Solar Powered Farming Can Improve Food Security

Since diving into the deep end when it comes to energy issues, almost every day sees new concepts, approaches, and technologies — fascinating, exciting, even hope-inspiring at times. And, to top it all off, so many of these are truly Energy COOL as well.

Innovative combinations of rather straightforward, well-in-hand technologies can offer real solutions to problems while creating new opportunities.

Several weeks ago, a group of researchers published an article in the Proceedings of the National Academy of Sciences documenting how relatively low-powered solar systems offer the potential to increase food supplies in impoverished arid regions while reducing demands for fertilizers and other costly (in fiscal and other terms)additives.

Bioethanol From Dates: Iraq Approves Plan to Boost Agriculture Economy

written by Ceylan Thomson

Iraqi officials have endorsed a plan to convert dates into biofuel, an innovative project they hope will boost a once-thriving agriculture economy burdened by years of drought, government sanctions and war.

A United Arab Emirates-based company will produce bioethanol from the dates that farmers can no longer use because they are rotting, said Faroun Ahmed Hussein, head of Iraq’s date palm board.

The nation produces about 350,000 tons of dates annually, but consumes only about 150,000 tons.

Air Pollution in China Contributing to Drought — Food Shortages Possible

written by Ceylan Thomson

Severe air pollution in China’s heavily industrialized east is impeding the formation of rain clouds and contributing to a drought in northern China, according to a new study. The study, which looked at rainfall and pollution patterns for the past 50 years, concluded that pollution has reduced the number of days of light rain in eastern China by 23 percent.

Atmospheric scientist Yun Qian of the U.S. Department of Energy’s Pacific Northwest National Laboratory said that the large number of aerosols in China’s polluted skies has led to the formation of rain droplets that are up to 50 percent smaller than rain droplets in clean skies. The smaller droplets do not as readily form rain clouds, which means that lighter rainfalls valuable to agriculture — ranging from a drizzle to accumulations of .4 inch per day — are occurring less frequently, according to the study, published in the Journal of Geophysical Research-Atmospheres.

Obama Government Reports On Local Impact Of Global Climate Change

written by Ceylan Thomson

The US Federal government released a major report this week. The report summarizes the science and the impacts of climate change on the United States, now and in the future. It focuses on climate change impacts in different regions of the US and on various aspects of society and the economy such as energy, water, agriculture, and health. The report is the work of 12 federal agencies including the EPA, DOD, DOC, NASA, and others. It’s written in plain language, with the goal of better informing public and private decision making at all levels.

The Key Findings of the report are:

Ethanol: Remixed

written by Jeff Kart

No, it’s not the latest CD from Verve, it’s the latest rumble from industry groups and states: Raise the percentage of ethanol blended into unleaded gasoline.

The current cap is 10 percent. An ethanol trade group called Growth Energy has formally requested an increase to 15 percent, saying it will create more than 100,000 jobs and pump more than $24 billion into the economy, Reuters reports. There’s also the added benefit of increasing the demand for ethanol by 6 billion gallons a year, MSNBC says.

The U.S. Environmental Protection Agency is studying whether a higher blend would harm older cars. Some newer vehicles are designed to run on E-85 (an 85 percent blend).
