The U.S. Court of Appeals for the District of Columbia Circuit, invalidated a set of U.S. Environmental Protection Agency (EPA) air quality rules, enacted to cut pollution from coal fired power plants in Ohio and eastern states.
The rules were intended to cut sulfur dioxide and nitrogen oxides compounds, which can travel hundreds of miles and create smog, soot and acid rain problems in downwind states, and would have required utilities in 28 states and the District of Columbia to install new pollution controls.
Although EPA’s officials said that by 2014 the requirements would yield health benefits for 240 million Americans, utilities and business groups find the rules costly, and arbitrary.

Chinese solar industry faces weak sales, price war
Chinese solar companies are having political and financial problems that might lead to possible mergers, bankruptcies, factory closures or layoffs.
According to financial analysts, over the past two years the price of polysilicon wafers used to make solar cells, has plunged by 73 percent, the price of cells has fallen by 68 percent and modules’ price by 57 percent.
Chinese manufacturers are also dealing with challenges such as the potential impact of U.S. and European anti-dumping measures, in response to complaints Beijing improperly subsidizes companies, the Chinese government policies, which encouraged hundreds of small companies to rush into the industry, and the new Korean companies that are pouring into the solar industry.
GE and Houweling’s Tomatoes Unveil the First Greenhouse Combined Heat and Power Project in the US with Carbon Dioxide Fertilization
In Camarillo California GE and its customer Houweling’s Tomatoes, a greenhouse tomato grower, make public the first combined heat and power (CHP) project in U.S that captures carbon dioxide (CO2) for use in plant fertilization. The plant provides heat, power and CO2 to Houweling’s 125-acre tomato greenhouse.
The project represents the launch of GE’s is first gas engine featuring double turbocharging, which makes it very efficient. The Houweling’s CHP system also provides 8.7 MW of electrical power, 10.6 MW of thermal power and an efficiency of nearly 90 percent.
The CHP plant will enable flexible generation and contribute electric power to Houweling’s local utility during peak daytime demand periods with a very short response time.
Community Solar, Get Renewable without the Panels
We all are pretty conscious of the importance of renewable energy, and visualize solar energy in the form of rooftop, solar photovoltaic panels as one of main approach to help reduce the use of fossil fuel, and at the same time , as an opportunity to reduce our electricity bill. But in case rooftop solar is not the option for you, now there is a concept known as community solar or gardens.
The idea is to install thousands of solar panels in a central location rather than spread across individual rooftops. Xcel Energy, a mayor U.S. electricity and natural gas company with operations in eight Western and Midwestern states, is launching the largest community solar project in Colorado, The Solar*Rewards Community.
The community installations will be developed, built and managed locally. Xcel Energy is one of the first utility companies in the country to offer incentives for their installation and use. Incentives will be offered for up to nine megawatts (MW) of power.
