California-based company Cereplast has revealed that it is developing breakthrough technology to transform algae into bioplastics, and predicts that it could replace 50% or more of the petroleum content used in traditional plastic resins.

Cereplast already makes plastic from renewable material such as corn starch, tapioca, wheat and potatoes, but is keen to trumpet the advantages of the new approach.

According to Frederic Scheer, Founder, Chairman and CEO of Cereplast, “Algae-based resins represent an outstanding opportunity for companies across the plastic supply chain to become more environmentally sustainable and reduce the industry’s reliance on oil.”

Here’s a feather in the cap of renewable energy supporters.

When the (baseload, coal and nuclear) power went out after storms in Muskegon, a mobile renewable energy unit came to the rescue.

A two year study led by the University of Leeds in the UK aims to develop a system that can harness kinetic energy from marching soldiers.

The $1.5 million plan will focus on finding a way to convert human energy into usable power for military field applications. It is part of the larger “battery-free soldier” project that also includes development of solar and body heat-harvesting technologies for the military.

Soldiers carry around electronic equipment such as large flashlights, and power sources in the form of batteries can weigh as much as 10 kilograms of a foot soldier’s usual 75 kilogram pack. Clearly, having a power source they can carry around will be beneficial. Research leader Professor Andrew Bell of Leeds says,

“As well as the obvious green issue of using so many batteries, [the system] could also reduce a soldier’s pack weight by around 15 per cent. And this technology could potentially have lots of applications in civvy street too.”

Earlier today the Zwentendorf nuclear plant in Austria reopened as a solar power station, making it the largest facility of its kind anywhere in the country.

Following its completion over 30 years ago, the plant’s operation was fiercely contested - culminating in a 1978 national referendum forcing it to close. Since then it has lain dormant as a visible testament to Austrian concerns over nuclear energy.

Now, following a €1.2 million investment the plant has reemerged as a major renewable energy production facility.

Major US renewables company Astonfield is set to invest a massive $2 billion in India over the next five years, the largest single cash-injection in renewable energy ever seen in the sub-continent.

The deal will generate about 1,000 MW of power, most of it from solar sources.

Much of the proposed $2 billion investment will go towards building solar-photovoltaic powered projects with a capacity of 500 MW.

There is enough energy stored beneath the earth’s surface to power all of our energy demands thousands of times over. The problem is, it’s thousands of feet beneath us. Out of sight. Out of mind. But what if we could get to it? What if we could harvest that power?

Achieving a goal of 100 percent energy independence is a little closer for San Jose thanks to a momentous move by the City Council today. The City Council authorized the City Manager to negotiate and execute a Memorandum of Understanding (MOU) to develop potential lease terms and guidelines for developing an organics-to energy bio-gas facility.

Experts say only a fraction of the Sahara, probably the size of a small country, would need to be covered to produce enough energy to supply the whole of Europe. Written by David Adam at the Guardian.

Russian Prime Minister Vladimir Putin has approved a government order to increase renewable energy in Russia from less than 1% to 4.5% of the nation’s total energy by 2020.

The Kremlin’s order to ramp up renewable energy has set targets of 2.5% by 2015 and 4.5% by 2020. That translates into 45.2 billion kiloWatt hours of renewable energy production by 2020, based on the country’s current electricity production.

To reach these goals, the government will fund small hydro, tidal, geothermal, wind, solar and biomass energy facilities. Wind energy, for instance, is slated to expand from 12 MW (2005) to some 7000 MW by 2020.

Developing Russia’s economically recoverable renewable energy could cut some 990 million tons of CO2 emissions a year, according to the Organization for Economic Cooperation and Development (OECD). (PDF) To put that number in perspective, it would be the equivalent of preventing two-thirds of the CO2 emissions of the United States from entering the atmosphere. This estimate, as well as Russia’s renewable energy statistics, doesn’t take into account large hydroelectric projects, which already account for 21% of Russia’s total energy.

According to a new study conducted by the Lawrence Berkeley National Laboratory, The average installed costs for photovoltaic cells (in real 2007 dollars) went down from $10.50-per-watt in 1998, to $7.60-per-watt in 2007.

What’s most amazing about this report is that it appears to validate a whole slew of state and local solar initiatives. The researchers found that—despite the many, many reported advances to solar cell efficiency—most of the savings during this nine year period came from reductions to installation and external hardware costs.

Sun Well Solar—a subsidiary of the notoriously poor CD and DVD manufacturer, CMC Magnetics—has announced today that it is one month ahead of schedule in the ramp-up of its new photovoltaic production line.
