With adversity comes opportunity. The global gas crunch has hurt countries around the world but has also made them appreciate their common concerns. That has provoked policy-makers to take a serious look at current and future energy security policies. In the EU the competitive gas markets, enabled by short-term spot markets, has reminded us of the value of long-term contracts when prices are volatile and rising. Meanwhile, China’s … [Read more...]
Turkey: when electricity price ceilings amplify the pain of gas spikes and currency falls
Turkey’s rules for an electricity price ceiling may be well intentioned, but they are creating a price ladder that is causing those prices to rise too fast and too much, say Fuat OÄźuz at Ankara Yıldırım Beyazit University and ÇaÄźrı Peker at the Energy Market Regulatory Authority, Turkey. When market participants are allowed to sell and buy electricity at distorted prices the effects of external shocks are amplified artificially. The main shocks … [Read more...]
Avoiding renewables bottlenecks needs long term planning of electricity transmission infrastructure
As more renewables are rapidly added to grids, network operators must plan new transmission lines to integrate them immediately, avoiding wasteful bottlenecks. It’s a puzzle that’s getting bigger and more complex as the energy transition gains pace, which means transmission policy and planning must improve, and fast. Rather than making lots of small incremental steps, planning ahead will prove less costly and capture efficiencies and economies of … [Read more...]
Electricity Market Reform: ACER must empower consumers, not just network operators
ACER, the EU Agency for the Cooperation of Energy Regulators, has delivered to the EC its preliminary assessment of Europe's high energy prices and the current wholesale electricity market design. Simon Skillings and Lisa Fischer at E3G interpret ACER’s assessment as showing it wants to maintain the status quo. However, long-term changes in market design are inevitable. The authors want ACER to accept this reality and ensure the changes are … [Read more...]
Surging U.S. renewables on track to take 30% market share by 2026
While the U.S. Congress debates whether backing the transition is a winning strategy, the energy sector is clearly showing the nation’s direction of travel. Dennis Wamsted and Seth Feaster at IEEFA look at the impressive growth of the clean energy champions, wind and solar. Since 2019, wind and utility-scale solar generation has risen by 76 TWh — a 31% increase — while coal and gas has fallen by 1.6%. By 2026, wind and utility-scale solar will … [Read more...]
Energy professionals: do you understand how the media works?
We energy professionals spend most of our time talking to each other. But, more than ever, climate change and the energy transition are headline news. That’s not just in the mainstream media but also within our industry journals and the policy-maker press. So, we need to understand how the media works. More specifically for many, we need to know how to handle our PR providers. Sean Crowley says it’s up to us to work more effectively with the … [Read more...]
CEPP incentives and penalties: current design could undermine U.S. clean energy growth
The Clean Electricity Performance Program (CEPP) is a key part of President Biden’s energy and climate plans. It will steer utilities towards clean energy with incentives and penalties, and is still being designed. Severin Borenstein and James Bushnell at the Energy Institute at Haas, Steve Cicala at Tufts University and Ryan Kellogg at the University of Chicago warn that current proposals will allow utilities to game the system, resulting in … [Read more...]
Next German government’s climate and energy plans: what will Olaf Scholz do?
Olaf Scholz led Germany's Social Democrats (SPD) to an unexpected win in the 2021 elections held in September. He now needs to finalise a coalition with the Green Party and the pro-business FDP before forming a government and becoming chancellor. Like his predecessor Angela Merkel, Scholz has said he wants to become a "climate chancellor". Kerstine Appunn and Benjamin Wehrmann at Clean Energy Wire try to understand what his climate and energy … [Read more...]
Ice for storage for intermittent renewables, then for cooling
Cooling accounts for around a fifth of total energy consumption in buildings. All those air conditioners and electric fans make up a tenth of all global electricity consumption. Demand will keep rising as developing nations get wealthier. Andrea Willige, writing for the World Economic Forum, looks at ice as a seemingly simple solution. Ice can be used as an energy store like a battery, to balance the grid. Create it when energy is cheap (at … [Read more...]
The U.S. now needs a Carbon Tax to transition from Gas to Renewables
Gas emissions must be halved (and coal eliminated) by 2030 to meet President Biden’s goal of a carbon free power sector by 2035. The problem is that gas additions are half the price of new wind and solar installations. Though the clean energy champions are still getting cheaper, so are gas additions. Nikos Tsafos at the Center for Strategic and International Studies looks at the policy options over the next decade for the U.S. The stark fact is … [Read more...]
New thermoplastic blades for coastal Tidal Energy turbines
Large-scale tidal power turbines provide an option for clean energy generation that doesn’t depend on the weather, like wind and solar. Research led by NREL is using, for the first time anywhere, thermoplastic composite blades that will improve fatigue performance over typical epoxy blades, can be manufactured faster and more energy-efficiently, and can be recycled. The test site is located in New York City's East River, installed in Verdant … [Read more...]
Record global power sector emissions by 2022, because Renewables aren’t growing fast enough
The IEA is forecasting that renewables will cover only half the projected increase in global electricity demand in 2021 and 2022. Despite renewables’ impressive growth, coal and gas will be needed to cover the rest. That means emissions will rise to record levels. That will be the reverse of the IEA’s (and many others’) “Roadmap to Net Zero by 2050” pathway, where three-quarters of global emissions reductions between 2020 and 2025 come from the … [Read more...]
Hydrogen production in 2050: how much water will 74EJ need?
There’s no point ramping up hydrogen if other resource constraints are going to bring it to a halt. Here, Herib Blanco at IRENA summarises their research into how much water will be needed in the production of hydrogen through electrolysis (i.e. from water) and the costs involved. A wide range of analyses have been reviewed to calculate the amount of water used during the hydrogen production, and by the energy source used to power it (renewables … [Read more...]
Wind, Solar: continuing cost declines will help meet rising renewables targets
The EC’s “Fit for 55” proposals include the raising of the EU’s 2030 target for total energy produced from renewable sources to 40%. Much of the rest of the world will likely raise its targets at some point too. Continuing to cut the cost of renewable energy generation will be essential to make that happen, and take pressure off all the other associated costs of supporting its integration into the energy system. Michael Taylor at IRENA summarises … [Read more...]
‘Fit for 55’ should prioritise decarbonisation of laggards: buildings, transport, industry, agriculture
Today’s long-awaited "Fit for 55" legislative package from the European Commission will trigger intense and difficult negotiations that will last two years, says Nicolas Berghmans at IDDRI. Its scope is wide and inevitably interconnected. The twelve legislative proposals include adjustments to existing measures (renewable energy, energy efficiency, carbon market/EU ETS, energy taxation, climate effort sharing between Member States/ESR, land use … [Read more...]
