The drive to extract and store CO2 from coal-fired power plants is gaining momentum, with the Obama administration backing the technology and the world’s first capture and sequestration project now operating in the U.S. Two questions loom: Will carbon capture and storage be affordable? And will it be safe? by David Biello, Editor of Scientific […]
The US Environmental Protection Agency (EPA) has announced a $5 million grant to fund US as well as international organizations for reducing global climate pollution.
Yesterday, Clean Edge, Inc., a clean-tech research and publishing firm, released Clean Tech Job Trends 2009. The report provides an investigation of how clean-tech jobs in the U.S. and globally are changing the face of industry, where the hotbeds of growth exist, and whether current clean-tech salaries are living up to their ‘green-over blue-collar’ promise.
The AlwaysOn Network recently announced their Third Annual List of the GoingGreen 100 Top Private Companies of 2009. The award recognizes the top private greentech companies that are creating new business opportunities and transforming the world’s largest industries to improve sustainability.Among the hundreds of companies evaluated, They selected the Oakland California-based, Brightsource Energy, a provider of solar energy to utility companies, as the overall winner.
Senior members of the US Chamber of Commerce are strdently opposing the Chamber’s position of opposition to climate policy. These organizations are eager “to boost their green credentials,” for fear of alienating their customers and senators. This is an indications that Social movements shape political power and concerned citizens, can move even the most entrenched corporate and political interests. NRDC research finds that “only 23 members of the U.S. Chamber’s board have a publicly stated position on climate change and more than 80 percent [19 members] are not on board” with the Chamber’s official position.
Seriously folks you read it right… fracking (an actual technical term for hydraulic fracturing) hot dry rock reservoirs has the potential to open up vast hot dry rock “heat” reservoirs for use as a reliable geothermal energy source. According to a 400 page MIT study The Future of Geothermal Energy sponsored by the Department of Energy (DOE) and published in 2007 the economically recoverable potential for “Heat Mining” in the US could grow to a cumulative installed generating capacity of 100GW in less than fifty years.
The world stands to gain 6.9 million jobs by 2030 in the clean energy sector if a strong deal is reached in Copenhagen, according to a report released recently by Greenpeace International and the European Renewable Energy Council (EREC). A switch from coal to renewable electricity generation will not just avoid 10 billion tons of CO2 emissions, but will create 2.7 million more jobs by 2030 than if we continue business as usual. Conversely, the global coal industry – which currently supports about 4.7 million employees worldwide – is likely to contract by more than 1.4 million jobs by 2030, due to rationalization measures in existing coal mines.
Distributed energy systems can range from the micro sized do it yourself systems being installed on rooftops and on hilltops to small scale systems ranging up to around 20MW (megawatts) of capacity, although it must be understood that this is a pretty fuzzy boundary. The defining characteristic of distributed energy systems is that they generate energy close to the point of use where that energy will be consumed; hence the admittedly fuzzy 20MW upper boundary for their size.
The sun can help coal fired power plants burn less coal by pre-heating the water used to make high pressure high temperature steam during periods when the sun is shining. In other words the sun would do part of the work of producing high pressure/ high temperature steam and in this manner the overall hybrid solar/coal power plant would use less coal than a coal only power plant would need to produce the same amount of electric power.
