Natural gas is meant to be a far lower carbon fuel than coal, writes Steve Horn. But a new study shows that methane leaks from gas power plants and oil refineries are 20-120 times higher than thought. And with methane a greenhouse gas almost 100 times stronger than CO2 over 20 years, the leaks are equivalent to about a tenth of the US's CO2 emissions.
State action on solar power can make a big difference, writes Aaron Viles. Driven by ambitious renewable energy targets and the need to generate local growth industries of the future, five states stand out for their trend-setting policies that are accelerating the US's clean energy transition.
Remarks by Bernie Sanders that climate change is a major driver of global instability and terror, he was mocked by Republican Presidential contenders. But the argument is a familiar one to the CIA and the Department of Defense, which has itself released strong warnings on the issue. Is it time the GOP got with the beat?
The oil and gas industry has admitted that its canals and drilling rigs have destroyed 1,900 square miles of coastal wetlands on the US Gulf Coast, but a Federal Judge with deep industry ties has ruled that 97 companies off have no liability for the $50 billion damage.
The Walton family, owners of Walmart and Asda, project a 'public environmentalism', writes Mike Gaworecki. But their real agenda is to advance a monopolistic corporate economic model that is threatened by decentralised energy solutions like rooftop solar. The answer? Exterminate!
Floating over the US Southwest is a cloud of methane the size of Delaware, writes Mike G - reflecting the release of almost 600,000 tonnes of the powerful greenhouse gas every year. Its origins? Coalbed gas production, fracking and horizontal drilling.
Solar power could be producing over a quarter of the world's electricity within 35 years, according to the International Energy Agency. But in the US, Congress's failure to extend solar tax credits is causing projects to be withdrawn.
Oil majors are gearing up to exploit Arctic oil, writes Mike G. But they don't want to carry the costs of all the safety equipment the US Government is demanding to protect the fragile Arctic environment from spills. And they're reluctant to give up the use of toxic chemical dispersants.
King Coal's reign is coming to an end, writes Chris Rose, at least as a fuel for generating electricity. Following a price collapse half of all production is being sold at a loss - and major coal users like China are still moving away from the high-carbon fuel.
Climate change and tar sands activists opposing Keystone XL need to wake up to a new reality - the pipeline has already been eclipsed by rail transport which is both cheaper and more flexible, writes Justin Mikulka. The expanded production and export of tar sands oil just got a whole lot more likely.
Data collected by the WMO shows there were almost five times as many weather- related disasters in the first decade of this century than in the 1970s, writes Chris Rose. Hurricane Katrina in 2005 was the most expensive ever, costing $147 billion.
California and Texas continue to break new ground in making electricity generation from renewable sources, writes Mike G. Solar PV in particular has become a vital part of the US' energy mix, accounting for half of new generation capacity.
In 2012 'skeptical environmentalist' Bjorn Lomborg told The Ecologist that his Copenhagen Consensus Center had poor funding prospects. But now its US arm is flooded with cash - over $4 million since 2008. And as Graham Readfearn reports, only a fraction of it can be traced ...
After over a decade of fracking, oversight of the industry's radioactive waste is still lacking, reports Sharon Kelly. Over half of the 280 billion gallons a year of radioactive waste water from fracking ends up in rivers and streams.
