A new report by the Institute for Energy Economics and Financial Analysis (IEEFA) shows that major power systems are able to cope quite well with increasing shares of intermittent renewables, if the right measures are taken. The study says that increased generation of these renewables does not make the grid less reliable or compromise security of supply. … [Read more...]
Cheap renewables are transforming the global electricity business
Renewables are not yet the least costly option in every market, writes Tim Buckley, Director of Energy Finance Studies Australasia at the Institute for Energy Economics and Financial Analysis (IEEFA), but the pace of change demonstrates that a tipping point toward a new energy economy is coming, and fast.

Energy storage does not always make the electric grid cleaner
Energy storage can help grids use more wind and solar power, but it does not always reduce carbon emissions, write Naga Srujana Goteti, Eric Hittinger and Eric Williams of the University of Rochester. In some cases, adding storage actually even increases carbon emissions. This happens when consumption is shifted to periods when coal power is used more.

Empowering the powerless: here is how we can end energy poverty
Millions of people die prematurely of indoor pollution and other consequences of energy poverty. Centralized power systems have failed them, writes Jatin Nathwani of the University of Waterloo. But there is a way to empower the powerless: with microgrids and decentralized technologies. Courtesy The Conversation. … [Read more...]
Rapid wind and solar cost declines keep pushing fossil fuels out. How far can they go?
Rapid cost declines made renewable energy the United States’ cheapest available source of new electricity, without subsidies, in 2017, writes Silvio Marcacci of think tank Energy Innovation. In many parts of the U.S., building new wind is cheaper than running existing coal, while nuclear and natural gas aren’t far behind, notes Marcacci. As renewable energy costs continue their relentless decline, they keep pushing fossil fuels further from … [Read more...]
French people support energy transition (more than nuclear power)
France is at a crossroads, writes Jules Hebert, program coordinator at the Heinrich Böll Foundation office in Paris. It can pursue a renewed nuclear model – or follow the German example and invest massively in renewable energy. It is often said that the French people support the nuclear path, notes Hebert – but a recent survey comes to a different conclusion.

Should the energy future of the U.S. depend on cheap solar imports?
The decision by the Trump administration to impose tariffs on the imports of solar panels has been widely criticized, as it is seen to undermine the growth of the solar energy sector in the U.S. However, independent energy analyst Geoffrey Styles believes there are some good reasons to support the measure. The Chinese government after all heavily supports its own industry. What is more, if solar power is as important to future U.S. energy supply … [Read more...]
Are renewable energy cost reductions coming to an end? What next?
Renewable energy’s steep cost reductions may be tapering off, as investments levels are flat and system costs are becoming more important than component costs, writes independent energy expert Roger Arnold. According to Arnold,this implies that policy support should shift to storage and infrastructural approaches. … [Read more...]
China takes steps to stimulate distributed renewable energy generation
China’s spectacular expansion of its solar power capacity is mostly based on utility-scale solar, but distributed solar is also taking off, write Max Dupuy and Wang Xuan, two China experts from the globally operating Regulatory Assistance Project (RAP). According to Dupuy and Xuan, this trend may be expected to continue, as the Chinese government is creating new business and regulatory models to stimulate distributed solar PV and other … [Read more...]
Winds of change: Britain now generates twice as much electricity from wind as coal
Just six years ago, more than 40% of Britain’s electricity was generated by burning coal. Today, that figure is just 7%. Yet if the story of 2016 was the dramatic demise of coal and its replacement by natural gas, then 2017 was most definitely about the growth of wind power, write Grant Wilson and Iain Staffell. Courtesy The Conversation. … [Read more...]
Roadmap to nowhere: the myth of powering the nation 100% with renewable energy
Renewables have captured the public’s imagination,but can they actually be scaled up to power the entire nation, ask Mike Conley and Tim Maloney? In their new ebook, available at RoadmapToNowhere.com, they present their reasons why they are convinced 100% renewables is a myth - and why we should rely primarily on nuclear power. … [Read more...]
How to ensure that corporate buying of renewable energy really makes a difference
Many corporations are eager to contribute to the fight against climate change by sourcing renewable energy. Yet, despite some high-profile power purchase agreements, corporate renewables sourcing is still a small market and its real contribution to the energy transition is doubtful sometimes, writes Malte Gephart, energy policy expert at international consultancy Navigant. According to Gephart, this is a missed opportunity. He explains what needs … [Read more...]
Renewables in Africa are losing ground: a proposal for a practical climate finance instrument
If the One Planet Summit in Paris on 12 December is to meet its expectations, it must lead to a new cost- and carbon-efficient instrument to support decentralised renewable electricity generation across Africa, writes Terje Osmundsen, Courtesy Energi og Klima blog. … [Read more...]
The German electricity market in 2016: more gas, renewables stable, higher emissions, higher tariffs
Whereas gas-fired power grew strongly in Germany in 2016, the output of renewables declined slightly. CO2 emissions went up, as did network tariffs and consumer prices. Renewables were funded 70% through auctions and just 30% through feed-in tariffs. An overview by Marius Buchmann. … [Read more...]
The net cost of using renewables to hit Australia’s climate target? Nothing
Australia can meet its 2030 greenhouse emissions target at zero net cost, according to a new analysis of a range of options for the National Electricity Market, write Andrew Blakers, Bin Lu and Matthew Stocks of Australian National University. Courtesy The Conversation. … [Read more...]
