Solar Desalination Could be a Game Changer for California Farms

Let’s be clear from the outset: I’m no fan of conventional desalination. The idea of using climate-altering fossil fuels to drive an energy-intensive de-salting process that threatens coastal environments in order to produce drinking water that, in most cases, could be secured more cheaply through conservation and efficiency improvements, simply fails to pass the bar of economically sensible, environmentally sound solutions to our water problems. But now desalination of a very different stripe is under way – not by the sea, but in California’s drought-stricken Central Valley farming region. The project is turning salty, contaminated agricultural drainage into fresh water that can be re-used to irrigate crops. Powered not by fossil fuels, but by the sun, the technology has the potential to shift the way water is used and managed in parts of the west, where agriculture accounts for 70-80 percent of water use. Developed by a San Francisco-based […]

Israel signs deal for $1.1 billion thermo-solar power plant

Israel signed a deal to build a 4 billion shekel ($1.05 billion) thermo-solar power plant in the country’s south, aimed at boosting electricity production from renewable energy sources, the Finance Ministry said on Sunday. The 121 megawatt plant, which will also be able to store electricity, will be built by a consortium of Israel’s Shikun & Binui and Spain’s Abengoa in Ashalim in Israel’s southern Negev desert near another solar plant. The plant, to be built under a build, operate and transfer program, is expected to come online in the first half of 2018, the ministry said. Both plants – along with a planned photovoltaic power plant nearby – will provide 2 percent of total electricity production in Israel, which has a target of 10 percent coming from renewable sources by 2020. They will be financed by the European Investment Bank and the U.S. Overseas Private Investment Corp. The […]

German Green Power Forces Neighbors to Bolster Blackout Defenses

Chart: German Wind Power Peaks Germany’s drive to harness wind and solar power is producing so much electricity that it’s spilling over into neighbors’ grids and increasing the threat of blackouts. Poland and the Czech Republic are spending $180 million on equipment to protect their systems from German power surges, while Austria is curbing some trading to prevent regional networks from collapsing. On a windy day, the overflow east can exceed the output from four atomic reactors. Germany’s fivefold increase in green energy in the past decade has outpaced investment in power lines to move it across the country. Electricity is looping through Poland and the Czech Republic to reach southern Germany, where supply is constrained as Chancellor Angela Merkel shuts nuclear plants after the 2011 Fukushima disaster in Japan. The disruptions show the limits to the European Commission’s vision of a single power market. “A huge accumulation of […]

Israeli Gas Boon Blocks Out Solar Industry Hopes

TARABIN, Israel—The residents of this village in the Negev desert have everything they need to build a solar-panel field: construction permits and loans, a contract with a company to build the field, and plenty of sun. But Tarabin village doesn’t yet have permission from the government to sell its solar power to the national grid—a crucial prerequisite for making the project economical. Dozens of communities across Israel are in the same situation, and executives and backers of the solar industry here are blaming an unlikely culprit: natural gas. Two big offshore gas finds in 2009 and 2010 shifted priorities and resources away from solar projects, they say. Shortly after, the government stopped approving the hookup of new solar projects to the grid. That has left villages like Tarabin waiting. It has also devastated the small, once-promising solar-power industry here. The proposed site for the field outside of town here […]

Rapid Expansion of Utility-Scale Solar in China

Solar is taking over the Gobi Desert in China’s Gansu province. China is a difficult solar market to track from the outside. Government subsidies are opaque and bureaucratic, interconnection problems run rampant, and non-Chinese businesses often have a hard time getting into the country. There’s no doubt that the Chinese PV market is growing at unprecedented speed. But determining its overall health is more of an art than a science. So perhaps the scientists can help. NASA recently published a fresh batch of satellite images of China’s utility-scale solar boom in Gansu province. While they don’t tell us much about market conditions on the ground, they do illustrate the boom underway in the country. With ample sunshine and a wide-open desert, Gansu is ideal for PV project development. Last year, more than 5 gigawatts of projects were installed in the province, making it a leader. Below are two satellite […]

Japan Building Giant Battery Systems to Store Solar Power

Japanese companies are building some of the world’s biggest battery systems to address one of solar power’s biggest problems–its volatility. Handling the surges in power when the sun shines and storing that energy for use when it is cloudy or dark is a major headache for solar power producers and the utilities they supply. Mitsubishi Electric Corp.6503.TO +0.79% and NGK Insulators Ltd.5333.TO +1.68% are assembling a 50,000 kilowatt battery system for Kyushu Electric Power Co.9508.TO +0.41% to study ways to better accommodate solar power. A slightly smaller, 40,000 kilowatt battery system is under construction in Minami Soma, north of the Fukushima Daiichi nuclear power plant, for Tohoku Electric Power Co.9506.TO +0.52% to conduct similar research. The government is financing both projects at a total cost of ¥31.7 billion ($257 million), a government official said. Power companies have cited the volatility of supply as a reason for refusing to accept […]

The Way Humans Get Electricity Is About to Change Forever

The renewable-energy boom is here. Trillions of dollars will be invested over the next 25 years, driving some of the most profound changes yet in how humans get their electricity. That’s according to a new forecast by Bloomberg New Energy Finance that plots out global power markets to 2040 1 . Here are six massive shifts coming soon to power markets near you: 1. Solar Prices Keep Crashing The price of solar power will continue to fall, until it becomes the cheapest form of power in a rapidly expanding number of national markets. By 2026, utility-scale solar will be competitive for the majority of the world, according to BNEF . The lifetime cost of a photovoltaic solar-power plant will drop by almost half over the next 25 years, even as the prices of fossil fuels creep higher. Solar power will eventually get so cheap that it will outcompete new […]

Could Middle East Switch From Oil to Renewables?

Decreasing prices in solar power could provide opportunities for oil-poor countries “Costs have halved in just three years,” energy consultant Robin Mills noted last week , “meaning solar can now beat all conventional generation apart from the very cheapest gas.” Mills cited the bids in Jordan’s recent solar auction, which were just over 6 US cents per kilowatt-hour. These were just slightly above the record 5.84 cents from Acwa Power last November for the 200 MW second phase of Dubai’s Mohammed bin Rashid Al Maktoum solar park. It could be Egypt’s turn next, Mills suggested, as the North African country struggles with a gas and power crisis and is reportedly working on 6,500 MW of solar deals. “Petroleum-poor countries such as Jordan should seize the opportunity now to boost their economic and energy security,” Mills, the head of consulting for Dubai-based Manaar Energy, urged in an article for Abu […]
