Renewable Energy Group began in 1996 as the biodiesel division of West Central Cooperative with the construction of a plant in . In 2006, the company separated from West Central and moved its headquarters to Ames. In 2013, the company acquired -based biofuels company Syntroleum Corporation amid that company's struggles for profitability. In 2015 it acquired the assets of -based.

[pdf] You have the option to purchase renewable electricity, either directly from your power supplier, from an independent clean power generator, or thro. .
Some power companies provide an optional service, called green pricing, that allows customers to pay a small premium in exchange for electricity generated from clean, renewable. .
In some parts of the country, you can choose not only how your electricity is generated, but also who generates it. Just as the long-distance telephone industry was restructured,. .
Buying green certificates allows you to contribute to the generation of clean, renewable power even if you can't buy clean power from.
[pdf] Modules connected in seriesform strings, and strings can be connected in parallel to an inverter. The electrical current through all the modules of a string must be the same. By contrast, the voltage of parallel strings must be the same. As we saw in the last section, a shaded module in a string can bring down the power. .
Bypass diodes are devices within a module that allow the electrical current to “skip over” shaded regions of the solar module. By using bypass. .
MLPEsare devices that are attached to individual modules to increase performance under shaded conditions (though there are other.
[pdf] The early development of solar technologies starting in the 1860s was driven by an expectation that coal would soon become scarce, such as experiments by . installed the world's first rooftop photovoltaic solar array, using 1%-efficient cells, on a New York City roof in 1884. However, development of solar technologies stagnated in the early 20th centu.
[pdf] The typical reference system-of-systems involves a significant number (several thousand multi-gigawatt systems to service all or a significant portion of Earth's energy requirements) of individual satellites in GEO. The typical reference design for the individual satellite is in the 1-10 GW range and usually involves planar or concentrated solar photovoltaics (PV) as the energy collector / conversion. The most typical transmission designs are in the 1–10 GHz (2.45 or 5.8 GHz) RF b.
