Solar is on the Upswing with Lower prices
In his March 9 column ("Pricey power in the mix"), Rick Martinez was snared by a trap that befalls many when looking at North Carolina energy policy. His problem comes from comparing new renewable power plants with existing conventional power plants. His analysis would have been more helpful had he compared the cost of new renewable energy to energy from new coal, nuclear or natural gas plants. The unfortunate truth is that any new power plant will be more expensive than what we currently have. And given the continued growth of our state, we will need new generation. In order to keep future energy prices as low as possible, renewables will be an important element in our state's future energy mix. The price of conventional sources of energy (coal, nuclear and natural gas) is rising inexorably, but the price of renewables is falling. Last November, the U.S. Energy Information Agency updated its analysis of the projected cost to build generating plants. From 2010 to 2011, the cost of coal, nuclear and natural gas plants increased 25 percent to 39 percent, while solar photovoltaic costs dropped 25 percent. When one includes the cost of fuel, energy from wind farms costs less than that from new coal, nuclear and natural gas facilities.

Japan nuclear crisis sends investors to the Sun
As Japan's nuclear crisis unfolds, energy and environmental experts said that investor confidence in the technology was already beginning to wane, with renewable energy and fossil fuels the likely beneficiaries.
"Shares in renewable energy industries yesterday rose while most other energy stocks fell," said Clare Brook, fund manager of leading green investment group, WHEB, in London. "This tragedy comes on top of the oil price rise, the BP disaster in the Gulf of Mexico and unrest in the Middle East, all of which has made renewables more attractive. We would expect investment in renewables, especially solar, to increase. Nuclear has become politically unacceptable," she said.
Rupesh Madlani, a renewables analyst at Barclays Capital in London agreed. "At the very least, we would expect significant investments in nuclear power to be delayed, or deferred, for one to two years."But some leading environmentalists who have backed the technology as a low-carbon alternative to fossil fuels said the accident should not slow new nuclear investment.
The climate scientist James Lovelock said the problems in Japan should not put people off nuclear power. "There is a monstrous myth about nuclear power. I would make a strong guess that of the tens of thousands of people killed in Japan, none of them will be from nuclear power."

Solar Stocks Soar during meltdown
March 14,2011 Mathew Lynley -VentureBeat
Call solar power the second best thing in clean energy. Solar power stocks have soared since concerns about a nuclear meltdown in one of Japan’s nuclear power plants have sent investors running to alternative clean energy companies.
The market move indicates that investors in clean energy prefer nuclear power as a first option over solar power. That’s because solar power, which uses flat photovoltaic panels that absorb sunlight and convert it to electricity, is still in infancy. Typical wafer-style solar panels can capture around 30 percent of the sunlight shining on them and convert it into electricity. Flexible, thin-film photovoltaic cells that can be placed on most surfaces can only capture anywhere from 15 to 20 percent of the sunlight shining on them.
Nuclear power produces energy by generating controlled nuclear reactions that produce tremendous amounts of heat. That heats up water, which produces steam that spins a turbine. The turbine produces electricity. Nuclear power is considered cleaner than fossil fuel burning power plants, which use natural gas, petroleum and coal. Burning all of those produces greenhouse gasses.
But a critical nuclear reactor nearly experienced a meltdown after an 9.0-magnitude earthquake rocked the northeastern part of Japan last week. Plant officials were able to halt the nuclear reaction by withdrawing the fuel rods that power the reactor, but residual reactions and heat were still causing problems as of Monday. Investors are basically betting that the media frenzy that has taken off as a result of the snafu will generate some additional buzz for solar power, another form of clean energy that has no negative byproducts.

Unclean Water Kills over 4,000 Children a Day

Dirty Water Kills 4,000 Children a Day
By Thalif Deen
UNITED NATIONS, Sep 28 (IPS) - The statistics are mind-boggling: of the more than six billion people in the world today, over one billion have no access to improved drinking water - a basic necessity for human life - and about 2.6 billion people do not have access to improved sanitation. And according to the U.N. children's agency UNICEF, polluted water and lack of basic sanitation claim the lives of over 1.5 million children every year, mostly from water-borne diseases. "Despite commendable progress," says UNICEF executive director Ann Veneman, "an estimated 425 million children under 18 still do not have access to an improved water supply, and over 980 million do not have acce ss to adequate sanitation." She said those who die are by no means the only children affected. "Many millions more have their development disrupted and their health undermined by diarrhoeal or water-related diseases." In a 33-page report titled "Progress for Children: a Report Card on Water and Sanitation" released Thursday, UNICEF says these "tragic statistics" underscore the need for the world to meet its commitment to one of eight Millennium Development Goals (MDGs): to halve by 2015 the proportion of people without sustainable access to safe drinking water and basic sanitation.
This report is very disturbing and has burdened VP of Solar Fusion -Ken Boyle and "Can no longer sit back and do nothing" so Solar Fusion has announced its strategic alliance with a US government approved portable Solar Water purification system to provide clean water to children throughout the World. "I am calling this movement Project Reverb" says Boyle, "we will team up with people throughout the World who have a heart to make a difference and leave a lasting legacy". “Changing the World One drop at a time”
