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.

The Conference is one of North America's top educational opportunities for solar energy professionals offering hundreds of classes and sessions as well as an exhibit hall with around 200 exhibiting companies.
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.
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.”

Like the dinosaur in the Jeep mirror in the movie Jurassic Park, I think it the prospect of low carbon hydrocarbon fuel is a lot closer than it appears. Unlike the dinosaur, it's not scary. It's a good future.
The Solar Energy Industries Association (SEIA) today released an independent study projecting the positive economic impact of the Department of Treasury Grant Program (TGP) and the Manufacturing Investment Tax Credit (MITC). The study found that extending the TGP and MITC by two years would add 200,000 new domestic jobs to the solar workforce and supporting industries in the United States. Additionally, it would result in 10 gigawatts (MW) of new solar installations by 2016 – enough to power 2 million homes. “The clean energy grant program created in last year’s stimulus bill allowed enough renewable energy to come on line to power four cities the size of Seattle and create over 140,000 new jobs,” Senator Maria Cantwell (D-WA) said. “Extension of the Treasury Grant program is essential to continuing our nascent economic recovery and moving to a cleaner, more distributed 21st energy system.
The Competition may be a far more important Competition than realized. The goal is to beat 100 MPGe and provide beautiful, affordable transportation. That means the equivalent of 100 miles per gallon (gasoline) equivalent. This is done to level the playing field regardless of the fuel being used by the vehicle. Hence the vehicle can be powered by battery stored electricity and the energy usage can be measure equivalently with traditional gasoline.
I wanted to build my own solar system and I can tell you now it's possible with materials bought local in DIY shops and easy to obtain parts from the Internet. No I'm not a technical wonder and I don't have lots of experience working with electricity, I just looked around and taught myself how solar panels are made, how other might have done it and made out of this a workable plan of how I could do it.

The groundbreaking Nissan LEAF is fitted with a system where the air conditioning can be programmed using a mobile like the iPhone or HTC Desire. When they are out and about, drivers can use their phone to communicate with the battery powered, electric vehicle. With just a few clicks, drivers can find out how much battery power the car has left and if they have left it charging, they can ask the vehicle to send a message when power has been fully restored. They can also request what temperature they would like the cockpit to be at when they return to the five-door hatchback.
When it's time to choose an inverter for a PV system, the system owner and the installer have the choice to use a string inverter or micro inverters for the installation. It is important to realistically assess the viability of this technology.
