Alternative Technology
Alternative technology is a term used to refer to technologies that are more environmentally friendly than the functionally equivalent technologies dominant in current practice. The term was coined by Peter Harper, one of the founders of the Centre for Alternative Technology, North Wales (a.k.a. ''The Quarry''), in Undercurrents (magazine) in the 1970s. Alternative Technologies are created to be safer, cleaner, and overall more efficient. The goals of alternative technology are to decrease demand for critical elements by ensuring a secure supply of technology that is environmentally friendly, increased efficiency with lower costs, and with more common materials to avoid potential future materials crises. Alternative technologies use renewable energy sources such as solar power and wind energy. Some alternative technologies have in the past or may in the future become widely adopted, after which they might no longer be considered "alternative." For example, the use of wind turbines ...

Environmentally Friendly
Environment friendly processes, or environmental-friendly processes (also referred to as eco-friendly, nature-friendly, and green), are sustainability and marketing terms referring to goods and services, laws, guidelines and policies that claim reduced, minimal, or no harm upon ecosystems or the environment. Companies use these ambiguous terms to promote goods and services, sometimes with additional, more specific certifications, such as ecolabels. Their overuse can be referred to as greenwashing.Greenwashing Fact Sheet. 22 March 2001. Retrieved 14 November 2009. frocorpwatch.org/ref> To ensure the successful meeting of Sustainable Development Goals (SDGs) companies are advised to employ environmental friendly processes in their production. Specifically, Sustainable Development Goal 12 measures 11 targets and 13 indicators "to ensure sustainable consumption and production patterns". The International Organization for Standardization has developed ISO 14020 and ISO 14024 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Turbine
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. Hundreds of thousands of large turbines, in installations known as wind farms, now generate over 650 gigawatts of power, with 60 GW added each year. Wind turbines are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels. One study claimed that, wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and the most favorable social impacts" compared to photovoltaic, hydro, geothermal, coal and gas energy sources. Smaller wind turbines are used for applications such as battery charging for auxiliary power for boats or caravans, and to power traffic warning signs. Larger turbines can contribute to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Wind turbines are manufactured in a wide ...

Hydrogen Fuel Cell Vehicles
A hydrogen vehicle is a vehicle that uses hydrogen fuel Hydrogen fuel refers to hydrogen which is burned as fuel with oxygen. It is zero-carbon, provided that it is created in a process that does not involve carbon. It can be used in fuel cells or internal combustion engines (see HICEV). Regarding hydr ... for Power (physics), motive power. Hydrogen vehicles include hydrogen-fueled space rockets, as well as Hydrogen-powered ship, ships and Hydrogen-powered aircraft, aircraft. Power is generated by converting the chemical energy of hydrogen to mechanical energy, either by reacting hydrogen with oxygen in a fuel cell to power electric motors or, less commonly, by burning Hydrogen internal combustion engine vehicle, hydrogen in an internal combustion engine. , there are two models of hydrogen cars publicly available in select markets: the Toyota Mirai (2014–), which is the world's first mass-produced dedicated Fuel Cell Electric Vehicle, fuel cell electric vehicle (FCEV), and the ...
