The Moral Question Of Our Time: Can We Share The Planet?

UN Climate Report: We Must Focus On 'Decarbonization', and It Won't Wreck the Economy - "The basic message is simple: We share a planet. Let's start acting like it." [more inside]

Indirect fusion's nothing less than HiiiPoWeR

Installed solar capacity is growing by leaps and bounds, led by Walmart and Apple, and helped by bonds backed by solar power payments,[*] which have sent industry stocks soaring, even as molten salt and new battery technologies come on line to generate storage for use when the sun doesn't shine. Of course we could always go to geostationary orbit -- or the moon -- as well we may (if politics allow it) as thirst from the developing world grows beyond the earth's carrying capacity.

The Green Mafia

“Uncle Vincenzo,” implored the businessman, Angelo Salvatore, using a term of affection for the alleged head of Sicily’s Gimbellina crime family, 79-year-old Vincenzo Funari. According to a transcript of their wiretapped conversation, Salvatore continued: “For the love of our sons, renewable energy is important. . . . It’s a business we can live on.” [more inside]

I love a sun-powered country, A land of deepening mines, of ragged nuclear plants, of biomass and hydropower

While developed countries are pondering whether they should sign up to The Kyoto 2 Protocol and cut greenhouse gas emissions by 5% by 2020, based on 2000 levels which may be of questionable impact, the tiny Pacific territory of Tokelau has ditched its primary source of electricity generation, costly diesel imports, in favour of 100% renewable solar power, becoming the first nation in the world to do so, at a time when the global energy systems of the 21C are struggling towards decarbonisation.

Artificial Leaf

"A practical [inexpensive] artificial leaf has been one of the Holy Grails of science for decades. We believe we [Sun Catalytix] have done it." Video: Professor Daniel Nocera at MIT

More recent events in solar power

Around one year ago we saw some of the recent events in solar power. At that time solar panels topped out at a peak efficiency of around 290W for a 1.99 x 0.99 meter 72-cell module, with a lone rare and expensive 315W module that was used to build team Germany's solar decathlon winning house. Since then prices have dropped a lot, and China is advancing in commodity tech. [more inside]

ending corporate welfare

Get the Energy Sector off the Dole - Why ending all government subsidies for fuel production will lead to a cleaner energy future—and why Obama has a rare chance to make it happen.

Would you like that sunny-side up?!

Solar takes to the skies. The Solar Impulse took flight today, reaching an altitude of 5500 feet over 87 minutes.With a wingspan of over 60 meters, close to that of a Boeing 747, it weighs about as much as a small car. Its 12,000 solar cells generate power for the 40hp engine, with an average speed of 70 kph (44 mph). The team will continue testing the prototype, including a 36 hour overnight flight, before constructing an even lighter, more powerful, more stable plane, with the goal of flying around the world in 2012, traveling both during both the day and at night, without fuel.

Recent events in Solar Power

Solar power continues to become more economical with every passing month. The price of standard monocrystalline/polycrystalline 210W to 300W modules has halved, from above $3/watt to below $1.70/watt in the past 12 months. The Canadian province of Ontario has become the first location in North America to offer an aggressive feed-in tariff comparable to the feed-in tariffs in Germany and Spain, paying above 80 cents/kWh for power generated by small rooftop photovoltaic installations. The US federal government is also offering massive tax breaks for solar installations as part of the 2009 ARRA act. [more inside]

2009 Solar Decathalon

For the second time in two years a team from Germany has won the US Department of Energy's Solar Decathalon. This year's entry was a cube shaped house entirely covered in 300W and 70W solar panels generating a peak of 11.1kW. The DoE has published a complete product directory of all the subsystems and components used to build each house. Another notable design is the Canadian Team North house designed for optimal solar+insulation performance in high latitude climates.

Yesterday's Energy of Tomorrow...and more

Peak Oil, 1925. In 2000, 20% of new buildings will be solar equipped. By the late 1990s, 90% of the world's energy will be nuclear-generated. These and other erroneous projections are being collected as part of the Forecast Project on the website Inventing Green: The Lost History of Alternative Energy in America.

Infrastructures / Networks / Environments

The globe’s networked ecologies of food, water, energy, and waste have established new infrastructures and forms of urbanism. While these ecologies exist at the service of our contemporary lifestyles, they have typically remained hidden from view and from the public conscience. Infranet Lab is studying the shifting / changing conditions. [more inside]

Forget hybrid cars. Spring for a hybrid house.

Enertia is producing "innovative new homes of remarkable strength, economy, and beauty, brought to life by an elegant new architecture and the discovery of a new source of pollution-free energy." The design took first prize in the Modern Marvels/Invent Now competition (previously). In an interview, the inventor, Michael Sykes, says "he was inspired by the way the earth’s own atmosphere keeps the planet at a relatively constant comfortable temperature despite the frigidity of space." He also notes that his wife calls herself a "homemaker," natch.
