The US wind power industry still needs subsidy to compete with fossil fuels, according to Germany’s Siemens, one of the world’s largest wind turbine manufacturers. Lisa Davis, who took over in August as the head of Siemens’ global energy business, told the Financial Times that although wind power in the US was close to “grid parity” – the level at which it becomes competitive with other sources of electricity – “we’re not there yet”. Her comments come as the US industry is urging Congress to reinstate the tax credit for wind generation, which expired at the end of last year. The American Wind Energy Association has warned that the industry could face falling investment and employment if the credit is not restored quickly. Lazard, the investment bank, calculated recently that in parts of the US with strong wind, it could be a cheaper source of power than gas-fired generation, after steep declines in the cost of turbines. However, Ms Davis argued that costs still needed to be cut further before wind could compete on equal terms with gas. “We’ve not yet got to the point where it’s truly self-sustaining,” she said. “We’ve got to focus on cost competitiveness.”
Is it a solar cell? Or a rechargeable battery? Actually, the patent-pending device invented at The Ohio State University is both: the world's first solar battery. In the October 3, 2014 issue of the journal Nature Communications, the researchers report that they've succeeded in combining a battery and a solar cell into one hybrid device. Key to the innovation is a mesh solar panel, which allows air to enter the battery, and a special process for transferring electrons between the solar panel and the battery electrode. Inside the device, light and oxygen enable different parts of the chemical reactions that charge the battery. The university will license the solar battery to industry, where Yiying Wu, professor of chemistry and biochemistry at Ohio State, says it will help tame the costs of renewable energy. "The state of the art is to use a solar panel to capture the light, and then use a cheap battery to store the energy," Wu said. "We've integrated both functions into one device. Any time you can do that, you reduce cost." He and his students believe that their device brings down costs by 25 percent.

Solar & Wind - Featured Product
Developed in 2017, the STI-H250™ is consists of two linked torsion beams that rotate simultaneously following the sun's path. They are moved by just one motor, cutting supply and maintenance costs. STI-H250™ dual-row tracker includes backtracking mode to avoid shadowing between adjacent rows and stow function to protect the tracker in extreme wind conditions. For cleaning, vehicles can pass between trackers and each row can be placed in a different position.
