By year’s end, regulators are expected to approve a host of solar energy projects in California that could eventually produce as much electricity as several nuclear plants. In an interview with Yale Environment 360, John Woolard, the CEO of the company that has begun (more…)

On August 4, Oakland-based BrightSource Energy Inc. got the thumbs up from the California Energy Commission to develop the Ivanpah Solar Energy Generating System (ISEGS), the world’s largest solar energy project.

The project has been fraught with difficulties since inception. In late 2009, (more…)

Each year, we come across a new set of discussions on the subject of Moore’s Law – the idea that the potency of technology doubles every two years. Intel co-founder Gordon Moore observed that the number of transistors that could be put onto an integrated circuit doubled with that regularity — and that this exponential growth persisted for an astonishingly long period of (more…)

An activist caravan to bring one of Jimmy Carter’s solar panels back to the White House symbolizes not only the time the U.S. has lost in developing new energy technologies – but also the urgent need for taking action on climate.

As I write this piece, we’re in the midst of a (biodiesel) road trip to Washington, D.C., (more…)

After years of delay, things are finally heating up for large-scale solar thermal power plants in California’s remote deserts. In the last month, a California Energy Commission (CEC) siting committee has recommended at least five solar plants for approval. Last week the first of these projects gained official go-ahead from the agency. The Beacon Solar Energy project (more…)

Despite recent legislative attacks that had one manufacturer threatening to pull up stakes, Arizona’s solar industry seems to be doing quite well. Global solar giant (and near stake-puller) Suntech Power remains committed to building a manufacturing plant in Goodyear, and recently, Governor Jan Brewer, Mayor Lyn Truitt and industry representatives announced the arrival of a (more…)

Solar Energy (both photovoltaic and solar hot water, aka solar thermal) are great resources to have at your disposal. In the case of photovoltaic, you can substitute the power from your utility grid by harnessing the sun’s power and converting the sun’s rays into electricity. With rising electricity prices, photovoltaics (aka solar electric) is a great hedge against ever expanding utility bills. The photovoltaic industry is growing by leaps and bounds. You may want to get into the action. (more…)

BrightSource Energy, Inc., developer of utility-scale solar thermal power plants, has raised an additional $150 million in its most recent equity financing. The Series D round brings BrightSource’s total equity financing to more than $300 million and positions the company for significant growth.

New investors including Alstom and the California State Teachers Retirement System (CalSTRS) joined existing investors in this round, led by VantagePoint Venture Partners, Morgan Stanley and Draper Fisher Jurvetson.

The additional financing will be used to support BrightSource’s 2,610 megawatts in contracts with Pacific Gas and Electric Company (PG&E) and Southern California Edison to build 14 solar power plants in the US southwest by 2016. The funds will also be used by BrightSource to further its international expansion plans.

California recently approved the decision of a state-wide solar heating program consisting of almost $360 million financial incentives and market development funding by 2018. This initiative will soon be followed by rest of the country that lagged behind the world in installing solar thermal systems.

Global statistics show that the solar thermal industry is taking large steps in fulfilling heating and cooling demand in the world. Most of the countries around the world have adopted incentive programs for both solar water heating and space heating. Whereas in some countries, solar thermal systems have been widely utilized for so many years even without incentives.

The most important decision criteria for a household to install a solar thermal system is basically the payback times of their investment. The main driving factors of the investment payback time are the total cost of the systems and the cost of alternatives heating systems. (more…)

HelioFocus Ltd., an Israel-based solar thermal systems start-up, has raised more than $10 million from China’s Zhejiang Sanhua Co. and existing investor IC Green Energy.

HelioFocus announced the investment last week at the Weizmann Institute of Science in Rehovot, Israel, where HelioFocus is developing its solar thermal technology to boost electricity production of existing power plants.

HelioFocus CEO Ory Zik said Sanhua, the Chinese maker of appliance components whose stock is traded on the Shenzhen stock exchange, would be not just a financial investor in the company, but will also produce some solar thermal components.
