March 11 marks the five-year anniversary at the Fukushima nuclear power plant in Japan. After the disaster, officials have been on the hunt for alternative energy solutions. Now, Japanese electronics firm Kyocera has begun construction on what will be the world's largest floating solar farm, just outside Tokyo. The Yamakura dam power plant will use more than 50,000 solar photovoltaic panels covering nearly 2 million square feet. Japan is a country short on space, so energy solutions that aren't built on land are a welcome sight to many. As the Guardian recently reported, the country is increasingly dependant on imported fossil fuels, to the detriment of its carbon footprint goals. The solar array is being constructed upon a reservoir with hopes of providing enough energy for roughly 5,000 homes when finished in 2018. Despite its size, the plant is comparatively small to land-based solar farms. Expected to produce 13.7MW when complete, this more than 28 times smaller than the 392 Ivanpah Solar Power Facility in San Bernardino, CA. According to Kyocera TLC Solar, "the project will generate an estimated 16,170 megawatt hours (MWh) per year — enough electricity to power approximately 4,970 typical households — while offsetting about 8,170 tons of CO2 emissions annually. This is equal to 19,000 barrels of oil consumed." "With the decrease in tracts of land suitable for utility-scale solar power plants in Japan due to the rapid implementation of solar power, Kyocera TCL Solar has been developing floating solar power plants since 2014, which utilize Japan’s abundant water surfaces of reservoirs for agricultural and flood-control purposes," the firm added.

Called out by Greenpeace for lack of transparency, Amazon commits to building solar farm in Virginia to power its data centers
E-commerce giant Amazon is under fire from groups to catch up to its tree-hugging counterparts. To boost its "green" credentials, the company has announced the building of a new solar farm in coal-reliant Virginia to power its numerous data centers in the region. After scoring abysmally in a Greenpeace report that ranked big tech firms by renewable energy achievements and transparency, Amazon announced a partnership with Community Energy on June 10 to build an 80-megawatt solar farm in Virginia’s Eastern Shore in Accomack County. It will be the largest solar facility in the state to date. Greenpeace called out Amazon in May for not elaborating on its plans to achieve 100 percent renewable energy. “Amazon lags behind its competitors in using renewable energy for its cloud-based computer servers,” Todd Larsen, executive co-director of Green America, told EcoWatch. “Unlike most of its competitors, it fails to publish a corporate responsibility or sustainability reporting, and it fails to disclose its emissions and impacts to the Carbon Disclosure Project. We are calling on Amazon.com to take steps to be transparent about its emissions and to rapidly move to renewable energy.” In April, Amazon reported that 25 percent of its global infrastructure is powered by renewable energy. Its goal, by 2016, is to raise that figure to 40 percent. The Greenpeace report, Clicking Clean: Building a Green Internet, showed Amazon lagging far behind peers such as Google and Apple, the latter of which runs all of its data centers on renewables and earned a top score in the report. Amazon’s solar farm will deliver about 170,000 megawatt hours of electricity, enough to power 15,000 homes. While Greenpeace applauded Amazon on its prudent move, the environmental group estimates that the solar farm’s output would suffice to meet only a “single-digit percentage” of Amazon’s total energy demand in Virginia, according to Fast Company. The tech company’s data centers in that region are the lifeblood of its Amazon Web Services (AWS), used by some of the Internet’s biggest names including The New York Times, The Huffington Post, Buzzfeed, Pinterest, and Tumblr. The energy demands for such large-scale cloud computing are understandably mammoth. Last January, Amazon announced that it would build a 150 megawatt wind farm in Benton County, Indiana, which has a higher capacity. Earlier this year, AWS customers including Tumblr, HuffPo, and Hootsuite wrote to Amazon asking it to be more transparent about its environmental reporting.
