  • Solar Photovoltaic

    slolarSolar energy, radiant light and heat from the sun, is harnessed using a range of ever-evolving technologies such as solar heating, solar photovoltaics, solar thermal electricity, solar architecture and artificial photosynthesis. Read More 

  • Climate Change

    climateClimate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions, or in the distribution of weather around the average conditions (i.e., more or fewer extreme weather events). Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have also been identified as significant causes of recent climate change, often referred to as "global warming". Read More

  • Off-Grid Electrification

    offgridMicrogeneration 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. It differs from micropower in that it is principally concerned with fixed power plants rather than for use with mobile devices. Read More

  • Distributed Generation

    onsiteDistributed generation, also called on-site generation, dispersed generation, embedded generation, decentralized generation, decentralized energy, distributed energy or district energy,[1] generates electricity from many small energy sources. Most countries generate electricity in large centralized facilities, such as fossil fuel (coal, gas powered), nuclear, large solar power plants or hydropower plants. These plants have excellent economies of scale, but usually transmit electricity long distances and can negatively affect the environment. Distributed generation allows collection of energy from many sources and may give lower environmental impacts and improved security of supply. Read More

  • Rural Electrification

    ruralRural electrification is the process of bringing electrical power to rural and remote areas. Electricity is used not only for lighting and household purposes, but it also allows for mechanization of many farming operations, such as threshing, milking, and hoisting grain for storage. In areas facing labor shortages, this allows for greater productivity at reduced cost. Read More

    Energy consumption is the consumption of energy or power. Read more

  • Renewable Energy

    offgridRenewable energy is a socially and politically defined category of energy sources. Renewable energy is generally defined as energy that comes from resources which are continually replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat. Read More

  • Renewable Energy Development

    slolarRenewable 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. Read More

  • Greenhouse Gasses

    Greenhouse_EffectA greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.[1] The primary greenhouse gases in the Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone.

  • Energy Conservation

    offgridEnergy conservation refers to reducing energy through using less of an energy service. Energy conservation differs from efficient energy use, which refers to using less energy for a constant service. For example, driving less is an example of energy conservation. Driving the same amount with a higher mileage vehicle is an example of energy efficiency. Energy conservation and efficiency are both energy reduction techniques. Read More

  • Watt

    he watt (symbol: W) is a derived unit of power in the International System of Units (SI), named after the Scottish engineer James Watt (1736–1819). The unit, defined as one joule per second, measures the rate of energy conversion or transfer. Read More

  • Watthour

    The kilowatt hour, or kilowatt-hour, (symbol kW·h, kW h or kWh) is a unit of energy equal to 1000 watt-hours or 3.6 megajoules.[1][2] For constant power, energy in watt-hours is the product of power in watts and time in hours. The kilowatt-hour is most commonly known as a billing unit for energy delivered to consumers by electric utilities. Read More

  • Ampere

    The ampere (SI unit symbol: A; SI dimension symbol: I), often shortened to amp,[1] is the SI unit of electric current[2][3] (quantity symbol: I, i)[4] and is one of the seven[5] SI base units. It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electrodynamics. Read More

  • Ampere-hour

    An ampere-hour or amp-hour (symbol A·h, A h, Ah) is a unit of electric charge, with sub-units milliampere-hour (mA·h or mAh; often used in rechargeable and disposable battery specifications) and milliampere-second (mA·s). One ampere-hour is equal to 3600 coulomb. Read More

  • Volt

    The volt (symbol: V) is the SI derived unit for electric potential (voltage), electric potential difference, and electromotive force.[1] The volt is named in honour of the Italian physicist Alessandro Volta (1745–1827), who invented the voltaic pile, possibly the first chemical battery.

    batterisAn electric battery is a device consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy. Each battery consists of a negative electrode material, a positive electrode material, an electrolyte that allows ions to move between the electrodes, and terminals that allow current to flow out of the battery to perform work.

Una volta lo scienziato scoperto la regione sensibile all’interno della vagina, situata sul muro anteriore a una distanza di circa 7 cm dall’ingresso. Oggi questa zona è conosciuta come un punto G, farmaciaitalia negli anni ’40 il ricercatore non ha nemmeno dato il suo nome, scrivendo semplicemente: “La principale zona erotica è forse ancora più importante del clitoride”. La maggior parte di tutto Graphenberg ha sorpreso che, quando stimolando questa zona, una donna non ha semplicemente raggiunto l’orgasmo, ma anche eiaculato.
