A contract has just been signed to deliver 600 gigawatthours a year of solar power between the US division of Spain’s giant Abengoa, and PG&E in California. Abengoa Solar hopes to succeed where BrightSource recently failed to overcome local NIMBY issues and Senator Feinstein, in its plan to site a 250 MW solar thermal plant in the made-for-solar Mojave Desert.

The long-awaited commercial deployment of the world’s most efficient solar technology looks like it will now be near Phoenix, in a 1.5-megawatt, 60-unit deployment of Stirling Energy Systems’ solar thermal collectors.

Announced late last week, the 60-dish Maricopa Solar project will be the first commercial-scale solar facility built using Stirling Energy Systems/Tessera Solar’s SunCatcher concentrating solar technology.

The SunCatcher consists of a solar concentrator in a dish structure that supports an array of curved glass mirrors. Iterations of the SunCatcher have been among the world’s most efficient machines for solar-to-grid electric conversion for twenty years, most recently breaking the record last year with the highest-ever conversion rate of 31.25%.

After less than a year of construction, the Sierra SunTower Plant that’s touted the first of its kind in the USA was finally officially launched by eSolar.

Located in Lancaster, California, this is the first eSolar concentrating solar thermal power plant with 24,000 mirrors instead of the company’s usual 12,000. The entire plant was built less than a year through the use of eSolar’s pre-fabricated components. Within that span of time, the plant’s heliostat mirrors have been utilized in various occasions, not to harness energy, but to greet the company CEO on his birthday and celebrate USA’s Independence Day. As was intended by Southern California Edison and eSolar, the 5-megawatt Sierra SunTower plant was connected to the grid this August 5 to power 4,000 homes in California’s Antelope Valley.

Exciting developments are occurring in solar PV (photovoltaic) power generation. New technologies are improving manufacturing processes. Thin-film and organic (plastic) films promise to reduce PV power cost. Solar “grid parity,” the time when solar power will cost the same as fossil fuel power, is coming soon.

It’s not diamonds.  Nor is it gold.  But it might be just as lucrative. European firms this time have their eyes on North African deserts as the location of a giant network of solar thermal plants to provide low-carbon energy for Europe.

Solar venture investments hit a three-year low in the second quarter, the Cleantech Group said Wednesday. According to Brian Fan, senior director of research for the group, solar startups in North America, Europe, China and India raised a total of only $113.8 million for the quarter, which is down 7 percent from $365.7 million in the first quarter and down 86 percent from $834.7 million in the year-ago quarter.

A new study from Greenpeace, the European Solar Thermal Agency, and the International Energy Agency’s SolarPACES Group has shown that concentrated solar power (CSP) could generate a quarter of the world’s energy needs by 2050–and create thousands of new jobs and prevent millions of tons of CO2 from being released.

Last week, we took a look at San Diego’s revolutionary solar plan, which will allow residents to pay for solar panels through property tax bills over a 20 year period. But don’t pack your bags for Southern California just yet. Annapolis, MD has a similar plan , dubbed the Annapolis (EZ) Energy Zone Program.

Albiasa Solar of Spain and the Arizona Department of Commerce are set to announce the building of a $1 billion solar-thermal power plant near Kingman, Arizona, next year, which will provide power for up to 50,000 homes when fully operational in 2013.

“The arrival of Albiasa Corp. is yet another big step toward establishing Arizona as a leader in the sustainable-industries sector.” - Arizona Governor Jan Brewer

Although some of the heavy hitters are still major players, 2008 has shown growth in renewable energy markets that had been weak previously. New players however are entering the renewable energy field, according to Clean Energy Trends 2009 report.

France

The vast majority of the electricity generated in France comes from its 59 nuclear reactors. It has not been considered a global leader in renewable energy, but France has taken some bold steps recently to support growth in this industry.

The government plans to have 23% of its electricity generated from renewable energy sources including hydroelectric by 2020. A feed-in tariff of 30 Euro cents for commercial buildings has been introduced to encourage solar energy growth.

France now exceeds Denmark in wind energy capacity after adding 950 MW in 2008. The country currently has 3,400 MW of wind power and plans to increase this to 25,000 MW by 2020.

National security is big business, and no one has benefited more than Lockheed Martin. Approximately $105 from each US taxpayer goes to Lockheed Martin. From defense contracts to supporting the invasion of Iraq, Lockheed Martin is in deep with US government’s priority of national security.
Recently, Lockheed Martin announced that increasing the development of renewable energy and energy efficiency technologies is just as important to national security as building fighter jets.
