Читаем Электрические Схемы 1 часть. 1 – Новый LEAF: икона концепции Nissan Intelligent Mobility С началом производства первого поколения LEAF в 2010 году Nissan начал революцию в мире автомобилестроения, демонстрируя, что электромобиль с нулевым уровнем выбросов вредных веществ способен принести огромную выгоду покупателям и обществу в целом и навсегда изменить автомобилестроение как отрасль.

Сочетание нулевой токсичности (за пользование электромобилями водители во многих городах мира пользуются сниженными налоговыми ставками, получают более удобные варианты парковки и право на бесплатный проезд по платным дорогам) с низкими расходами на содержание, почти бесшумным двигателем и изяществом премиум-класса оказалось весьма привлекательным для будущих владельцев электромобилей. После запуска производства электромобилей инфраструктура зарядки расширилась, что сделало владение электромобилем еще более удобным и привлекательным.

An intermittent energy source is any source of energy that is not continuously available due to some factor outside direct control.

Intermittent energy source

The intermittent source may be quite predictable, for example, tidal power, but cannot be dispatched to meet the demand of a power system. Effective use of intermittent sources in an electric power grid usually relies on using the intermittent sources to displace fuel that would otherwise be consumed by non-renewable power stations, or by storing energy in the form of renewable pumped storage, compressed air or ice, for use when needed, or as electrode heating for district heating schemes. Wind & Solar. Environmental concerns with electricity generation. The environmental impact of electricity generation is significant because modern society uses large amounts of electrical power.

5 Myths About Renewable Energy"


Biomass. Waste to Energy. Methane. Carbon cycle. This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, and oceans in billions of tons of carbon per year.

Carbon cycle

Yellow numbers are natural fluxes, red are human contributions in billions of tons of carbon per year. White numbers indicate stored carbon. The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Along with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events that are key to making the Earth capable of sustaining life; it describes the movement of carbon as it is recycled and reused throughout the biosphere. The global carbon budget is the balance of the exchanges (incomes and losses) of carbon between the carbon reservoirs or between one specific loop (e.g., atmosphere ↔ biosphere) of the carbon cycle. Relevance for the global climate[edit]

Calculating. Magneto Electrics. Main Page - PESWiki. Smart grid. Renewable Energy in situ. Vehicle. Cost of electricity by source. Cost factors[edit] While calculating costs, several internal cost factors have to be considered.[2] (Note the use of "costs," which is not the actual selling price, since this can be affected by a variety of factors such as subsidies and taxes): Capital costs (including waste disposal and decommissioning costs for nuclear energy) - tend to be low for fossil fuel power stations; high for wind turbines, solar PV; very high for waste to energy, wave and tidal, solar thermal, and nuclear.Fuel costs - high for fossil fuel and biomass sources, low for nuclear, and zero for many renewables.Factors such as the costs of waste (and associated issues) and different insurance costs are not included in the following: Works power, own use or parasitic load - that is, the portion of generated power actually used to run the stations pumps and fans has to be allowed for.

Blog » Clarity on the true cost of electricity

Most of us know oil prices go up and down – and are currently at record highs – which in turn affects the power price. And we know that not only to the costs of importing such fuels change constantly, they also – unlike renewables – produce carbon, which has to be paid for. But while more and more people are saying onshore wind energy is at “competitive” price levels, others still insist that renewables are expensive and impractical. In order to clear up the issue , EWEA has developed an online tool that instantly calculates electricity costs, including any fuel and carbon risks, for five different technologies – gas, coal, nuclear, onshore and offshore wind.

The users are free to type in their own assumptions on, for example, coal and gas prices, future carbon costs, capital cost and availability. Try the tool for yourself:

Carbon Sequestration (Storing It) Dirty Energy. Tar Sands. Renewable Energy Used to Make Drinking Water From Air Humidity – Blue Living Ideas. Availability Published on June 18th, 2009 | by Jennifer Lance Scientists have discovered a way to make drinking water from the air’s humidity, even in arid regions. The system completely uses renewable energy and could provide water for many applications.

Renewable Energy Used to Make Drinking Water From Air Humidity – Blue Living Ideas

Models have been built and tested in laboratories at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart. Image by hamed saber Scientists can make drinking water from desert air. Even in areas where there is no surface water or plant life, there is still moisture in the air. The process uses thermal solar collectors and photovoltaic cells, so it can function where there’s no electricity, such as in deserts. Removing the humidity from the air to make drinking water is a unique solution, but I wonder what the meteorological consequences would be to the environment. Would it affect precipitation in non-arid regions? About the Author. How Information Can Save Energy. In 2007, an astounding 2.2 million residents of Sydney, Australia turned off their lights in the first ever Earth Hour organized by the World Wildlife Fund (WWF).

How Information Can Save Energy

Over time, more cities and homes have come to participate in this annual event, conceived by the WWF to increase awareness about climate change and encourage energy efficiency. The Earth Hour is a laudable event to educate ordinary people on energy use. There is still, however, a need to increase information dissemination efforts from merely annual events to a regular part of daily life. In fact, experts say that making energy information as available and accessible as possible will help consumers make informed decisions and thus minimize the risk of irresponsible energy use. This was evidenced by an experimental study on residential electricity consumers conducted by the US National Bureau of Economic Research. Humphrey Kariuki Ndegwa is a recognized leader in the energy and oil sector.
