German plant combines wind, biogas and hydrogen storage - The Hydrogen Journal. German plant combines wind, biogas and hydrogen storage Production, Oct 02 2009 (The Hydrogen Journal) - German wind power producer Enertrag is building a power plant in the state of Brandenburg which incorporates wind turbines, a biogas unit and hydrogen storage, according to press reports from news service UPI. The project has already got the attention of German chancellor Angela Merkel, who called the project "trend setting". It is located in Uckermark, the region she grew up in. There are three wind turbines with a total capacity of 6 mW; if their electricity cannot be immediately used, it is used to electrolyse water. The biogas plant produces biogas from maize supplied by 21 local farmers; this gas is then combined with the stored hydrogen to use in combined heat and power plants. It is due to start producing energy in early 2010.

Die Funktionsweise des Regenerativen Kombikraftwerks lässt sich in zwei Stufen unterteilen: die vorausschauende Steuerung und die Feinabstimmung. Das Kombikraftwerk vernetzt 36 Erneuerbare-Energien-Kraftwerke, die über ganz Deutschland verteilt sind. Elf Windanlagen, vier Biogas- und zwanzig Solaranlagen sowie ein Pumpspeicherkraftwerk sind durch eine zentrale Steuerungseinheit miteinander verbunden. Diese Kraftwerke sollen ein Zehntausendstel des deutschen Strombedarfs abdecken – dies entspricht dem Strombedarf von 12.000 Haushalten, also einer Stadt wie Schwäbisch Hall. Das Kombikraftwerk zeigt so im Kleinen, was auch im Großen möglich ist: eine jederzeitige Vollversorgung durch Erneuerbare Energien. Der tatsächliche Verlauf des Strombedarfs ist der zentrale Ausgangspunkt für alle Kraftwerksfunktionen. Abb. 1: Funktionsprinzip eines Regenerativen Kombikraftwerks, 1.

Reductions of emissions, and death rates from heart disease. Decline in emissions: Death rates from heart disease: The decline in air pollution in the USA actually began around 1970 when multiple changes took effect. These changes happened fast. 11-0307-Biodiesel-vs-Renewable_Final-_3_-JJY-formatting-FINAL. 20% renewable energy by 2020. Benefits of Renewable Energy Use.
Renewable energy — wind, solar, geothermal, hydroelectric, and biomass — provides substantial benefits for our climate, our health, and our economy: Each source of renewable energy has unique benefits and costs; this page explores the many benefits associated with these energy technologies. For more information on their potential impacts — including effective solutions to mitigate or avoid them entirely — see The Environmental Impacts of Renewable Energy Technologies. Little to No Global Warming Emissions Human activity is overloading our atmosphere with carbon dioxide and other global warming emissions, which trap heat, steadily drive up the planet’s temperature, and create significant and harmful impacts on our health, our environment, and our climate.

Could Biomass Technology Help Commercialize Biochar? Disadvantages of Renewable Energy – Drawbacks of Different Alternative Energy Sources | Green World Investor. Disadvantages of Nuclear Energy Disadvantages of Solar Energy Disadvantages of Hydro Energy 1) Environmental, Dislocation and Tribal Rights - Large Dam construction especially in populated areas leads to massive Tribal Displacement,Loss of Livelihood and Religious Infringement as potentially sacred Land is occupied by the Government.2) Wildlife and Fishes get Affected - The Fishes are the most affected species from Dam Construction as the normal flow of the river is completely changed form its river character to a lake one.Submergence of land also leads to ecological destruction of the habitat of land based wildlife.3) Earthquake Vulnerability – Large Dam Construction has been linked to increased propensity of Earthquakes.Massive Earthquakes in China and Uttarakhand in India were linked to the building of Massive Dams in these countries4) Siltation When water flows it has the ability to transport particles heavier than itself downstream.

In the shadows of wind and solar, another clean energy source is rapidly gaining steam and inciting equally lucrative profits. With about 10,500 MW installed to date, geothermal energy hasn't yet reached the scale of its cleantech cousins. Wind, for example, has ~142,000 MW of installed capacity worldwide; Solar has about 18,000 MW. But the wonders of geothermal energy are spreading far and wide. Its capacity is forecast to double in the next five years to ~21,000 MW. Our analysts have traveled the world over, dedicated to finding the best and most profitable investments in the global energy markets. And related stocks have been offering hefty returns to those willing to take a look at this unloved sector. Investing in Geothermal Energy Here's a chart that shows how geothermal has grown since the turn of the century. . . and how it's forecast to grow over the next decade: Everyone from Google to Middle Eastern oil sheiks are already lining up to get a piece of the imminent action.

Kleinwind Es gibt bis zum heutigen Tag keine eindeutige Definition für Kleinwindanlagen. Die gängigsten Definitionen werden hier kurz umrissen:Nach IEC-NORM 61400-2:2006, haben Kleinwindanlagen eine maximale Rotorfläche von 200 m², was einer Nennleistung von etwa 50 kW entspricht, bei einer elektrischen Spannung unterhalb von 1.000 V AC oder 1.500 V DC. Kleinwindenergieanlagen (KWEA) werden gemäß des Bundesverbands Windenergie (BWE) unterschieden in Mikrowindanlagen (bis 5 kW Nennleistung), Miniwindanlagen (von 5 kW bis 30 kW) sowie Mittelwindanlagen (von 30 bis 100 kW).Der Turm ist in der Regel nicht höher als 20 Meter, die durchschnittliche Leistung einer Kleinwindanlage liegt zwischen 5 und 10 kW.
Kleinwindanlagen sind insbesondere in Kombination mit anderen Erneuerbare-Energien-Technologien wie der PV gut geeignet für die elektrische Grundversorgung in netzfernen Regionen.
