  • The Grid vs. Rooftop Solar

    The development of solar micro-grids and mini-grids in the remotest parts of Australia seems to be a rational step in the right direction economically. However, network operators all over the world are still in doubt when it comes to the vast population in urban areas adopting similar methods. The question lies with the homeowner choosing to buy the necessary power generating equipment ...

  • Solar Power 2011 - Solar PV Breaks Records in 2010

    Solar photovoltaic (PV) companies manufactured a record 24,000 megawatts of PV cells worldwide in 2010, more than doubling their 2009 output. Annual PV production has grown nearly 100-fold since 2000, when just 277 megawatts of cells were made.  Newly installed PV also set a record in 2010, as 16,600 megawatts were installed in more than 100 countries.  This brought the total worldwide ...

  • World Solar Power Topped 100,000 Megawatts in 2012

    The world installed 31,100 megawatts of solar photovoltaics (PV) in 2012—an all-time annual high that pushed global PV capacity above 100,000 megawatts. There is now enough PV operating to meet the household electricity needs of nearly 70 million people at the European level of use. While PV production has become increasingly concentrated in one country—China—the number of ...

  • Near Term Lower Cost Solar Electric Power for US Commercial Customers

    Market Opportunities The first market for PV electric power panels was for space satellites. While the single crystal cells used in these panels made these panels very expensive, this was unimportant for that market. That market emphasized reliability, not cost. As these panels came down to earth for off-grid remote applications, again the emphasis was on reliability and low maintenance, not ...

  • A brighter future for solar in Texas

    I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that. - Thomas Edison, in conversation with Henry Ford and Harvey Firestone, 1931 According to the State Energy Conservation Office (SECO), Texas has the greatest solar energy potential of any state in the country. “If photovoltaic (PV) systems operating ...

  • Avoiding the Power Grid with Renewable Energy

    For approximately one hundred years, thriving countries have been dependent on only one form of distributing power; electricity sent over large transmission grids from plants generating electricity, to customers in businesses, homes, and factories.  Generators extract energy from rooftop solar panels, garbage, and sewage, which replace or assist coal, nuclear, and natural gas plants. A ...

  • Wind power growth in the US

    Last year was a banner year for renewable energy in the United States, especially for the wind industry. As the recent REN21 Renewables 2007 Global Status Report highlights, the industry broke all past global records, installing 5,244 megawatts (MW) of new wind energy capacity in 2007, or 30 percent of all new U.S. capacity added. This brings the cumulative national total close to 17,000 ...

  • The Emerging Power of Microgrids

    Over many decades, the centralized power grid — a one-way flow of electricity, generated by large, remote power plants and distributed over miles of transmission lines to homes and businesses — succeeded in delivering electricity across continents to billions. But in recent years the system’s shortcomings have become increasingly ...

  • Solar`s Time to Rise and Shine.

    Photovoltaic efficiency records are being shattered, thanks to recent advances in materials science. Last month, a researcher at the National Renewable Energy Laboratory in Golden, Colo., loaded a postage stamp–sized solar cell onto a tray and placed it under a high-intensity pulse solar simulator. The simulator flashed a 2.5 millisecond pulse of light, and 19 mirrors reflected the ...

  • How to grow a solar energy garden

    Getting energy from the sun is a great idea. However, installing solar panels house-by-house is slow, costly and cumbersome, and downright inefficient if the goal is to bring solar to the masses. This problem troubled Paul Spencer after he built his own uber-efficient, custom solar home near Aspen, Colorado in 2004.  The engineer and serial entrepreneur wondered how he could replicate his ...

  • Will natural gas dim solar’s shine?

  • Renewable, local power options expand

    It makes no economic sense to run more than one set of wires from electric power generators to homes and businesses. That’s why consumers haven’t had a choice about the source of their electric power – whether it be an investor-owned utility (IOU), municipal utility or electric cooperative. Enabling consumers to choose between competing energy providers is a paradigm shift, and ...
