Bianca NogradyÂ for VOX: Â At 2:46 pm local time on Friday, March 11, 2011, Japan was rocked by the largest earthquake ever to strike its shores. The 9.1-magnitude quake triggered a devastating tsunami that killed more than 15,000 people. It also took out the backup emergency generators that cooled the reactors at the Fukushima Daiichi nuclear power plant complex, causing a series of catastrophic meltdowns. But amid the chaos, the Yanaizu-Nishiyama geothermal power plant in Fukushima prefecture didn't miss a beat. Along with two more of the nine geothermal power plants in the region, the 65-megawatt facility continued to generate power, even as many other power plants around them failed because of damaged equipment and transmission lines."This is big news for many geothermal people around the world," says Kasumi Yasukawa, principal research manager at the Institute for Geo-Resources and Environment in Japan'sÂ National Institute of Advanced Industrial Science and Technology. In a country as seismically active as Japan, it was a clear signal that geothermal energy was worth investing in. Â Cont'd...
The president-elect has shown a willingness to alter his views in response to new information. As these charts show, clean energy can help him keep his promises.
The growth in solar has been driven by state-level incentives and steep price declines in building projects. These two drivers are probably not going to stop any time soon.
The good news is that the clean energy genie is out of the bottle for good. Markets must reflect the new reality of low-cost clean energy and clean energy policy preferences.
Laura A. ShepardÂ for Popular Science: Â Picture a giant toilet bowl looming larger than life outside the UN headquarters in New York. It sounds like an absurd scene, but the stunt from three years ago was not a childish prank. It was a serious statement to mark the first World Toilet Day and raise awareness of the fact that one third of the world's population lacks access to toilets. Addressing the global sanitation crisis is a top priority among the UN'sÂ Sustainable Development Goals, and it now has an exciting solution. In fact, science may soon make your toilet bowl a viable alternative energy source. Your flushes can produce two or three gallons of biofuel per year when the wastewater is treated using a process, developed scientists and engineers at the Department of Energy'sÂ Pacific Northwest National Laboratory, called hydro-thermal liquefaction (HTL). HTL emulates the way crude oil forms naturally, when biomass decays under high pressure and heat for millions of yearsâ€Š-â€Šbut it only takes 45 minutes. Â Cont'd...
Many companies don't realize that they can generate their own power on-site and in a cleaner and more cost-effective way.
The renewable and energy efficiency industries have created over 2.5 million jobs in the United States. Solar now employs more Americans than than oil, natural gas and coal combined. The nation's fastest growing occupation is, believe it or not, the wind turbine technician; which is still projected to grow 108% in the next 7 years.
Renewables have now reached such a critical mass, utilities can no longer ignore them as a way to augment their capabilities in producing power cheaper, smarter, better. At this point, the tide has turned for utilities and there is no going back.
Joshua S Hill for CleanTechnica: Â A new study has concluded that transitioning to wind and solar power would be a cheaper option for the United Kingdom to replace its coal fleet than using biomass electricity generation. According to a new study published this week by the Natural Resources Defense Council (NRDC) and conducted by London-based Vivid Economics, which examined the full system costs of renewable energy technologies like wind and solar in comparison to biomass as a replacement for the UK's coal fleet, wind and solar came out as the cheaper option. The UK already uses a lot of biomass for electricity generation, with the report concluding that "biomass supplies the lion's share" of the country's renewable electricity generation. However, as the authors of the report note: "â€¦recent science shows that many forms of biomass produce more carbon emissions than fossil fuels like coal and natural gas-especially biomass from forests-increasing carbon pollution precisely when the United Kingdom aims to rapidly decarbonise its electricity sector."

VTT is seeking a carbon capture technology for Finnish power and heat production plants. The first pilots were implemented, using wood pellets, at VTT's Bioruukki and the results are promising.
For energy traders and utilities, profitability in this complex and evolving market requires a full and complete picture of assets, operations, positions and risk exposures. Too many utilities are still labouring under a painful burden of data management challenges, including lack of automation, multiple disparate systems and data formats.
Umair IrfanÂ for ClimateWire: Â On schedule, on budget. Â It's a tall order for any new technology, but for a commercial carbon capture and storage (CCS) system, it might be the start of a revolution. The Petra Nova carbon capture system under construction at the W.A. Parish Generating Station, a coal-fired power plant southwest of Houston, is slated to go online before the end of the year. The billion-dollar facility will become the largest post-combustion carbon capture system installed on an existing power plant in the world. Systems like Petra Nova that keep carbon dioxide from reaching the atmosphere may become a necessary means to mitigate climate change, and for some utilities, they could offer a lifeline to beleaguered fossil fuel plants.
