There are many different kinds of energy storage technologies, each with its own advantages and drawbacks. Lithium ion batteries are the most popular form of storage at the moment, but according to Roger Dargaville, Deputy Director of the Melbourne Energy Institute, they are not always the cheapest option. Nevertheless, lithium ion will probably be the dominant option, not because of economics, but because of human behavior. Courtesy of The … [Read more...]
The End of the Energiewende?
The prominent German economist Heiner Flassbeck has challenged fundamental assumptions of the Energiewende at his blog site makroskop.eu. According to Flassbeck, the former Director of Macroeconomics and Development at the UNCTAD in Geneva and a former State Secretary of Finance, a recent period of extremely low solar and wind power generation shows that Germany will never be able to rely on renewable energy, regardless of  how much new capacity … [Read more...]
Australians can have zero-emission electricity, without blowing the bill
Australia, which already has the highest solar PV concentration in the world but still relies heavily on fossil fuels, can move to a zero-emission electricity system while keeping prices low, writes Paul Graham, Chief Economist at CSIRO (Commonwealth Scientific and Industrial Research Organisation).

Open letter to policymakers: make Europe Renewable Energy World Leader by 2020
Europe should embark on a collective project to become the world leader in renewable energy by 2020, write Enrico Letta, President of the Jacques Delors Institute, Herman Van Rompuy, President Emeritus of the European Council and President of the European Policy Center and Bertrand Piccard, pilot of the Solar Impulse, in an open letter to policymakers. Such a leadership effort would go a long way to addressing a multitude of challenges facing … [Read more...]
How utilities can deal with the threat of community energy
Community energy is the next big threat to utility companies â unless they manage to become part of this emerging energy economy. They still have a window of opportunity, says Craig Cavanaugh of software services company Omnetric Group, who spent six months researching the energy community market in Europe and the US. He sees three main opportunities for utilities: they can become âcollaborative partnerâ, âcommunity energy service providerâ or … [Read more...]
Energy may be ripe for the sharing economy, thanks to Bitcoinâs blockchain technology
The marriage of blockchain technology with microgrid applications could transform the way communities and organisations use renewable energy, writes Lexie Briggs of Advanced Energy Economy (AEE), an association of businesses in the US that includes companies such as Vestas, Siemens, Microsoft, GE and Schneider Electric. Siemens has just launched a project in Brooklyn, New York, that allows neighbours to purchase solar power from each otherâs … [Read more...]
Fracking: âGang plank to climate chaosâ or ânecessary part of decarbonisationâ?
Fracking is a threat to the climate and the environment in the UK, says Professor Peter Strachan of Robert Gordon University. No, the climate benefits of domestically produced shale gas outweigh the risks, argues Stephen Tindale, co-founder of consultancy Climate Answers. The two men held a fascinating debate at the Houses of Parliament in London on 29 November hosted by the All-Parliamentary Group on Unconventional Oil and Gas. Ruth Hayhurst of … [Read more...]
South Africaâs new energy plan: postpone nuclear, phase out coal
The much awaited updated South African Integrated Resource Plan for electricity, released for comment on 22 November, has sparked strong emotions, writes Hartmut Winkler, Professor of Physics at the University of Johannesburg. In an article for The Conversation, Winkler discusses the main points of the plan and explains why the nuclear lobby in particular is unhappy. Courtesy of The Conversation. … [Read more...]
DNV GL on risks of renewables: âWe need new tests and standards to prevent major failuresâ
The transition to renewable energy is accompanied by the widespread use of power electronics, such as inverters, which require a whole new way of testing smart equipment, says Theo Bosma, Program Director Power Systems & Electrification at DNV GL, one of the largest technical consultancies in the world. According to Bosma, the new power electronics are not adequately tested at the moment. âNew technologies such as solar, wind, batteries and … [Read more...]
Why sharing solar is the next big thing in energy
The disruption and the opportunities being offered by solar PV and battery storage are likely to be accelerated massively by the introduction of new software such as the âblockchainâ system that has already taken root in financial systems, writes Giles Parkinson of the leading Australian energy website Reneweconomy.

Why China’s new coal plants won’t stop it from meeting its climate goals
In a fascinating article, Collin Smith, graduate student at the Hopkins-Nanjing Center in China, explains why China has been building a large amount of new coal-fired capacity the past two years, despite its climate commitments and drive for renewable energy. He also explains why this capacity does not necessarily translate into more coal power production: the power plants are and will be heavily underutilised. There is a danger though that the … [Read more...]
India wants to become a solar superpower â but its plans donât add up
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. Courtesy of The Conversation. … [Read more...]
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...]
