The most common mistake made when sizing battery banks is not having accurate load information. If manufacturer's data is not available for a particular load, steps should be taken to measure actual power use instead of making a guess. Small mistakes can have a big impact, causing the end user to eventually lose power and potentially require a replacement battery bank sooner than expected. Since most battery based renewable energy systems are off-grid and all power will be generated and stored on-site, it's critical that the designer understand the nature of the loads the system is designed to run.

Want an electric vehicle with more than a piddly couple-hundred mile range? Apparently you have to build it yourself and follow in the footsteps of the Japan Electric Vehicle Club, which broke the Guinness World Record last weekend by driving 623.76 miles (just over 1,000km) on a single charge in its customized Daihatsu Mira. The trip took 27.5 hours traveling around what appears to be the famous Tsukuba circuit in Shimotsuma, Japan. The car was powered by 8,320 Sanyo li-ion cells, each weighing about 44 grams, for a grand total of 807lbs -- more than half the weight of a stock Mira. While we're sure Daihatsu helped with this build, it's worth noting that this is not an official project of the company, meaning the 100 mile Nissan Leaf is about as close as you're going to get to this feat for the near future.

The heads of Tesla Motors Inc. and Toyota Motors Corp. surprised the auto world Thursday by announcing a partnership to develop and build electric cars at a recently shuttered auto plant in the San Francisco Bay area. Akio Toyoda, CEO of the world's largest automaker, said Toyota will invest $50 million in Tesla when the company begins selling stock to the public, and Tesla CEO Elon Musk said his company will purchase the New United Motor Manufacturing Inc. factory, known as Nummi, in Fremont where the Model S electric sedan will be built. Analysts said the partnership enhances the credibility of Tesla, a Silicon Valley start-up just a few years ago, and boosts Toyota's image after being fined a record $16.4 million for its slow response to an accelerator pedal recall.
According to a new report from NanoMarkets' Smart Grid Analysis, AC and DC Smart Grid transmission systems are expected to grow from $10.8 billion in 2010 to $17.7 billion in 2015 driven by government mandates for renewable energy integration and grid reliability and by economic development in Asia

Europe will consume about 20m tonnes a year of renewable biodiesel by 2020 due to stricter regulations driving up demand for the ‘greener’ product, says Matti Lievonen, president and chief executive officer for Neste, a leading producer of biodiesel. “Renewable energy will also very much be in demand in Asia. Based on an anticipated population increase of one billion by 2030, there will be a 50% increase in energy demand especially in the areas of biofuels, solar and wind energy.”
