Our current electricity grid was built hundreds of years ago, when power generation was centralised and our energy needs were far simpler. Electricity was distributed from large stable power plants to the consumers through a unidirectional flow that was easily predictable and did not require complex control. But over the last decades, cities have been going through a substantial change, seeing an exponential increase of their energy needs which … [Read more...]

Scientist’s view: recent energy & environmental news 2/11/19
Energy Friends, once again, a cycle with a lot of news. Here is a digest of the latest edition of the Alliance for Wise Energy Decisions (AWED) monthly newsletter. For the full version click here. … [Read more...]
New tool to show whether companies’ climate strategy matches their public ambitions
By now we’re used to stats that show what would happen if everyone in the world had the same carbon footprint as a European, or an American, someone in China, or indeed anywhere. According to the consultancy right. based on science, they have now created a way of modelling the same projections, except for specific companies. The model also number-crunches a company's climate strategy to work out whether they are going to help or hinder the race … [Read more...]
XDC webApplication for the utility company ENEL S.p.A.
Forward-looking companies have started to individually calculate how many °C would the global temperature increase by, if all companies operated as emission intensely as themselves. For this calculation, they are using the XDC webApplication. Therefore, they have started asking questions like these: How can it be that a company like Apple achieves a standard XDC of "only" 1.49 ° C? How do science-based targets and the XDC model come … [Read more...]
Nuclear – critical choice for 2050
As the urgency of the climate crisis becomes more obvious, nuclear power is drawing another look. The power sector needs to develop to meet climate targets. Renewables (RES) have taken significant share of the energy mix in recent years but going further means securing far more investment and solving the complex challenge of integrating variable power. There is a need for alternatives to run alongside RES, keeping us on track. Matthew Wald from … [Read more...]
Billions in private investment waiting for clearer action and guarantees from governments on pathway to 2050
Last month we reported how weak commitments by some EU states were putting a successful transition at risk. Marcela Scarpellini of right. based on science focuses on how this confusion impacts the funding of the transition, and the essential role of private investment. $16.5 trillion needs to be put into energy efficiency and low-carbon technologies by 2030 to hold the temperature increase below 2°C by 2050, says the IEA. Governments alone cannot … [Read more...]
Renewables losing market share in Africa
Alarming new data shows that coal, liquid fuels and gas are strengthening their grip on Africa’s power sector. Investments in renewables are too slow to keep pace with demand growth. With the ink still drying on Katowice's COP24 agreement, Terje Osmundsen's latest blog post makes for urgent reading... … [Read more...]
IEA: Future is electric and increasingly renewable
"The IEA is no longer the conservative bastion of oil it once was" writes Fereidoon Sioshansi. Distilling all 650 pages of their latest Outlook, he summarises how the pressing need to address climate change means the dwindling supremacy of oil is giving way to a growing role for electricity that will, amongst other things, cater for 1 billion EVs by 2040.

EU should target carbon dioxide removal as part of net zero emissions strategy
Carbon Dioxide Removal (CDR) technologies are still in their infancy. However, they are an essential part of limiting global temperature increases to 1.5-2°C to meet the Paris Agreement’s objectives. So what is the best way to ensure CDR is ramped up at the right speed to hit those targets, and avoid the “moral hazard” of the promise of future CDR giving others an excuse to fail with their straightforward carbon reduction? Oliver Geden, Glen … [Read more...]
A Just Transition – or a transition, but only just?
At COP24 the Polish Presidency has issued a declaration for a "Just Transition". Jennifer Tollman of climate think-tank E3G says a Just Transition must make allies of those working in and dependent on the high-carbon economy by supporting them in the transition. They must not be left behind. But they warn that this support should not be an excuse for a “go slow” on the transition, as missing our global climate targets is a clear disaster. … [Read more...]
Can Teresa Ribera transform Spain into a green champion?
In a draft bill released on 13 November, the Spanish government is proposing to ban fossil fuel subsidies and fracking, reduce greenhouse gas emissions by 20% by 2030 (37% compared to current levels) and 90% by 2050, boost the share of renewables to 35% (70% of power generation) in 2030 and discourage diesel and petrol cars. Natalie Sauer of Climate Home News portrays the woman behind the plan, ecological transition minister Teresa Ribera, and … [Read more...]
We have a decade to prevent dangerous climate change: these 10 policies can save us
The climate change challenge is not technical nor even economic, but a matter of enacting the right policies, writes Silvio Marcacci, Communications Director at San Francisco-based think tank Energy Innovation. Based on new research, Marcacci outlines the the types of policies that are the most effective. … [Read more...]
The IEA comes up short on climate (again)
The release of the World Energy Outlook (WEO) 2018 marks another missed opportunity for the International Energy Agency (IEA) to provide a roadmap to Paris, writes Greg Muttitt of NGO Oil Change International. According to Muttitt, even the WEO’s “sustainable development scenario” falls well short of the Paris goals. Policymakers and investors cannot rely on the WEO to guide their decisions in energy. … [Read more...]
Energy efficiency is more than saving energy: “We need to build a real marketplace”
Energy efficiency experts have come to the conclusion that “selling the business case of energy efficiency on the basis of cost savings is not enough.” If the potential of energy efficiency is to be realised, a real marketplace in projects needs to be built and the “non-energy benefits” of efficiency must be monetised writes Brussels-based journalist Clare Taylor. The European Commission has developed a number of instruments, including a unique … [Read more...]
Coal can’t compete – and its true costs are even higher than they appear
In Texas, income from electricity sales does not even cover the direct costs of coal power plants. But their hidden costs are much higher, explains Daniel Cohen of Rice University in Houston. Courtesy The Conversation. … [Read more...]
