by Schumacher's teacher Leopold KohrDr. Leopold Kohr, 84; Backed Smaller States obituary, 28 February 1994. (1909–1994) advancing small, , policies, and polities as a superior alternative to the mainstream ethos of "bigger is better". ...

Organic Gardening
Organic horticulture is the science and art of growing fruits, vegetables, flowers, or ornamental plants by following the essential principles of organic agriculture in soil building and conservation, pest management, and heirloom variety preservation. The Latin words ''hortus'' (garden plant) and ''cultura'' (culture) together form ''horticulture'', classically defined as the culture or growing of garden plants. ''Horticulture'' is also sometimes defined simply as "agriculture minus the plough". Instead of the plough, horticulture makes use of human labour and gardener's hand tools, although some small machine tools like rotary tillers are commonly employed now. General Mulches, cover crops, compost, manures, vermicompost, and mineral supplements are soil-building mainstays that distinguish this type of farming from its conventional counterpart. Through attention to good healthy soil condition, it is expected that insect, fungal, or other problems that sometimes plague plants ca ...

Low-energy House
A low-energy house is characterized by an energy-efficient design and technical features which enable it to provide high living standards and comfort with low energy consumption and carbon emissions. Traditional heating and active cooling systems are absent, or their use is secondary. Low-energy buildings may be viewed as examples of sustainable architecture. Low-energy houses often have active and passive solar building design and components, which reduce the house's energy consumption and minimally impact the resident's lifestyle. Throughout the world, companies and non-profit organizations provide guidelines and issue certifications to guarantee the energy performance of buildings and their processes and materials. Certifications include passive house, BBC - Bâtiment Basse Consommation - Effinergie (France), zero-carbon house (UK), and Minergie (Switzerland). Background During the 1970s, experimental initiatives for low-energy buildings were made in Denmark, the United State ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Power
Wind power or wind energy is mostly the use of wind turbines to electricity generation, generate electricity. Wind power is a popular, sustainable energy, sustainable, renewable energy source that has a much smaller Environmental impact of wind power, impact on the environment than burning fossil fuels. Historically, wind power has been used in sails, windmills and windpumps but today it is mostly used to generate electricity. Wind farms consist of many individual wind turbines, which are connected to the electric power transmission Electrical grid, network. New Onshore wind farm, onshore (on-land) wind farms are cheaper than new Coal-fired power station, coal or Gas-fired power plant, gas plants, but expansion of wind power is being hindered by fossil fuel subsidies. Onshore wind farms have a greater visual #Impact on environment and landscape, impact on the landscape than some other power stations.

Hydropower
Hydropower (from el, ὕδωρ, "water"), also known as water power, is the use of falling or fast-running water to Electricity generation, produce electricity or to power machines. This is achieved by energy transformation, converting the Potential energy, gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for Hydroelectricity, hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce Carbon dioxide in Earth's atmosphere, carbon dioxide or other Air pollution, atmospheric pollutants and it provides a relatively consistent source of power. Nonetheless, it has economic, sociological, and environmental downsides and requires a sufficiently energetic source of water, such as a river or elevated lake. Int ...

Solar Power
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine. Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar electricity has fallen, grid-connected solar PV systems have grown more or less exponentially. Millions of installations and gigawatt-scale photovoltaic power stations continue to be built, with half of new generation capacity being solar in 2021. ...

Funicular
A funicular (, , ) is a type of cable railway system that connects points along a railway track laid on a steep slope. The system is characterized by two counterbalanced carriages (also called cars or trains) permanently attached to opposite ends of a haulage cable, which is looped over a pulley at the upper end of the track. The result of such a configuration is that the two carriages move synchronously: as one ascends, the other descends at an equal speed. This feature distinguishes funiculars from inclined elevators, which have a single car that is hauled uphill. The term ''funicular'' derives from the Latin word , the diminutive of , meaning 'rope'. Operation In a funicular, both cars are permanently connected to the opposite ends of the same cable, known as a ''haul rope''; this haul rope runs through a system of pulleys at the upper end of the line. If the railway track is not perfectly straight, the cable is guided along the track using sheaves – unpowered pulleys tha ...
