Solar electricity production in California falls into two categories ... solar thermal, using the concentrated heat of sunlight to heat a fluid to make steam to turn a traditional turbine and generator making electricity, and solar photovoltaic (PV), the direct conversion of sunlight into electricity. Additionally, the heat from the sun is used in solar thermal systems for hot water in homes and businesses and in heating swimming pools. Most electricity from PV is not counted into the total electricity production of the utility companies as the solar panels are mounted on individual homes or b... More →

Eric Worrall blogs that the WUWT blog recently reported how California had abandoned rooftop solar, by excluding them from generous renewable credit schemes. California has now intensified its attack on renewable energy consumers, by increasing fees for customers who switch to renewable energy schemes.

The California Public Utilities Commission voted Thursday to allow a nearly 100 percent price increase on exit fees for customers leaving Pacific Gas and Electric Co. for green energy programs like CleanPowerSF and Marin Clean Energy, which will make those and similar programs more ex... More →

This article is a post-mortem on a project initiated by Google, a master of innovation with impeccable green credentials, the goal of which was to scope out an innovative renewable energy system (solar) that could compete economically with coal and other fossil fuels and which could be deployed quickly enough to stave off the worst impacts of climate change. They did not consider nuclear.

Work on the project, which Google named RE<C, aka Renewable Energy Cheaper than Coal, continued from 2007 to 2011, a period over which Google invested large sums of money in renewable energy pr... More →

Christopher Helman asks if it make sense for Apple to lock in electricity prices at twice the going rate. You probably heard the news already - Apple Computer is teaming up with First Solar to invest 850 million dollars on a 2,900-acre, 280 megawatt solar farm in Monterey County, Calif. Everyone other than the owls, lizards and San Joaquin kit foxes that live on the land seem to think this is a really great deal, an example of the biggest company stepping up and doing something constructive about climate change or whatever. Helman was curious about how good or bad a deal this is for Apple shar... More →

Henning Gloystein and Aaron Sheldrick claim that one by one, Japan is turning off the lights at the giant oil-fired power plants that propelled it to the ranks of the top industrialized nations. With nuclear power in the doldrums after the Fukushima disaster, it is solar energy that is becoming the alternative, but this is a gross mi-representation.

Solar power is set to become profitable in Japan as early as this quarter, according to the Japan Renewable Energy Foundation (JREF), freeing it from the need for government subsidies and making it the last of the G7 economies where the ... More →

The world now consumes ~ 14 terawatts of commercial thermal power (14 TWt). The surface of our Moon independably intercepts 13,000 TWs of solar power. This Lunar Solar Power is converted on the Moon into to electric power and then to beams of ~2.5 GHz microwaves to which Earth's atmosphere is transparent. Beam receivers on Earth convert the low-intensity microwaves (< 20% of sunlight) to commercial electric power. A given receiver outputs ~200 W/m2 of load following electric power to its regional electric grid. LSP facilities are made from the local lunar materials by small manufacturing un... More →

Joe Ryan and Brian Eckhouse, of Bloomberg, report that for all the upbeat forecasts about the growth of solar power, this is a punishing year for the industry. And it will not improve anytime soon. For example, SunEdison Inc., the biggest solar energy company, is bankrupt. Yingli Green Energy Holding Co., once the top solar panel maker, warned it may be inching toward default. And SolarCity Corp., the largest U.S. rooftop installer, plunged as much as 27% after scaling back its installation forecast for the third time in seven months.

They are not alone. A Bloomberg index of 20 maj... More →

Donn reports that recent activity on the Internet has tried to turn this fact on its head. While it is not unexpected that supporters of PV - Photo-Voltaic - rooftop solar would attempt to turn the facts upside down, the addition of a Tea Party activist to the group supporting PV rooftop solar makes news. Debbie Dooley, reportedly a founding member of the national Tea Party, and a member of Conservatives for Energy, supports the Florida ballot initiative called Floridians for Solar Choice.

The Floridians for Solar Choice web site says that giving Floridians should have a vote and a ... More →

Donn reports that his previous article - Part 1 - showed how people are sponging off the grid with PV rooftop solar systems. The claim is frequently made that fossil fuels get more subsidies than do renewables. Like so many claims made by advocates for wind and solar, this is also bogus. Actually, the subsidies received by renewables have been far greater in recent years than those received by fossil fuels.

Perhaps the biggest untruth with respect to energy is that fossil fuels receive huge subsidies, while wind and solar receive few if any subsidies. A report providing data on sub... More →

The Solar Alliance blogs that solar energy is a clean, abundant and renewable energy and the U.S. has plentiful supplies. With current technology there are several ways to tap this energy for both light (PV) and heat (CSP) and for private and commercial use.

Three simple ways to harness solar energy ...

2. Concentrating solar power, or thermal energy (CSP), which uses the Sun heat to provide energy to electric turbines which produces electricity and is dispersed to consumers.

By David R. Criswell, Ph.D., University of Houston.
Rectennas located on Earth between 60º N and 60º S
can receive power directly from the moon approx. 8 hours a day. Power could be received anywhere on Earth via a fleet of relay satellites in high-inclination, eccentric orbits around Earth (Figure 2). A given relay satellite receives a power beam from the moon and retransmits multiple beams to several rectennas on Earth required by an alternative operation. This enables the region around each rectenna to receive power 24 hours a day. The relay satellites would require less... More →

William Pentland reports that the Tesla new storage batteries will not put your local utility out of business anytime soon. That was the take away from the Elon Musk keynote address yesterday at Edison Electric Institute annual convention in New Orleans.

Industrial-scale batteries designed for peak shaving are projected to account for upwards of 90% of all Tesla battery sales, according to Musk. Rather than hurting utilities, this should help them, according to Musk. Batteries can be used to shift load, reducing peak demand.

Of course, I never worried about the Tesla bat... More →

While energy sources like sunlight and wind are free and naturally replenished, converting them into large quantities of electricity requires vast amounts of natural resources — most notably, land. Even a cursory look at these costs exposes the deep contradictions in the renewable energy movement.

Dr. Conca reports that the largest solar energy facility in the world is already irrelevant and has cost a lot more to construct than any other form of energy. The Ivanpah Solar Electric Generating System is a 5-square-mile, 392 MW array that cost 2.2 billion US dollars. It is located in the Mojave Desert, where the Sun always shines, and is supposed to produce a billion kWhs per year for 25 years. But there is a problem - the Sun does not seem to be cooperating. A spokesman for NRG Energy blamed the weather, saying the Sun did not perform as predicted. Instead of a billion kWhs of electricity... More →

Patrick Caughill reports that solar power has been making some impressive strides in 2016. The first three quarters of this year have already seen more new installations of solar panels than the entirety of 2015. A report by GreenTech Media shows that in the third quarter (Q3) of this year alone, enough solar panels to generate 4,143 MW of electricity were installed in the U.S. Q3 of 2016 has seen a 191% rise in installations from the same quarter last year, making it the new record holder for new solar power installations in the country.

Dr. Conca reports that the Brattle Group, with support from the Edison Electric Institute, just released a study concluding that utility-scale solar photovoltaic (PV) systems in the U.S. are more cost effective than residential-scale (rooftop) PV systems in achieving the economic and policy benefits we all expect to come from the widespread use of solar energy. But it may not be that simple and depends on what goal you have as a user.

The study was commissioned by First Solar, one of the largest solar companies in America. Titled Comparative Generation Costs of Utility-Scale and Res... More →
