I was only partially surprised to read in MIT's Technology Review that Amyris, a biotechnology company developing renewable diesel and jet fuel from sugar cane, was backing away from the biofuel market to pursue more lucrative products. Fuels are a highly competitive, low-margin business, and it's hard enough to make money refining them... [read more]

A common analogy to explain the link between climate change and extreme weather is gambling with “loaded dice.” For people who aren’t the gambling type but love America’s pastime, perhaps Barry Bonds’ homerun statistics would be more enlightening, or at least more entertaining. A new video from the National Center for Atmospheric... [read more]

Go ahead -- call me a hypocrite. I claim to be a cleantech venture capitalist yet I tell you here and now that I am not convinced of anthropogenic (human-caused) climate change (aka global warming). And I will audaciously tell you that my convictions on climate change in no way run contrary to my strong belief in the need for a cleantech revolution. [read more]

After going into sudden-death overtime, the UN climate conference in Durban, South Africa wrapped up this weekend with an agreement that only a climate diplomat could love. Constituting in effect an agreement to agree to some future agreement, the outcome is open to interpretation. Is this the failure that was widely predicted, the... [read more]

From Reuters and other sources comes the simply underwhelming news that China climate goals run against growth: report: China, the world’s biggest carbon dioxide emitter, will meet near-term goals to fight climate change but quick economic growth will mean C02 emissions will be higher than previously thought, researchers said on Tuesday...

As global natural gas production has risen and shale gas in the US impacts on the energy outlook for that country in particular, there has been increasing discussion about the impact of natural gas on climate change. Several scientific papers have recently been released questioning the carbon dioxide benefits of natural gas over coal in power production. [read more]

I've been asked to comment on William Happer's "The Truth about Greenhouse Gases", and finding no competent discussion of it anywhere on the first three pages of hits have agreed to take it on. To give you an idea of the tenor of the document, it starts off modestly, like this: “The object of the Author in the following pages has been... [read more]

Energy impacts after Fukushima

In a country with limited natural energy sources, security of supply has been the traditional energy source consideration, although more recently this has been augmented with greenhouse gas emission targets. In terms of primary energy demand for electricity production, data for 2008 from the IEA shows a 3+ way split – the key components being gas, coal and nuclear. Oil products (e.g. fuel oil) are a further important part, followed by much smaller contributions from renewables, waste, biomass and geothermal. Now, nuclear risk will likely figure as a key issue in determining the national energy mix. [read more]

My thoughts and prayers have been and will continue to be with the people of Japan. Their suffering is both a tragedy and testimony to the fragility of even the most developed infrastructure. It is also a reminder of the sometimes alarming ubiquity of our energy supply system. Almost a year after the Deepwater oil spill began in the... [read more]
