New technologies are coming on stream that can turn sunlight and wind into liquid fuels for vehicles, homes or power plants, writes Chris Goodall. And by powering the process using 'free' renewable energy on sunny or windy days, the fuel will be as green as can be, and cost less than petroleum.
As global temperatures reach new monthly highs and the Middle East is hit by record heatwaves, we might be forgiven for sliding into hopelessness, writes PAUL ROGERS. But a host of innovations in energy technology means that a carbon-free energy future is not just possible, but affordable. The first of the three paradigm shifts required to transform the climate change outlook is in place.
The government's surprise delay in signing the contract with EDF to build the Hinkley C nuclear power station has opened up a the space for a forward-looking UK energy policy, writes Jonathon Porritt - one that moves us into the world of low cost renewables, and smart new technologies vital to the global clean energy transition. But is Business & Energy Greg Clark for real? Don't rule it out!
Hugh Fearnley Whittingstall has a done a great job exposing the scandal of Britain's billions of non-recyclable coffee cups, writes Rhodri Jenkins. But what about the coffee itself? The grounds can be used for everything from compost and biodiesel to boutique chemicals and supercapacitors - yet the vast majority of the world's 9m tonnes a year of waste coffee ends up in landfill.
French energy giant EDF will today give the formal go-ahead for the Hinkley C nuclear power station in Somerset, writes Chris Goodall. But that's no reason for the UK to sign up to a disastrous deal that will cost us over £1 billion per year for 35 years - money that should be used to support the green technologies of the future.
When Theresa May proclaims in Parliament that we need the £200 billion Trident nuclear missile system to see off the North Korean nuclear threat, writes David Lowry, just bear this in mind. It is a threat that the UK, global nuclear proliferator in chief, created in the first place, providing both the reactor technology and vital centrifuge materials to make North Korea's nuclear dream come true.
Solar is already the cheapest available power across large swathes of the tropics, writes Chris Goodall - its cost down 99.7% since the early 70s. Soon it will be the cheapest electricity everywhere, providing clean, secure, affordable energy for all.
The idea that our profit-oriented, growth-driven economic system can deliver a sustainable society is a beguiling one, write Lili Fuhr, Thomas Fatheuer & Barbara Unmüßig. But it is doomed to failure. The changes we need are in the first place political, and will be driven by a new democratic will to put people and planet before money.
Renewable electricity is already undermining the big energy utilities' business model, writes Emma Howard, breaking their monopoly and bringing down energy bills. But with the unfolding battery revolution, it's going to reach a whole new level as wind and solar powered families and communities become ever more self-sufficient, leaving utilities high and dry.
In the face of repeated attempts by the UK government to suppress the nation's solar industry in favour of fracking and nuclear, Jeremy Leggett tells the story of how the solar company he founded in 2000 has not just survived, but driven forward with technical innovation - including its new 'Sunstation' - an integrated 'snap-on' solar generation design that elegantly embeds into roofs.
Those opposed to the mass release of GM crops and foods inadequately tested for health and ecological safety are routinely accused of being anti-science, writes Elizabeth Henderson. But it's the GM corporations and their academic allies that are suppressing scientific research, and organic farmers that are building alliances with independent scientists for a future of safe, healthy food.
Critics of renewable energy sources like wind and solar claim that they are inefficient, unreliable and need to be backed up by coal and gas, writes David Elliott. But we have the technology to match green power supply and demand at affordable cost without fossil fuels - by deploying the 'smart grid', using 'green gas' made from surplus power, and raising energy efficiency.
We all know that coal and steam vanquished over water power in Britain's - and the world's - industrial revolution, writes Irma Allen. But as Andreas Malm sets out in his fascinating new book, the deciding factors in that victory were the unconstrained mastery over people and nature that coal provided mill owners. And so the model was set for the fossil age that may only now be coming to an end.
The Chernobyl sarcophagus which has long contained the fissured reactor core is at risk of collapse, writes Claire Corkhill. The solution: build a pair of tracked arches 260m wide and 100m high, and slide them over the site to enclose it for a century to come: so creating a sealed space for robots and remotely operated machinery to deconstruct the reactor and sarcophagus piece by radioactive piece.
The very term 'genetic engineering' implies high precision in the alterations made to genes and deep understanding of their consequences, writes Jonathan Latham. In fact, we have never had either. And even with the arrival of CRISPR and other 'gene editing' systems, that remains the case: technologists are thrashing about in a perilous sea of unfathomable complexities and unknowable outcomes.
The EU Commission has caved in to US pressure in TTIP trade talks by deciding to consider organisms modified by new 'gene editing' techniques as non-GM - in violation of the EU's own laws. The move could make the 'new GMOs' exempt from labeling and from health and environmental testing.
Consumer environmentalism aligns conservation with modern consumer culture, writes Paul Jepson, offering NGOs the means to reach new people and generate new funding streams. But it risks ever more shallow public engagement and digital activism where masses of people back 'solutions' that only make themselves feel good.
Don't believe the spurious claims of nuclear shills constantly doing down renewables, writes Mark Diesendorf. Clean, safe renewable energy technologies have the potential to supply 100% of the world's electricity needs - but the first hurdle is to refute the deliberately misleading myths designed to promote the politically powerful but ultimately doomed nuclear industry.
GMOs have been in our diets for about 20 years, writes Rupert Read. Proof that they are safe? No way - it took much, much longer to discover the dangers of cigarettes and transfats, dangers that are far more visible than those of GMOs. On the scale of nature and ecology, 20 years is a pitifully short time. To sustain our human future, we have to think long term.
The nuclear industry is forever reinventing itself with one brilliant 'new' idea after another, Amory Lovins wrote in this classic 2009 essay. But whether it's touting the wonders of future SMRs, IFRs or LFTRs, the reality never changes: the reactors they are building right now are over time, over budget and beset by serious, entirely unforeseen technical problems.
Koide Hiroaki has spent his entire career as a nuclear engineer, and has become a central figure in Japan's movement for the abolition of nuclear power plants. He met with Katsuya Hirano and Hirotaka Kasai to discuss the catastrophic nuclear meltdowns at Fukushima Daaichi in March 2011, and the crimes and cover-ups committed both before and after the event.
Improved technology and falling costs are moving electric car sales into the fast lane as manufacturers seek achieve significant economies of scale, writes Kieran Cooke. And now China is leading the EV charge with its plans for 5 million plug-in vehicles by 2020.
An occupation of EDF's site office for Hinkley C turned into a celebration today as the EDF Board postponed its 'final investment decision' for the tenth time. With strong opposition among French unions and the project afflicted by severe technical and financial problems, it's not just Hinkley that's going down, but the UK's entire nuclear programme.
Advanced new catalysts are poised to stimulate a clean energy revolution, writes Tim Radford. An organic replacement for the precious metal platinum would allow surplus electricity to be cheaply converted into hydrogen fuel, then burnt in low cost fuel cells to propel 'green' vehicles and generate power on demand.
