It recently became official news that solar power is cheaper than electricity from gas-fired power plants. I asked myself: if natural gas is below grid parity and solar is cheaper than gas, doesn’t that mean that solar is also below Read more…


Gemasolar is a 17-MW solar power tower plant with 15 hours of molten salt energy storage. Yes, a solar power plant that will deliver solar electricity round-the-clock: at 10 pm., at 1 am., and at 4 am. Gemasolar has a capacity factor of 75% and is scheduled to open in about two months.


In 1912 Egypt built the first commercial solar power plant in the world. At a time when Egypt was the largest producer of cotton in the world, American inventor and entrepreneur Frank Shuman engineered, raised financing for, and built a Read more…


The future of energy is all about abundant, cheap, and clean power. Over the last few months of 2010 the U.S. Department of Interior’s Bureau of Land Management (BLM) and the California Energy Commission (CEC) approved 10 large-scale Concentrating Solar Read more…


Imagine that every car in America was an Electric Vehicle (EV) powered by a electric battery like the Tesla’s (Nasdaq: TSLA) Roadster.  Imagine also that each and every car was powered with solar energy. Here’s a question: what amount of Read more…


Imagine a world where you can buy electricity from your choice of vendor (not the utility) at prices that can be negotiated with the vendor. Kind of like shopping at eBay or Amazon. Want to buy a week’s worth (1,000 Read more…


As building integrated photovoltaic technology, or BIPV, follows the downward technology cost curve, solar tiles, solar bricks, and solar windows will approach (maybe beat) the cost of traditional tiles, bricks, and windows. BIPV homes will not just sit there: they will be personal power plants. The energy they generate will be essentially free.
