POPSSolar Will Beat Oil This article gives me some hope. A bit more: "Enough total solar energy shines on the earth during a 40-minute period of time to power the entire world economy for a year. We only need to harness a tiny portion of this sunshine to make a huge difference in the world: environmentally, politically and economically."

POPSCan we harness energy from outer space? While nuclear fusion has already been tested with the hydrogen isotopes deuterium and tritium, those reactions give off the majority of their energy as radioactive neutrons, raising both safety and production concerns. Helium-3, on the other hand, is perfectly safe. It doesn't give off any pollution or radioactive waste and poses no danger to surrounding areas. helium-3 has two protons but only one neutron. When it's heated to very high temperatures and combined with deuterium, the reaction releases incredible amounts of energy. Just 2.2 pounds (one kilogram) of helium-3 combined with 1.5 pounds (0.67 kilograms) of deuterium produces 19 megawatt-years of energy Roughly 25 tons of the stuff could power the United States for an entire year.

POPSThe key to oil independence is a new electrical grid It seems that with alternative sources of energy, such as wind and solar, the United States has the potential means to substantially reduce our dependence on oil - especially once plug-in cars are on the market. But until we substantially upgrade our nation's electrical grid with modern technology that will enable the energy created by these sources to be transmitted intelligently around the county, their impact will be limited. It's going to take a greater commitment from Congress to jump start this. Making it happen will provide a huge boost to our economy, environment and political leverage with the Middle East, Russia, Venezuela and more.

POPSPelosi's Farting Up the Wrong Tree Get some bean-o for your gassy ignorance! Cont..You know what else she’d learn if she read that EIA link? She’d learn that natural gas isn’t brought to us by magic fuel fairies but by the same arrangement that brings us oil. She’d learn how you drill for gas using the same equipment as you do for oil and that sometimes we drill for gas and oil at the same time using just one well. She’d also learn how natural gas is carried by evil pipelines, just like the oily pipelines that might endanger caribou if they didn’t like them so darned much. Of course, that all assumes that she’s the least bit interested in learning anything that might demolish her own infantile view of how we get energy in this country and what we’re going to need to do to keep ourselves supplied well into the future. Based on her behavior in the last few weeks, it seems the only thing she’s interested in is making herself a couple more million dollars and scoring cheap political points.

POPSNano-Solar Power -Will it Be the Next Revolutionary Technology? Not that the technology is perfect. The system can absorb energy very well, but that's no good to anyone until they work out a way to harvest it from the sheet - when you're dealing with a hyper-complex web of millions of units oscillating at trillions of cycles per second, you can't just solder copper wires to the ends and call them plus and minus. This isn't a mistake or a weakness in the concept though; it's an issue because no-one has ever done this before. You know, the kind of thing that happens with cutting edge invention.

POPSTwo Large Solar Projects Planned for California While I'm not extremely keen on these sort of plants -- there's no real reason to centralize solar generation like this -- it's nice to see that solar's being taken seriously. Given recent advances in photovoltaic technology, the price is coming down enough for it to be put anywhere the sun shines. In other words, there's no reason to use up huge expanses of land when you can do the same thing on rooftops. Still, any time new generating capacity comes from green tech, it's good news.

POPSAbout That Pelosi, Pickens Plan To Pick Our Pocket
but the then necessary development of the infrastructure and conversion to such energy will take even longer. We are not going to abandon gas and oil any time soon, no matter what the loudest advocates of renewable energy sources insist. As a writer noted at Fosters.com, a sane energy policy will require tuning in to a program of multiple sources. Fossil fuels -- developed and yet to be developed -- wind power nearing a scope envisioned by T. Boone Pickens, solar power, nuclear power, biomass, geothermal power and sources we haven't thought of yet are in our future - as in waaay in our future. Pickens' plan is bold — too bad it won't work The Pickens Plan isn't the boon for energy independence that it purports to be. Dallas billionaire investor and oilman-turned-wind-farmer Boone Pickens unveiled an audacious plan that he hopes will prod policymakers into a more realistic discussion of energy issues. http://www.chron.com/disp/story.mpl/front/5882292.html

POPSAir Force and Renewables This is a nice read on the role of government's involvement in energy tech. It's also interesting to see SunPower (nasdaq: SPWR) here. That stock is off 40% from a 52-week high but still sells for 5.6 times sales.
