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 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 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. [...]
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, [...]
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 [...]
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 [...]

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 [...]
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 [...]
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 [...]
