Peak Energy by 2030: Efficiency gains will make the Transition affordable
We can’t afford the energy transition? Next time you hear that from someone, perhaps you can show them this. Sverre Alvik at DNV GL explains that, according to their latest Energy Transition Outlook, although annual global energy expenditure will have to increase from $4.6tn in 2017 to $5.5tn in 2050, its share of growing world GDP will almost halve from 3.6% to 1.9%. That’s because continuing energy efficiency gains are making sure that total … [Read more...]
Most “sector leader” German DAX firms will miss the Paris target
By how much would the earth warm up by 2050 if every company were to operate as emissions-intensively as yours does today? It’s a fascinating way to measure whether you are doing enough, or whether you are leaving the hard work to someone else. The fintech "right. based on science" has created a model that tries to answer these questions. They have used it on the 30 companies listed on the German DAX index by calculating the future emissions of … [Read more...]
What can Oil producers learn from a sunset Coal industry?
Although fossil fuels are being replaced by clean energy they are not going away. Even coal is not in decline, it’s just peaked globally: declining in mature economies, still rising in developing ones. Henning Gloystein at the Eurasia Group, writing for the Atlantic Council, asks to what extent oil will follow coal. Oil consumption is still growing – 1% this year - though at a much slower rate than before. As with coal, a re-focus onto cleaner … [Read more...]
How will we pay for the European Green Deal?
The European Green Deal (EGD), announced on December 11th, sets a 2050 target to make the continent become the first to achieve carbon neutrality. It’s a long-term plan – not yet law – to re-design all EU instruments and includes 50 specific policy initiatives. But nobody yet knows how much money is needed, who will pay (or lend) it, and who will get it. So tense discussions will now begin between the likely payers (such as Germany, the … [Read more...]
Next generation Wind rotors: because “supersizing” is reaching its limit
A great deal of the cost reductions in wind energy have come, pure and simply, from bigger turbines. Their rotors have a greater swept area and access higher wind speeds at elevated heights. But there are practical limits to the size these blades can reach. Challenges include weight, fatigue, manufacturing, reliability, transport and logistics. To push the boundaries of design, teams from the U.S. Department of Energy’s National Renewable Energy … [Read more...]
Predicting global air conditioning demand, by nation
Predicting future energy demand is difficult, more so when you must account for the choices made by individual households spread all across the globe. Air conditioning is a case in point. To tackle this, Lucas Davis led a team at the Haas School of Business to quantify each nation’s need for air conditioning, and rank them (219 countries and 1,692 cities). To get a nation’s “total CDD exposure” they, in essence, worked out their average cooling … [Read more...]
The search for “thin film” solar PV: stable, efficient, non-toxic, abundant
Around 95% of the world’s solar modules are made with silicon. It’s stable against temperature and humidity fluctuations and we’ll never run out of it. But it’s quite inefficient at absorbing sunlight, and very brittle. So the silicon layers in PV have to be quite thick to capture sunlight and resist cracking, leading to heavy and bulky solar panels. The remaining 5% of solar modules are “thin film”, opening the way for game-changing lightweight … [Read more...]
Hydrogen’s future: reducing costs, finding markets
Although 100Mt/year of hydrogen is produced globally and at scale, it’s overwhelmingly for the chemical industry. So there’s a long way to go for it to play a role in the energy transition. It’s not even clear whether hydrogen will be best used directly as a power source or through further conversion into other powerfuels. That's why Dolf Gielen and Emanuele Taibi at IRENA are scoping out the challenges of reducing production costs and finding … [Read more...]
2019-2024: competitive auctions will launch over 2/3rds of utility-scale renewables, says IEA
Government support for new utility-scale capacity is being replaced with competitive auctions, the surest sign that the commercial appetite for renewables - particularly solar PV and onshore wind - is growing strong. This article by the IEA pulls out the essential numbers from their annual Renewables 2019 report (their 5-year market analysis and forecast for renewable energy and technologies in the electricity, heat and transport sectors). The … [Read more...]
Distributed Solar: rooftop residential, commercial systems keep getting cheaper
In the U.S., PV module efficiency (median values) rose from 12.7% in 2002 to 18.4% in 2018, much of it in the last decade and a full percentage-point increase in the last year alone. The best modules are even more efficient, says John Rogers at the Union of Concerned Scientists. Improvements have come from manufacturing processes and cell architectures, and the increasing share of more-efficient mono-crystalline technologies: up from 40% in 2016 … [Read more...]
Decarbonising light duty vehicles globally: consumer choice, technology, policy pathways
The MIT Energy Initiative (MITIE) has completed a 3-year study of “Mobility of the Future” to plot a decarbonised pathway for light duty vehicles (i.e. cars) globally. Wide in scope and detail, it covers government policies, consumer choices and technologies, combining their multiple and complex impacts to make their assessments. Kathryn Luu at MITIE reviews the final 220-page report. For consumers, cost, convenience, and — increasingly — carbon … [Read more...]
The coalition for an EU-ETS carbon price floor is reaching critical mass
The EU Emission Trading Scheme (EU-ETS) is bound to play a major role for ratcheting up climate policies in both the EU and its member states. After a prolonged period of low prices that questioned the ETS’s viability, the recent price run upwards in the wake of a major reform has sparked confidence that from now on “everything goes in the right direction”. But this confidence is misguided and ignores major risks for the scheme, argue Michael … [Read more...]
Biofuels: slump in investment and innovations must be reversed
IRENA is predicting the future of liquid biofuels by monitoring the number and technology-type of patents. It’s not looking good. The first thing to note is that, after a promising rise, the total number of patents has slid from over 6,000 in 2011 to around 2,500 in 2017. That’s reflected in the dramatic fall in global biofuel investments, from $27bn in 2007 to $2bn in 2017. The likely main cause is a lack of stable regulation, say Alessandra … [Read more...]
COP25: the “easy wins” are coming to an end. What now?
Lola Vallejo at IDDRI says the impressive wins we’ve seen so far in clean electrification are merely the easy “low hanging fruit”. Other big sectors like transport, buildings and industry have barely started to transition. As COP 25 convenes in Madrid this week, the world will want to know what promises will be made - via each country’s self-imposed enhanced Nationally Determined Contributions (NDCs) - to meet the Paris goals, because the current … [Read more...]
