Stanford professor Mark Jacobson and his colleagues have written yet another paper purporting to show that 100 percent of energy demand can be fulfilled by wind, solar, and hydroelectric generation. This latest study, which comes in the form of a manuscript accepted but not yet published by the journal Renewable Energy, seeks to show how that goal can be met in 139 nations.[Read More...]
Last month the Power Finance Corporation of India (PFC) issued a so-called green bond in London. It is a 10-year green bond and raised USD 400 million, paying a 3.75 per cent semi-annual coupon and listed on London Stock Exchange’s new International Securities Market (ISM).

At the end of last month, Tesla boss Elon Musk held a party in South Australia’s mid-north. It seemed premature, but Musk was typically confident. Construction on what will be the world’s most powerful lithium ion battery was going well. It had to. Musk has made a self-testing gamble with the South Australian government: complete the project within 100-days and[Read More...]
At the People’s Climate March back last spring, all along that vast river of people, the atmosphere was electric. But electricity was also the focus of too many of the signs and banners. Yes, here and there were solid “System Change, Not Climate Change” – themed signs and banners. But the bulk of slogans on display asserted or implied[Read More...]
Some people in South Florida are finding it difficult to flee Irma because they cannot fill their tanks up with gasoline. Many gas stations are shuttered. Others have extremely long lines.
But people with electric cars such as a Chevy Bolt or Tesla 3 do not need gasoline. At least until the hurricane hits, they have electricity and can fuel their automobiles with it.
The new generation of electric cars gets over 200 miles on a charge.
The Indian economy is heavily dependent on coal. Infamous as the world’s fourth largest polluter, India’s current energy mix has an enormous proportion of coal. Close to 60 % of power supply is derived from coal fuelled power plants. Consequently, in 2016, half of the country’s emissions – 805.4 million tonnes – came from the power sector. However, for the[Read More...]
Illustration from the recent paper by Olivia Judson on “Nature Ecology & Evolution (2017) “The Energy Expansions of Evolution”. Olivia Judson published a very interesting paper this March on “Nature Ecology & Evolution“. It is a wonderful cavalcade along 4 billion years of the history of the Earth, seeing it in terms of five “metabolic revolutions.” It is an approach that goes in[Read More...]
Scientists unanimously agree that massive quantities of greenhouse gases released from combustion of fossil fuels are primarily responsible for global warming and have unleashed an internecine cycle of melting polar ice and thawing permafrost which greenhouse gases and further warm up the earth’s temperature. They warn that the present fossil fuel based economy is unsustainable and if efforts are not[Read More...]
Aspects and Causes of the Crisis The climate crisis is only one aspect of the global crisis. Yet, generally speaking, Western governments, media, politicians, NGOs, and publicists have been trying to make us believe that it is the only dangerous and the only global crisis. It appears that for them all other crises in the world are only partial or regional problems of secondary[Read More...]
Around 2,000 wind power stations in Sweden provided 7.1 TWh of electricity in 2012 alone.(Trons/Scanpix)
The government has come under fire over its ‘short-sighted decision’ to effectively ban new onshore windfarms after the release of a report that shows they could actually produce the cheapest electricity in the country — even cheaper than gas.
