Renewable Energy Corporation – Commercial Agreements

REC has entered into a significant long-term agreement for supply of mono-crystalline silicon wafer to Suniva, Inc. Under the agreement, REC will until 2013 deliver wafers worth more than USD 300 million. REC has also entered into a significant long-term agreement for supply of mono-crystalline silicon wafers to China Sunergy Co. Ltd. Under the agreement, [...]

Houston – Economy

Houston is recognized worldwide for its energy industry—particularly for oil and natural gas—as well as for biomedical research and aeronautics. Renewable energy sources—wind and solar—are also growing economic bases in Houston. The ship channel is also a large part of Houston’s economic base. Because of these strengths, Houston is designated as a beta world city [...]

Wind power in New Zealand – Coping with intermittency

Wind farms partner nicely with hydro plants on the same grid to create combined power plants, because hydro plants can be uprated with extra turbine units to provide highly dispatchable peak generating capacity above the average flows of their rivers, at lower cost than other peak power options. During periods of high wind and low [...]

Artificial photosynthesis – Potential Global Impact

Artificial photosynthesis is a renewable, carbon-neutral source of fuel, producing either hydrogen, or carbohydrates. This sets it apart from the other popular renewable energy sources — hydroelectric, solar photovoltaic, geothermal, and wind — which produce electricity directly, with no fuel intermediate. As such, artificial photosynthesis may become a very important source of fuel for transportation. [...]

Grid energy storage – Forms

Batteries Battery storage was used in the early days of direct-current electric power networks, and is appearing again. Battery systems connected to large solid-state converters have been used to stabilize power distribution networks. For example in Puerto Rico a system with a capacity of 20 megawatts for 15 minutes is used to stabilize the frequency [...]

EDF Energies Nouvelles – Introduction

EDF Energies Nouvelles is a French renewable energy corporation, half owned by French electric utility Électricité de France. It was formed in 2004 from its predecessor SIIF Energies and was floated on the Paris stock exchange in 2006. EDF En is primarily involved in the production of wind power in Europe and the United States, [...]

Photovoltaics – Applications

Power stations As of October 2009, the largest photovoltaic (PV) power plants in the world are the Olmedilla Photovoltaic Park (Spain, 60 MW), the Strasskirchen Solar Park (Germany, 54 MW), the Lieberose Photovoltaic Park (Germany, 53 MW), the Puertollano Photovoltaic Park (Spain, 50 MW), the Moura photovoltaic power station (Portugal, 46 MW), and the Waldpolenz [...]

Hybrid renewable energy system – Regulation

To get constant power supply, the output of the renewables may be connected to the rechargeable battery bank and then to the load. If the load is alternating current (AC), then an inverter is used to convert the direct current (DC) supply from the battery to the AC load. Consideration about voltage transition among modules [...]

Energy Policy Act of 2005 – Provisions

General provisions *Under an amendment in the American Recovery and Reinvestment Act of 2009, Section 406, authorizes loan guarantees for innovative technologies that avoid greenhouse gases, which might include advanced nuclear reactor designs, such as pebble bed modular reactors (PBMRs) as well as clean coal and renewable energy; *Increases the amount of biofuel (usually ethanol) [...]

Hydropower – Small scale hydropower

Small scale hydro or micro-hydro power has been increasingly used as renewable energy source, especially in remote areas where other power sources are not viable. Small scale hydro power systems can be installed in small rivers or streams with little or no discernible environmental effect on things such as fish migration. Most small scale hydro [...]

Design e2 – Episodes

;Season one # “The Green Apple”: sustainable design options for skyscrapers in New York city. # “Green for All”: incorporating cultural values into sustainable design for impoverished communities such as rural Mexico. # “The Green Machine”: the benefits of authoritarian leadership are demonstrated in the green projects of Chicago mayor Daley # “Gray to Green”: [...]

John Twidell – Introduction

John Twidell is Director of the AMSET Centre Ltd. and is a visiting lecturer at the Environmental Change Institute, University of Oxford, and the School of Aeronautics and Engineering, City University, London. He is Editor Emeritus of the academic journal ”Wind Engineering”. He co-edited the 2009 book ”Offshore Wind Power”. Professor Twidell previously held the [...]

Eastgate Renewable Energy Village – History

In 2002, the Weardale Task Force decided that Eastgate could provide a sustainable facility as part of the wider regeneration of Weardale. In 2004, an interim report found that the Eastgate Geothermal Exploration Borehole was capable of providing water at 26°C, potentially providing hot water and heating for the buildings on site. The planning application [...]

Renewable energy policy – Power generation

At least 60 countries, 37 developed countries and 23 developing countries, have some type of policy to promote renewable power generation. The most common policy is the feed-in law. By 2007, at least 37 countries and 9 states/provinces had adopted feed-in tariffs. Some 44 states, provinces, and countries have enacted renewable portfolio standards (RPS), also [...]

Sergey Brin – Other interests

Brin is working on other, more personal projects that reach beyond Google. For example, he and Page are trying to help solve the world’s energy and climate problems at Google’s philanthropic arm [http://www.google.org google.org]. He had Google invest in the alternative energy industry to find wider sources of renewable energy. They are trying to get [...]
