Which Is Cheaper? Nuclear or Solar

A new study reveals that nuclear energy and other traditional energy supplies like fossil fuels cost are and will continue to rise and not likely ever go back down. Meanwhile, renewable energy has achieved a “downward cost curve” over the last decade, and they are likely to continue to fall in price.

Leading the Charge to Make Solar as Cheap as Conventional Electricity

Leading the Charge to Make Solar as Cheap as Conventional Electricity

Suntech CEO, Zhengrong Shi, a prime mover in helping to turn China into a global force in photovoltaic technology, has been a major influence in bringing China’s solar PV cost structure down and making China a powerhouse in photovoltaic technology–and became a billionaire in the process. Shi’s ambition is to make solar power as cheap as conventional electricity.

Community Solar Heats Up

Community Solar Heats Up

Residential solar installations are fairly expensive propositions, making it more difficult for people to participate in this renewable energy resource. But now a relatively new concept—community solar—is seeing the light of day. Despite some financial, legal and technology barriers, a handful of utilities in cities like St. George, UT, and Seattle, WA, have come together for community solar, paving the way for more to follow. Private industry is also stepping in, helping the market to heat up more quickly.

High Efficiency Solar Cells Can Be Made At a Much Lower Cost

High Efficiency Solar Cells Can Be Made At a Much Lower Cost

Scientists at the California Institute of Technology have developed a new type of solar cell that comprise of arrays of thin silicon wires embedded in polymer substrate. The unique optical interactions between these wires provide the cells with an enhanced light absorption capability and improved internal quantum efficiency over conventional solar cells. These new cells are much cheaper to produce on account of the very low amounts of silicon needed to build them. The superior structural flexibility possessed by the silicon wire array solar cells is expected to further reduce their production cost since they can be produced using a lower-cost process.

Five Promising Thin Film Solar Startups

Five Promising Thin Film Solar Startups

It is a rough time to be a startup in the Solar Photovoltaic sector. The financial crisis and deep recession has not only dried up capital, but has also hit demand for solar panels, which has lead to a global supply glut and a price collapse. In this very difficult environment startups must compete with much larger established global suppliers that have factories of hundreds of megawatts each, an established customer base and well developed brand names and sales channels. In this post we look at five promising CIGS thin film Solar PV startups based in the US and try to catalog their unique strengths and accomplishments.

Six US Based Solar PV Equipment Manufacturers to Watch

Six US Based Solar PV Equipment Manufacturers to Watch

The manufacturers of the equipment and production lines that are needed to produce solar cells and modules are an important segment of the overall value chain in the solar PV sector as a whole. These companies are making a wide variety of equipment that finds use in the manufacture of solar cells, ranging from tradition semi-conductor manufacturing equipment that has grown out of the computer semi-conductor industry, to more exotic things like specialized inkjet printers and lasers. Who are these US based solar photovoltaic equipment manufacturers and how are they fairing in the global recession of 2009?

Four Big Established US Solar PV Companies You Should Know About

Four Big Established US Solar PV Companies You Should Know About

In this survey we are looking at the large US headquartered solar PV manufacturers with a view to examine how they are doing in this difficult economic climate. As basically anyone knows, who has not been cloistered away meditating in some cave, 2009 has been a very tough year for pretty much everyone.

PG&E Inks Out of this World Deal for Power [UPDATED]

California’s biggest utility PG&E is seeking approval from state regulators for a power purchase agreement with Solaren Corp., a Southern California company that has contracted to deliver 200 megawatts of clean, renewable power over a 15 year period, beginning in 2016. Power from out of this world, that is. Solaren says it plans to generate the power using solar panels in earth orbit, then convert it to radio frequency energy for transmission to a receiving station in Fresno County. From there, the energy will be converted to electricity and fed into PG&E’s power grid. UPDATE: The California Public Utilities Commission gave its approval yesterday to the project giving it the green light to proceed.

$750M in New Funding for Renewable Energy Projects from the American Recovery and Reinvestment Act

U.S. Energy Secretary Steven Chu announced in Washington that the Department of Energy (DOE) will provide up to $750 million in new funding from the American Recovery and Reinvestment Act to help accelerate the development of renewable energy generation projects. This funding will be targeted to cover the cost of loan guarantees for renewable energy projects and could support as much as $4 to 8 billion in lending to eligible projects, and the Department will invite private sector participation to accelerate the financing of these renewable energy projects.
