Mission: Wolf – Resources

All the buildings at Mission: Wolf were built by volunteers and with donated materials. M:W is almost completely self-sufficient, using donations to pay for what they need, solar power on sunny days, and a propane generator when it is needed. Most ranchers in the area donate their livestock to the wolves when they die, giving [...]

Davidson County Solar Farm – Introduction

Davidson County Solar Farm will be the largest solar farm in the United States when completed in 2011. The 21.5-megawatt power station is located in the heart of North Carolina, near the community of Linwood. SunEdison will build the array of photovoltaic panels, and Duke Energy plans to buy all the output from the solar [...]

Climate change mitigation – Methods and means

] At the core of most proposals is the reduction of greenhouse gas emissions through reducing energy waste and switching to cleaner energy sources. Frequently discussed energy conservation methods include increasing the fuel efficiency of vehicles (often through hybrid, plug-in hybrid, and electric cars and improving conventional automobiles), individual-lifestyle changes and changing business practices. Newly [...]

Nuclear power – Environmental effects of nuclear power

Comparisons of life-cycle greenhouse gas emissions Comparisons of life cycle analysis (LCA) of carbon dioxide emissions show nuclear power as comparable to renewable energy sources. A conclusion that is disputed by others studies. Adapted from the Wikipedia article Nuclear power, under the G. N. U. Free Documentation License. Please also see http://en.wikipedia.org/wiki

Intermittent energy source – Introduction

Intermittent energy source is a term usually used to refer to some sources of renewable energy, such as wind and solar, (but not to geothermal generated electricity or hydroelectricity), because these sources of electric power generation may be uncontrollably variable or more intermittent than conventional power sources in normal operational conditions. Intermittency is a problem [...]

Thermal energy storage – Molten salt technology

Molten salt can be employed as a heat store to retain heat collected by a solar tower or solar trough so that it can be used to generate electricity in bad weather or at night. It was demonstrated in the Solar Two project from 1995-1999. The system is predicted to have an annual efficiency of [...]

Sustainable energy – Introduction

Sustainable energy is the provision of energy such that it meets the needs of the present without compromising the ability of future generations to meet their needs. Sustainable energy sources are most often regarded as including all renewable sources, such as plant matter, solar power, wind power, wave power, geothermal power and tidal power. It [...]

Shimizu Mega-City Pyramid – Advantages and disadvantages

Some advantages include that this city would have more rapid mobility, that the city will be better protected from tsunamis, and that it helps solve the high-prices for land in Tokyo. A major weakness in this project is that if one truss fails the whole structure and 750,000 people will crash to the sea. Ideally, [...]

Solar Ray – Introduction

”Solar Ray” is a 2001 album that was composed by Susumu Hirasawa. It features remixes from some of his older songs and albums, such as Philosopher’s Propeller and Aurora. These remixes are based upon his old band which disbanded in 1999, known as P-Model. Solar Ray’s songs are energetic and have an electropop feel, reminiscent [...]

Solar mirror – Photovoltaic augmentation

Photovoltaic cells (PV) which can convert solar radiation directly into electricity are quite expensive per unit area. Some types of PV cell, e.g. gallium arsenide, if cooled, are capable of converting efficiently up to 250 times as much radiation as is normally provided by simple exposure to direct sunlight. In tests done by Sewang Yoon [...]
