San Francisco mayor calls for city to go 100% renewable by 2020

San Francisco’s mayor wants an all-renewable town.Photo: jfraserWhere could you get 797 people to stand in line outside a nightclub to attend a $100-a-ticket fundraiser for a nonprofit that advocates for solar energy? Not-so-sunny San Francisco, of course. The queue to get into the Vote Solar Initiative annual spring equinox bash snaked down the street Monday, and even the sun made an appearance during a break in the deluge that has been soaking the Bay Area for the past week. Now, I don’t cover the party beat. But as someone who lived in San Francisco during the dot-com boom of …

What we can learn from Japan’s nuclear disaster

Nuclear plants: unsafe, uneconomic, and unnecessary.Photo: Thomas AndersonCross-posted from the Rocky Mountain Institute. As heroic workers and soldiers strive to save stricken Japan from a new horror — radioactive fallout — some truths known for 40 years bear repeating. An earthquake-and-tsunami zone crowded with 127 million people is an unwise place for 54 reactors. The 1960s design of five Fukushima-I reactors has the smallest safety margin and probably can’t contain 90 percent of meltdowns. The U.S. has six identical and 17 very similar plants. Every currently operating light-water reactor, if deprived of power and cooling water, can melt down. Fukushima …

Lesson from Japan: We don’t need nuclear power to solve the climate crisis

Anyone watching the aftermath of the earthquake in Japan can see: The human and ecological costs of nuclear power far outweigh those of any renewable energy.Cross-posted from New Deal 2.0. On March 14, an editorial in The New York Times stated, “This page has endorsed nuclear power as one tool to head off global warming. We suspect that, when all the evidence is in from Japan, it will remain a valuable tool.” I want to argue that, to the contrary, the lesson to be learned from the catastrophe in Japan is that nuclear power is not even part of a sustainable solution to …

Is your area solar-ready? Check out this gorgeous map

Chart: National Renewable Energy Laboratory The places you would go to get some sun aren’t necessarily the places with the most potential for solar energy. The Southwest is a giant hotspot; Florida and Hawaii are only okay. Check out this map to find the solar potential where you live. Read more: “Good Sun,” Xcel Energy

Avoid at all costs

Cost, not Japan crisis, should scrub nuclear power

Please ignore this image.Photo: GlobovisionThe plumes of smoke rising from Japan’s Fukushima Daiichi nuclear reactor create a visceral reaction. But the crisis should not persuade Americans to abandon nuclear power.  Instead, Americans should abandon nuclear power for its prohibitive and uncompetitive costs. The wildly escalting costs of nuclear plants under construction in the U.S. are a perfect example. A pair of proposed nuclear power plants in Florida have “overnight” costs of $3,800 per kilowatt, but since nuclear power plants actually take eight years to construct, the total estimated project costs are closer to $6,800 per kilowatt (kW) of capacity. This …

German sustainable energy lobby steps up to fill the nuclear hole

Can we replace fossil fuels without going nuclear? One German company says so. Unlike nuclear power, coal doesn’t have to wait for failed safety features to pollute the groundwater, pollute the air, and make people sick for miles around. So getting off fossil fuels is a priority — but now a lot of people are thinking twice about nuclear. Germany, which got 23 percent of its power from nuclear last year, is shutting down reactors left and right. To the rescue: The German renewable industry lobby. It says that renewable power — wind, hydro, solar, and biomass — would be …

Solar: It’s not just a California thing anymore

Texas installed 22.6 megawatts of photovoltaics last year.Photo: Duke EnergyThe United States solar businesses boomed, as usual, in 2010, growing 67 percent to $6 billion, according to an annual report [PDF] released Thursday by an industry trade group. That’s been the story for the past several years, but what’s notable is that solar is no longer just a California thing. The industry is expanding to the East. Back in 2004-2005, California accounted for a whopping 80 percent of the U.S. market. In 2010, that share fell to 30 percent, with 258.9 megawatts of the 878.3 megawatts of photovoltaic power installed …


Is the Bloom Box cheaper than solar?

This is part of a series on distributed renewable energy posted to Grist. It originally appeared on Energy Self-Reliant States, a resource of the Institute for Local Self-Reliance’s New Rules Project. The Bloom Box has received a lot of media attention for its plug-and-play approach to electricity from fuel cells. The 100 kilowatt boxes generate electricity from natural gas, with lower carbon emissions than traditional natural gas-fired power plants, and they can be connected right into the grid alongside commercial and industrial buildings. But will this well-marketed, distributed fuel cell make economic sense? Compared to retail electricity prices in a few …

California utilities (just) miss renewable energy deadline

Time’s up.Photo: elfonThe California Legislature is moving to put into law a regulation requiring the state’s utilities to obtain a third of their electricity from renewable energy by 2020. But how did California’s three big investor-owned utilities do in meeting a previous mandate to secure 20 percent of their electricity supplies from carbon-free sources by the end of 2010? Close, but not quite. Overall, the three utilities — Pacific Gas & Electric, Southern California Edison, and San Diego Gas & Electric — are getting 18 percent of their electricity from wind farms, solar power plants, geothermal, and biomass facilities, according …
