'Mega' floating solar power plants open in Japan

Two floating solar power plants capable of providing electricity for 1,000 homes have been completed in Japan.   The latest such "mega-plants" at Nishihira and Higashihira Ponds in Kato City are the work of electronics giant Kyocera Corporation and Century Tokyo Leasing Corporation, and took just seven months to install. The plant's 11,250 modules are expected to generate 3,300 megawatt hours (MWh) every year.   According to Kyocera, besides being typhoon-proof (due to their sturdy, high-density polyethylene and array design) floating solar plants are superior to their land-based equivalents because of the cooling effect of the water, which allows them to function more efficiently. Reservoirs are also an ideal location because the panels produce shade, which reduces water evaporation and promotes algae growth. A report by Korea Water Resources Corporation found that the lower temperatures of the floating modules mean they are 11 percent more efficient than land-based equivalents. The report identified unsolved issues with the plants, too, however. It said the study had to discard data collected when the panels moved in the wind, and said research into new mooring systems was "continually needed".

MIT invention uses solar power to make ocean water drinkable

USAID recently announced the winners of the Desal Prize, part of a competition to see who could create an affordable desalination solution for developing countries. The idea was to create a system that could remove salt from water and meet three criteria: it had to be cost-effective, environmentally sustainable, and energy efficient. The winners of the $125,000 first prize were a group from MIT and Jain Irrigation Systems. The group came up with a method that uses solar panels to charge a bank of batteries. The batteries then power a system that removes salt from the water through electrodialysis. On the most basic level, that means that dissolved salt particles, which have a slight electric charge, are drawn out of the water when a small electrical current is applied. In addition to getting rid of salt (which makes water unusable for crops and for drinking), the team also applied UV light to disinfect some of the water as it passed through the system. Using the sun instead of fossil fuels to power a desalination plant isn't a totally new idea. Larger solar desalination plants are being seriously investigated in areas where water is becoming a scarce resource, including Chile and California. While proponents hope to eventually could provide water to large numbers of people, the technology is still expensive (though prices are dropping) and requires a lot of intricate technology.

Here's Why Apple Is Building Solar Farms in China

Apple just agreed to back two large solar farms in China. It’s the biggest deal of its kind for a U.S. company operating in China. For China, the deal is only a beginning.  China has been installing more renewable-power capacity than fossil fuels for several years, a gap that's growing. In 2015, China will install 15 gigawatts to 18 gw of solar power alone, double the solar deployment in the U.S., according to an analysis by Bloomberg New Energy Finance (BNEF). The chart shows how, in the next 15 years, China is on track to have more low-carbon electricity than the entire capacity of the U.S. power grid. "Think of what their grid will look like in 2030," Michael Liebreich, founder of BNEF, said at the organization's annual summit last week in New York. "A very competitive advantage." For Apple, the 40-megawatt partnership extends Chief Executive Officer Tim Cook's solar aspirations beyond U.S. borders. Cook announced an $850 million deal in February to purchase enough solar to power all its California operations: stores, offices, headquarters, and a data center. By making a similar push in China, the tech giant begins to offset its considerable manufacturing pollution, which is almost entirely overseas.  Many U.S. tech giants—not just Apple—have been criticized for outsourcing their pollution, says Justin Wu, head of Asia research for BNEF. Apple is "hitting back at that whole line of arguments," he says. "This is the beginning of something. Manufacturing in China is going to get greened."

Top 5 Richest Tycoons in Renewable Energy

The growth of the solar industry is truly astounding, particularly in China, the world’s solar leader. Between 2011 and 2012 the Chinese solar market grew by 500 percent. According to a 2014 report by Frost & Sullivan, a consulting firm, the global solar market earned revenues of nearly $60 billion in 2013. The firm estimates that by 2020 it will double to $137.2 billion.   With all this growth, somebody was obviously going to get rich, and it didn’t take long for Oilprice.com to identify some of the biggest beneficiaries of the push toward renewables. The following are 5 of the world’s most successful renewable energy business leaders and their net worth.   1. Li Hejun, Chairman, Hanenergy Holdings. $31.5 billion.  2. Elon Musk, Founder/CEO, Space Exploration Technologies Corp., Tesla Motors. $12.2 billion. 3. Wang Chuanfu, Founder, BYD Company. $5.3 billion. 4.

Wind Power Creates 30,000 Texas Jobs, Generates $85 million in Taxes

The boom in West Texas wind-powered electricity generation has delivered a major economic boost to the region, including creation of over 40 new businesses and 30,000 construction jobs in 57 West Texas counties since 2001, according to data collected by Public Citizen’s Texas office.   The 40 new manufacturers and businesses make everything from wind turbine blades and steel towers to electronics, according to the data. Wind farms also generate over $85 million in taxes annually in rural Texas counties and more than $9 billion in new taxable assets in the last 14 years.   Over a five-month period in 2014 and 2015, Public Citizen’s Texas office collected data on the economic impact of wind development from county appraisers and tax assessors in the 57 West Texas counties. The data includes estimates of investment values, employment, tax revenues, and lease payments by wind farms, and it reflects review of previous research and case studies.

As California Faces Record Drought Levels, Wind Energy Provides A Vital Service

In 2014, wind energy saved 2.5 billion gallons of water in California by displacing water consumption at the state's fossil-fired power plants, playing a valuable role in alleviating the state's record drought. Wind energy's annual water savings work out to around 65 gallons per person in the state - or the equivalent of 20 billion bottles of water, according to the American Wind Energy Association (AWEA).   According to AWEA, one of wind energy's most overlooked benefits is that it requires virtually no water to produce electricity while almost all other electricity sources evaporate tremendous amounts of water.   In California - where the state is combating record drought levels - Gov. Jerry Brown recently signed an executive order to reduce household water consumption by 25%, from about 140 gallons per day per household to 105 gallons. Wind energy's water savings are, therefore, equivalent to what would be saved by nearly one week's worth of the required reductions for a typical household.   In 2008, U.S. thermal power plants withdrew 22 trillion to 62 trillion gallons of freshwater from rivers, lakes, streams and aquifers and consumed 1 trillion to 2 trillion gallons. By displacing generation from these conventional power plants, U.S. wind energy currently saves around 35 billion gallons of water per year - the equivalent of 120 gallons per person or 285 billion bottles of water.

Obama wants to train 75,000 new solar workers by 2020

President Obama launch a new initiative to expand the nation’s solar industry workforce during a visit to Utah’s Hill Air Force Base on Friday, seeking to gain support for his economic agenda in a heavily-Republican state.   The Energy Department will seek to train 75,000 people — including veterans — to enter the solar workforce by 2020, increasing the goal it set in May 2014 by 25,000.   “We’ve got to be relentless in our work to grow the economy and create good jobs,” Obama said after touring the brief tour, adding that other nations are seeking to expand their economies as well. “And that’s why we have to redouble our efforts to make sure that we’re competitive, to make sure that we’re taking the steps that are needed for us to be successful.”
