The world needs a "revolution" in science and technology to solve global warming, says Energy Secretary Steven Chu. Chu, a Nobel Prize-winning physicist, made the remarks in today's New York Times. The article was short on specifics, but Chu, former director of Lawrence Berkeley National Laboratory, said Nobel-level breakthroughs were needed in electric batteries, solar power and crops that could be turned into fuel. "Science and technology can generate much better choices," Chu, a long-time proponent of alternative energy development, told the newspaper. "It has, consistently, over hundreds and hundreds of years." Among the points he made:

James Dyson is working on a solar-powered car to match the success of his bagless vacuum cleaner. Engineers at the entrepreneur's Wiltshire HQ are developing a lightweight electric motor that could power a family saloon for hundreds of miles.

Will support energy efficiency efforts nationwide that will create 87,000 jobs and cut energy bills for families Washington DC -- Vice President Joe Biden and Energy Secretary Chu today detailed an investment of nearly $8 billion in state and local weatherization and energy efficiency efforts as part of the President's American Recovery and Reinvestment Act. With an investment of about $5 billion through the Weatherization Assistance Program and about $3 billion for the State Energy Program, the Department of Energy will partner with state and local governments to put 87,000 Americans to work and save families hundreds of dollars per year on their energy bills. To jump-start job creation and weatherization work, the Department of Energy is releasing the first installment of the funding - about $780 million -- in the next few days. The Department will release additional funding over time as states demonstrate that they are using the funding effectively and responsibly to create jobs and cut energy use.

I don't know what's been happening lately with everybody, but it seems that more and more people are trying to charge their phones or iPhones or iPods using energy imported from human movement. Remember those movies presenting slaves hundreds of years ago spinning a huge wheel to provide the emperor with water and energy? They did not do it for fun, yet nowadays there are two recent mediatized inventions that caught my eye. Curiously enough, they are being developed by two telecom operators:

As soon as I have finished this column I will jump on the train to Kent. Last year Al Gore remarked: "I can't understand why there aren't rings of young people blocking bulldozers and preventing them from constructing coal-fired power plants." Like hundreds of honorary young people, I am casting my Zimmer frame aside to answer the call. Everything now hinges on stopping coal. Whether we prevent runaway climate change largely depends on whether we keep using the most carbon-intensive fossil fuel. Unless we either leave it - or the carbon dioxide it produces - in the ground, human development will start spiralling backwards. The more coal is burnt, the smaller are our chances of future comfort and prosperity. The industrial revolution has gone into reverse.

(NaturalNews) A new combination of nano and solar technology has made it possible for solar electric generation to be cheaper than burning coal. Nanosolar, Inc. has developed a way to produce a type of ink that absorbs solar radiation and converts into electric current. Photovoltaic (PV) sheets are produced by a machine similar to a printing press, which rolls out the PV ink onto sheets approximately the width of aluminum foil. These PV sheets can be produced at a rate of hundreds of feet per minute.

Billionaire T. Boone Pickens brought is traveling energy road show to the Salt Palace Convention Center on Thursday, and hundreds of Utahns came to hear what he had to say. The oil tycoon and mega-successful hedge-fund manager promoted his strategies for alternative fuel development. The Pickens Plan urges Americans to break their reliance on foreign oil by using clean alternatives, including natural gas, wind, solar and nuclear power.

Renewable Energy World has an article on the state of play in the ocean energy market - Harnessing the Tides: Marine Power Update 2009 One hundred and forty-one years ago, the relentless sea off Scotland's coast inspired the following observation from native son and author George MacDonald. "I climbed the heights above the village, and looked abroad over the Atlantic. What a waste of aimless tossing to and fro! Gray mist above, full of falling rain; gray, wrathful waters underneath, foaming and bursting as billow broke upon billow…they burst on the rocks at the end of it, and rushed in shattered spouts and clouds of spray far into the air over their heads. "Will the time ever come," I thought, when man shall be able to store up even this force for his own ends? Who can tell?"

Scientists have found new evidence that the Earth's natural feedback mechanism regulated carbon dioxide levels for hundreds of thousands of years. But they say humans are now emitting CO2 so fast that the planet's natural balancing mechanism cannot keep up.

WASHINGTON (April 23, 2008) - An investigation of the Environmental Protection Agency released today found that 889 of nearly 1,600 staff scientists reported that they experienced political interference in their work over the last five years. The study, by the Union of Concerned Scientists (UCS), follows previous UCS investigations of the Food and Drug Administration, Fish and Wildlife Service, National Oceanic and Atmospheric Administration, and climate scientists at seven federal agencies, which also found significant administration manipulation of federal science.

A young Google executive who helped ignite Egypt's uprising energized a cheering crowd of hundreds of thousands Tuesday with his first appearance in their midst after being released from 12 days in secret detention. "We won't give up," he promised at one of the biggest protests yet in Cairo's Tahrir Square. Once a behind-the-scenes Internet activist, 30-year-old Wael Ghonim has emerged as an inspiring voice for a movement that has taken pride in being a leaderless "people's revolution." Now, the various activists behind it - including Ghonim - are working to coalesce into representatives to push their demands for President Hosni Mubarak's ouster. With protests invigorated, Vice President Omar Suleiman issued a sharply worded warning, saying of the protests in Tahrir, "We can't bear this for a long time, and there must be an end to this crisis as soon as possible," in a sign of growing impatience with 16 days of mass demonstrations. For the first time, protesters made a foray to Parliament, several blocks away from their camp in the square. Several hundred marched to the legislature and chanted for it to be dissolved.

Even with those efforts we support we still have to make hard choices and it is not as easy when struggling against the giant oild companies.

Feinstein is working on legislation that would designate hundreds of thousands of acres of desert land as a national monument, which would put them off-limits for solar and wind energy projects. That could result in a green- versus-green confrontation, pitting those who want to protect the desert ecosystem against those who believe renewable-energy projects are a vital part of the struggle to avert catastrophic climate change.

SHANGHAI is rich in clean green wind power and the city is constructing more and more windmills as part of a sustainable energy plan. Zhang Qian flips the switch. The sails of hundred-meter-high windmills rotate in the wind in the mudflats of suburban Shanghai. Row upon row of turbines with huge vanes are generating new clean electricity. Shanghai is rich in sustainable wind resources and is increasing its wind energy capacity as part of an overall plan to reduce pollution and develop clean energy.

The Guardian has an article on a report from Greenpeace, the European Solar Thermal Electricity Association and the International Energy Agency's SolarPACES group on the potential for solar thermal power to supply a large proportion of our energy needs (why they limit it to 25% is a mystery to me) - Concentrated solar power could generate 'quarter of world's energy'. Solar power stations that concentrate sunlight could generate up to one-quarter of the world's electricity needs by 2050, according to a study by environmental and solar industry groups. The technology, best suited to the desert regions of the world, could also create hundreds of thousands of new jobs and save millions of tonnes of CO2 from entering the atmosphere. Concentrating solar power (CSP) uses mirrors to focus sunlight onto water. This produces steam that can then turn turbines and generate electricity. It differs from photovoltaics, which use solar panels to turn sunlight directly into electricity and can operate even on overcast days. CSP only works in places where there are many days with clear skies and is a proven, reliable technology. At the end of 2008 CSP capacity was around 430MW, and worldwide investment in the technology will reach
