India aims to build 1 terrawatt of global solar power â four times the current worldwide total â and become a 100% electric vehicle nation by 2030. Those are great ambitions, but they still far short from what is needed for a true energy transformation away from coal, writes DĂ©nes Scala of Lancaster University.

Reinventing Fire in China
Amory Lovinsâ Rocky Mountain Institute, backed by Chinese institutions and Lawrence Berkeley National Laboratory, has published a stunning roadmap for an energy revolution in China. If its ideas are taken up, it could lead to a transformation of the largest energy economy in the world â and serve as a model for other developing nations to follow, writes Fereidoon Sioshansi, president of Menlo Energy Economics and publisher of the newsletter … [Read more...]
Why the future belongs to decentralised renewables, not centralised hydrogen and giga-scale nuclear
What the future of our energy system will look like continues to be a subject of heated debate. According to one well-established tradition, writes Professor John Mathews of Macquarie University in Australia, the route to decarbonisation will run via massive nuclear power systems to the hydrogen economy. But China and to some extent India are emerging as the principal practitioners of an alternative vision of energy growth, underpinning their … [Read more...]
Stephane Quere, Innovation Director Engie: âHydrogen is a big topic for usâ
Hydrogen, which can be used to store energy, produce electricity and fuel vehicles, is one of the innovation priorities for French energy giant Engie (âŹ70 billion revenue). This is a company that prides itself on its diversity however, explains Stephane Quere, Innovation Director at Engie, with activities stretching from Europe to Africa and Asia, and businesses from gas distribution to security systems. Some of the main priorities for Engie are … [Read more...]
IEA in the Age of Trump: policies will determine where we go from here
The most important message from the 2016 edition of the annual World Energy Outlook, the International Energy Agencyâs (IEA) flagship publication released today, is that âpolicies will determine where we go from hereâ. âParisâ has given the international energy sector âa new sense of directionâ, notes the IEA. But much stronger policies are needed to keep global warming limited to 2 degrees Celsius, it adds. Its message takes on extra importance … [Read more...]
Biofuels turn out to be a climate mistake
Biofuels are usually regarded as inherently carbon-neutral, but once all emissions associated with growing feedstock crops and manufacturing biofuel are factored in, they actually increase CO2 emissions rather than reducing them, writes John DeCicco of the University of Michigan. According to DeCicco, biofuels are actually more harmful to the climate than gasoline. Courtesy of The Conversation. … [Read more...]
Europeâs renewable transport targets need biofuels, they canât be met with EVs alone
The decarbonisation of the transport sector presents a huge challenge for Europe, writes Paul Deane of the Environmental Research Institute in University College Cork, Ireland. Many people believe electric vehicles (EVs) are the answer, but according to Deane biofuels will need to deliver most of the targets for the time being. âEVs will have their day but it may be further down the road than we hoped.â … [Read more...]
Lumenaza creates regional electricity markets: âWe want to connect up all 1.4 million solar PV producers in Germany with consumers locallyâ
A new software platform in Germany lets utilities buy and sell âregional electricityâ by connecting up small producers with consumers. Start-up Lumenaza, founded three years ago, meets a growing demand for transparency, explains CEO and founder Christian Chudoba in an exclusive interview with Energy Post. Unlike a typical virtual power plant, Lumenaza targets tiny producers such as owners of rooftop solar. Its goal is to connect up all of … [Read more...]
We canât simply bet on renewable energy to stop global warming
Simply switching to renewables alone will not solve the climate change problem, writes Steffen Böhm, Professor in Organisation and Sustainability at the University of Exeter. We need to start removing carbon from the atmosphere. And we need to tackle the demand side. We cannot simply assume that relentless economic growth is compatible with a green future. Courtesy of The Conversation. … [Read more...]
The five S’s that will define the new energy order
Digitalisation has already had a huge impact on the energy sector, yet we are only at the start of a revolution that will rip apart any business that is too slow to embrace it, writes Gerard Reid, founding partner of Alexa Capital, financial analyst and co-founder of the Energy and Carbon blog. According to Reid it is the combination of five Sâs â software, semiconductors, sensors, solar and storage â that will define the new energy order. And it … [Read more...]
Peak car ownership will speed up peak oil demand
In a new report, the Rocky Mountain Institute makes the stunning prediction that car ownership will peak by 2020. New ownership models and technological advances such as driverless cars will utterly transform the mobility market, concludes Fereidoon Sioshansi, president of Menlo Energy Economics and publisher of the newsletter EEnergy Informer. The big casualty will be oil companies, which are still in denial. … [Read more...]
The slow death of fast reactors
Generation IV 'fast breeder' reactors have long been promoted by nuclear enthusiasts, writes Jim Green, editor of Nuclear Monitor, but Japan's decision in September to abandon the Monju fast reactor is another nail in the coffin for this failed technology. According to Green, fast reactors arenât becoming mainstream, despite the claims of nuclear lobbyists. … [Read more...]
Peter Carlsson, business angel (ex-Tesla): âBattery breakthrough 5-8 years awayâ
Europe is behind the US and Asia in battery development, but it can catch up if it sets aggressive goals and tough standards, says  California-based entrepreneur and investor Peter Carlsson. After leaving Tesla Motors last year, the supply chain expert is helping a host of cleantech start-ups profit from the energy transition. Within 5-8 years, batteries will break through big-time, he predicts. Grid storage will be done in stationary batteries … [Read more...]
Why most âgreenâ electricity in Europe isnât green
Brussels is on course to deliver a big shake-up of the EUâs energy markets this December by trying to put consumers in the driving seat of the energy transition. Millions of consumers have already made the switch to âgreenâ electricity tariffs. Or so they think. But these tariffs are misleading and consumers are, in many cases, actually supporting fossil fuels or nuclear plants which are hidden behind a green façade, writes Jörg MĂŒhlenhoff, … [Read more...]
Hereâs how to build 100% clean renewable energy in the US before 2040
There really is a feasible way to build our way out of the climate crisis in time to avoid the worst effects of global warming, writes Tom Solomon of 350 New Mexico. We do it by rapidly replacing all fossil fuel-based energy with renewable energy built with current technology, installed in a smart grid. We pay for it without damaging the economy and actually save money vs. our current reliance on fossil fuels. The âside benefitsâ include cleaner … [Read more...]
